Frequently Asked Questions
What is the resistance value and tolerance of the CRCW1206680RFKEAHP?
The CRCW1206680RFKEAHP provides a nominal resistance of 680Ω with 1% tolerance (F grade), meaning the actual value is guaranteed between 673.2Ω and 686.8Ω. This level of precision is suitable for accurate voltage divider ratios, pull-up resistor networks, and current-sensing circuits where a 10% resistor would introduce unacceptable gain error in the signal chain.
What power rating and AC voltage rating does CRCW1206680RFKEAHP support in industrial designs?
The CRCW1206680RFKEAHP is rated for 0.25W continuous power dissipation and 200V AC working voltage. The 200V rating allows it to be used directly in mains-voltage sensing dividers on 120VAC or 230VAC supply monitoring circuits, providing a safe margin well above the 170V peak of a 120V RMS line.
How does the 1206 package size of CRCW1206680RFKEAHP benefit high-reliability PCB assembly compared to smaller 0402 or 0603 resistors?
The 1206 package (3.1mm x 1.55mm x 0.5mm) of the CRCW1206680RFKEAHP offers larger solder pad area and greater thermal mass than 0402 or 0603 resistors, which improves solder joint reliability under thermal cycling from -55°C to 155°C. This makes 1206 resistors the preferred choice for industrial and automotive PCBs subject to vibration, shock, and wide temperature swings, where solder fatigue is a primary failure mechanism.
Is CRCW1206680RFKEAHP suitable for precision voltage divider applications in 3.3V microcontroller ADC circuits?
Yes, the CRCW1206680RFKEAHP with 1% tolerance and low temperature coefficient typical of thick-film 1206 resistors is well-suited for voltage divider networks at the ADC input of 3.3V microcontrollers. At 680Ω, it limits leakage current and provides low source impedance for ADC inputs requiring under 10kΩ source resistance, while the 0.25W rating accommodates the divider's continuous dissipation in a 5V supply without thermal derating.
