CSE5-100401

Overview

The Triad Magnetics CSE5-100401 is a board-mount current transformer designed for high-frequency applications. It features a turns ratio of 1:40 and a minimum inductance of 320 µH. The secondary DC resistance is specified at a maximum of 1.35 ohms. This component is engineered for surface mount technology (SMD/SMT) installation, providing reliable current sensing capabilities within compact power conversion systems.

Feature Summary

Designed for use in switching power supplies and power factor correction circuits
Provides accurate current sensing through a defined 1:40 turns ratio
Engineered for surface mount board mounting to facilitate automated assembly

Applications

Switching power supplies
Power factor correction circuits
General power conversion applications

Procurement Notes

Verify the specific datasheet version when procuring to ensure compliance with the latest electrical specifications. Confirm that the secondary DC resistance does not exceed the maximum limit of 1.35 ohms for your circuit design. Ensure the manufacturing date code aligns with your inventory requirements to maintain component freshness and reliability standards.

Selection Notes

Select this component when a 1:40 turns ratio and 320 µH minimum inductance are required for current sensing. It is suitable for designs prioritizing surface mount integration over through-hole options. Consider the maximum secondary resistance of 1.35 ohms when calculating voltage drops in the sensing circuitry to ensure signal integrity.

Part Context

This part belongs to the CSE5 series of current sense transformers from Triad Magnetics. These components are specialized for high-frequency operation, distinguishing them from standard low-frequency isolation transformers. The series is tailored for modern electronic power architectures requiring precise current monitoring.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing footprints and electrical parameters before considering alternative manufacturers.
