RBC Capacitors for HID Lighting Purpose Applications

Metallized film capacitors are unsurpassed in terms of size, weight, performance, and reliability for AC
applications. RBC - Capcom brings over 60 years of capacitor manufacturing experience to the product
lines described in this publication. These capacitors represent the best in product design for long-term
reliability and safe operation. RBC’s materials, product, and process development work continue to
provide capacitor users with outstanding total value.

The Gem III HID Lighting Capacitors are designed specifically for HID Lighting applications where the
capacitors are used as part of the ballast circuit for mercury vapor, metal halide, and high-pressure
sodium lamps. The units are designed to operate at temperatures up to 90˚C, which is the normal
requirement for HID ballast capacitors. Due to advances in material technology and breakthroughs in
proprietary capacitor manufacturing processes, selected ratings are now available for operation up to
100°C for 60,000 hours.

GEM III Construction

RBC ‘s Gem III capacitor

s are manufactured with high

-

grade

metallized polypropylene film. This film is in the range of 5 to
10 microns thick, depending on the application voltage and
conditions. The metallized electrode is several hundred
angstroms thick.

The film is wound into capacitor rolls on high-speed, high­precision machines. The winding is extremely tight so that
there is not enough space between the layers for corona
(localized partial electrical discharges) to occur. The rolls are
sprayed on both ends with metal to make connection to the
extremely thin edges of the metalized electrodes. This
process is critical to the quality and performance of the
capacitors.

The rolls are assembled in metal cases, RBC’s proprietary
Dielektrol VI liquid is introduced under vacuum, and the
capacitors are sealed. They are then subjected to 100%
electrical testing for capacitance, dissipation factor, and high
potential electrical withstand, both terminal-to-terminal and
terminal-to-case.

Pressure Sensitive Interrupter

All the capacitors listed in this publication contain
RBC's Pressure Sensitive Interrupter (PSI). This
device, developed by RBC, is designed to sense the
build-up of pressure within the capacitor if a fault
occurs and to interrupt the internal electrical
connections before the case can rupture.

The PSI carries U.L. * recognition for applications
where the specified fault currents are not exceeded.
The fault current is the maximum current that is
available from the circuit to flow through the capacitor
if the capacitor were to become a short circuit with
zero impedance. It is the responsibility of the

capacitor user to determine what the available
fault current is for a particular application.

In the Catalog Number listings a four character U.L.
Code, Pxxx, is given. This number is part of the listing
for RBC in U.L. File No. E7793. When applying to U.L.
for approvals or recognition of equipment using these
capacitors refer to the Pxxx number and not the
Catalog Number of the capacitor in question.

Proper operation of the PSI requires that the cover be
able to expand without restriction. The following
mounting considerations should be noted in mounting

Vertical Clearance

There must be sufficient clearance
between the tops of the terminals (and/or
the assembled wire connectors) and a
plane perpendicular to the capacitor
terminals. This clearance must be at least

0.5 inches plus the electrical spacing

In certain instances capacitors are mounted
with the top of the capacitor case resting
against the chassis and the terminals
protruding through the chassis. Care must
be taken to see that the cutout in the
chassis is large enough. The following
dimensions are recommended.
