CT08-1200

Overview

The CT08-1200 is a tombstone-style through-hole current sense transformer from ICE Components. It features a 1:1200 turns ratio and supports a maximum frequency of 3.5 kHz to 4.7 kHz. The device has a rated current of 50 A, an inductance of 10 mH, and a secondary resistance of 40 Ohms. Designed for encapsulated construction, it operates within a frequency range of 40 Hz to 5 kHz and is suitable for bipolar applications only.

Feature Summary

• Encapsulated construction for high current density
• Tombstone through-hole mounting style
• High turns ratio of 1:1200

Applications

• Switching power supplies
• Motor controls

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct termination options and packaging details. Confirm that the application environment strictly adheres to bipolar operation requirements, as the component is not suitable for unipolar circuits. Cross-reference the secondary resistance and inductance values with system design specifications to ensure compatibility with existing signal conditioning circuitry.

Selection Notes

Select this component when a high-isolation current sensing solution is required for bipolar AC or pulsed DC signals. The 1:1200 ratio provides significant attenuation for high-current measurements. Ensure the operating frequency remains below the 3.5 kHz to 4.7 kHz limit. The tombstone form factor is ideal for board-level integration where space constraints favor vertical mounting over surface-mount alternatives.

Part Context

This part belongs to the CT08 series of current sense transformers, which are characterized by their robust encapsulated construction and high current density capabilities. The series is designed for board-mount applications requiring reliable isolation between primary and secondary circuits. These components are engineered for use in environments demanding stable performance under varying load conditions.

Replacement Considerations

Consult the official CT08 series datasheet for direct substitutes with matching 1:1200 ratios and similar physical dimensions. Verify that any alternative maintains the 50 A rating and 40 Ohm secondary resistance to preserve circuit integrity.
