Resistor 1 OHM 1/2W 1% Metal Film

High-Precision Metal Film Construction

Engineered for low-noise electronic circuits, this 1 Ohm axial metal film resistor delivers a reliable 0.5 Watt (1/2 Watt) power rating paired with a tight +-1% resistance tolerance. Constructed by vacuum-depositing a refined metal layer onto a high-purity ceramic substrate, this component offers superior long-term stability, a minimal voltage coefficient, and significantly lower thermal noise compared to standard carbon composition alternatives.

Thermal Stability and Environmental Compliance

Designed to operate dependably across a wide temperature range from -55 degrees C to +155 degrees C, this precision passive component features a flame-retardant epoxy coating that guards against environmental contamination and mechanical stress. The lead-free, RoHS-compliant tin-plated copper leads provide excellent solderability for automated wave soldering or hand assembly.

Target Applications and Use-Cases

With its low nominal resistance and high tolerance precision, this 1 Ohm resistor is ideal for current-sensing applications, precision power supply feedback loops, LED drive current regulation, and audio crossover networks. Its low self-inductance and stable performance under load make it an essential building block for industrial controls, test and measurement equipment, and high-fidelity audio electronics.
