CRH1206FR750P05Z 1206 0.75R 0.5W Current Sense Resistor: Specifications and Selection Guide

The CRH1206FR750P05Z is a thick-film high-power current sense resistor manufactured by EVER OHMS. It comes in a standard 1206 surface-mount package with a nominal resistance of 0.75Ω (750mΩ), ±1% tolerance, and a rated power of 0.5W. Within the compact 1206 footprint (3.2mm × 1.6mm), this part achieves a power density that suits current-sampling circuits where board space and power dissipation are both constrained.

Key Specifications and Construction

The ±1% resistance tolerance is directly relevant to current sense applications, where the resistor converts load current into a millivolt-level voltage for downstream comparators or ADCs. The temperature coefficient is typically ±600ppm/°C across an operating range of -55°C to +155°C. The thick-film construction—metal oxide paste screen-printed onto an alumina substrate and sintered at high temperature—provides reasonable resilience against pulse current transients. The termination is lead-free (indicated by the “Z” suffix), and the part complies with RoHS and REACH directives.

Typical Applications

The 1206 0.75R current sense resistor is commonly found in three areas. In power management, it serves as a feedback or overcurrent-protection element in switch-mode power supplies and DC-DC converters, where the 0.75Ω value keeps sensing-path losses low. In battery management systems (BMS) and motor drive modules, it enables real-time current monitoring for charge/discharge or winding current. In automotive electronics, it is used for current sampling in engine control units (ECUs) and on-board chargers (OBCs), where the wide temperature range supports reliable operation in high-temperature, vibration-prone environments. Industrial PLC modules, servo drives, and medical monitoring equipment also employ this specification in signal-conditioning stages.

Sourcing

The CRH1206FR750P05Z is an EVER OHMS original product. Sourcing through authorized channels is recommended to ensure authenticity and technical support. Shenzhen Shunhai Technology Co., Ltd. has been an authorized Tier-1 distributor for EVER OHMS in mainland China since 2017, holding a current annual certificate and offering FAE-level selection and design support.
