Overview
The TLF14CB4721R0K1 is a leaded common mode choke coil manufactured by Taiyo Yuden, designed for AC line applications. It features a minimum common mode inductance of 4700 µH (4.7 mH) measured at 1 kHz. The component has a maximum DC resistance of 0.38 Ω and supports a rated current of 1 A. Its physical dimensions are 17.0 mm x 22.0 mm x 23.0 mm. It operates within a temperature range of -25 °C to +105 °C and withstands a high potential voltage of 2000 V with a minimum insulation resistance of 100 MΩ.
Feature Summary
- Provides effective electromagnetic interference suppression for single-phase AC lines through high common mode inductance.
- Constructed with leaded terminals for reliable through-hole mounting on printed circuit boards.
- Engineered to maintain performance across a wide operating temperature range from -25 °C to +105 °C.
Applications
- Single-phase EMI filtering for AC power inputs
- Noise suppression in household appliances
- Electromagnetic compatibility enhancement in industrial control equipment
Procurement Notes
Verify the complete part number including suffixes against official Taiyo Yuden documentation to ensure correct specifications. Confirm availability status as distribution data may vary. Check for RoHS compliance markings if required by specific regulatory standards. Ensure handling procedures account for through-hole mounting requirements and thermal limits during assembly.
Selection Notes
Select this component when a high inductance value of 4700 µH is required for common mode noise reduction in AC circuits. Consider the 1 A current rating and 0.38 Ω DC resistance for power loss calculations. Evaluate the through-hole package size against available PCB real estate. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
This component belongs to the TLF series of common mode chokes from Taiyo Yuden. The series is specifically designed for AC line filtering applications. The TLF14CB4721R0K1 variant offers higher inductance compared to lower-numbered models in the same family, making it suitable for stricter EMI requirements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Taiyo Yuden technical support or authorized distributors for verified cross-references based on specific electrical and mechanical constraints.
