Overview
The Schaffner RN116-0.8-02-27M is a horizontal through-hole common mode filter choke designed for PCB mounting. It features an inductance of 27 mH with a tolerance range of -30% to +50%. The component supports a maximum DC current of 800 mA and exhibits a maximum DC resistance of 370 mOhms. It operates within a temperature range of -40°C to +100°C. The physical package dimensions are specified as 21.5 mm x 22.5 mm x 13.2 mm, utilizing a ferrite core material.
Feature Summary
- Horizontal surface-mount compatible design for efficient PCB layout integration
- Current compensated choke construction for effective noise suppression
- Ferrite core material ensuring stable magnetic performance
Applications
- Power line filtering in electronic equipment
- Common mode noise reduction in AC/DC power supplies
- Electromagnetic compatibility (EMC) mitigation in consumer electronics
Procurement Notes
Verify the specific manufacturer part number against official TE Connectivity or Schaffner documentation to confirm electrical parameters and mechanical footprint. Ensure the procurement source provides valid RoHS compliance data and original manufacturer traceability. Cross-reference the 370 mOhm DC resistance and 27 mH inductance values with the latest datasheet to avoid counterfeit or obsolete stock issues during acquisition.
Selection Notes
Select this component when a horizontal form factor is required for space-constrained PCB designs. The 800 mA current rating suits low-power applications, while the 27 mH inductance provides significant attenuation for common mode interference. Verify that the operating environment remains within the -40°C to +100°C thermal limits and that the through-hole termination style matches the target board assembly process.
Part Context
This component belongs to the RN series of common mode chokes manufactured by Schaffner EMC Inc., now part of TE Connectivity. The RN series is engineered for general-purpose electromagnetic interference suppression in various electronic systems. The specific model utilizes a horizontal winding configuration to optimize board space utilization compared to vertical alternatives.
Replacement Considerations
The RN116-0.5-02-27M is a related variant within the same series but differs in current handling capacity. Substitution requires verification of the lower current rating suitability for the specific application circuit.
