( Brand: Jennings ), ( Manufacturer Part Number: VC12-20 ), ( Part Type: Radio Vacuum Capacitor Plate ), ( Country/region Of Manufacture: United States )
The Jennings VC12-20 radio vacuum capacitor is a high-performance component designed for use in vintage radio and electronic equipment. This capacitor boasts a capacitance value of 12 picofarads (pF) and a voltage rating of 20,000 volts (kV), making it suitable for applications requiring both high capacitance and high voltage.
The VC12-20 capacitor features copper plates, which are coated with a layer of silver for enhanced conductivity. The silver coating reduces electrical resistance, allowing for faster charge and discharge times and improved overall performance. The copper plates are housed within a vacuum-sealed glass enclosure, which helps to maintain the capacitor's high voltage rating and prevent the degradation of the silver coating over time.
The vacuum-sealed design also helps to reduce the risk of electrical arcing, which can occur in capacitors with air gaps between the plates. This can help to ensure the longevity of the capacitor and prevent damage to other components in the circuit.
In addition to its high voltage and capacitance ratings, the Jennings VC12-20 capacitor is also renowned for its reliability and durability. The copper plates and vacuum-sealed glass enclosure are both resistant to corrosion and wear, ensuring that the capacitor can withstand the rigors of use in vintage radio equipment.
Overall, the Jennings VC12-20 radio vacuum capacitor is an excellent choice for anyone looking to restore or maintain their vintage radio or electronic equipment. Its high voltage and capacitance ratings, combined with its durable construction and reliable performance, make it an essential component for any vintage electronics enthusiast.
