1. Superior 18mA DC Bias OCL (Anti-Saturation Architecture):

Standard commercial PoE connectors test inductance at 8mA or 11mA DC bias. The LPJK6003AONL guarantees ≥350 μH at 18 mA DC Bias, ensuring that high DC PoE currents combined with ambient temperature spikes do not saturate the internal ferrite cores.

2. Dedicated PoE+ Power Rails (VC1 – VC4):

• VC1 (Pin 13) & VC2 (Pin 14): Routed directly to Line-side Center Taps on data pairs (J4, J5).
• VC3 (Pin 15) & VC4 (Pin 16): Routed directly to Line-side Center Taps on spare/data pairs (J7, J8).
• Full support for continuous 720 mA power delivery in Mode A or Mode B configurations.

3. Integrated Bob Smith Termination:

Includes four 75 Ω resistors, four 22 nF / 100 V decoupling capacitors, and a 1000 pF / 2 kV ceramic spark capacitor terminating directly into the grounded metal shield to dissipate high-voltage common-mode transients.

Internal Magnetics & PoE+ Saturation Resilience

• Shield Construction: Copper Alloy Brass H65Y (0.20 mm Thickness) with integrated multi-point top and side EMI Spring Tabs for solid chassis enclosure bonding.
• Insulator Body: High-temperature Thermoplastic PBT + 30% Glass Filled, flame retardant to UL 94V-0 (Black).
• Gold Contact Interface: Phosphor Bronze C5210R-EH (0.35 mm thickness) plated with Gold 6 micro-inches minimum over nickel underplating.
• Dimensions: 32.50 mm Length × 16.60 mm Width × 13.50 mm Height.
• Enhanced Wave Solder Thermal Rating: Evaluated to withstand wave solder tip temperatures of 265°C Max for up to 5 Seconds, providing higher thermal resistance margin during automated lead-free assembly.

100% Pre-Shipment Quality Testing

1. RoHS Analyzer Screening: X-Ray Fluorescence (XRF) verifies compliance with EU RoHS 2011/65/EU and REACH, guaranteeing lead-free solder pins and housing.
2. EMI Shielding & Tab Contact Test: Dynamic spring deflection and ground plane contact resistance checks ensure continuous −30 dB common-mode isolation.
3. 1500 Vrms Dielectric HiPot Testing: 100% production screened at 60 Hz to ensure total galvanic isolation between power-bearing line pairs and PHY traces.
4. Auto Transformer Analyzer under 18mA Bias: High-precision automated parameter screening verifying that all internal channels maintain ≥350 μH at 18 mA DC bias, with exact 1CT:1CT turns ratios.
