RCD

Type

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 stand-

offs are helpful in preventing heat transfer to PCB.
