r Industry’s widest range of precision chip resistors!
r Tolerance to ±0.01%, TCR to 5 ppm/°C
r Wattage rating up to 1W
RCD’s BLU-CHIP resistors feature top performance at
an economical price!
r Non-standard values available on custom basis
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 stability levels, low noise and voltage
coefficient, as well as low inductance and capacitance. Numer-
ous values available from stock. Consult factory for availability
of non-standard values.
CUSTOM OPTIONS
r Option P: Pulse resistant design
r Option M: Matched sets
r Option ER: Burn-In for Hi-Rel applications
r Option W: Lead-free terminations
r Option A: Marking of resis. code (3 or 4 digits). Opt. A isn’t
available on BLU0201 or BLU0402.
