PW resistors are designed for general purpose and semi-precision
medium power applications. The fireproof ceramic construction
provides excellent thermal conductivity and is resistant to moisture &
solvents. Typical marking is ‘RCD’, value, tol. &wattage (or type).
Resis. element is wirewound on lower values & power film on higher
values, depending on options (e.g. opt. P & T parts are always WW). If
a specific construction is preferred, specify opt.WW or M (not avail. in
all values).
APPLICATION NOTE #1: Resistor Comparison
Series PW resistors offer moderate performance levels at prices
below that of other WW or film technologies. Other choices for
medium power applications are Series PV resistors (2W to 10W,
similar to PW in vertical package); Series 100 military grade WW (1/
2W to 50W, offers improved performance, pulse capability, and
reliability); Series RW (1W to 5W WW, offers space savings); and
Series RSF/RMF power film (1/2W to 9W, offers reduced inductance).
APPLICATION NOTE #2: Temperature Rise
Power resistors reach elevated temperatures (typically 125° to
250°C) when operated at full wattage, so when utilizing above 50%
power rating, the bodies should be mounted off the PCB with
adequate clearance from heat sensitive components. Opt. A standoffs are helpful in preventing heat transfer to PCB.
