High Power Resistor
TYPE SBC (SQUARE CERAMIC) SERIES
This range of Power Wirewound Resistors are wound on
continuous glass fibre elements or have a ceramic core
depending on resistor value. The element is housed in a
ceramic case and sealed with an inorganic silica filler. Their
construction gives a resistor with high insulation resistance
and low surface temperature, capable of withstanding high
overload currents. These resistors are ideally suited to a
variety of applications within industrial and commercial
environments, where performance and reliability are of prime
importance. Applications include fan force ovens, cooker
hoods, power supplies and triac based speed controls.
Custom Design Variants in value and style are welcomed.

CONSTRUCTION
A range of flame-proof wirewound resistors with excellent electrical and mechanical characteristics. The resistance wire is wound on a fibreglass
or ceramic core and protected by a ceramic body. This construction combines good thermal characteristics with high insulation resistance,
and gives good physical protection. Lead length allows vertical or horizontal mounting.

TYPE SBC - SBCH (Axial Power Resistor)
We offer three ceramic profiles for the main wattage sizes. These are for additional heat dissipation and vertical mounting of resistors.
The suffix for each style is as follows:SBC Standard
SBCH 4/5/6/7
SBCH 8/11/15
TYPE SBCHE (For Vertical Mounting)
We offer SBCHE Styles with one lengthened lead for vertical mounting. See additional hardware on last page.
Lead Length 20mm longer than case length. Supplied with one longer lead wrapped back in flute in ceramic.
