Overview
The Schaffner EV35-3.0-02-10M is a dual common mode choke designed for horizontal through-hole mounting. It features a nominal inductance of 10mH at 10kHz with a maximum DC resistance of 53mOhm and a rated current of 4A. The component utilizes a four-pin configuration and operates within a temperature range of -40°C to +125°C. Its compact vertical or horizontal form factor supports efficient PCB integration for electromagnetic interference suppression in power supply circuits.
Feature Summary
- Dual winding configuration for effective common mode noise attenuation
- Low DC resistance minimizes power loss in the signal path
- Robust thermal stability ensures reliable operation under varying load conditions
Applications
- Power supply input filtering
- Battery charger circuits
- Portable electronic devices
- Energy-efficient system interfaces
Procurement Notes
Verify the specific pin pitch and mounting orientation requirements against your PCB layout before ordering. Confirm that the 4A current rating and 10mH inductance meet your circuit's EMI suppression needs. Ensure compatibility with automated assembly processes if high-volume production is planned. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when dual-channel common mode filtering is required for low-current applications. The 10mH value provides significant attenuation for high-frequency noise while maintaining low insertion loss. Consider the physical dimensions and lead spacing to ensure proper fit within the enclosure. Evaluate the thermal performance to guarantee longevity in enclosed spaces.
Part Context
This component belongs to Schaffner's EV series of common mode chokes, which are engineered for general-purpose EMI suppression. The series offers various inductance values and current ratings to suit different power levels. The EV35 model specifically targets compact designs requiring robust noise filtering in space-constrained environments.
Replacement Considerations
EV35-3.0-02-20M is a documented alternative with higher inductance. Verify electrical parameters and mechanical footprint compatibility before substitution. Ensure the replacement meets all original design specifications for current handling and noise attenuation.
