CT430-HSWF65MR

Current Sensors Overview

The CT430-HSWF65MR is a board-mount current sensor utilizing Allegro’s XtremeSense TMR technology. It features a 16-lead SOIC wide package (7.50mm width) and supports bidirectional measurement of up to 65A peak current. The device operates on a 5.0V supply voltage and delivers total error of less than 1%. Designed for high precision, it functions within an extended temperature range of up to +125°C, making it suitable for demanding industrial and automotive environments requiring low noise and high accuracy.

Current Sensors Feature Summary

• Utilizes patented XtremeSense TMR technology for high-accuracy measurements
• Provides ultra-low noise performance with less than 1% total error
• Supports bidirectional current sensing in a compact 16-lead SOIC wide package

Current Sensors Applications

• Automotive systems requiring precise current monitoring
• Industrial equipment needing high bandwidth sensing
• Consumer electronics applications demanding low power consumption

Current Sensors Procurement Notes

Verify component authenticity through authorized Allegro MicroSystems distributors or certified partners. Confirm the specific suffix matches project requirements. Check for obsolescence notices or lifecycle status updates directly from the manufacturer. Ensure storage conditions comply with moisture sensitivity levels if applicable. Validate that the 16-SOIC wide footprint aligns with existing PCB layouts before finalizing orders.

Current Sensors Selection Notes

Select this sensor when sub-one percent total error is critical for system performance. The 65A peak rating suits moderate-to-high current loads without excessive thermal management. The wide SOIC package facilitates easier surface-mount assembly compared to standard narrow variants. Consider the 5.0V supply requirement against available system rails. Evaluate the +125°C operating limit against ambient environmental constraints.

Current Sensors Part Context

This component belongs to the CT430 series, which leverages Tunnel Magnetoresistance (TMR) technology. This family targets applications requiring superior signal integrity and lower power consumption compared to traditional Hall-effect sensors. The series is designed to meet the rigorous demands of modern automotive and industrial control systems.

Current Sensors Replacement Considerations

Consult official Allegro MicroSystems documentation for direct cross-reference part numbers. Verify pin compatibility and electrical specifications before substituting. Generic alternatives may not match the specific TMR noise characteristics or total error margins.
