Bourns CRM Series SMD Current Sense Resistor 0R1, 0.5W, ±1%, 1206

The Bourns CRM Series SMD Current Sense Resistor is a high-performance, thick-film chip resistor designed for accurate and reliable current sensing in demanding electronic circuits. Built on a robust ceramic substrate with a thick-film resistive layer made from a mixture of metal oxides, it offers excellent stability and power handling. The component features electroplated tin (Sn) outer terminations for reliable board soldering and is protected by a durable epoxy overcoat layer, ensuring long-term performance in various environments.

This precision resistor operates across a wide temperature range from -55°C to +155°C, making it suitable for industrial and automotive applications where thermal conditions can vary. With a 0.1-ohm (0R1) resistance and a tight ±1% tolerance, it provides the accuracy necessary for critical measurement and control functions. The 1206 3216 Metric package offers a balance of compact size and a 0.5W power rating, ideal for space-constrained PCB designs requiring efficient power dissipation.

Typical applications for this current sense resistor include:

• Current sensing in power management and monitoring circuits.
• Power supplies, including switch-mode designs.
• Stepper motor drives for precise current control.
• Snubber resistors in flyback power supplies to suppress voltage spikes.

Engineers and designers can rely on the Bourns CRM Series for consistent quality, backed by a ±100ppm/°C temperature coefficient for stable operation over its full operating range. Its surface-mount design facilitates automated assembly, streamlining production processes.
