CRB2A4E680JT

CRB2A4E680JT Description

The CRB2A4E680JT from KYOCERA AVX is a compact, surface-mount resistor network designed for high-density PCB applications. This 4-resistor array features isolated 68Ω resistors with a ±5% tolerance and a ±250ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Encased in an 0804 concave package (2.00mm x 1.00mm x 0.50mm), it offers a space-saving footprint while delivering 62.5mW power per element. The device is rated for MSL 1 (unlimited) moisture sensitivity, making it suitable for extended storage and handling. Though marked as obsolete, its robust design and REACH compliance ensure reliability for legacy or low-volume production.
