UF1717H-342Y0R4-01

Overview

The UF1717H-342Y0R4-01 is a two-line common mode choke manufactured by TDK Corporation, designed for through-hole mounting. It features an inductance of 3.4 mH measured at 1 kHz and supports a maximum current rating of 400 mA. The component exhibits a direct current resistance (DCR) of 1.3 Ohms. This device is categorized under power line filters and is engineered to suppress electromagnetic interference in sensitive electronic circuits.

Feature Summary

Provides effective common mode noise suppression for two-line configurations
Engineered with low impedance characteristics suitable for sensitive circuit protection
Constructed for reliable through-hole integration into printed circuit boards

Applications

Power supply input filtering
Data processing equipment signal integrity maintenance
Consumer electronics noise reduction

Procurement Notes

Verify the complete part number including suffixes against official TDK documentation to ensure exact electrical specifications. Confirm that the required current rating and inductance values align with the design constraints. Check for any specific handling or storage requirements detailed in the manufacturer's datasheet before procurement.

Selection Notes

Select this component when a compact through-hole solution is required for two-line common mode noise attenuation. Ensure the operating current does not exceed 400 mA to maintain performance. Verify that the 1.3 Ohm DCR is acceptable for the specific voltage drop requirements of the target application circuit.

Part Context

This component belongs to the UF1717H series of common mode chokes from TDK Corporation. The series offers various inductance and current ratings tailored for different power line filtering needs. These components are widely utilized in industries requiring robust electromagnetic interference mitigation for compact electronic assemblies.

Replacement Considerations

Consult official TDK substitution guides for verified alternatives. Cross-reference inductance, current rating, and physical dimensions to ensure compatibility without modifying the existing board layout or circuit performance parameters.
