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.
