3. Key Features and Advantages
Thick Film Technology: CRH2512F47R0E04Z utilizes mature thick film resistor technology, with resistive paste screen-printed on alumina substrate and sintered at high temperature. This technology offers an excellent balance between cost and performance, suitable for high-volume production.
High Power Density: Achieving 2W rated power in 2512 package size represents a high power density level. This is particularly valuable for circuit designs requiring significant power handling in limited PCB space. A 30% power derating margin is recommended for practical applications.
Temperature Stability: The ±100PPM/℃ temperature coefficient ensures stable resistance across the -55℃ to +155℃ operating range, critical for applications requiring consistent performance under varying environmental conditions.
Environmental Compliance: The product meets RoHS requirements and contains no REACH SVHC substances, satisfying global environmental regulations.
4. Typical Applications
The 2512 47R 2W specification makes CRH2512F47R0E04Z particularly suitable for:
-
Power Management Circuits: Current limiting resistors in switching power supplies, feedback resistors, and power absorption circuits in power adapters
-
Industrial Control Equipment: Signal conditioning and power processing in PLCs, VFDs, and servo drives
-
Communication Equipment: Power resistors in telecom power supplies and RF amplifier bias circuits
-
Automotive Electronics: On-board power management and current sensing in BMS systems
-
Consumer Electronics: LED drivers, PC motherboards, and fast charger adapters

6. Selection Guidelines
When selecting CRH2512F47R0E04Z, consider the following:
-
Resistance Value Verification: "47R" in the model indicates 47Ω; distinguish from 47KΩ (47,000Ω) to avoid selection errors.
-
Tolerance Selection: ±1% tolerance (F grade) is suitable for precision circuits like power supply feedback loops. For general applications, consider ±5% tolerance (J grade) for cost reduction. CRH series supports multiple tolerance grades including ±0.1%, ±0.5%, ±1%, ±2%, and ±5%.
-
Thermal Management: 2W resistors generate significant heat during operation; adequate copper heatsinking area should be provided in PCB layout.
-
Minimum Package Quantity: The minimum package quantity is 4000 pcs/reel; consider this when planning bulk procurement.
Summary
CRH2512F47R0E04Z from Ever Ohms CRH series delivers 2512 package, 47Ω resistance, and 2W power rating with thick film technology, ±1% tolerance, and ±100PPM temperature coefficient. It offers broad application compatibility across power management, industrial control, communication equipment, and automotive electronics.
