53200C

Overview

The Murata Power Solutions 53200C is a surface-mount current sense transformer designed for high-accuracy AC current sensing applications. It features a 1:200 turns ratio and operates within a frequency range of 50 kHz to 500 kHz. The device has a primary resistance of 7 mOhm and a secondary resistance of 34 Ohm, with an inductance of 8 mH. Rated for 10 A, it utilizes a compact SMD package suitable for automated assembly.

Feature Summary

• High-accuracy current sensing capability
• Wide operating frequency range from 50 kHz to 500 kHz
• Compact surface-mount design for PCB integration

Applications

• AC current monitoring in power supplies
• Feedback control loops in switching regulators
• Over-current protection circuits

Procurement Notes

Verify the specific ordering suffix and tape/reel configuration against the official datasheet before procurement. Confirm that the component meets all required safety certifications for the target application environment. Ensure compatibility with standard reflow soldering profiles specified by the manufacturer.

Selection Notes

Select this component when a wide bandwidth up to 500 kHz is required for precise current waveform reconstruction. The 1:200 ratio provides sufficient signal amplitude for downstream processing while maintaining isolation. Consider the low primary impedance for minimal insertion loss in high-current paths.

Part Context

This part belongs to the Murata 5300 Series of current transformers, which are engineered for board-mounted applications requiring reliable galvanic isolation between primary and secondary circuits. The series offers various ratios and packages to suit different current levels and form factors.

Replacement Considerations

Direct substitutes must match the 1:200 ratio, 50-500 kHz frequency range, and 8 mH inductance. Verify pinout compatibility and physical dimensions if space constraints exist. Consult official cross-reference lists for equivalent components with identical electrical characteristics.
