Overview
The Schaffner RN114-1-02 is a current-compensated common mode choke from the RN series, designed for through-hole PCB mounting. It utilizes ferrite core material and features an unshielded construction with solder pad termination. The component operates within a temperature range of -40°C to +100°C. Key electrical parameters include a test frequency of 10 kHz and a tolerance of -30% to +50%. Specific inductance and DC resistance values vary by suffix (e.g., RN114-1-02-15M has 15 mH inductance and 370 mΩ DCR; RN114-1-02-6M8 has 6.8 mH inductance).
Feature Summary
- Provides electromagnetic interference (EMI) noise suppression through current-compensated filtering.
- Designed for vertical or horizontal PCB mounting via through-hole technology.
- Constructed with ferrite core material for effective common mode choke performance.
Applications
- Electronic circuit noise suppression
- Electromagnetic interference (EMI) reduction in power lines
Procurement Notes
Verify the complete part number including the final alphanumeric suffix (e.g., -15M, -6M8), as this determines critical electrical specifications such as inductance value and DC resistance. Confirm that the required current rating aligns with the specific variant selected. Ensure the through-hole footprint dimensions match the target PCB layout before ordering.
Selection Notes
Select variants based on the specific inductance requirement for the target noise frequency at 10 kHz. Consider the maximum DC current rating to prevent saturation. Verify physical dimensions, as the RN114 series includes both vertical and horizontal orientation options. Ensure the operating temperature range meets the environmental conditions of the application.
Part Context
This component belongs to the Schaffner RN series of common mode chokes. These are current-compensated filters intended for power line applications. The series offers various inductance and current ratings to suit different EMI suppression needs across industrial and commercial electronics.
Replacement Considerations
Substitutes must match the RN series form factor and electrical characteristics. Potential alternatives include other Schaffner RN models with compatible inductance and current ratings. Cross-reference specific suffixes to ensure equivalent DCR and impedance profiles.
