Review JOHNSON CONTROLS Air Variable Capacitors

The 189-5-5 Johnson Air Capacitors are a high-quality electronic component designed for use in various applications. These capacitors are specifically categorized as "air" capacitors due to the dielectric medium they utilize, which in this case is air.

The 189-5-5 designation refers to the capacitance value, voltage rating, and physical dimensions of the capacitor. The "189" denotes the capacitance value, which is approximately 189 microfarads ( F). The "5" indicates the voltage rating, which is 5 kilovolts (kV). The "5" in the part number also represents the physical height of the capacitor in inches.

Johnson Air Capacitors are known for their reliability and longevity. The use of air as a dielectric medium ensures that the capacitor can withstand high voltages without the risk of electrical breakdown, making it an excellent choice for power supply applications. The capacitor's design also allows for a low inductance, which is beneficial in applications requiring fast voltage changes.

The 189-5-5 Johnson Air Capacitor is a cylindrical device with a diameter of approximately 3.5 inches. It is constructed from high-quality materials, including a reinforced aluminum can and a porcelain end cap, ensuring durability and resistance to environmental factors. The capacitor is also equipped with a venting system, which allows for the safe release of air if the internal pressure exceeds the safe limit.

In summary, the 189-5-5 Johnson Air Capacitor is a reliable and robust electronic component, ideal for power supply applications that require high voltage and fast voltage changes. Its use of air as a dielectric medium ensures safety and longevity, while its low inductance ensures fast response times. The capacitor's cylindrical design and high-quality materials ensure durability and resistance to environmental factors.
