“BLU-CHIP” Series offers unparalleled performance!
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 unsurpassed stability levels, extremely low
noise and voltage coefficient, as well as low inductance and
capacitance. Consult factory for availability of non-standard values.
EIA E-96 and E-24 values are standard in most sizes.
