CRH1206J5R60P05Z 1206 5.6R 0.5W Ever Ohms Resistor Performance Introduction

I. Product Overview

CRH1206J5R60P05Z is a standard model from Ever Ohms Technology Co., Ltd.'s CRH series high-power thick film chip resistors. Founded in 1988 and headquartered in Kaohsiung, Taiwan, China, Ever Ohms is an established manufacturer specializing in the R&D and production of chip resistors and resistor arrays, certified with ISO9001, IATF16949, and AEC-Q200 automotive-grade standards.

This model features a standard 1206 package (metric size 3.2mm × 1.6mm), with a nominal resistance of 5.6Ω (5.6R), ±5% tolerance (J-grade), rated power of 0.5W (1/2W), and a temperature coefficient of ±400ppm/℃. The core design philosophy of the CRH series is to achieve higher power handling capability within standard package dimensions—the 1206 package power rating is doubled from 0.25W in the conventional CR series to 0.5W.

IV. Technical Characteristics and Performance Advantages

Leading Power Density. The CRH1206J5R60P05Z achieves 0.5W rated power within the standard 1206 package. Conventional 1206 thick film resistors typically support only 0.25W (1/4W). 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. The CRH series employs ruthenium-based oxide paste screen printing technology, sintered on alumina ceramic substrates at high temperatures, delivering significantly improved power density.

Wide Temperature Operation. The -55℃ to +155℃ operating temperature range covers applications from low-temperature environments to high-temperature industrial scenarios. This 1206 5.6R 0.5W resistor can operate at full rated power at 70℃ ambient temperature, with power derating required as temperature increases.

Process and Material Advantages. The resistor body is formed by printing high-stability metal glass glaze paste onto 96% alumina ceramic substrates, sintered at high temperature to create a dense resistive layer. The 96% alumina ceramic substrate offers excellent thermal conductivity, insulation, and mechanical shock resistance, efficiently dissipating heat generated during operation to prevent localized overheating and component failure. The terminal electrodes feature a silver-nickel-tin三层 structure: the inner silver layer ensures ohmic contact with the resistive layer, the intermediate nickel layer acts as a barrier against solder penetration, and the outer pure tin plating provides excellent solderability.

Environmental Compliance. This 1206 5.6R 0.5W resistor fully complies with RoHS directive restrictions on hazardous substances and meets REACH regulations regarding SVHC declaration. The lead-free terminal electrode process enables direct entry into EU and global mainstream market supply chains.

V. Typical Application Scenarios

The low resistance value of 5.6Ω combined with 0.5W power margin gives this 1206 5.6R 0.5W resistor clear application positioning across multiple domains:

Current Sensing and Sampling. The low 5.6Ω resistance is suitable for current sampling applications, used in power management, motor drive, and other circuits for current detection and feedback control, with 0.5W power ensuring controllable temperature rise under normal operating currents.

Power Modules and DC-DC Converters. In switching power supplies and DC-DC converters, this 1206 5.6R 0.5W resistor can be used in feedback networks, current limiting protection, and soft-start circuits. The ±400ppm/℃ temperature coefficient ensures parameter stability across wide temperature ranges.

Automotive Electronics. This model meets AEC-Q200 automotive-grade standards, suitable for new energy vehicle BMS battery management systems, on-board chargers, body control modules, and other automotive electronic applications.

Industrial Control and Communication Equipment. In industrial servo drives, communication base station power modules, server power systems, and other scenarios, this 1206 5.6R 0.5W resistor handles current limiting and bias setting functions.
