Frequently Asked Questions
What are the PoE electrical ratings and isolation specifications of this Tab-Up RJ45 MagJack?
This 1x1 Tab-Up RJ45 MagJack is compliant with IEEE 802.3af for both PSE and PD applications, supporting a maximum balanced DC line current of 350mA and 57V DC continuous voltage. Every unit is 100% production tested to withstand 2250V DC Hi-Pot isolation between primary and secondary windings for 6 seconds at 1mA maximum leakage.
What are the PCB footprint, keep-out zone, and panel cutout dimensions for this connector?
The connector has an overall body dimension of 16.50mm (W) x 32.50mm (D) x 13.70mm (H) and requires a front metal panel opening of 17.06mm x 13.88mm (±0.10mm). The PCB footprint features 16x Ø0.89mm signal/PoE holes, 4x Ø1.14mm LED holes, 2x Ø1.57mm shield ground holes (16.13mm pitch), and 2x Ø3.20mm mounting holes (12.70mm pitch), along with a 10.75mm x 21.75mm component-side keep-out area.
What wave soldering profile is recommended for assembling this PBT-housed RJ45 jack?
The recommended wave soldering profile specifies a preheating stage between 120°C and 180°C for 60 to 120 seconds, followed by a peak solder tip temperature of 260°C ±5°C for a maximum of 5 seconds (compatible with Sn96.5/Ag3/Cu0.5 lead-free solder melting at 217°C). Slight melting of the bottom PBT positioning columns beneath the PCB after wave soldering is normal and does not affect mechanical or electrical function.
What are the specifications of the integrated Yellow and Green LED indicators?
The connector integrates a Left Yellow LED (Pins 19/20, 585nm wavelength, 1.7–2.2V forward voltage at 20mA) and a Right Green LED (Pins 17/18, 568nm wavelength, 1.85–2.45V forward voltage at 20mA) for independent link and PoE status monitoring.
