Review JOHNSON Ef Air Variable Capacitor Dual 4.5kv

The Johnson 100ED45 EF air capacitor is a high-performance electrical component designed for various applications that require large capacitance and high voltage ratings. This dual capacitor is specifically configured with two capacitors, each having a capacitance of 100 picofarads (pF) and a maximum voltage rating of 4.5 kilovolts (kV).

Each capacitor within the 100ED45 EF unit is constructed using a robust aluminum electrode design, which provides excellent electrical conductivity and reliability. The dielectric medium used in these capacitors is air, which offers several advantages such as low loss, high volumetric efficiency, and a wide temperature operating range.

The 100ED45 EF air capacitor features a compact and streamlined design, with a diameter of approximately 178.5 millimeters (mm) and a height of about 131.2 mm. This compact size makes it an excellent choice for applications where space is at a premium.

The 100ED45 EF capacitor also boasts a low equivalent series resistance (ESR) and equivalent series inductance (ESL), which translates to faster response times and improved power factor performance. The capacitor's temperature coefficient is also well-controlled, ensuring stable capacitance values over a wide range of operating temperatures.

This Johnson air capacitor is designed to meet or exceed the requirements of various industry standards, such as ANSI/IEEE, IEC, and JIS. It is suitable for use in applications such as radio frequency (RF) power supplies, power factor correction circuits, and voltage stabilization systems.

The 100ED45 EF air capacitor is shipped fully tested and insulated with a suitable protective coating. It is recommended that users consult the manufacturer's datasheet and application guidelines for proper installation and maintenance procedures.

The Johnson 100ED45 EF air capacitor is a high voltage capacitor used in various electrical applications, particularly in power systems and radio frequency circuits. like all components, it has its advantages and disadvantages.

1. High Voltage Rating: With a voltage rating of 4.5kV, this capacitor can handle high voltage applications, making it suitable for use in power systems and high voltage circuits.

2. Large Capacitance: With a capacitance of 100pf x 2 (200pf in total), this capacitor can store and discharge large amounts of electrical charge, which is beneficial in applications requiring quick energy storage and release.

3. Air Dielectric: The use of an air dielectric in this capacitor provides several advantages, including good insulating properties, high voltage stability, and low power loss.

4. Rugged Construction: The Johnson 100ED45 EF air capacitor is built with durable materials and features a robust design, making it suitable for use in harsh environments and industrial applications.

1. Large Size and Weight: Due to its high voltage rating and large capacitance, the Johnson 100ED45 EF air capacitor is quite large and heavy, which can make it more difficult and expensive to transport and install.

2. Cost: The cost of this capacitor is relatively high compared to other capacitor types due to its large size, high voltage rating, and use of an air dielectric.

3. Longer Lead Lengths: The longer lead lengths required for this capacitor can increase the risk of electromagnetic interference (EMI) and radio frequency interference (RFI), which can negatively affect the performance of the circuit.

The Johnson 100ED45 EF air capacitor is a high-performance component suitable for applications requiring large capacitance and high voltage handling capabilities. Its advantages include its high voltage rating, large capacitance, air dielectric, and rugged construction. However, its disadvantages include its large size and weight, high cost, and longer lead lengths.

If you require a high voltage capacitor with large capacitance and can accommodate its large size and weight, then the Johnson 100ED45 EF air capacitor may be a good choice for your application. However, if size and weight are a concern, or if you have a lower voltage or smaller capacitance requirement, then you may want to consider alternative capacitor types, such as electrolytic or ceramic capacitors. Ultimately, the decision should be based on the specific requirements of your application and the trade-offs you are willing to make.

Details:

Used and in good shape. No damaged ceramic. I have had several that bought before just for the 4 ceramic insulators to fix other capacitors.
