CRH1206F1R10P05Z 1206 1.1R 0.5W High Power Resistor
Product Overview
The CRH1206F1R10P05Z 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 specializes 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, and communication equipment. The CRH series is Ever Ohms' core thick film product line for high power density circuit designs, covering package sizes from 0402 to 2512 with power ratings from 0.1W to 2W.
This model achieves a 0.5W power rating in a standard 1206 package (3.2mm × 1.6mm), doubling the power handling capability of conventional 1206 thick film resistors typically rated at 0.25W within the same PCB footprint.
Part Number Decoding
| Field | Meaning |
|---|---|
| CRH | High-power thick film chip resistor series |
| 1206 | EIA imperial package size, approx. 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) |
| Z | Halogen-free, tape and reel packaging code |
The “P05” suffix is the critical identifier distinguishing this part from standard 1206 thick film resistors. The full part number should be specified in the BOM to avoid substituting a 0.25W rated component.
Key Electrical Specifications
| Parameter | Value |
|---|---|
| Manufacturer | Ever Ohms Technology |
| Series | CRH High Power Thick Film |
| Package | 1206 (3.2mm × 1.6mm) |
| Resistance | 1.1Ω |
| 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) |
| Operating Temperature | -55°C to +155°C |

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. The ±100 ppm/°C temperature coefficient maintains resistance stability across the full operating temperature range.
Process and Technical Features
The CRH1206F1R10P05Z achieves 0.5W power handling in a standard 1206 package through three key process improvements: a high-purity alumina ceramic substrate (Al₂O₃ ≥96%) that reduces vertical thermal resistance; a ruthenium-based thick film resistive layer with a thickness in the 100μm range for enhanced current-carrying capability; and a three-layer terminal electrode structure (silver/nickel/tin) with a thickened nickel barrier that suppresses silver migration while the lead-free tin plating ensures reliable SMT soldering. A glass protective overcoat provides moisture resistance and chemical durability.
Typical Applications
The combination of 1.1Ω resistance and 0.5W power capacity makes this resistor suitable for current limiting, voltage division, power loading, and low-current sensing. Typical applications include power modules, DC-DC converters, LED drivers, industrial control boards, and home appliance control circuits. As a drop-in replacement for standard 1206 resistors, it resolves localized heating or insufficient power margin issues without PCB layout changes, helping to simplify the BOM and reduce assembly costs.
