TLF9UAH103WR23K1

Overview

The TLF9UAH103WR23K1 is a through-hole common mode choke coil manufactured by Taiyo Yuden. It features an inductance of 10 mH at 1 kHz and supports a maximum current rating of 230 mA. The component has a maximum DC resistance of 4.5 Ohms and an AC voltage rating of 250 V. Its physical dimensions are 17 mm in length, 11 mm in width, and 12 mm in height, utilizing a PC pin-4 vertical package.

Feature Summary

• Designed for suppression of common mode noise on AC power lines
• Utilizes a vertical through-hole mounting configuration for PCB integration
• Constructed with dual winding capability for two-line applications

Applications

• AC line filtering in consumer electronics
• Noise suppression in household appliances
• Power supply input stages for EMI reduction

Procurement Notes

Verify the specific suffix and packaging type when ordering, as bulk quantities may vary. Confirm that the 230 mA current rating meets the circuit requirements to prevent saturation. Ensure the 250 V AC rating aligns with the local mains voltage standards. Check for RoHS compliance documentation if required by regional regulations.

Selection Notes

Select this component for applications requiring moderate inductance values in a compact vertical footprint. The 4.5 Ohm DCR is suitable for low-current circuits. Consider the 12 mm height constraint during mechanical design. Compare against similar TLF series parts if higher current or different inductance is needed.

Part Context

This part belongs to the TLF series of leaded common mode chokes from Taiyo Yuden. These components are specifically engineered for AC line filtering applications. The series offers various inductance and current ratings to suit different power levels while maintaining a standardized form factor for easy PCB layout.

Replacement Considerations

Direct substitutes include other Taiyo Yuden TLF series parts with matching 10 mH inductance and 230 mA rating. Verify pin compatibility and dimensional constraints before replacing. Cross-reference with equivalent models from other manufacturers ensuring identical electrical specifications.
