CRH1206F330KP05Z 1206 330K 0.5W Ever Ohms Resistor Specifications

1. Product Overview and Part Number Decoding

The CRH1206F330KP05Z is a high-power thick film chip resistor from Ever Ohms' CRH series, delivering a 0.5W power rating within a standard 1206 package—double the power density of conventional 1206 thick film resistors at 0.25W. Ever Ohms Technology, founded in 1988, specializes in the R&D and manufacturing of chip resistors and resistor networks. The company holds ISO 9001 and IATF 16949 certifications, with multiple product lines qualified to AEC-Q200 automotive standards.

The part number follows Ever Ohms' standardized coding system: CRH denotes the high-power thick film resistor series, 1206 indicates the imperial package size (3.2mm × 1.6mm), F represents ±1% tolerance, 330K specifies the 330kΩ nominal resistance, P05 corresponds to the 0.5W power rating, and Z indicates lead-free tape-and-reel packaging.

2. Key Specifications

These specifications are based on Ever Ohms' official datasheet and authorized channel data. The resistor operates at full rated power up to 70°C ambient temperature; above 70°C, power derating applies according to the derating curve, reaching zero at 155°C. At 0.5W, this 1206 330K resistor exceeds the 0.25W typical rating for conventional 1206 thick film resistors, making it suitable for compact boards that require meaningful power headroom.

3. Electrical Characteristics

High power density. The CRH1206F330KP05Z achieves its 0.5W rating through optimized thick film paste formulation, improved ceramic substrate thermal conduction, and enhanced electrode processes. This makes it a practical choice for power modules, industrial control boards, and communication equipment where board space and thermal management are constrained.

Temperature stability. The ±100 ppm/°C TCR ensures controlled resistance drift across a wide temperature range. Compared to standard thick film resistors with ±200 to ±400 ppm/°C drift, this specification provides better resistance consistency in applications exposed to fluctuating ambient temperatures.

Thick film reliability. The resistor uses ruthenium-oxide thick film paste on a 96% alumina substrate, providing solid surge tolerance and long-term stability for circuits subject to inrush currents or transient overloads.

4. Typical Applications

The CRH1206F330KP05Z is commonly specified in:

• Power management: Voltage divider and feedback networks in switching power supplies and DC-DC converters, where the 330kΩ value appears in high-voltage feedback paths.

• Industrial control: PLCs, sensor signal conditioning circuits, and measurement instruments requiring high reliability.

• Communication equipment: Compact base stations and optical modules where high power density supports miniaturized board layouts.

• Automotive electronics: AEC-Q200 equivalent reliability enables use in body control modules (BCM), automotive power supplies, and sensor conditioning circuits.

5. Sourcing and Selection Notes

When specifying this part, apply at least 30% power derating based on actual operating current, and verify that PCB copper area supports adequate heat dissipation. For circuits requiring ±1% accuracy in voltage division or feedback, the F-grade tolerance is appropriate.
