Overview
The SPDL4532-220-2P-T is a two-line surface mount common mode choke manufactured by Signal Transformer. It features an inductance of 22 µH at 100 kHz and provides an impedance of 1.2 kOhms at 10 MHz. The component supports a maximum DC current of 310 mA with a maximum DC resistance of 1 Ohm. Designed for PCB mounting, it operates within a temperature range of -40°C to +125°C.
Feature Summary
- Provides effective noise suppression for high-speed signal transmission lines through common mode filtering.
Applications
- Automotive infotainment systems
- Multimedia applications
- High-speed signal transmission lines
Procurement Notes
Verify the manufacturer designation as Signal Transformer or Bel Signal Transformer, as both names appear in public listings. Confirm the package type is SMD/SMT and the specific electrical parameters match the 22 µH inductance and 310 mA current rating. Ensure the operating temperature range covers the required -40°C to +125°C specification for the target application environment.
Selection Notes
Select this component when space-constrained designs require a compact common mode choke for automotive or multimedia circuits. The 4532 metric footprint suits dense PCB layouts. Verify that the 310 mA saturation current meets the circuit's peak requirements and that the 1.2 kOhm impedance at 10 MHz aligns with the targeted noise frequencies.
Part Context
This part belongs to the SPDL series of ultra-compact chokes designed for noise suppression. It utilizes ferrite core material and is unshielded. The series is specifically engineered for automotive and high-speed data applications where small form factors are critical.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official distributor databases for cross-references based on identical inductance, impedance, and current ratings.
