Mounting clip
This saddle clip conforms to
the configuration of Ohmite’s
A Series resistor to provide
secure mounting. Made
of a durable thermoplastic
polyester, the saddle clip is
designed to secure the A
Series in place while safely
withstanding its operat-
ing temperatures. Use (2)
saddle clips per resistor for
extra stability.

The “A” Series non-inductive, ceramic composite
resistors are designed for a variety of applications
where high energy handling capabilities are crucial.
These resistors are ideal for any application which
is subject to surges, high peak power, or impulse
energy.
Their unique design allows uniform distribution
of energy throughout their structure which results
in low thermal stress. The high-temperature,
solvent-resistant epoxy coating carries a UL94V0
flammability rating which is suitable for almost any
environment.
