745C101151JTR

745C101151JTR Description

The 745C101151JTR from CTS Resistor Products is an 8-resistor bussed network array designed for high-density PCB applications. Housed in a compact 2512 (6432 Metric) concave long-side terminal package, it offers a resistance value of 150Ω per element with a ±5% tolerance and a ±250ppm/°C temperature coefficient. With a power rating of 63mW per resistor and a low-profile 0.028" (0.70mm) seated height, this surface-mount device (SMD) is optimized for space-constrained designs. The ROHS3-compliant and REACH-unaffected construction ensures environmental compliance, while its MSL 1 (Unlimited) rating guarantees reliability in humid conditions.
