BOURNS CRA Series Current Sense Resistor, 0R1, 3W, 2512 [6432 Metric]

The BOURNS CRA Series is a line of precision, high-power current sense chip resistors, expertly engineered for accurate current monitoring in demanding electronic circuits. Presented in the compact 2512 6432 Metric standard case size, they offer an excellent blend of performance, space-saving design, and cost-effectiveness, making them a versatile choice for a wide range of applications.

These resistors feature a special alloy element with a very low resistance value of 0.1 ohm (0R1), allowing for minimal voltage drop while accurately sensing current flow. With a high power rating of 3W, they are capable of handling significant energy dissipation, ensuring reliable operation in power-dense environments. The metal film technology provides excellent stability and a tight tolerance of ±1%, guaranteeing consistent and precise performance.

Key Features & Benefits

• Precision Sensing: The special alloy construction and tight tolerance ensure accurate and reliable current measurement.
• High Power Handling: A robust 3W power rating allows for use in high-current applications without performance degradation.
• Low Parasitic Inductance: With an inductance of less than 5nH, these resistors are ideal for high-frequency switching circuits, minimising unwanted effects.
• Excellent Temperature Stability: A low temperature coefficient ensures minimal resistance change over a wide operating temperature range from -55°C to +170°C.
• Automotive Grade: Qualification to AEC-Q200 standards confirms their suitability for use in demanding automotive electronic systems.
