CRH2512F150KE04Z 2512 150K 2W Ever Ohms Resistor Product Specifications
1. Product Overview
CRH2512F150KE04Z is a typical model of Ever Ohms (Tian Er Technology) CRH series high-power thick-film chip resistors. Through ceramic substrate thermal optimization and thick-film paste formulation improvements, this series increases the rated power from the conventional 1W to 2W in the standard 2512 package, achieving a power density of 70W/cm² — approximately 40% higher power handling capability compared to standard resistors of the same size.
CRH2512F150KE04Z adopts the 2512 imperial package (metric 6432, 6.35×3.20mm), with a nominal resistance of 150KΩ, ±1% tolerance (F-grade), 2W rated power, and ±100ppm/℃ temperature coefficient. The product is certified under ISO-9001 and ISO-TS16949 quality management systems, compliant with RoHS and REACH environmental regulations, and is lead-free and halogen-free.

4. Product Features
High Power Density. The most prominent technical advantage of CRH2512F150KE04Z lies in its "power-up" design. Standard 2512 package thick-film resistors typically offer 1W rated power, whereas this product achieves 2W in the same physical footprint. This enables engineers to implement higher-power designs within limited PCB space without increasing package size or using multiple parallel resistors.
Wide Temperature Range Stability. The -55℃ to +155℃ operating temperature range, combined with a ±100ppm/℃ low temperature coefficient (TCR), ensures resistance value consistency in extreme environments. The resistive element is manufactured using thick-film technology, with 96% alumina ceramic as the substrate and ruthenium-based oxide paste screen-printed and sintered at 850℃ to form the resistor layer. A glass glaze protective coating provides excellent moisture and corrosion resistance.
High Reliability. The product is AEC-Q200 automotive electronics standard certified. AEC-Q200 certification signifies that the product has passed a series of rigorous tests including temperature cycling, humidity load life, and solvent resistance, making it suitable for applications with extremely high reliability requirements.
5. Typical Applications
The CRH2512F150KE04Z's unique combination of 2512 150K 2W — high resistance with high power — makes it suitable for the following applications:
-
Power Management: Startup resistors and RC snubber circuit resistors in switching power supplies. The 150KΩ high resistance combined with 2W power margin ensures no thermal failure in high-voltage startup circuits and surge absorption scenarios. Suitable for LED lighting drivers, power adapters, and server power supply filtering.
-
Industrial Control and Measurement: Load resistors for PLC control circuits, standard loads for 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 applications demanding high reliability.
-
Consumer Electronics and Communications: Power adapters, chargers, and communication base station power modules in high-density PCB layouts.
6. Model Differentiation Note
It is important to note that the Ever Ohms CRH series also includes the CRH2512J150KE04Z model, which shares the same 150KΩ resistance and 2W power rating but offers ±5% (J-grade) tolerance. The CRH2512F150KE04Z described in this document provides ±1% (F-grade) precision, suitable for precision circuit designs with tighter tolerance requirements. Please confirm the specific model based on your circuit precision needs.
