CRH1206FR820P05Z 1206 0.82R 0.5W Current Sense Resistor: Technical Overview and Selection Guide
The CRH1206FR820P05Z is a high-power thick film chip resistor from EVER OHMS' CRH series, designed for precision current sensing in power management and motor control circuits. It combines a low resistance value of 0.82Ω (820mΩ) with ±1% tolerance and a power rating of 0.5W within a standard 1206 footprint (3.2mm × 1.6mm), achieving an elevated power-to-size ratio suitable for space-constrained PCB layouts.
Key Specifications
The resistor operates over a wide temperature range of -55°C to +155°C, with a temperature coefficient of ±600ppm/°C. Its construction utilizes a high-density ceramic substrate with a vacuum-sputtered resistive film and multilayer plated terminals, ensuring solderability and long-term reliability. The product complies with RoHS and REACH directives and is compatible with automated SMT assembly processes.
Application Profile
Typical applications include current sensing in DC-DC converters, battery protection circuits, motor drive feedback loops, and industrial control boards. The 0.82Ω value provides a measurable voltage drop across the resistor for ADC-based current monitoring, while the ±1% tolerance supports consistent measurement accuracy across production units. Designers should account for the ±600ppm/°C temperature coefficient when the application demands high measurement precision over wide thermal excursions, and consider circuit-level compensation where necessary.
