Procurement Notes

Verify the specific inductance value associated with the suffix, as the RN112-2-02 designation may correspond to variants such as 1 mH or 1.8 mH depending on the full part number extension. Confirm that the required voltage rating aligns with the 300V AC specification typical for this series. Ensure the through-hole pin configuration matches the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when a common mode choke with 2 A current handling and approximately 1 mH inductance is required. The RN112 series offers high saturation resistance suitable for noisy environments. Verify that the operating temperature range of -40°C to +100°C meets the environmental constraints of the application. Ensure the physical footprint of 17.7 x 17.1 x 12.6 mm fits within the available board space.

Part Context

The RN112-2-02 belongs to Schaffner's RN series of common mode chokes. This series is engineered for EMC compliance in power electronics.
