CRH1206F1R10P05S 1206 1.1R 0.5W Low-TCR High Power Resistor
Product Overview
The CRH1206F1R10P05S is a high-power thick film chip resistor from Ever Ohms Technology (TA-I Technology), part of the CRH series. Ever Ohms was founded in 1988 and is headquartered in Taiwan, specializing in the development and manufacturing of chip resistors and resistor arrays. The company holds ISO9001, IATF 16949, and AEC-Q200 certifications, serving customers across industrial control, automotive electronics, communication equipment, and consumer electronics.
This resistor features a 1206 package (3.2mm × 1.6mm), a nominal resistance of 1.1Ω, ±1% tolerance, a rated power of 0.5W, and a temperature coefficient of ±100 ppm/°C. Compared with conventional 1206 thick film resistors typically rated at 0.25W, the CRH1206F1R10P05S doubles the power handling capability within the same PCB footprint.
Part Number Decoding
| Field | Meaning |
|---|---|
| CRH | Ever Ohms high-power thick film chip resistor series |
| 1206 | EIA imperial package size, approximately 3.2mm × 1.6mm |
| F | ±1% resistance tolerance |
| 1R10 | Nominal resistance 1.1Ω, with R as decimal placeholder |
| P05 | Rated power 0.5W (1/2W) |
| S | Packaging code |
The “P05” suffix is the critical identifier that distinguishes this part from standard 1206 thick film resistors. The full part number CRH1206F1R10P05S should be specified in the BOM to avoid accidentally substituting a 0.25W rated component.
Key Electrical Specifications
| Parameter | Value |
|---|---|
| Manufacturer | Ever Ohms Technology (TA-I Technology) |
| Series | CRH High Power Thick Film |
| Package | 1206 (3.2mm × 1.6mm) |
| Resistance | 1.1Ω (1R10) |
| Tolerance | ±1% (F grade) |
| Rated Power | 0.5W at 70°C ambient |
| TCR | ±100 ppm/°C |
| Max Working Voltage | 200V |
| Max Overload Voltage | 400V (5s) |

The 0.5W rating is specified at 70°C ambient; derating applies linearly above this temperature, reaching zero at 155°C. A power margin of 20%–30% is recommended for long-term reliability.
Technical Highlights
The CRH1206F1R10P05S achieves 0.5W power handling in a standard 1206 package through three key process improvements: a high thermal conductivity alumina substrate that efficiently transfers heat to the PCB copper, an optimized resistor paste formulation that maintains ±100 ppm/°C TCR across the full operating temperature range, and a multilayer terminal electrode structure that ensures uniform current distribution.
