Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to confirm electrical tolerances and insulation ratings. Ensure the selected component matches the required current ratio and frequency bandwidth for the target application circuit. Cross-reference the package style and termination type with the assembly requirements before finalizing the purchase order.

Selection Notes

Select this component when precise AC current monitoring is required without breaking the main circuit path. The 2000:1 ratio suits applications needing low secondary currents for ADC interfacing. Consider the 90 Ohm DC resistance for burden resistor calculations. Validate that the operating frequency falls within the specified 20 Hz to 200 kHz range for accurate signal reproduction.
