Overview
The ITG Electronics C301313A-302NHF is a two-line common mode choke designed for through-hole mounting. It features an inductance of 3 mH measured at 10 kHz and supports a current rating of 4.5 A. The component has a DC resistance (DCR) of 47 mOhm. This power line filter is part of the C301313A series, offering lead-free construction and RoHS compliance for integration into electronic circuits requiring electromagnetic interference suppression.
Feature Summary
- Two-line configuration for differential noise filtering
- Through-hole mounting for secure PCB attachment
- Lead-free and RoHS compliant construction
Applications
- Power line filtering
- Electromagnetic interference suppression
- Signal integrity enhancement in electronic circuits
Procurement Notes
Verify the specific suffix 'NHF' confirms lead-free status and RoHS compliance as indicated in manufacturer documentation. Confirm the package type matches through-hole requirements for your assembly process. Ensure the 4.5 A current rating meets your circuit's operational demands to prevent saturation or excessive heating during procurement validation.
Selection Notes
Select this component when a 3 mH inductance at 10 kHz is required for common mode noise reduction. The 4.5 A current handling capacity suits applications with moderate power loads. Verify that the through-hole form factor aligns with your board layout constraints and that the low DCR minimizes voltage drop across the filter in your specific design.
Part Context
This component belongs to the C301313A series from ITG Electronics, which includes various inductance values such as 5.0 mH variants. The series provides DIP-style common mode chokes for power line applications. The C301313A-302NHF specifically offers a balance of inductance and current capacity within this lineup.
Replacement Considerations
Check for other parts in the C301313A series with similar inductance and current ratings. Verify pin compatibility and physical dimensions before substituting. Ensure any alternative maintains the same through-hole mounting style and electrical specifications for direct replacement.
