Procurement Notes
Verify the specific part number suffix against official Vigortronix documentation to ensure correct ratio and tolerance specifications. Confirm that the through-hole package style matches your board layout requirements. Check for any epoxy encapsulation details if environmental protection is required for your specific assembly process.
Selection Notes
Select this component when a 1:1000 ratio is required for 10A nominal currents. Ensure the operating frequency falls within the 20Hz to 20kHz range. Consider the 1% tolerance requirement for precision measurement circuits. Verify that the 100-ohm secondary resistance aligns with your downstream amplifier or ADC input impedance.
