Manufactured using thick film technology on a 96% alumina ceramic substrate. The CRH series' most notable feature is its "power upgrade" design – achieving 2W rated power in the standard 2512 package, approximately 100% higher power density than conventional resistors of the same size (typically 1W). This breakthrough comes from optimized ceramic substrate thermal paths, improved resistive paste formulations, and enhanced electrode heat dissipation structures.
The ±100ppm/℃ TCR combined with a -55℃ to +155℃ operating range ensures stable resistance values under harsh conditions. The product is ISO-9001, ISO-TS16949 certified and compliant with AEC-Q200 automotive electronics standards.
3. Applications
With 806kΩ resistance and 2W power handling capability, CRH2512F806KE04Z finds use in:
Power Management – startup resistors in switching power supplies, RC snubber circuits, high-voltage bleed resistors.
Industrial Control & Measurement – load resistors in PLC circuits, standard loads in ATE systems, precision voltage dividers in meters and navigation equipment.
Automotive Electronics – BMS battery balancing circuits, engine control units, leveraging AEC-Q200 certification.
Consumer Electronics & Communications – power management circuits in mobile phones, fax machines, computer motherboards.
4. Key Advantages
High Power Density – 2W in a 2512 package enables higher power designs within limited PCB space.
Wide Temperature Stability – ±100ppm/℃ TCR ensures stable resistance under extreme conditions, outperforming standard CR series (±200 to ±400ppm/℃).
High Reliability – AEC-Q200 certification validates performance through temperature cycling, humidity load life, and solvent resistance tests.
Standardized Packaging – 2512 package compatible with mainstream SMT processes, tape-and-reel packaging (4000 pcs/reel) supports automated assembly.
5. Market Positioning
The CRH series is positioned in the "high power density + wide-temperature stability" industrial and automotive-grade market. With the trend toward domestic substitution, CRH series combines thick film cost advantages with AEC-Q200 certification, occupying a significant position in the mid-power thick film chip resistor market. The 2512 package achieving 2W is a common choice for power supplies and industrial PCBs.
