CUSTOM OPTIONS
RCD’s expertise in the field of ultra-precision resistors since 1973,
combined with the latest in automated chip resistor production
equipment, enables precision chip resistors at prices comparable to
lower grade devices. The BLU-chip design features excellent stabil-
ity levels. Intermediate and extended-range values are available on
custom basis. Popular values are available from stock.
Option P: Pulse resistant design
Option ER: Burn-In for Hi-Rel applications
Option V: +200° operating temperature
Option A: Marking of resis. code in 3 or 4 digits
(not available on BLU0201 or BLU0402)
Matched sets and TC’s to 2ppm available (limited range)
