Bourns CRM Series Chip Resistor, 1kΩ, ±1%, 2W, 2512

The Bourns CRM Series is a high-power, thick film chip resistor designed for demanding current-sensing and power applications. Constructed from a robust ceramic substrate, a thick film resistive layer—composed of a precise mixture of metal oxides—is printed on to provide stable and reliable resistance. This element is protected by a durable epoxy overcoat, ensuring long-term performance and protection from environmental factors.

The component features electroplated tin (Sn) outer terminations, optimised for excellent solderability in surface-mount assembly processes. With a substantial power rating of 2W, it is engineered to handle significant loads, making it an ideal choice for circuits where heat dissipation and accuracy are critical.

Key Features & Applications

• High-Power Design: A 2W power rating makes it suitable for power-dense applications.
• Precision Tolerance: A tight resistance tolerance of ±1% ensures accurate and consistent circuit performance.
• Wide Temperature Range: Reliable operation across an extensive temperature span from -55°C to +155°C.
• Robust Construction: The combination of a ceramic substrate, thick film element, and epoxy coating provides mechanical strength and environmental protection.
• Surface-Mount Ready: Electroplated tin terminations facilitate efficient PCB assembly.

This resistor is particularly well-suited for current sensing in motor drives and power supplies, power supply circuits, stepper motor drives, and as a snubber resistor in flyback power supply designs. Its combination of high power handling, precision, and robust build makes it a dependable component for professional electronic design and industrial applications.
