Overview
The Schaffner RN142-0.5-02 is a current-compensated common mode choke designed for PCB mounting via through-hole technology. It features an inductance of 82 mH and supports a maximum DC current of 500 mA with a typical DC resistance of 2.7 Ohms. The component operates within a frequency range of 0 Hz to 400 Hz and functions reliably across temperatures from -40°C to +100°C. Constructed with ferrite core material, it provides effective electromagnetic interference suppression in dual-line configurations.
Feature Summary
- Current-compensated design for efficient noise attenuation
- Ferrite core construction for stable magnetic performance
- Through-hole PCB mounting for secure mechanical attachment
Applications
- Electromagnetic interference filtering in power supply circuits
- Common mode noise suppression in electronic equipment
- Signal integrity enhancement in low-current applications
Procurement Notes
Verify the specific suffix designation against official datasheets, as variations such as -82M may indicate distinct electrical tolerances or testing frequencies. Confirm RoHS compliance status and lead-free requirements with the manufacturer prior to ordering. Ensure the selected variant matches the required inductance value and current rating for the target application circuit.
Selection Notes
Select this component when a high-inductance common mode choke is required for low-current signals. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +100°C range. Consider the physical dimensions and pin spacing for adequate PCB layout clearance. Verify that the 500 mA current rating exceeds the maximum expected load current under all operating conditions.
Part Context
This component belongs to the RN series of current-compensated chokes manufactured by Schaffner EMC Inc., now part of TE Connectivity. These devices are engineered for compact PCB integration where space constraints limit the use of larger filter assemblies. The series offers standardized form factors suitable for automated assembly processes in consumer and industrial electronics manufacturing.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific model are not available in the provided documentation. Cross-referencing requires matching inductance, current rating, and package type with alternative manufacturers' catalogs.
