CRH1206J620KP05Z Ever Ohms Resistor - Technical Parameter Introduction
I. Product Overview
CRH1206J620KP05Z is a representative model from the CRH series of high-power thick film chip resistors manufactured by EVER OHMS TECHNOLOGY CO., LTD.. Established in 1988 and headquartered in Kaohsiung, Taiwan, Ever Ohms is a specialized manufacturer of chip resistors and resistor networks, with product lines spanning from general-purpose to high-reliability series.
This model features a standard 1206 package (metric size 3.2mm × 1.6mm), with a nominal resistance of 620KΩ (620KR), tolerance of ±5% (J-grade), rated power of 0.5W (1/2W), and a temperature coefficient of ±100ppm/℃. The core design philosophy of the CRH series is to achieve higher power handling capacity within standard package dimensions — the 1206 package is upgraded from 0.25W of the standard CR series to 0.5W, doubling the power density.

IV. Technical Characteristics and Advantages
Leading Power Density: CRH1206J620KP05Z achieves 0.5W rated power within the standard 1206 package. Conventional 1206 thick film resistors typically support only 0.25W. The CRH series achieves higher thermal dissipation efficiency within the same package volume through optimized thick film paste formulation, improved ceramic substrate thermal pathways, and enhanced electrode heat dissipation structures.
Superior Temperature Stability: The ±100ppm/℃ temperature coefficient ensures stable resistance values across a wide temperature range. Compared to standard CR series which typically exhibit TCR levels of ±200ppm/℃ to ±400ppm/℃ in equivalent packages, the CRH series maintains more stable resistance precision in industrial power supplies under prolonged full-load operation or automotive electronics in wide-temperature environments.
Wide Temperature Operation: The -55℃ to +155℃ operating temperature range covers applications from low-temperature environments to high-temperature industrial scenarios.
Compact Size with High Power: The 1206 package (3.2mm × 1.6mm) delivers 0.5W power while maintaining a compact PCB footprint, effectively saving board space and balancing power requirements with design flexibility.
V. Comparison with CR Series Standard Thick Film Resistors
| Comparison Dimension | CRH Series (High Power) | CR Series (Standard) |
