CRH1206F1R60P05S 1206 1.6R 0.5W High-Power Low-TCR Chip Resistor

1. Product Overview

The CRH1206F1R60P05S is a high-power thick film chip resistor from Ever Ohms' CRH series. It delivers a 0.5W power rating within the standard 1206 footprint (3.2mm × 1.6mm) while maintaining stable current handling at a low 1.6Ω resistance value. Compared to the CRH1206F1R80P05S (1206 1.8R 0.5W) in the same series, the CRH1206F1R60P05S offers a lower resistance for circuit nodes requiring higher current-carrying capability.

2. Part Number Decoding

The Ever Ohms CRH naming convention follows a logical structure: CRH designates the high-power thick film chip resistor series, distinct from the standard CR series. 1206 is the imperial package code. F indicates ±1% resistance tolerance (B = ±0.1%, D = ±0.5%, J = ±5%). In 1R60, the “R” represents the decimal point, giving a nominal resistance of 1.60Ω. P05 is the power code for 0.5W (1/2W). The trailing S denotes packaging and environmental marking.

3. Key Electrical Specifications

At 1.6Ω, the design constraint is dominated by temperature rise and power dissipation rather than voltage withstand. At the rated 0.5W, the continuous current capacity is approximately 0.56A. A 1.5× to 2× power derating margin is recommended for long-term reliability.

4. Technical Advantages

Doubled power density without PCB redesign. Standard 1206 thick film resistors are typically rated at 0.25W. The CRH series achieves 0.5W in the same footprint through a high-alumina ceramic substrate (Al₂O₃ ≥ 96%), ruthenium-based resistive paste, and a three-layer termination structure. Existing 1206 pads and PCB layouts require no modification.

Optimized low-resistance current handling. At 1.6Ω, the resistor is commonly used in current limiting, bleeder, soft-start, and current feedback loops. The CRH series employs optimized electrode geometry and paste formulation in the low-resistance range to minimize contact resistance error.

Thick film pulse tolerance. The thick film process on an alumina substrate provides good short-duration overload capability, making the resistor suitable for inrush current and load transient scenarios where resistance drift or film damage must be avoided.

5. Typical Applications

The CRH1206F1R60P05S suits applications demanding high power density and compact layout: switch-mode power supply current limiting, industrial control current sensing, LED driver ballast resistors, BMS pre-charge circuits in new energy vehicles, and fast-charging power loops in consumer electronics. Its -55°C to +155°C operating range supports use in automotive and industrial environments.
