CRH1206F576RP05Z 1206 576K 0.5W TA-I Resistor Characteristics

Product Overview

The CRH1206F576RP05Z is a high-power thick-film chip resistor from TA-I Technology (Ever Ohms), part of the CRH series. It features a 1206 (imperial) package, a nominal resistance of 576KΩ, a rated power of 0.5W, ±1% tolerance, and a temperature coefficient of ±100PPM/℃. TA-I Technology, founded in 1988 and headquartered in Kaohsiung, Taiwan, specializes in chip resistors and resistor networks, holding ISO9001 and IATF 16949 certifications with products compliant to AEC-Q200 automotive standards.

The CRH series represents TA-I's core product line for high power density applications. Through thickened resistive films and reinforced alumina ceramic substrates, it achieves higher power ratings within the same package size compared to standard thick-film resistors. Compared to standard CR series 1206 thick-film resistors (typically rated at 0.25W), the CRH1206F576RP05Z doubles the power handling capability, enabling designers to obtain 0.5W in a conventional 1206 footprint without expanding PCB real estate.

Core Specifications

Key parameters include: resistance 576KΩ, tolerance ±1%, rated power 0.5W at 70℃ ambient temperature, TCR ±100PPM/℃, operating temperature range -55℃ to +155℃, thick-film construction, and compliance with RoHS (2011/65/EU) and REACH requirements. Power derating is required above 70℃ ambient temperature, with a general recommendation to derate to 70% of rated power for long-term reliability.

Technical Characteristics

The CRH series utilizes 96% high-thermal-conductivity alumina ceramic substrates combined with ruthenium-based thick-film paste firing at 850℃. The terminal electrodes employ a silver/nickel/tin three-layer structure, balancing solderability with anti-sulfur performance. The ±1% tolerance satisfies most voltage division and current limiting requirements, while the ±100PPM/℃ TCR provides stable resistance across the wide operating temperature range.

The series carries ISO9001 and IATF 16949 quality certifications and complies with AEC-Q200 automotive standards. The thick-film structure resists sulfur attack, and the optimized thermal design ensures rapid heat dissipation during operation.

Applications

The CRH1206F576RP05Z suits industrial control (servo drives, switching power supplies), automotive electronics (BMS voltage divider networks, OBC, body control modules), telecommunications equipment (base station power modules), and consumer/medical devices requiring stable voltage division or current limiting.
