Overview
The TLF14CB2230R4K1 is a leaded common mode choke coil designed for AC line applications, manufactured by Taiyo Yuden. It features a minimum common mode inductance of 22 mH and a maximum DC resistance of 1.7 Ω. The component supports a rated current of 0.4 A and operates within a temperature range of -25 °C to +105 °C. Its physical dimensions are 22.0 mm in length, 17.0 mm in width, and 23.0 mm in height. The device utilizes through-hole mounting and is compliant with RoHS standards.
Feature Summary
- Designed as a leaded common mode choke coil specifically for AC line filtering applications
- Provides high common mode inductance to suppress electromagnetic interference on power lines
- Constructed for through-hole PCB mounting to ensure secure mechanical attachment
Applications
- AC line filtering in electronic equipment
- Common mode noise suppression for power input circuits
- Electromagnetic interference reduction in single-phase power systems
Procurement Notes
Verify the discontinued status of this part number before initiating any procurement activities. Confirm that the specific electrical parameters, such as the 22 mH inductance and 0.4 A rated current, meet the design requirements. Ensure that the through-hole package dimensions are compatible with the target printed circuit board layout. Check for available replacement components if the original part is no longer in production.
Selection Notes
Select this component when designing circuits requiring robust common mode noise suppression for AC lines. The 22 mH inductance value is suitable for low-frequency interference attenuation. Consider the 0.4 A current rating to ensure the component does not saturate under normal operating conditions. Verify that the through-hole form factor aligns with the assembly process and board space constraints.
Part Context
This component belongs to the Taiyo Yuden family of passive filters and chokes. It is engineered for reliability in power supply inputs where common mode noise must be minimized. The leaded construction distinguishes it from surface-mount alternatives, offering different mechanical integration options for industrial and consumer electronics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers should evaluate alternative common mode chokes with matching inductance, current rating, and package dimensions.
