Overview
The Schaffner EV35-2.0-02-20M is a vertical through-hole common mode choke designed for electromagnetic interference suppression. It features a nominal inductance of 20 mH at 100 kHz and supports a maximum rated current of 2 A. The component operates within a temperature range of -40°C to +100°C and utilizes a two-line configuration with four pins for mounting.
Feature Summary
- Provides compact common mode noise suppression for differential signal lines
- Vertical leaded construction facilitates standard printed circuit board assembly
- Engineered for stable performance across wide industrial temperature ranges
Applications
- Power supply input filtering
- Battery charger circuits
- Portable electronic device protection
- Energy-efficient system noise reduction
Procurement Notes
Verify the specific inductance tolerance and DC resistance values against the official manufacturer datasheet before integration. Confirm that the vertical pin spacing matches the target PCB footprint requirements. Ensure the selected variant meets all necessary safety certifications for the intended end-use environment.
Selection Notes
Select this component when a 20 mH common mode inductance is required for low-current applications up to 2 A. The vertical form factor is suitable for space-constrained boards where height is less critical than profile. Evaluate thermal management needs given the operating temperature limits and self-heating characteristics under load.
Part Context
This part belongs to the EV35 series of common mode chokes from Schaffner EMC Inc. The series offers various inductance and current ratings in both horizontal and vertical configurations. It serves as a fundamental passive component for EMI mitigation in AC/DC conversion stages and sensitive digital logic interfaces.
Replacement Considerations
The EH35-3.0-02-10M is listed as an alternative, though it differs in orientation and electrical specifications. Verify compatibility with existing footprints and circuit parameters before substitution.
