Type LQ capacitors are designed for DC application such as filtering, bypass and coupling
application. Type LQ capacitors are offered with internal construction variations designed to meet
various circuit conditions. The following suffix letters identify these constructions.
Suffix "V" is extended foil (non-inductively wound), providing soldered contacts thruout. These
capacitors are useful when used as a filter in a power supply which has a very low current output, or
if the capacitor must supply high surge currents. They are oil impregnated, and epoxy filled.
Suffix "Y" is the standard inserted tab construction for filter and bypass
applications and are oil impregnated, and epoxy filled.
The Case is a black phenolic shell. The epoxy end fill is heat resistant and
provides a positive seal to the phenolic shell.
Impregnant used for suffix types "V" and "Y" is a highly refined, purified and
inhibited combination of natural mineral oil and a synthetic oil, the flash point is
greater than 145ºC when measured per method 110.3.4 of specification VV-L-
791.
Mounting Position all types LQ capacitors will operate satisfactorily in any
mounting position.
Terminals are Copperweld leads. The wire gauge and length used are functions
of the case size; minimum of 1-3/4 inch length, #20 or #22 wire.
AC Applications the phenolic shell is a useful housing for low cost alternating
current applications. By the judicious use f available low loss dielectrics, the
frequency range can be extended to 30 megahertz. Call us at (773) 489-2233 or

Temperature Range -20°C to 65°C with nameplate voltage applied.
Test Voltage Terminal to terminal is 150% rated voltage for one minute without a
permanent breakdown.
Capacitance Tolerance Standard capacitance tolerance is ±10%. Standard
tolerances not marked.
Life type LQ capacitors are designed for continuous operation at 65°C for 10,000 hours.
Dielectric Resistance is given in the "R vs. T" graph. Measurement can be made with nameplate voltage. Capacitance
values under 1 mfd. need not exceed two times the graph value per mfd. at any temperature.
Humidity Resistance Test will meet requirements of EIA RS 164.
