Overview
The UT2020-001 is a common mode filter choke manufactured by Triad Magnetics, designed for switch-mode and high-frequency applications. It features an inductance of 9 mH with a maximum DC current rating of 500 mA. The component exhibits a maximum DC resistance of 1.4 Ohms. Its physical dimensions are 22 mm in length and 22 mm in width, with a height of 22 mm. This through-hole device is classified under common mode chokes and is suitable for PCB mounting in electronic circuits requiring noise suppression.
Feature Summary
- Provides common mode noise filtering for high-frequency circuits
- Designed for switch-mode power supply applications
- Utilizes a compact vertical PCB mount form factor
Applications
- Switch-mode power supplies
- High-frequency circuit noise suppression
- Common mode interference filtering
Procurement Notes
Verify the specific datasheet version to confirm mechanical tolerances and electrical characteristics prior to integration. Ensure compatibility with existing PCB footprints, as dimensions are critical for assembly. Confirm RoHS compliance status if required by project specifications. Cross-reference manufacturer part numbers to avoid substitution errors during procurement.
Selection Notes
Select this component when a 9 mH inductance is required for common mode rejection in space-constrained designs. The 500 mA current rating suits low-to-medium power signal lines. Consider the 22 mm height constraint for enclosure clearance. Evaluate the 1.4 Ohm DC resistance impact on circuit efficiency compared to alternative inductors.
Part Context
This component belongs to Triad Magnetics' line of common mode filter chokes. It is distinct from their power transformers and fixed inductors, focusing specifically on electromagnetic interference mitigation. The UT series typically targets applications requiring reliable noise reduction in compact electronic assemblies.
