SPDL485025-1000-2P-T

Overview

The SPDL485025-1000-2P-T is a two-line surface mount common mode choke from the Signal Transformer series. It exhibits an impedance of 1 kOhms at a test frequency of 100 MHz and supports a maximum DC current of 2 A. The component features a typical DC resistance of 24 mOhms. Its physical dimensions are 4.8 mm in length, 5.0 mm in width, and 2.5 mm in height. Designed for PCB mounting, it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides noise suppression through high impedance characteristics at 100 MHz
• Supports high current handling capability of 2 A with low DC resistance
• Utilizes a compact surface mount package suitable for space-constrained designs

Applications

• High speed signal transmission lines
• Automotive infotainment systems
• Multimedia interfaces

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the manufacturer's official datasheet prior to integration. Confirm that the operating temperature range meets the environmental requirements of the target application. Ensure the surface mount footprint matches the design layout specifications exactly to prevent assembly issues.

Selection Notes

Select this component when a balance between high current capacity and significant noise attenuation at 100 MHz is required. The low DC resistance minimizes power loss in the signal path. Consider the physical dimensions to ensure compatibility with the available PCB real estate and mounting constraints.

Part Context

This part belongs to the SPDL series of ultra-compact chokes manufactured by Bel Signal Transformer. The series is characterized by small form factors designed for modern electronic applications requiring efficient noise filtering without occupying excessive board space.

Replacement Considerations

Consult the manufacturer's cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains identical impedance, current rating, and physical dimensions.
