Overview
The ALFT-03A-1 is a common mode filter choke manufactured by Abracon LLC. It features a radial termination style and is designed for PCB mount applications. The component has an inductance of 105 uH and supports a maximum DC current of 200 mA. Its maximum DC resistance is specified at 400 mohms. The operating temperature range extends from -25 C to +85 C.
Feature Summary
- Provides common mode noise filtering for single-channel circuits
- Utilizes ferrite core material for effective electromagnetic interference suppression
- Designed for through-hole mounting on printed circuit boards
Applications
- Power supply input filtering
- Signal line noise reduction
- Electromagnetic compatibility enhancement in electronic devices
Procurement Notes
Verify the specific part number suffix to ensure correct inductance and current ratings, as variations exist within the ALFT series. Confirm package dimensions and lead form against your PCB footprint requirements. Check datasheet specifications for thermal derating curves if operating near maximum temperature limits. Ensure supplier documentation matches the manufacturer's official release.
Selection Notes
Select this component when a low-inductance common mode choke is required for high-frequency noise suppression. The 105 uH value suits applications where minimal impedance to differential signals is necessary while attenuating common mode noise. Consider the 200 mA current rating to ensure adequate headroom for the target circuit's operational current without saturation.
Part Context
This component belongs to the ALFT series of common mode chokes from Abracon. The series offers various inductance values and current ratings to suit different filtering needs. The ALFT-03A-1 specifically targets applications requiring moderate inductance with compact radial packaging for space-constrained designs.
Replacement Considerations
Cross-reference with other ALFT series parts like ALFT-03A-6 or ALFT-03A-9 for similar form factors but verify inductance differences. Ensure substitute components match the 200 mA current rating and 400 mohm resistance limits to maintain circuit performance.
