Characteristics -
Environmental and Mechanical
This range of Power Wirewound
Resistors are wound on continuous
glass fibre elements or have a ceramic
core depending on resistance 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 sup-
plies and triac based speed controls.
Custom Design Variants in value and
style are welcomed.

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.
One Lead Length 20mm longer than case length. Supplied with one longer lead wrapped back in flute in ceramic.
