CRB3A4E271JT

CRB3A4E271JT Description

The CRB3A4E271JT from KYOCERA AVX is a high-performance, surface-mount resistor network designed for precision applications. This 4-resistor array features a compact 1206 (3216 Metric) concave package with long-side terminals, offering a resistance value of 270Ω per element at a tight tolerance of ±5%. With a ±250ppm/°C temperature coefficient, it ensures stable performance across varying thermal conditions. The isolated circuit configuration allows independent resistor operation, making it ideal for signal conditioning and voltage division. Rated for 62.5mW power per element, it balances power handling with a low-profile design (0.028" max height), suitable for space-constrained PCBs.
