AudioCap Metalized High Voltage Capacitor PPMT
The PPMT AudioCap capacitors are metalized polypropylene, available in
voltages high enough to be ideal for all high-voltage applications,
such as power supplies for tube electronics, high-voltage bypassing,
high-voltage coupling and electrostatic loudspeaker crossovers. They
exhibit excellent electrical and environmental characteristics, and
will provide high quality performance and long life at a reasonable
price. The gold-plated OFHC leads provide long-term high reliability,
superior to silver wires, owing to gold�s non-oxidizing properties.

Sizes are accurate to +/- .06. Lead Diameters: .025�
for caps up to 1/2� diameter; .032� for caps up to 3/4� diameter; .04�
for caps 1� and over diameter.
Higher voltages can be obtained by placing these capacitors in
series. Higher capacitance can be obtained by placing these capacitors
in parallel.
Capacitors are not covered by our warranty if they are used at over the
rated voltage and temperatures. Please allow 48 hours break in before
judging sonic performance.
