Product Description

/ PRECISION WIREWOUND RESISTORS (R Series) /
 

World's widest range! 0.005Ω ~2MΩ, ±0.005% ~10%, 0.5W ~50W. Low cost, available from stock.


/ 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
Radial leads (opt.R), low thermal emf (opt.E), matched sets, custom marking, cut & form, Hi-Rel screening, non-standard values, high- voltage, etc.

Series R 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 silicone 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).

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.


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 constructions are available for even lower inductance levels (Opt.75 inductance= 50% of Opt.X, Opt.76=33%).
