[Hallicrafters] Self resonant frequencies of various capacitors

[Carl]

Here is a short list of a few new caps I tested as I was suspicious of a 
previous posters results.

Equipment used: Measurements Model 59 GDO, HRO-500, R-7000. The GDO dip was 
at the most distance to get a solid dip which is more than close enough for 
his test.

Lead lengths ranged .5 to 1" depending on physical cap dimensions.

.001 1000V disc 120 MHz
.001 1000V CDE film 25.2 MHz

.01 500V disc 31.8 MHz
.01 630V Illinois film 11.35 MHz
.01 600V Orange Drop 9.1 MHz

.02 600V disc 10.1 MHz
.022 400V Illinois film 8.25 MHz

.03 600V Orange Drop 6.25 MHz

.05 100V disc 6.8 MHz
.05 100V film 5.6 MHz
.047 600V Orange Drop 3.7 MHz

I'll let others calculate the inductance of each cap.

Somewhere I have a few Black Beauties that show almost no leakage, I'll dip 
those when I can find them. There are also a few hundred paper caps, NOS and 
pulls, on hand that I use for restuffing; I'll see how a few dip.
