CRH1206FR270P05Z 1206 0.27R 0.5W Resistor Overview

1. Part Number Breakdown

The CRH1206FR270P05Z is a high-power thick film chip resistor from EVER OHMS (Tian Er Technology), belonging to the CRH series. The part number decodes as follows: CRH designates the high-power thick film series; 1206 indicates the package size (3216 metric); F represents ±1% resistance tolerance; R270 denotes 0.27Ω (270mR); and P05Z is the packaging and specification code indicating a 0.5W power rating.

2. Key Specifications

This 1206 0.27R 0.5W resistor features a resistance of 0.27Ω with ±1% tolerance, a rated power of 1/2W (0.5W), a temperature coefficient of ±600PPM/°C, and an operating temperature range from -55°C to +155°C. The product complies with EU RoHS Directive (2011/65/EU) and REACH regulations. Its power rating is twice that of a standard 1206 chip resistor (typically 0.25W), delivering higher power handling capability within the same PCB footprint.

3. Technical Highlights

The CRH series achieves its 0.5W rating in the 1206 package through several process optimizations: adjustments to the thick film paste formulation improve heat resistance of the resistive layer; enhanced ceramic substrate thermal conduction reduces localized hot spots; and improved electrode processing strengthens terminal-to-substrate bonding for long-term load reliability. These combined improvements significantly raise power density within the standard 1206 footprint, making the resistor well-suited for space-constrained and thermally challenging designs.

4. Typical Applications

The low 0.27Ω resistance makes this component naturally suited for current sensing. In DC-DC converters, battery management systems (BMS), motor drive circuits, and LED driver power supplies, the CRH1206FR270P05Z is commonly used as a current sense resistor, converting circuit current into a voltage signal readable by the controller. The 0.5W power margin also helps absorb inrush current surges during startup, with established use in switching power supply feedback loops, power management modules, and industrial control boards.
