CT06-250

Overview

The CT06-250 is a low-profile surface-mount current sense transformer from the CT06 series, manufactured by ICE Components. It features a 1:250 turns ratio and supports a maximum primary current of 18 A with an operating frequency up to 500 kHz. The secondary winding exhibits a maximum resistance of 37.2 Ohms and a maximum inductance of 8.75 mH. Designed for switch-mode power supply applications, it provides electrical isolation between the high-voltage primary circuit and the sensing electronics.

Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• Provides galvanic isolation between primary current path and control circuitry
• Optimized for high-frequency operation up to 500 kHz

Applications

• Switch-mode power supply (SMPS) current monitoring
• Overcurrent protection circuits
• Power factor correction (PFC) stages

Procurement Notes

Verify the specific manufacturer part number against official ICE Components documentation to ensure authenticity. Confirm that the component meets the required insulation and safety standards for your target application. Check for any specific handling or storage requirements indicated in the datasheet before procurement.

Selection Notes

Select this component when a 1:250 turns ratio is required for current sensing in high-frequency switching environments. Ensure the primary current rating of 18 A aligns with the maximum expected load. Verify that the secondary impedance characteristics are compatible with the input requirements of the downstream sensing amplifier or controller.

Part Context

This component belongs to the CT06 series of low-profile SMT current sense transformers. The series offers various turns ratios ranging from 1:50 to 1:250, all sharing similar physical dimensions and mounting characteristics. The CT06-250 specifically addresses applications requiring higher step-down ratios for precise current measurement in high-current scenarios.

Replacement Considerations

Consult the official CT06 series datasheet for confirmed substitute part numbers within the same family. Cross-referencing with other manufacturers requires careful verification of turns ratio, saturation current, and package dimensions.
