CRH1206F1R50P05S 1206 1.5R 0.5W High-Power Low-TCR Resistor
Product Overview
The CRH1206F1R50P05S is a high-power thick film chip resistor from Ever Ohms' CRH series, featuring a 1206 package (metric 3216, approximately 3.2mm × 1.6mm), a resistance value of 1.5Ω, and a power rating of 0.5W. This 1206 1.5R 0.5W resistor delivers twice the power handling capability of standard 1206 thick film resistors (typically 0.25W), enabling designers to handle higher power loads without changing the PCB footprint.

Design Advantages
Doubled Power Density: The CRH series employs high-alumina ceramic substrates (Al₂O₃ ≥96%), ruthenium-based thick film resistive layers, and three-layer terminal electrodes to achieve 0.5W in a standard 1206 footprint. This means existing 1206 pad layouts require no modification — engineers can drop in the CRH1206F1R50P05S as a direct replacement to resolve localized overheating or insufficient power margin.
Low-Resistance Stability: At 1.5Ω, the resistor operates in the low-resistance range where contact resistance and temperature rise are the primary engineering concerns. Ever Ohms' CRH series uses optimized electrode structures and resistive paste formulations to minimize contact resistance errors, ensuring the actual resistance remains close to the nominal value.
Pulse Withstanding: The thick film construction combined with the alumina substrate provides good short-term overload capability, making the resistor resistant to resistance drift or film burnout during power-up inrush currents and load transients.
Typical Applications
This 1206 1.5R 0.5W resistor is suited for current limiting and bleeder circuits in AC-DC adapters, LED driver current setting, industrial control current sensing, and passive balancing branches in battery protection boards. The 0.5W power rating allows direct series connection in higher-voltage circuit nodes, simplifying circuit design.
