SPDL485025-500-2P-T

Overview

The SPDL485025-500-2P-T is a two-line surface mount common mode choke from the Signal Transformer series. It provides 500 Ohms impedance at 100 MHz with a maximum DC current rating of 4 A and a typical DC resistance of 19 mOhms. The component measures 48 mm in length, 50 mm in width, and 2.5 mm in height. It operates within a temperature range of -40°C to +125°C and is supplied in tape and reel packaging.

Feature Summary

• Designed for high-current noise suppression in multi-line signal paths
• Compact surface mount construction suitable for dense PCB layouts
• Ferrite core technology optimized for high-frequency interference attenuation

Applications

• Automotive infotainment systems
• High-speed data transmission lines
• Multimedia interface protection

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the manufacturer's latest datasheet before integration. Confirm that the physical footprint matches the target PCB design constraints. Ensure the operating temperature range aligns with the final assembly environment requirements.

Selection Notes

Select this component when high current handling capacity is required alongside effective common mode noise reduction. The low DC resistance minimizes power loss in power or high-current signal lines. Evaluate the physical dimensions to ensure compatibility with available board space and mounting orientation.

Part Context

This part belongs to the SPDL series of ultra-compact common mode chokes manufactured by Bel Signal Transformer. The series focuses on providing robust EMI filtering solutions for automotive and industrial applications where space is limited but performance standards are strict.

Replacement Considerations

Check for parts with identical 500 Ohm impedance at 100 MHz and a minimum 4 A current rating. Verify that substitute components match the 48x50x2.5 mm package dimensions and SMD termination style to maintain mechanical fit.
