Overview
The SPDL485025-350-2P-T is a two-line surface mount common mode choke from the SPDL series by Signal Transformer. It features an impedance of 350 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 4 A with a typical DC resistance of 28 mOhms. The component utilizes ferrite core material and operates within a temperature range of -40°C to +125°C. Its physical dimensions are 4.8 mm in length, 5.0 mm in width, and 2.5 mm in height, packaged in reels for automated assembly.
Feature Summary
- Provides noise suppression for high-speed signal transmission lines through common mode filtering
- Designed for ultra-compact PCB mounting with surface mount termination
- Utilizes ferrite core construction for effective electromagnetic interference mitigation
Applications
- Automotive infotainment systems
- Multimedia interface circuits
- High-speed data bus protection
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the manufacturer's latest datasheet before integration. Confirm that the reel packaging quantity aligns with production requirements. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the footprint dimensions with the PCB design library to guarantee mechanical compatibility.
Selection Notes
Select this component when a compact form factor is required for automotive or multimedia applications. The 4 A current rating suits power line filtering where space is constrained. Compare the 350 Ohm impedance at 100 MHz against target noise frequencies to ensure adequate attenuation. Evaluate the low DC resistance to minimize voltage drop in sensitive signal paths.
