CRH2512F20R0E04Z Ever Ohms 2512 20R 2W High‑Power Thick‑Film Chip Resistor
1. Product Series Overview
CRH2512F20R0E04Z is a high‑power thick‑film chip resistor from Ever Ohms CRH series. It comes in standard 2512 SMD package with nominal resistance of 20R (20Ω) and power rating of 2W. As an upgraded power‑type thick‑film resistor, it solves the power‑limit issue of conventional 2512 chip resistors, widely used for current limiting, voltage dividing and discharge loads in power‑related circuits.
The CRH series is Ever Ohms high‑power product line. Optimized alumina ceramic substrate improves heat dissipation, delivering higher power rating without changing PCB footprint, balancing SMT compatibility and power‑handling capability for mass automated assembly.

4. Key Product Features
- High power density: 2W power rating within 2512 footprint, double the power of standard 1W 2512 resistors. Eliminates multi‑resistor parallel design and saves PCB layout space.
- Stable resistance performance: ±1% tolerance together with ±100 ppm/℃ TCR ensures limited resistance shift under temperature variation, suitable for medium‑precision power circuits.
- Superior environmental reliability: Alumina ceramic base provides good thermal conductivity. Resists thermal shock, temperature cycling and damp‑heat load, keeping resistance drift low for long‑term operation and reducing field failure rate.
- Mass‑production friendly: Standard 2512 tape‑and‑reel form factor fits mainstream SMT lines. Soldering profile is compatible with general chip resistors without production adjustment.
- Cost‑effective solution: Thick‑film technology delivers better cost performance compared with thin‑film and metal‑alloy power resistors, ideal for high‑volume industrial and power‑supply projects.
- Full compliance: RoHS, halogen‑free and lead‑free requirements are satisfied for global market shipments.
