OPTIONS

Option X: Low Inductance

Option P: Increased Pulse Capability

Option F: Flameproof Coating

Option ER: 100-Hour Burn-In

Option B: Increased Power

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

marking, cut &formed leads, hi-rel screening, non-standard values,

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

DERATING

(derate W/V/A ratings when ambient temp. exceeds 25°C):

Char. U is the max. power for ±0.5% typ. load life stability & 275°C

hotspot, Char. V is max. power for ±3% stability & 350°C hotspot

% RATED POWER

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 coating provides excellent environmental protection and solvent

resistance. Tin (or SnPb) coated copper or copperweld leads offer

excellent solderabilty and extended shelf life.

PULSE CAPABILITY:

Excellent pulse capability results from wirewound

construction. The pulse/overload capability can often be economically

enhanced by a factor of 50% or more via special Option P processing.

Pulse capability is highly dependent on size and resistance value, consult

factory (available up to 500 joules).

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
