Overview
The ALFT-04-3 is a common mode filter choke manufactured by Abracon LLC, designed for through-hole PCB mounting. It features a single-channel configuration with an inductance of 500 uH measured at a test frequency of 1 kHz and a tolerance of 20%. The component supports a maximum DC current of 6.0 A and exhibits a maximum DC resistance of 7.0 mOhms. It operates within a temperature range of -40°C to +125°C. Physical dimensions are 34 mm in length, 18 mm in width, and 41 mm in height, utilizing radial termination.
Feature Summary
- Provides common mode noise suppression via high inductance characteristics
- Supports high current handling capability up to 6 A
- Utilizes radial through-hole termination for standard PCB integration
Applications
- Power supply input filtering
- EMI suppression in electronic circuits
- Signal line protection against common mode interference
Procurement Notes
Verify the obsolete status and end-of-life notification dated July 9, 2025, before procurement planning. Availability is restricted or discontinued across major distributors. Confirm alternative sourcing channels or substitute components due to limited stock conditions and potential supply chain constraints associated with this discontinued part number.
Selection Notes
Select this component only if its specific 500 uH inductance and 6 A current rating align with circuit requirements. Ensure the physical footprint of 34x18x41 mm fits the design constraints. Verify that the operating temperature range of -40°C to +125°C meets environmental specifications. Consider the radial lead style compatibility with existing board layouts.
Part Context
This component belongs to the ALFT series of common mode chokes from Abracon LLC. It falls under the category of inductors, chokes, and coils. The product is classified as a standard choke type intended for general-purpose applications requiring common mode noise filtration in electronic systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers must identify equivalent components based on matching electrical parameters such as inductance, current rating, and DC resistance.
