RCD 160F

10KΩ 5%

100 SERIES

RoHS

Series 100 resistors offer exceptional performance at an economical cost.

Superior stability results from welded construction and windings of premium

grade resistance wire on thermally conductive ceramic cores. Hi-temp sili-

cone coating provides excellent protection & solvent resistance. Tin (or SnPb)

coated copper/copperweld leads ensure proper solderabilty and extended

shelf life. Marked with resis.value & tol. as minimum (custom marking avail).

(Term.W) (Term.Q)

World’s widest range! 0.005Ω ~2MΩ, ±0.005% ~10%, 0.5W ~50W.

Low cost, available from stock & exclusive SWIFT^TMdelivery program.

OPTIONS

 Option X: Low Inductance

 Option P: Increased Pulse Capability

 Option F: Flameproof Coating UL94V-0

 Option ER: 100-Hour Burn-In

 Option B: Increased Power

PULSE CAPABILITY: Excellent pulse ability is inherent with the all-welded

wirewound construction, but can be enhanced by a factor of 50% or more

via special Option P processing (up to 500 joules). Pulse capability is highly

dependent on pulse duration, repetition rate & resis. value, consult factory.

 Radial leads (opt.R), low thermal emf (opt.E), matched sets, custom

marking, cut & form, Hi-Rel screening, non-standard values, high-

voltage, etc. Customized components are RCD’s speciality!

INDUCTANCE: small sizes have inductance of 1- 50uH typ. Larger sizes

and higher values typically have greater levels. For non-inductive design,

specify Opt. X. The max. series inductance for Opt.X resistors at 0.5MHz is

listed in table (per MIL-R-39007). Specialty
