UF1717V-300Y1R2-03

Overview

The UF1717V-300Y1R2-03 is a vertical through-hole common mode choke manufactured by TDK Corporation. It features a 30 µH inductance rating measured at 1 kHz and supports a current capacity of 1.2 A. The component utilizes a two-line configuration with four PC pins for mounting. Its direct current resistance (DCR) is specified at 150 mΩ. This filter is designed for electromagnetic interference suppression in electronic circuits requiring reliable signal integrity.

Feature Summary

• Vertical through-hole construction for secure board mounting
• Two-line common mode filtering capability
• Low direct current resistance for efficient power transmission

Applications

• Electromagnetic interference suppression in consumer electronics
• Signal integrity protection in data lines
• Power supply input filtering for small form factor devices

Procurement Notes

Verify the complete part number including suffixes to ensure correct pin configuration and inductance tolerance. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as availability varies. Request official datasheets to validate electrical parameters against specific design requirements before finalizing procurement decisions.

Selection Notes

Select this component when vertical mounting space is available and through-hole technology is preferred for mechanical stability. Ensure the 1.2 A current rating meets the circuit's maximum load requirements. Verify that the 30 µH inductance value provides sufficient attenuation for the target noise frequencies without causing excessive voltage drop across the low DCR windings.

Part Context

This component belongs to TDK Corporation's line of common mode chokes designed for EMI filtering. These components are typically used in applications where differential mode signals must be preserved while common mode noise is attenuated. The vertical package style allows for compact integration into printed circuit boards with limited surface area constraints.

Replacement Considerations

Consult official TDK substitution guides for verified alternatives. Ensure any replacement maintains identical inductance, current rating, and physical footprint dimensions to guarantee compatibility with existing PCB layouts and thermal management systems.
