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.
