Bourns CRF Series Current Sense Resistor 0.01Ω 0.5W 0805

The Bourns CRF Series Current Sense Resistor is a high-power, thick-film component engineered for precision current measurement in demanding electronic circuits. Featuring an extremely low resistance value of 0.01Ω, it provides accurate sensing with minimal voltage drop, making it indispensable for power management and monitoring applications.

This resistor is built on an industry-standard 0805 footprint (2012 metric), offering a compact solution for space-constrained PCB designs. Its high power density allows it to handle up to 0.5W at 70°C, making it suitable for power supplies, motor drives, battery management systems, and other high-current circuits. The component's construction results in very low inductance (less than 5nH), ensuring stable performance and minimising noise in fast-switching environments.

Key Features & Benefits

• Precision Sensing: Low resistance value and a tight ±1% tolerance enable highly accurate current measurement.
• High Power Handling: A 0.5W power rating at 70°C provides reliability in high-demand applications.
• Stable Performance: Low inductance and a low thermal EMF (less than 3 µV/°C) minimise measurement errors and ensure signal integrity.
• Robust Construction: Thick-film technology on a ceramic substrate offers durability and consistent performance.
• Industry Compliance: The resistor is AEC-Q200 qualified for automotive applications and is fully RoHS compliant, meeting stringent environmental and reliability standards.
• Automated Assembly: Supplied in surface-mount packaging, it is perfectly suited for high-speed, automated pick-and-place manufacturing processes.

With an operating temperature range of –55°C to +170°C, this component is built to perform reliably in extreme environments, from under-bonnet automotive electronics to industrial control systems.
