Product Description
CRH1206F27R0P05Z - 27Ω 1206 High Power Thick Film Chip Resistor
Built for circuits where general-purpose 1206 chip resistors would run hot, the CRH1206F27R0P05Z is a 27Ω 0.5W high power thick film chip resistor from EVER OHMS (Tian Er Technology). This CRH-series device doubles the rated dissipation to 0.5W at 70℃ compared to standard 0.25W parts, allowing designers to maintain a compact 3.2mm × 1.6mm footprint while meeting power requirements for current-limiting, voltage-divider, and power-sensing applications.

Material Construction
Layered Material System
| Layer | Material | Function |
|---|---|---|
| Substrate | 96% alumina ceramic (Al2O3) | Provides rigid, thermally conductive base for heat dissipation |
| Resistive film | Ruthenium oxide (RuO2) thick film | Sets nominal 27Ω value with low, repeatable temperature coefficient |
| Inner electrode | Silver-palladium (Ag-Pd) conductor | Connects film to termination with low contact resistance |
| Barrier layer | Nickel (Ni) plating | Blocks diffusion during soldering and improves thermal cycling endurance |
| Outer termination | Lead-free matte tin (Sn) | Delivers reliable solderability for lead-free reflow processes |
| Protective coating | Glass passivation + epoxy | Seals film against moisture, contamination and mechanical damage |
Key Features
- Double the power density: 0.5W rated dissipation in standard 1206 footprint, enabling replacement of larger resistors or avoiding derating issues
- ±1% precision: Tight F-grade tolerance delivered by laser-trimmed RuO2 thick film for dependable sensing accuracy
- Stable over temperature: ±100ppm/℃ temperature coefficient minimizes resistance drift for sensitive current-limiting and divider networks
- Robust ceramic construction: 96% alumina substrate with Ni barrier and glass passivation resists thermal cycling, humidity and mechanical stress
- Lead-free and environmentally compliant: Matte tin termination with RoHS and REACH compliance supports lead-free reflow assembly
- Compact and automation-friendly: 3.2mm × 1.6mm 1206 body suits high-density SMT placement and tape-and-reel feeding
Applications
Thanks to its elevated power rating, this 27Ω high power thick film chip resistor is well suited for circuits that exceed general-purpose part capabilities. Typical applications include current-limiting and pre-charge stages in switch-mode power supplies and DC-DC converters, feedback and voltage-divider networks, LED driver current setting, snubber and inrush protection, and industrial control modules. Its stable resistance also makes it practical for power sensing in motor drivers, battery tooling, and consumer electronics where board space is limited but power headroom is critical.
Packaging & Quality Assurance
The CRH1206F27R0P05Z is supplied on 8mm tape-and-reel with 5,000 pieces per reel, ready for automatic SMT pick-and-place. Every production batch undergoes 100% electrical testing for resistance and tolerance, with inspection against EVER OHMS CRH series specifications before shipment. The product meets RoHS and REACH requirements and is available with certificate-of-compliance documentation upon request, providing reliable, repeatable components for volume manufacturing.
