FGRA FIBER GLASS RESISTOR ASSEMBLIES

Download PDF File

The FGRA series of high power, fiber glass resistors are designed for use in high power inverters.  The basis
for these models are wire wound elements with a fiber glass core.  These are covered by a case which
conforms to international safety specifications.  This case is powder coated and baked for durability.
