Overview
The SPDL121006-910-2P-T is a two-line surface mount common mode choke from the SPDL series by Signal Transformer. It features an impedance of 910 Ohms at 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 4.5 mA and has a maximum DC resistance of 23 Ohms. It operates within a temperature range of -40°C to +125°C. The device utilizes a ferrite core and is housed in an unshielded 1210 metric package measuring 3.2 mm x 2.5 mm x 1.6 mm.
Feature Summary
- Provides noise suppression for high-speed signal transmission lines
- Designed for automotive infotainment and multimedia applications
- Ultra-compact surface mount construction
Applications
- Automotive Infotainment Systems
- Multimedia Interfaces
- High Speed Signal Transmission Lines
Procurement Notes
Verify the manufacturer designation, as this part number appears under both Bel Signal Transformer and Signal Transformer branding in public records. Confirm RoHS compliance status and specific packaging quantities directly with authorized distributors or the manufacturer before procurement. Ensure the correct impedance value of 910 Ohms matches the design requirements.
Selection Notes
Select this component for circuits requiring common mode noise filtering on differential pairs where low current capacity is acceptable. The 4.5 mA rating limits suitability to signal-level lines rather than power delivery. Verify that the 23 Ohm DC resistance does not introduce excessive voltage drop or signal attenuation in the target application circuit.
Part Context
This component belongs to the SPDL series of ultra-compact common mode chokes. These devices are engineered for space-constrained PCB layouts, utilizing a small 1210 footprint. The series is characterized by ferrite core technology and is intended for EMI/RFI suppression in sensitive electronic environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching impedance, current rating, and physical dimensions.
