PW resistors are designed for general purpose and semi-precision

power applications. The fireproof ceramic construction provides

excellent thermal conductivity and resistance to moisture & solvents.

Typical marking is ‘RCD’, value, tol. &wattage (or type). The resistance

element is wirewound on lower values, & power film on higher values

depending on options (opt. P & T parts are always WW). If a specific

construction is preferred, specify opt.WW or M (not avail. in all values).

ꢀ Low cost and the industry’s broadest selection!

ꢀ Available from stock in popular sizes (5W&10W, 0.1Ω to5K)

and selected values in other sizes; non-stock items are

available on exclusive SWIFT^TMdelivery program

ꢀ Tolerance to ±0.05%, TCR to ±5 ppm/°C

ꢀ Wide resistance range: .05Ω to 1MegΩ

ꢀ Tape & Reel available up to 10W size (Opt.A not avail. on T&R)

OPTIONS

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).

ꢀ Option X: Non-inductive (PW5X & smaller: ≤50Ω =0.2uH max,

>50Ω= 0.37uH max; PW7X & larger: ≤50Ω=0.3uH max,

>50Ω= 0.6uH max). Reduced inductance levels available

ꢀ Option T: Temp. sensitive (up to +6000ppm/°C)

ꢀ Option P: Increased pulse capability

ꢀ Option FF: Fuse within 10S at 30x rated W⁴and within 45S

at 20x rated W (1Ω to 1K). Custom fusing characteristics avail.

ꢀ Option B: Increased power

APPLICATIONNOTE#2:TemperatureRise

ꢀ Option A: Standoffs built into ceramic case

ꢀ Additional options available... burn-in, special marking, non-

standard values, increased voltage, longer or heavier gauge

leads, specialty lead wire material/plating/insulation, cut & formed

leads, etc. Customized components are an RCD specialty!

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.
