Frequently Asked Questions
How precise is the CRCW0402105KFKED for use in a 105kΩ voltage divider feedback network?
The CRCW0402105KFKED offers a 1% tolerance on its 105kΩ thick film resistance, which means the actual resistance falls within 103.95kΩ to 106.05kΩ. This level of precision is adequate for most analog feedback and voltage divider networks in microcontroller power management circuits, where small deviations can affect output voltage regulation accuracy within acceptable margins.
Can the CRCW0402105KFKED handle 50V AC signals in signal conditioning circuits?
Yes, the CRCW0402105KFKED is rated for up to 50V AC, making it suitable for signal conditioning stages that interface with higher-voltage analog signals before they reach low-voltage ADC inputs. The 0402 package measures 1 mm x 0.5 mm, and its 0.063W continuous power rating should be verified against the actual current drawn at 50V to ensure derating is respected.
When should a designer choose the CRCW0402105KFKED over a 0603-packaged 105kΩ resistor?
The CRCW0402105KFKED in its 0402 package (1 x 0.5 x 0.35 mm) saves approximately 40% PCB area versus a 0603 resistor at the same 105kΩ, 1% specification, making it the right choice for space-constrained designs such as wearables, miniaturized IoT modules, and mobile devices where every square millimeter of board space matters and power dissipation stays below 63mW.
