Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct configuration. Confirm that the required operating frequency and current ratings align with the system design constraints before procurement. Cross-reference the part number with the latest datasheet to validate electrical parameters such as secondary resistance and inductance values.

Selection Notes

Select this component when a precise 1:200 transformation ratio is required for current monitoring. Ensure the application environment accommodates the specified maximum primary current of 18 A. Consider the physical dimensions and surface mount requirements during PCB layout to maintain signal integrity and thermal performance within the defined operational limits.

Part Context

This component belongs to the CT02 series of current sense transformers from ICE Components, Inc. The series offers various turns ratios to suit different sensing needs. The CT02-200 specifically targets applications requiring higher isolation or specific scaling factors compared to lower ratio variants like the CT02-100.

Replacement Considerations

Direct substitutes must match the 1:200 ratio, 18 A rating, and 700 kHz frequency limit. Verify pin compatibility and package dimensions for equivalent replacement options.
