Overcurrent protection systems
Feedback control loops in switching regulators

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm exact electrical tolerances and mechanical variations. Ensure the selected variant matches the required operating frequency and current ratings for the target application. Cross-reference datasheet specifications with design requirements before finalizing procurement orders.

Selection Notes

Select this component when a robust, encapsulated current transformer is needed for high-current applications up to 35 A. The 50:1 turns ratio suits standard sensing amplifier inputs. Consider the physical footprint and through-hole mounting style during PCB layout. Verify that the 20 kHz to 200 kHz frequency range aligns with the system's switching frequency.

Part Context

This part belongs to the CST series of current sense transformers from Triad Magnetics. These components are designed for board-mount applications requiring reliable current monitoring. The series offers various current ratings and turns ratios to accommodate different power electronics designs.

Replacement Considerations

Consult official Triad Magnetics substitution guides for verified alternatives. Generic replacements may differ in inductance, saturation current, or physical dimensions.
