Procurement Notes

Verify the exact part number suffix, as variants like RN102-2-02-1M1 exist with identical core specifications but potentially different packaging or testing standards. Confirm that the 1.1 mH inductance and 2 A current rating align with your circuit requirements before procurement. Ensure compatibility with through-hole assembly processes.

Selection Notes

Select this component when a 1.1 mH common mode choke is required for low-current power line filtering. The 70 mΩ DC resistance minimizes voltage drop, while the 2 A rating suits moderate load applications. Verify that the horizontal form factor fits the PCB layout constraints and that the operating temperature range meets environmental demands.
