Frequently Asked Questions
What resistance value, tolerance, and power rating does the CRCW1206121RFKEA offer?
The Vishay CRCW1206121RFKEA provides 121 Ohm resistance with 1% tolerance and a 0.25 W power rating in a 1206 SMT package measuring 3.2 mm x 0.55 mm. Its 200 V rated AC voltage broadens its applicability to precision voltage dividers and feedback circuits in power supplies and industrial control systems requiring tight resistance accuracy.
When would a designer select the 1206 package CRCW1206121RFKEA over a smaller 0603 resistor for a voltage divider?
The 1206 package of CRCW1206121RFKEA provides 0.25 W power handling versus 0.1 W for a typical 0603 resistor, making it preferable when the voltage divider operates at higher supply voltages (up to 200 V AC rated) or when thermal management requires spreading heat over the larger 3.2 mm body. Its 1% tolerance also makes it suitable for precision feedback networks where component heating must not shift the divider ratio significantly.
How does the 1% tolerance of CRCW1206121RFKEA improve gain accuracy in an op-amp feedback network?
In a non-inverting op-amp amplifier with a 121 Ohm feedback resistor and 1% tolerance, the gain error introduced by this component alone is limited to ±1.21 Ohm worst case, constraining closed-loop gain error to less than ±1% from resistor mismatch alone. Compared to a 5% tolerance resistor, the 1% CRCW1206121RFKEA reduces resistor-induced gain uncertainty by 5x, improving output accuracy in data acquisition, sensor signal conditioning, and precision industrial measurement circuits.
