Overview
The C201305A-173 is a nanocrystal common mode choke manufactured by ITG Electronics, Inc. It features an inductance of 17 mH measured at 10 kHz and supports a maximum current of 4 A. The component utilizes a through-hole mounting style with two lines. Its direct current resistance (DCR) is specified as 50 mOhm. The series offers compact dimensions with a maximum length and width of 23.00 mm and a maximum height of 25.00 mm.
Feature Summary
- Utilizes nanocrystal core material for high-performance filtering
- Designed for through-hole PCB insertion with fixed pin spacing
- Compact physical footprint suitable for space-constrained layouts
Applications
- Power line filtering
- Switch mode power supply EMI suppression
- Common mode noise reduction in electronic circuits
Procurement Notes
Verify the specific part number suffix to ensure correct inductance and current ratings. Confirm that the through-hole package dimensions match the target PCB footprint. Check for RoHS and HF compliance requirements if applicable to the end product. Ensure the operating temperature range meets system specifications.
Selection Notes
Select this component when a 17 mH inductance value is required for common mode noise attenuation. The 4 A current rating determines the thermal and electrical limits for the application. Consider the 50 mOhm DCR for voltage drop calculations. The through-hole format dictates the assembly method and board layout constraints.
Part Context
This component belongs to the C201305A series from ITG Electronics, which includes various inductance values ranging from 1.0 mH to 47.0 mH. The series shares a consistent DIP package design with varying current capacities and DC resistance values across different model numbers within the same family.
Replacement Considerations
Substitute parts must match the 17 mH inductance, 4 A current rating, and 50 mOhm DCR. Verify that the replacement also uses a through-hole package with compatible pin spacing. Ensure the substitute component maintains similar nanocrystal core characteristics for equivalent filtering performance.
