Overview
The BX8213LNLT is a surface-mount common mode choke from Pulse Electronics, designed for ADSL and VDSL applications. It features four lines with an inductance of 9000 µH (9 mH) per winding and a 1:1 turns ratio. The component operates within a temperature range of -40°C to +85°C and supports an isolation voltage of 500 Vrms. Its physical dimensions are 12.00 mm in length, 11.68 mm in width, and a maximum height of 8.76 mm. The device utilizes a vertical, 8-flat lead package and weighs approximately 2.0 grams.
Feature Summary
- Designed specifically for high-frequency DSL applications including ADSL and VDSL
- Surface mount construction with a vertical 8-flat lead package
- Provides common mode noise filtering for multi-line circuits
Applications
- ADSL line protection
- VDSL signal filtering
- High frequency DSL circuit noise suppression
Procurement Notes
Verify the specific suffix configuration when ordering, as packaging varies by designation. Confirm that the requested part number includes the 'T' suffix if tape and reel delivery is required, as standard shipments may utilize tray packaging. Ensure compatibility with the intended surface mount assembly process and verify compliance requirements such as RoHS-5 or RoHS-6 status against current project specifications before finalizing procurement.
Selection Notes
Select this component for designs requiring robust common mode rejection in digital subscriber line interfaces. The four-line configuration suits multi-pair transmission scenarios. Evaluate the 9 mH inductance value against the target frequency spectrum to ensure adequate attenuation. Consider the 500 Vrms isolation rating for safety compliance. Verify that the 12.00 mm x 11.68 mm footprint fits within the available PCB area constraints.
Part Context
This component belongs to the BX8213 series of common mode chokes manufactured by Pulse Electronics Network. The series is engineered for telecommunications infrastructure, focusing on signal integrity in broadband access networks. Variations within the series typically differ by packaging style or specific inductance tolerances, but all share the core design intent for DSL environment reliability.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source documentation. Cross-referencing requires matching electrical parameters such as 9000 µH inductance, four-line configuration, and compatible package dimensions.
