CSE5-100601

Overview

The CSE5-100601 is a high-frequency current sense transformer from the Triad Magnetics CSE5 series, designed for surface mount applications. It features an EE5 core structure with a turns ratio of 1:60 and a minimum secondary inductance of 720 µH. The component has a maximum secondary DC resistance of 1.75 Ohms and supports a primary current rating of 20 amps. Its physical dimensions are 6.90 mm x 7.70 mm with a maximum height of 5.3 mm. The device is optimized for operation at frequencies of 250 kHz and above.

Feature Summary

• Surface mount EE5 design optimized for high-frequency performance
• High isolation capability suitable for power supply monitoring
• Compact footprint with low profile construction

Applications

• Switching power supply current sensing
• Inverter control circuits
• Motor drive feedback systems

Procurement Notes

Verify that the application frequency meets the minimum requirement of 250 kHz to ensure optimal transformer performance. Confirm that the PCB layout accommodates the specific EE5 package dimensions of 6.90 mm by 7.70 mm. Ensure the primary circuit can handle the rated 20 amp current without exceeding thermal limits. Check secondary load impedance against the specified 1.75 Ohm DC resistance to maintain signal integrity.

Selection Notes

Select this component when a high turns ratio of 1:60 is required for precise current measurement in high-frequency environments. The EE5 form factor provides a balance between electrical performance and board space efficiency. Consider the 720 µH minimum secondary inductance for filtering requirements. This part is suitable for designs prioritizing compactness and high-speed switching capabilities over through-hole alternatives.

Part Context

The CSE5-100601 belongs to the CSE5 series of current sense transformers manufactured by Triad Magnetics. This series is engineered specifically for surface mount technology (SMT) to support modern automated assembly processes. The EE5 core geometry distinguishes it from other toroidal or E-core variants within the manufacturer's portfolio, offering a standardized solution for isolated current detection in compact power electronics.

Replacement Considerations

Direct substitutes within the same series include CSE5-100201, which shares similar structural characteristics but may differ in electrical parameters such as turns ratio or inductance values. Verify compatibility before substitution.
