Overview
The SPDL2012-221-2P-T is a two-line surface mount common mode choke from the SPDL series by Signal Transformer. It features an impedance of 220 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 400 mOhms. It operates within a temperature range of -40°C to +125°C. The physical dimensions are 2.0 mm in length, 1.2 mm in width, and 1.2 mm in height, housed in a compact SMD package.
Feature Summary
- Provides noise suppression for two-line circuits via common mode filtering
- Designed for surface mount PCB integration
- Constructed as an ultra-compact wirewound choke
Applications
- Noise suppression in electronic circuits
- Signal integrity management in compact devices
Procurement Notes
Verify the specific manufacturer designation, as the model may be associated with Bel Signal Transformer or Signal Transformer depending on corporate structure history. Confirm RoHS compliance status and AEC-Q200 qualification if automotive application is required. Ensure the packaging format matches the reel specification provided in official documentation.
Selection Notes
Select this component when space-constrained designs require a two-line common mode filter with low profile. The 220 Ohm impedance at 100 MHz suits specific frequency attenuation needs. Verify that the 300 mA current rating meets the circuit's operational requirements and that the 400 mOhm DCR aligns with power loss constraints.
Part Context
This part belongs to the SPDL series of ultra-compact chokes manufactured by Signal Transformer (formerly Bel Signal Transformer). The series is characterized by small footprint dimensions suitable for dense PCB layouts. The product falls under the category of common mode filters and chokes within the broader inductors and coils classification.
Replacement Considerations
Consult official substitution guides for equivalent parts within the SPDL series or other Signal Transformer common mode chokes. Verify dimensional compatibility and electrical parameter alignment before replacing.
