Frequently Asked Questions
What is the power rating of the WCR1206-220KFI and how does this affect its use in continuous-duty circuits?
The WCR1206-220KFI is rated at 0.25 W continuous power dissipation in the 1206 package. For circuits where the resistor must sustain steady current, designers should ensure the applied voltage across the 220 kΩ resistance stays below approximately 235 V to avoid exceeding this thermal limit.
How does the 1% tolerance of the WCR1206-220KFI benefit precision analog designs compared to a 5% resistor?
With 1% tolerance, the WCR1206-220KFI limits resistance deviation to ±2.2 kΩ around the 220 kΩ nominal value, versus ±11 kΩ for a 5% part. This tighter spread reduces gain errors in amplifier feedback networks and improves voltage divider accuracy to within 1%, directly benefiting ADC reference circuits and sensor bias networks.
When should an engineer select the 1206 package size for the WCR1206-220KFI instead of a smaller 0402 or 0603 resistor?
The 1206 package (3.2 mm x 1.6 mm) is preferred when the 0.25 W power rating is needed, as 0402 and 0603 packages typically handle only 0.063 W and 0.1 W respectively. It also provides easier manual soldering during prototyping and better mechanical robustness for high-vibration industrial or automotive PCB assemblies.
