CRH2512J150KE04Z 2512 150K 2W High Power Thick Film Chip Resistor – Comprehensive Analysis

I. Product Number Decoding

CRH2512J150KE04Z is a standard model from EVER OHMS’ CRH series of high-power thick film chip resistors. The model number breaks down as follows:

• CRH: EVER OHMS high-power thick film chip resistor series code

• 2512: Imperial package size, corresponding to metric 6432 (6.35×3.20mm)

• J: Tolerance grade, ±5%

• 150K: Nominal resistance 150kΩ

• E04: Packaging code – E for tape packaging, 04 for 4000 pieces per reel

• Z: Environmental标识, lead-free and RoHS compliant

II. Product Characteristics

Key electrical parameters of CRH2512J150KE04Z:

The resistor is manufactured using thick film technology on a 96% alumina ceramic substrate, with a ruthenium-based oxide paste screen-printed and sintered at 850℃. The CRH series’ most distinctive technical feature is its “power-boost” design – standard 2512 thick film resistors typically support only 1W, while the CRH series achieves 2W through optimized ceramic substrate thermal conductivity and improved thick film paste formulations, delivering a power density of up to 70W/cm². A glass glaze coating provides excellent moisture and corrosion resistance.

The product is certified under ISO-9001 and ISO-TS16949 quality management systems and complies with AEC-Q200 automotive electronics standards. It is RoHS and REACH compliant, lead-free and halogen-free.

III. Applications

With its 2512 150K 2W parameter combination – high resistance paired with high power – CRH2512J150KE04Z finds wide application in the following scenarios:

Power Management: Used as startup resistors and RC snubber circuit resistors in switching power supplies. The 150kΩ high resistance combined with 2W power margin ensures reliable operation without overheating in high-voltage startup circuits and surge absorption scenarios. Also applicable in LED lighting drivers, power adapters, and server power supply filtering.

Industrial Control & Measurement: Serves as load resistors in PLC control circuits, standard loads in ATE test systems, and precision voltage divider components in meters and navigation equipment.

Automotive Electronics: With AEC-Q200 certification, suitable for new energy vehicle battery management systems (BMS), engine control units, and other high-reliability applications.

Consumer Electronics & Communications: Applicable in high-density PCB layouts for power adapters, chargers, and communication base station power modules.

IV. Advantages

High Power Density is the most prominent advantage of CRH2512J150KE04Z. Standard 2512 packages typically support only 1W, while this product achieves 2W – approximately a 40% increase in power density compared to conventional same-size resistors. Engineers can implement higher-power designs within limited PCB space without increasing package size.

Wide Temperature Adaptability: The -55℃ to +155℃ operating temperature range, combined with a low ±100ppm/℃ temperature coefficient, ensures resistance stability in harsh environments.

High Reliability: AEC-Q200 certification means the product has passed rigorous tests including temperature cycling, humidity load life, and solvent resistance.

Standardized Packaging: The 2512 package is compatible with mainstream SMT processes, and tape-and-reel packaging (4000 pieces/reel) supports automated assembly.

V. Market Positioning

CRH2512J150KE04Z is positioned in the mid-range segment of the medium-to-high power thick film chip resistor market. Primary target customers are R&D and manufacturing enterprises in industrial power supplies, automotive electronics, and communications equipment. In the 2512 150K 2W specification, the EVER OHMS CRH series competes directly with TE Connectivity’s CRGH series and Stackpole’s HVCB series. The CRH series offers competitive advantages in pricing and supply flexibility.

In volume purchases (10,000+ units), the unit price reaches approximately RMB 0.30 including tax, delivering excellent cost-performance. The market positioning precisely covers the full-cycle demand from R&D prototyping to mass production.
