New SM model
Space-saving megohm resistors!
RCD Series BC resistors are designed for precision high-
megohm requirements where space is at a premium. Operat-
ing 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 environ-
mental 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.
