- High current handling capability suitable for power line filtering
- Ferrite core construction for effective noise suppression
Applications
- Automotive infotainment systems
- High-speed signal transmission lines
- Noise suppression in compact electronic devices
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official datasheet before integration. Confirm that the surface mount footprint dimensions align with the target PCB land pattern. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check RoHS compliance status if required by regional regulations.
Selection Notes
Select this component when high current capacity is required alongside moderate impedance levels in a small form factor. Compare the 6 A rating against circuit load requirements to prevent saturation. Evaluate the 225 Ohm impedance at 100 MHz against the target noise frequency spectrum. Consider the unshielded nature of the device for potential EMI interactions with nearby components.
Part Context
This part belongs to the SPDL series of ultra-compact chokes from Bel Signal Transformer. It is designed for surface mount technology applications requiring robust common mode noise reduction. The series offers various impedance and current ratings to suit different signal and power line filtering needs in automotive and industrial electronics.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains the 225 Ohm impedance at 100 MHz and the 6 A current rating. Verify physical footprint compatibility to avoid PCB redesign.
