Overview
The TF1821VU-103Y1R0-01 is a two-line common mode choke coil designed for AC power line filtering. It features a through-hole mounting configuration with a maximum rated current of 1A and a maximum DC resistance (DCR) of 1.0 ohm. The component belongs to the TF series manufactured by TDK Corporation.
Feature Summary
- Provides common mode noise suppression for AC power lines
- Supports through-hole installation for robust mechanical attachment
Applications
- AC power line filtering in electronic equipment
- EMI suppression for single-phase AC inputs
Procurement Notes
Verify component authenticity against official TDK documentation due to discontinued status. Confirm that the 1A current rating and 1.0 ohm DCR meet specific circuit requirements. Ensure through-hole footprint compatibility with existing PCB layouts before integration.
Selection Notes
Select this component for applications requiring through-hole common mode chokes with a 1A current capacity. Verify that the 1.0 ohm DC resistance does not cause excessive voltage drop in the target power supply design compared to lower resistance alternatives.
Part Context
This part is part of the TF series of common mode choke coils intended for AC power line applications. It serves as an EMI filter component to suppress electromagnetic interference on AC mains inputs within consumer or industrial electronics.
Replacement Considerations
Official substitute part numbers are not confirmed in available public documentation. Evaluate alternative through-hole common mode chokes from TDK or other manufacturers based on matching 1A current ratings, similar DCR values, and compatible physical dimensions.
