Overview
The Schaffner RN102-2-02-1M1 is a horizontal common mode choke designed for power line filtering. It features an inductance of 1.1 mH at a test frequency of 10 kHz, with a tolerance range of -30% to +50%. The component supports a maximum DC current of 2 A and has a typical DC resistance of 70 mOhms. Constructed with ferrite core material, it operates within a temperature range of -40°C to +100°C. The unit utilizes through-hole mounting with dimensions of 18.2 mm x 8.8 mm x 13.5 mm.
Feature Summary
- Horizontal orientation design for PCB integration
- Ferrite core construction for electromagnetic compatibility
- Through-hole termination style
Applications
- Power line filtering applications
- Electromagnetic compatibility (EMC) suppression
- Two-line circuit protection
Procurement Notes
Verify the specific manufacturer designation, as sources list both Schaffner EMC Inc. and TE Connectivity / Schaffner. Confirm the physical orientation matches the horizontal specification required by the design. Ensure the 1.1 mH inductance value aligns with the target filter frequency requirements. Check that the 2 A current rating meets the operational load demands without saturation.
Selection Notes
Select this component when a horizontal form factor is necessary for board layout constraints. The 1.1 mH inductance provides effective noise attenuation at standard testing frequencies. The 70 mOhm DC resistance minimizes power loss in low-current circuits up to 2 A. Verify that the -40°C to +100°C operating range covers the environmental conditions of the intended application.
Part Context
This part belongs to the RN series of common mode chokes from Schaffner. It is functionally similar to the RN112-2-02-1M0 but differs in physical dimensions and orientation. The RN102 variant specifically offers a horizontal profile compared to vertical alternatives like the RN202-2-02-1M1. Both share similar electrical characteristics including 1.1 mH inductance and 2 A current handling capabilities.
Replacement Considerations
The RN202-2-02-1M1 serves as a vertical alternative with identical electrical specifications. The RN112-2-02-1M0 shares the same series but may differ in housing dimensions.
