               [ Bob Smith Termination: 4x 75Ω Resistors + 1000pF/2kV to Shield ]

Engineering Design Notes:

1. Full Duplex 4-Pair Routing: Signals are balanced across four independent 1CT:1 transformers, providing full common-mode noise suppression with ≥30 dB rejection across 1 MHz to 100 MHz.
2. Integrated Bob Smith Circuit: The cable-side center taps tie through four 75 Ω balance resistors into a high-voltage 1000 pF/2 kV capacitor connected directly to the outer shield. This architecture drains ESD and common-mode transients without impacting differential data eye-diagrams.

Technical FAQs

Q1: Is LINK-PP LPJK0071AWNL a direct replacement for Bel Fuse 0826-1G1T-23-F?

Yes. LPJK0071AWNL is an exact pin-to-pin, footprint-compatible drop-in replacement for Bel Fuse 0826-1G1T-23-F. It shares the identical Gigabit 4-pair pin assignment (Pins 1–12), Tab-Up latch orientation, and Dual Green LED polarities (Right: 14+/13-, Left: 16+/15-), requiring zero schematic or PCB layout modifications.

Q2: Does the LPJK0071AWNL connector support PoE?

No. The LPJK0071AWNL is a Non-PoE Gigabit connector engineered strictly for standard Ethernet data transmission. For PoE applications, consider LINK-PP's LPJK1014A8NL (PoE 15.4W) or LPJK6003AONL (PoE+ 30W) series.

Q3: What is the benefit of the SUS 304 Stainless Steel shield on LPJK0071AWNL?

The 0.20 mm thick SUS 304-1/2H Stainless Steel shield provides significantly higher mechanical yield strength, superior spring retention on EMI fingers, and improved resistance to atmospheric oxidation and salt spray compared to conventional brass shells.
