PowrFilm resistors offer a

major advantage over com-

parable metal film, carbon

composition and fiberglass

core wire types: A high power-

to-size ratio. The PF1 can dis-

sipate 1.0 watt in a size com-

parable to a 0.25 watt resistor

and 3 watts in a package

smaller than a comparable 1

watt unit.

PowrFilm is a high qual-

ity resistor constructed with a

metal film alloy deposited on

a high grade ceramic body. A

non-flammable coating pro-

vides for environmental and

electrical protection.

PowrFilm resistors are

an excellent choice for large

volume, cost-sensitive applica-

tions requiring a high quality

resistor that approaches the

initial accuracy and long term

stability of wirewound resis-

tors.

FEATURES

• High power-to-size ratio.

• Economical.

• Endures continuous full loading

with very little change in value

over time.

• Excellent resistors where com-

pact, space saving resistors are

required.

• 24 Values per decade.

• RoHS compliant product avail-

able Jan. 2006 Add “E” suffix to

part number to specify.
