ꢀ Standard tolerance is ±1%; 0.1% available
ꢀ Significant space savings over axial lead resistors
ꢀ Available on Tape & Reel
New SM model
ꢀ Economically priced
ꢀ Precision quality, excellent stability, low inductance
Space-saving megohm resistors!
RCD Series BC resistors are designed for precision high-
megohm requirements where space is at a premium.
Operating temperature range is -55°C to +175°C. Type
BC632 features the smallest body size. Type BC630
features an increased voltage rating, wider resistance range,
and the lowest cost. BC633 features two resistors within
single package. Units are epoxy encapsulated for superior
environmental protection.
OPTIONS
ꢀ Option P: increased pulse capability
ꢀ Option H: increased voltage rating
ꢀ Option G: gullwing SM lead forming (avail. on 24mm T&R)
ꢀ Option EQ: 24 hour burn in (or ER -100 hour burn in)
ꢀ Numerous additional options available including custom
marking, matched sets, military screening, etc.
