Overview
The UT2020-003 is a common mode choke manufactured by Triad Magnetics, designed for switch-mode and high-frequency applications. It features an inductance of 2.5 mH at 10 kHz with a current rating of 700 mA (0.7 A). The component utilizes a through-hole mounting style and has a DC resistance of 400 mOhm. Its physical height is specified as 22 mm.
Feature Summary
- Provides common mode noise filtering for two-line circuits
- Engineered for switch-mode and high-frequency operation
- Utilizes through-hole termination for board integration
Applications
- Switch-mode power supply input filtering
- High-frequency circuit noise suppression
- Two-line signal integrity protection
Procurement Notes
Verify the specific inductance tolerance and saturation current requirements against the official Triad Magnetics datasheet before procurement. Confirm that the 400 mOhm DC resistance aligns with thermal management constraints in the target design. Ensure the through-hole footprint dimensions match the PCB layout specifications to guarantee proper mechanical fit and electrical connectivity during assembly.
Selection Notes
Select this component when designing circuits requiring 2.5 mH common mode inductance at 700 mA. Consider the 22 mm height constraint for enclosure clearance. Evaluate the 400 mOhm DCR impact on voltage drop and power dissipation relative to the system's efficiency targets. Ensure compatibility with standard through-hole assembly processes.
Part Context
This part belongs to the common mode chokes category from Triad Magnetics. It serves as a passive filter component to suppress electromagnetic interference in dual-line configurations. The device is distinct from power transformers or inductors used for energy storage, focusing solely on noise attenuation in high-frequency environments.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement matches the 2.5 mH inductance, 700 mA current rating, and 400 mOhm DC resistance. Verify mechanical compatibility including the 22 mm height and through-hole pin configuration.
