RCD’s BLU-CHIP resistors feature top performance at
an economical price!
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.
