MRS7K5BF

MRS7K5BF Description

The MRS7K5BF from TE Connectivity Passive Product is a high-precision 4-resistor network designed for demanding surface-mount applications. Housed in a compact 1206 (3216 Metric) convex package with long-side terminals, it offers a 7.5kΩ resistance per element with an ultra-tight ±0.1% tolerance and a low ±25ppm/°C temperature coefficient (TCR). This RoHS3-compliant and REACH-unaffected component is ideal for precision analog circuits, particularly where TCR matching is critical. Despite its obsolete status, it remains a reliable choice for legacy designs requiring stable performance in voltage divider and signal conditioning applications.
