Review CORNELL DUBILIER Mica 0.001uf 4500v Type Amps Capacitor Ham Radio

The 681a-15 Cornell Dubilier Mica Capacitor is a high-quality electronic component designed for use in various applications, particularly in ham radio systems. This capacitor features a capacitance value of 0.001 F (microfarads) and a voltage rating of 4500 volts, making it suitable for high voltage applications.

The capacitor is made of mica, a natural mineral known for its excellent electrical insulation properties. Mica is also resistant to high temperatures and humidity, making it an ideal material for capacitors used in radio frequency (RF) circuits. The 681a-15 model is a fixed capacitor, meaning its capacitance does not change with voltage or temperature.

The 681a-15 Cornell Dubilier Mica Capacitor is designed with a leaded terminal for easy installation and connection to other components. The terminal is made of a robust material that can withstand the high voltage and currents typically encountered in ham radio systems.

Cornell Dubilier is a well-known and trusted manufacturer of electronic components, known for its commitment to quality and reliability. The 681a-15 model is no exception, with its tight tolerances and high-quality construction ensuring consistent performance over time.

In summary, the 681a-15 Cornell Dubilier Mica Capacitor is a high-voltage, fixed capacitor made of mica, suitable for use in ham radio systems. Its leaded terminal and robust construction make it easy to install and reliable in operation. With its high-quality materials and manufacturing processes, this capacitor is an excellent choice for any ham radio enthusiast looking for a reliable and long-lasting capacitor for their radio frequency circuits.

1. High Voltage Rating: The capacitor has a voltage rating of 4500V, which is ideal for ham radio applications that require high voltage.

2. Reliability: Mica capacitors are known for their long-term reliability and stability. They are not affected by temperature changes or aging, making them a good choice for applications that require a steady capacitance over time.

3. Low ESR: The capacitor has a low Equivalent Series Resistance (ESR), which means it can deliver high current without heating up. This is important in ham radio applications where high current is required for transmitting and receiving signals.

4. Low Leakage Current: The capacitor has a low leakage current, which means it can hold a charge for a long time. This is important in ham radio applications where the capacitor is used to store energy for transmitting signals.

1. High Cost: Mica capacitors are generally more expensive than other types of capacitors, such as ceramic or electrolytic capacitors.

2. Large Size: Mica capacitors are typically larger in size than other types of capacitors. This can make them difficult to fit into small ham radio projects.

3. Limited Availability: Mica capacitors are not as widely available as other types of capacitors. This can make it difficult to find replacements if the capacitor fails or if a larger capacity is needed.

Conclusion: The 681A-15 Cornell Dubilier mica capacitor is a reliable and high-performance capacitor for ham radio applications that require high voltage and low ESR. However, its high cost and large size may be a disadvantage for some users. If cost and size are not a concern, this capacitor is a good choice for ham radio applications that require high performance. If cost or size is a concern, other types of capacitors may be a better choice.

Recommendation: If you are looking for a reliable and high-performance capacitor for ham radio applications, the 681A-15 Cornell Dubilier mica capacitor is a good choice. However, if cost or size is a concern, consider other types of capacitors, such as ceramic or electrolytic capacitors, which may be more affordable and easier to fit into smaller projects. Ultimately, the best capacitor for your ham radio project will depend on your specific needs and budget.

Details:

When using the word matched it means in test results rather than cosmetic looks.

In regards to the case or cover, then cover is just holding itself together. All tubes purchased have loads of life left in them.

I take lots of pictures so you can see cosmetics.

May be good or above. Slightly heavier than above.

Please realize when buying antique, vintage or used equipment that they cannot be in an absolute mint perfect condition, might need some service, now later. Then they are not included in the sale.

I have 4 of these machines and all display a slightly differing value if test the same tube, as two testers are never. Very good - used light scratching to both the case and CD record. May be very light scratching but not noticeable or the case cover scuffed a little excellent ware to both CD record.

It is up to you make a judgment call and decide if worth the risk of buying. Then I have not test it. I am quite harsh on what is good and bad.

Use the zoom function and have a good look. I may have the same tube but from differing years matched up in test results, which means they cosmetically or internally look a little different.

Please have a look at the pictures for cosmetic condition. Very good plus - used, some light scratching to either the case or CD record. So to recap. The numbers letters in parentheses are equivalents put to help people find correct tube.

I also pack well.

So this shows what I get, and you get may be slightly different. I make mistakes once in a while. If it does not say matched then please do consider them to be such.

Sorry for you having to read this but would be surprised how many people think the items come with my table or a part of anatomy that I have accidentally caught on camera. Or if this is in grading regard to the case cover then there may be cracks torn has rips along its edges scuffed quite badly. New - unopened brand new, sealed. 01nf as shown in pictures.

Photos shown in this listing are of the actual item for sale.

In these cases it is best buying on as if was broken. Fully working. If I say untested.

Whilst I endeavor to put tubes together from the same year and look same, this is not always case. Fair - the CD. Record plays, sometimes skips. This is a process, and it takes time.

Heavy scratching to the disc. Via messaging.

I use a tv7 u military spec tester which is calibrated try to resolve any issue both our best interests. We check and describe the as much of functionality can. As shown in pictures.

001uf 4500v type 681a amps capacitor ham radio tested at If not fully tested, then items are to the full extent and may have something wrong that I discovered. By buying on this item you agree to these stipulations and follow the instructions of post office, or carrier.

Cd record does not play. Rectifiers and diode tubes do not have trans conductance values.

Vacuum tube testing I do not sell just passable tubes. Please not my meter is included in the offer.

In regards to the case cover then this grading means or sleeve is badly torn, scuffed, cracked and falling apart. That is what they are there for.

I also sometimes use a Hickok 752 for testing if state any values they are guide only. Or have only gone so far to test it. Cover is in good condition but has normal wear and tear.

This offer is for a. If it does not say base, stand, table in either the main body of or title. If fully tested then that is what they are. They will normally want to see the item and packing.

I do not publish test results in the listing as what get, and someone else might get can be different. Light and medium scratching. Most have one.

In photographs we occasionally use props to display items the best light possible. It is impossible to describe every scratch, scuff or mark.

Like new - used but no obvious signs of use. It is just my opinion and I would rather paint a bleaker picture of something than saying better. If you're unhappy with an item.

Medium to heavy scratching. I am human.

All tubes have passed the gas and short tests. I am not a huge retail outlet. Light scratching to the case cover.

Low and weak tubes are unceremoniously thrown in the nearest trash can, unless they collectors items. So take a good look. This means that I have tested something not to its full extent.
