FAQ LAN Transformer: WHS16105G

What should be checked first when replacing a conventional 16PIN 10/100BASE-T LAN transformer with the low-profile 12PIN WHS16105G?

›

Check the pin topology first; do not treat it as a 16PIN device with pins simply removed. The PHY-side and cable-side transmit and receive differential pairs, together with their center taps, follow the WHS16105G 12PIN schematic. During substitution, verify the schematic nets, pin numbers, center-tap destinations, and PCB pads in that order, then complete prototype interoperability and EMC testing.

How much vertical space does the low-profile WHS16105G actually provide for mechanical design?

›

The maximum component height is 2.50 mm. The body is approximately 12.70 ± 0.50 mm × 7.10 ± 0.50 mm, with a 1.27 mm pin pitch. This suits height-constrained terminals, but the mechanical clearance must also include PCB warpage, solder-paste thickness, placement tolerance, and any enclosure compression. Do not use 2.50 mm directly as the total required equipment clearance.

Can the 350 μH inductance specification of WHS16105G be applied as though it were measured with 8 mA DC bias?

›

No. WHS16105G specifies a minimum open-circuit inductance of 350 μH at 100 kHz and 0.1 V, but 8 mA DC bias is not included in that test condition. Design reviews should cite the no-bias condition. If the application imposes continuous DC bias or power current, obtain the applicable curve or seek confirmation from the technical team.

What Certifications Does VOOHU Hold?

›

VOOHU is certified to ISO 9001:2015 and ISO 14001:2015 standards. Our products comply with RoHS, REACH, and CE requirements, ensuring high quality, environmental compliance, and reliable performance for global markets.
