Superior stability results from welded construction and windings of premium
grade resistance wire on thermally conductive ceramic cores. Hi-temp sili-
delivery program.
TM
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).
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%).
