Tektronix High Voltage Capacitor.
Ceramic 500 pf 20KV.
With mounting hardware.
Tektronix part number: 283-0096-00.
This Capacitor is NEW.
(Stock #: TEKCAP02)
Small-type metalling polypropylene capacitor has several strong points,such as the equivalent series impedance is low,the high-frequence charaeter is fine,and the dielectric loss is low.It's mature is steady and trustworthy.They are widely applied to DC.AC and impulse current of the electric apparatus.
In the series of this capacitor-group,tht epoxy resin is adopted as the material of whole patting.It possesses the minor overall dimensions,light weight,high voltage-grade,and excellent insulation.(The insulated voltage is more than 20kw between the outermost shell and the lelctrode.)The function ef the capacitor-group is steady and trusty.

Plastic Capacitors Inc DC filter capacitor, part # LK 200-104, rated at 20kVDC, .1 uF. Previously used. Approximate dimensions: 4 x 2.5 x 7.5 inches.
These products are mainly applied to the vacuum tube high-frequence induction heating apparatus abore 30KM ,and are used as the anode partition direct condenser,the bypass capacitor and the feedback capacitance in the superaudio and the welding equipments.
It's dielectric properties are better,ghe natural induciance is minor,the high-frequence dielectric loss is low,the absorption coefficient is small,and the overload capacity is strong. High voltage power capacitor units include a wide range of one and three-phase all film power and surge protection capacitors. Featuring the most modern technology, they are produced to meet the requirements of different climatic and operating conditions. They can be open or enclosed, high or low power, fixed power , integrated or for use with individual motors.
