Procurement Notes

Verify the specific manufacturer designation, as sources list both Bel Signal Transformer and Signal Transformer Inc. Confirm the package type and reel quantity requirements against your assembly line specifications. Ensure the operating temperature range meets your environmental constraints. Cross-reference the impedance tolerance and DC resistance values with your circuit design parameters before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring robust common mode noise attenuation for high-speed data lines carrying moderate currents. The 1.4 kOhm impedance offers significant filtering at 100 MHz. Consider the 1.5 A current rating to ensure adequate headroom for power delivery or signal integrity. The SMD footprint facilitates automated assembly in compact electronic devices.

Part Context

This part belongs to the SPDL series of ultra-compact chokes manufactured by Signal Transformer. The series includes various impedance and current ratings tailored for different signal integrity needs. The SPDL485025-1400-2P-T specifically targets applications demanding high current capacity alongside strong high-frequency noise suppression capabilities in a small form factor.

Replacement Considerations

SPDL3216-601-2P-T: Lower current (300 mA), lower impedance (600 Ohms). SPDL151306-400-2P-T: Significantly lower current (10 mA), lower impedance (400 Ohms). SPDL975WM-750-2P-T: Higher current (4 A), lower impedance (750 Ohms). Verify physical dimensions and electrical parameters match your design requirements.
