Type LJ capacitors
represent the best designs for very high voltage circuits. All standard
items are low inductance construction, housed in a rectangular phenolic
case. Type LJ capacitors are designed for high voltage application with
plastic-paper dielectric capacitor elements. Connections are made to the
extended foil sections with medium-heavy wiring allowing large discharge
current. Consult factory for current and repetition rate limits.
Applications include; power supply filters, discharge, pulse forming
networks, bypass, and arc and spark suppression.
Capacitance Tolerance
standard is ±10%, however type LJ capacitors may be ordered with a ±5%
tolerance.
Temperature Range is
-55ºC to 65ºC. No derating of voltage is necessary over this range.

Dielectric Resistance
(parallel resistance) Minimum acceptable resistance is 10,000 megohms
per microfarad or 10,000 megohms. Which is less.

Peak Ripple Voltage
plus the DC voltage must not exceed the nameplate voltage. As a general
rule, the acceptable peak-to-peak ripple voltage (expresses as a percent
of the nameplate voltage) for a given frequency is listed below. This is
not valid at higher voltages and larger capacitance values. An inquiry
should be sent to the factory regarding suitability of the application.

Test Voltage is 150%
of nameplate voltage for two minutes in air at room temperature.

Impregnant
is a highly redefined/purified and inhibited mineral oil with a
flash point greater than 145ºC when measured per method 110.3.4
specification V V-L-791.
Dielectric is a combination of polyester film and Kraft
capacitor tissue. Aluminum foils constitute the plates ad the capacitor
sections have extended foils insuring low I²R losses and low inductance.
Case is fabricated paper-phenolic with flexible side
walls, permitting the case to be completely filled with the impregnant.
This feature provides expansion and contraction of the oil over the
temperature range.
Terminals on type LJ suffix B (for styles B) are ¼-20
brass screws. Other size terminals or threaded inserts may be supplied
on special order.
Mounting Foot has holes for ¼-20 screw
- small bases have 2 holes and large base sizes have 4 holes.
How To Order - Select the part number from the list and
add suffix "-5", if 5% capacitance tolerance is required. For other
styles call (604)925-6150 or
