Frequently Asked Questions

What tolerance and temperature coefficient does the CPF0603B91RE precision resistor provide?

The CPF0603B91RE offers ±0.1% resistance tolerance and a low temperature coefficient of ±25 ppm/°C, ensuring that the 91 ohm value drifts by no more than 2.275 ohm over a 100°C temperature range. This level of precision is essential for gain-setting networks, voltage reference dividers, and sensor bridge circuits where resistance drift directly impacts measurement accuracy.

What power rating and package size does the CPF0603B91RE use?

The CPF0603B91RE is rated at 0.063 W in a standard 0603 surface mount package measuring 1.55 mm in length and 0.45 mm in height. Although this is lower than a general-purpose 0.1 W thick film 0603 resistor, the thin film construction achieves ±0.1% precision that standard thick film devices cannot match, making it the preferred choice for precision analog measurement and reference circuits.

In which precision circuit applications does CPF0603B91RE outperform standard thick film 0603 resistors?

The CPF0603B91RE outperforms standard thick film resistors in instrumentation amplifier gain networks, analog filter tuning, and sensor bridge balance circuits where ±1% or ±5% tolerances cause unacceptable gain error. Its ±0.1% thin film precision and ±25 ppm/°C TCR keep the 91 ohm value stable across an operating range of -55°C to 155°C, meeting requirements for medical, aerospace, and industrial high-accuracy measurement equipment.
