Common Mode Chokes Procurement Notes

Verify the complete part number including the suffix 'T' for tape and reel packaging when ordering. Confirm that the 100 mA rated current meets the specific application requirements. Ensure the 4 Ohm DC resistance is acceptable for the signal integrity of the target circuit. Check lead times as they may vary based on manufacturer availability.

Common Mode Chokes Selection Notes

Select this component when a compact, dual-line filter is required for high-frequency noise attenuation. The 75 Ohm impedance value targets specific frequency ranges typical in digital signaling. Consider the 100 mA current limit to ensure the device does not saturate during normal operation. The 1210 package size offers a balance between footprint area and performance capabilities.

Common Mode Chokes Part Context

This component belongs to Littelfuse's EMI filter product family, specifically categorized under common mode chokes. These devices are engineered to minimize disruptive frequencies in cables and electronics without blocking main electrical signals. The series typically incorporates design considerations for space-constrained printed circuit board layouts.

Common Mode Chokes Replacement Considerations

Consult official Littelfuse documentation for direct cross-references. Verify that any substitute maintains the 75 Ohm impedance at 100 MHz and the 100 mA current rating. Ensure the replacement package matches the 1210 surface mount form factor.
