Cylindrical Types,
High-Voltage Mica Capacitors
Types 291, 292, 293, 294 — Cylindrical Case, High-Current and High-Voltage Circuits
Designed for frequencies ranging from 100 kHz to 3 MHz,
Mica Capacitor Types 291, 292, 293 and 294 are well suited
for high-current and high-voltage circuits like radio transmit-
ters. Cast in cylindrical cases, these capacitors are electri-
cally equivalent to MIL-C-5 Styles CM75 through CM93 in
capacitance and current ratings but are far superior in environ-
mental capability, temperature range, physical size, mounting
configuration, and reliability.
