This device serves as a signal filter within telecommunications infrastructure, providing common mode noise suppression for high-speed data lines.
Feature Summary
- Designed specifically for XDSL signal filtering applications
- Surface mount technology construction for automated assembly
- Provides common mode noise suppression for telecommunication lines
Applications
- XDSL line interface circuits
- Telecommunications equipment signal conditioning
- Common mode noise filtering in data transmission systems
Procurement Notes
Verify the specific datasheet revision and physical dimensions against the design schematic before integration. Confirm that the surface mount footprint matches the PCB layout requirements. Ensure the operating temperature range aligns with the environmental conditions of the final assembly. Check for any recent product change notifications that may affect material composition or performance characteristics.
Selection Notes
Select this component when designing XDSL interfaces requiring a 4700uH common mode choke with low DC resistance. Consider the surface mount package type for manufacturing compatibility. Evaluate the thermal performance and current handling capabilities relative to the specific circuit load. Compare alternative models from the same manufacturer if different inductance values or form factors are required for the application.
Part Context
This component belongs to the family of audio and signal transformers produced by Pulse Electronics. It falls under the subcategory of common mode chokes used in telecommunications. The product is distinct from general-purpose inductors due to its specific tuning for DSL frequency bands and common mode rejection requirements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing electrical parameters such as inductance, DC resistance, and impedance characteristics. Consult the manufacturer for updated recommendations if discontinuation occurs.
