4. Key Advantages
- Small case, high power — The CRH series boosts power from the standard 2512 1W to 2W through optimized thick-film materials and multi-layer terminations, saving PCB space and reducing parallel-component needs.
- Stable resistance — ±100ppm/℃ TCR over a -55~+155℃ range ensures consistency in harsh environments.
- Robust reliability — Alumina substrate, ruthenium-based paste, high-temp sintering, and glass-glaze protection provide moisture, anti-sulfuration, and surge resistance.
- Process-compatible — Supports reflow and wave soldering; RoHS-compliant for automated assembly.
- Domestic alternative — Cost-effective, stable supply chain for import substitution.
5. Applications
- Power & Energy: SMPS startup/bleeder resistors — 1KΩ limits inrush current, 2W absorbs startup surges.
- Industrial Control: PLCs, inverters, motor drives (current limiting, voltage dividers).
- Automotive: On-board power, ECUs, LED drivers (select automotive-grade as needed).
- Computing & Comms: Motherboards, routers, base stations (bias/feedback networks).
- Consumer & Appliances: Air conditioners, refrigerators, lighting.
- Instrumentation: Meters, precision dividers.
6. Usage & Selection Tips
- Power derating: Rated at 70℃; follow the derating curve above 70℃.
- Voltage check: Working voltage must not exceed the rated ~200V; use a high-voltage series otherwise.
- Soldering: Reflow peak ≤260℃ per standard profile.
- Alternatives: For higher precision/lower TCR, consider thin-film series; for more power, use parallel parts or a larger case.
