3. Technical Features
High Power Density Design – The CRH2512F330RE04Z delivers 2W rated power within the standard 2512 package footprint. Conventional 2512 thick film resistors typically support only 1W; the CRH series doubles the power density through thick film paste optimization and electrode process improvements. This capability is critical for power supplies, industrial controls, and communication equipment where space and thermal management are constrained.
Temperature Stability – The ±100ppm/℃ TCR ensures stable resistance values across a wide temperature range. Combined with the -55℃ to +155℃ operating temperature range, this model suits applications from cold environments to high-temperature industrial scenarios.
Reliability and Miniaturization – The CRH2512F330RE04Z features small size, light weight, and high reliability. The 2512 package delivers 2W power while maintaining a compact PCB footprint, balancing power requirements with layout flexibility.
4. Typical Applications
The CRH2512F330RE04Z is suitable for:
-
Power Equipment: Switching power supplies, lighting equipment, power adapters
-
Communication Equipment: Mobile phones, fax machines, base station equipment
-
Computing & Peripherals: Motherboards, servers, storage device power management
