Overview
The C301306H-731N is a two-line common mode choke manufactured by ITG Electronics, Inc., designed for through-hole mounting. It features an inductance of 730 µH measured at 100 kHz and supports a current rating of 35A. The component exhibits a direct current resistance (DCR) of 3.4 mOhm. It operates within a temperature range of -40°C to +125°C and meets UL 94 V-0 material standards with RoHS compliance.
Feature Summary
- Through-hole toroidal construction for secure PCB insertion
- High current handling capability up to 35A
- Low direct current resistance for efficient power transmission
- RoHS compliant and UL 94 V-0 rated materials
Applications
- Switch-mode power supply input filtering
- Common mode noise suppression in AC/DC converters
- EMI reduction in high-current DC lines
Procurement Notes
Verify the specific suffix 'N' against the manufacturer's latest datasheet to confirm pinout and tolerance specifications. Confirm that the 35A current rating aligns with your thermal management design, as self-heating may affect performance. Ensure the through-hole footprint matches your PCB layout constraints before ordering.
Selection Notes
Select this component when high current capacity is required alongside moderate common mode inductance. The low DCR minimizes power loss compared to higher resistance alternatives. Consider the operating temperature range if the application involves extreme environmental conditions or significant self-heating from continuous high current loads.
Part Context
This part belongs to the C301306H series of common mode chokes from ITG Electronics. The series offers various inductance values while maintaining consistent physical dimensions and current handling capabilities. It is engineered for robust performance in industrial and commercial power electronics applications requiring reliable EMI suppression.
Replacement Considerations
Consult ITG Electronics for direct cross-references. Verify that any substitute maintains the 35A current rating and similar inductance value to ensure circuit compatibility.
