FAQ LAN Transformer: WHD16503G

What mechanical and electrical differences are most easily overlooked when replacing WHD16506G with WHD16503G?

›

The most easily overlooked differences are the longitudinal hole locations and pin definitions. WHD16503G has a 17.78 mm longitudinal pin span, whereas WHD16506G uses 15.24 mm. The center taps and differential pairs are also assigned to different pin numbers. The devices therefore cannot be interchanged simply because both are single-port 16PIN packages with 2.54 mm pitch.

How should the return-loss specification of WHD16503G be interpreted without misreading the sign?

›

Interpret it by attenuation magnitude: at least 18 dB from 1 to 30 MHz, 14.4 dB at 40 MHz, 13.1 dB at 50 MHz, and 12 dB from 60 to 80 MHz. Acceptance records must retain both the frequency point or band and its limit; a single statement such as '18 dB return loss' must not be used for the entire band.

What direct purchasing and production implications follow from the 25 pcs/tube packaging and 0 to +70 °C operating range of WHD16503G?

›

Purchasing should calculate full-tube quantities, opened-tube balances, and changeover remnants in multiples of 25. Before production, confirm pin 1 orientation, the 17.78 mm hole span, and the insertion fixture. The model may operate only from 0 to +70 °C; its -40 to +85 °C storage range does not establish energized operation below 0 °C.

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.
