53100C

Overview

The 53100C is a board-mount current transformer manufactured by Murata Power Solutions. It features a primary-to-secondary turns ratio of 1:100 and is designed for surface mount applications. The device operates within a frequency range of 50 kHz to 500 kHz. Key electrical specifications include a primary DC resistance of 7 milliohms, a secondary DC resistance of 5.6 ohms, and an inductance of 2 mH. The component supports a maximum primary current of 10 A. Physical dimensions are 7.20 mm in length, 8.30 mm in width, and a maximum height of 5.40 mm.

Feature Summary

• Provides precise current sensing with a fixed 1:100 transformation ratio
• Optimized for high-frequency operation between 50 kHz and 500 kHz
• Designed for direct surface mount integration onto printed circuit boards

Applications

• Current sensing in switching power supplies
• Overcurrent protection circuits
• Closed-loop control systems for power converters

Procurement Notes

Verify the specific ordering suffix required for your packaging preference, such as tape and reel or cut tape, when placing orders. Confirm that the 10 A primary current rating aligns with your peak load requirements. Ensure the PCB footprint matches the specified 7.20 mm by 8.30 mm dimensions. Check for any recent lifecycle updates or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 1:100 ratio is necessary for accurate current monitoring in high-frequency environments. The low primary resistance minimizes insertion loss in the main power path. Consider the 5.6 ohm secondary resistance for burden resistor calculations. Verify compatibility with standard SMT assembly processes due to the鸥翼 termination style.
