Feature Summary
- Designed specifically for VDSL signal transmission environments
- Provides precise impedance matching via 100 Ohm primary winding
- Utilizes through-hole termination for robust mechanical stability
Applications
- VDSL modem input/output stages
- Digital subscriber line interface circuits
- Telecommunications signal conditioning modules
Procurement Notes
Verify the exact datasheet revision to confirm pinout compatibility with existing board layouts. Ensure the manufacturer confirms current production status as legacy components may face discontinuation. Cross-reference the 190uH inductance tolerance against system requirements before finalizing procurement orders.
Selection Notes
Select this component when designing VDSL interfaces requiring a 100 Ohm primary impedance. The through-hole package is suitable for high-reliability applications where surface mount alternatives are unsuitable. Confirm that the 190uH inductance value aligns with the target frequency band specifications for the intended digital subscriber line application.
Part Context
This part belongs to Pulse Electronics' audio and signal transformer portfolio, specifically targeting broadband access technologies. It serves as a critical interface component between the DSL transceiver and the telephone line, facilitating signal integrity over copper infrastructure.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with any alternative transformers by matching the 190uH inductance and 100 Ohm impedance specifications precisely.
