CRB3A4E100JT

CRB3A4E100JT Description

The CRB3A4E100JT from KYOCERA AVX is a compact, surface-mount resistor network designed for high-density PCB applications. Part of the CRB series, this 4-resistor array features isolated circuits with a 10Ω resistance per element and a tight ±5% tolerance, ensuring reliable performance in precision circuits. Encased in a 1206 (3216 Metric) concave package with long-side terminals, it offers a low-profile height of 0.028" (0.70mm), making it suitable for space-constrained designs. With a 62.5mW power rating per resistor and a ±250ppm/°C temperature coefficient, it balances power handling and stability across operating temperatures. The device is REACH compliant and rated MSL 1 (Unlimited), simplifying storage and handling.
