Frequently Asked Questions

For a precision current-sensing circuit, how does the CPF0603B18RE's ±25 ppm/°C TCR affect measurement accuracy over an industrial temperature range?

Over an industrial temperature span of -40°C to +125°C, a ±25 ppm/°C TCR on an 18 Ω resistor produces less than 0.41% total resistance drift, maintaining measurement accuracy far tighter than ±1% thick-film alternatives, making it suitable for medical instruments, precision ADC front-ends, and calibrated current references.

What power dissipation can CPF0603B18RE handle, and how does it fit high-density PCB layouts?

Rated at 0.063 W (63 mW) in the compact 0603 SMD package, the CPF0603B18RE handles typical low-power precision circuit loads without thermal derating. Its 1.55 mm × 0.8 mm footprint fits standard 0603 land patterns, enabling placement beside sensitive amplifier or ADC inputs in high-density PCB designs.

Why would a medical device designer choose CPF0603B18RE over a standard 18 Ω thick-film resistor for long-term calibration stability?

Medical devices demand stable analog readings over their service life; the CPF0603B18RE's ±0.1% tolerance and ±25 ppm/°C TCR prevent calibration drift that a ±5% or ±100 ppm/°C thick-film 18 Ω resistor would introduce over the full device range of -40°C to +85°C, improving measurement reliability and patient safety.
