Frequently Asked Questions

How does the ±25 ppm/°C TCR of CPF0603B5K1E affect resistance stability in precision analog circuits?

With a ±25 ppm/°C temperature coefficient, the CPF0603B5K1E 5.1 kΩ resistor stays stable across its full -55°C to 155°C operating range, keeping voltage divider and op-amp feedback ratios accurate to within 0.0025% per degree—essential for precision instrumentation and sensor signal conditioning.

When should designers choose the ±0.1% tolerance of CPF0603B5K1E over a standard 1% resistor?

Precision circuits such as Wheatstone bridge sensors, DAC attenuators, and op-amp feedback paths require the ±0.1% tolerance of CPF0603B5K1E to minimize gain error. Standard 1% resistors introduce up to 10× more resistance deviation across the 5.1 kΩ value, degrading measurement accuracy in tightly calibrated analog designs.

What power level does CPF0603B5K1E handle and what current does that allow through the 5.1 kΩ resistance?

The CPF0603B5K1E is rated at 0.063 W (63 mW) maximum in its 0603 SMT package, which allows a continuous current of approximately 3.5 mA through its 5.1 kΩ resistance—sufficient for most low-power precision signal-path, voltage reference divider, and analog conditioning applications.
