Procurement Notes

Verify the specific package configuration and pinout compatibility with your PCB layout before ordering. Confirm that the operating frequency range of 50 Hz to 400 Hz aligns with your system requirements. Ensure the primary current rating of 10 A maximum is sufficient for your application's peak load conditions. Cross-reference the datasheet specifications for thermal performance under expected operating loads.

Selection Notes

Select this component when precise current sensing is required for frequencies between 50 Hz and 400 Hz. The 1:166 turns ratio determines the output signal scaling relative to the primary current. Consider the through-hole mounting requirement during mechanical design phases. Evaluate the secondary resistance value for impact on downstream circuit loading and signal integrity.
