SPDL975WM-2500-2P-T

Overview

The SPDL975WM-2500-2P-T is a two-line surface mount common mode choke from the SPDL Series II by Signal Transformer. It features an impedance of 2,500 ohms at 100 MHz and a maximum DC current rating of 1.9 mA. The component has a maximum DC resistance of 70 ohms and operates within a temperature range of -40°C to +125°C. Its physical dimensions are 12.5 mm in length, 7 mm in width, and 5 mm in height. The device is supplied in tape and reel packaging for automated assembly.

Feature Summary

• Two-line configuration for differential noise suppression
• High impedance performance at 100 MHz
• Compact surface mount footprint

Applications

• Noise suppression in high-frequency signal lines
• EMI filtering in compact electronic assemblies
• Common mode interference reduction in data interfaces

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 1.9 mA current limit meets the circuit requirements. Ensure the surface mount package dimensions fit the PCB layout constraints. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when high impedance at 100 MHz is required for common mode noise. Consider the low current rating of 1.9 mA for signal line applications rather than power lines. Evaluate the 70 ohm DC resistance impact on signal integrity. Compare physical size against available board space.

Part Context

This part belongs to the SPDL Series II, designed for surface mount applications. It is manufactured by Signal Transformer, now part of Bel Fuse. The series focuses on compact common mode chokes for EMI suppression in dense PCB layouts.

Replacement Considerations

Check for direct substitutes with identical 2,500 ohm impedance and 1.9 mA current ratings. Verify pin compatibility and mechanical dimensions for drop-in replacement. Consult manufacturer cross-reference lists for verified alternatives.
