FAQ LAN Transformer: WH16603T1
Q
Which dimensions should define the PCB footprint and height limit when WH16603T1 is used on a low-profile board?
A
The body is approximately 12.70 ± 0.50 mm × 7.10 ± 0.50 mm with a maximum height of 2.50 mm. Pin pitch is 1.27 mm, the center-to-center distance between pad rows is 10.80 mm, and the longitudinal pad span is 8.89 mm. The mechanical height allowance must also include solder paste, PCB warpage, and assembly tolerances; 2.50 mm is not the absolute equipment clearance.
Q
WH16603T1 operates up to +105 °C. Why must non-operating storage still remain below +85 °C?
A
The operating-temperature range is -40 to +105 °C, while the storage-temperature range is -40 to +85 °C; they apply to different component states. A high-temperature operating project must verify the actual local component temperature, PHY link, and board lifetime. Shutdown, warehousing, and transportation must not exceed the +85 °C storage limit simply because the operating maximum is higher.
Q
Which time and temperature points are critical in the reflow profile for WH16603T1?
A
The critical limits are a heating rate no greater than 3 °C/s, 60-150 s above 217 °C, a peak temperature of 250 ± 3 °C, 20-40 s within ±5 °C of the actual peak, a cooling rate no greater than 6 °C/s, and no more than 8 min from 25 °C to peak. Measure the reflow profile on the actual board and oven-zone setup before mass production.
Q
What Certifications Does VOOHU Hold?
A

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.
