Overview
The Schaffner RN214-2.5-02-3M3 is a common mode choke filter designed for electromagnetic interference suppression. It features a vertical through-hole mounting style with a ferrite core and unshielded construction. The component supports a maximum DC current of 2.5 A and provides an inductance of 3.3 mH with a tolerance range of -30% to +50%. Its maximum DC resistance is 102 mOhms, tested at a frequency of 10 kHz. The unit operates within a temperature range of -40°C to +100°C and measures 18 mm x 12.5 mm x 20 mm.
Feature Summary
- Provides common mode current-compensated inductance using two windings over a ferrite ring core.
- Designed for compact PCB mounting with vertical orientation and through-hole termination.
- Utilizes ferrite core material for effective EMI interference suppression.
Applications
- General electronic equipment requiring common mode noise reduction
- Power supply input filtering stages
- Signal line protection against electromagnetic interference
Procurement Notes
Verify the specific part number RN214-2.5-02-3M3 against official TE Connectivity/Schaffner documentation to confirm pinout, tolerance, and thermal ratings. Ensure compatibility with existing PCB footprint dimensions of 18 mm x 12.5 mm x 20 mm. Cross-reference manufacturer datasheets for RoHS compliance status and operating temperature limits before integration into final designs.
Selection Notes
Select this component when a 2.5 A rated common mode choke with 3.3 mH inductance is required for vertical PCB mounting. Consider the -30% to +50% inductance tolerance and 102 mOhm DC resistance for circuit design margins. Verify that the -40°C to +100°C operating range meets environmental requirements and that the unshielded design does not interfere with nearby sensitive components.
Part Context
This component belongs to the Schaffner RN series of chokes, which are characterized as compact common-mode current-compensated chokes. These devices are engineered to suppress EMI interference in electronic circuits. The RN series typically utilizes ferrite cores and offers various current ratings, positioning these chokes as standard solutions for noise filtration in power and signal lines across industrial and consumer applications.
