FAQ LAN Transformer: WHD20702G

WHD20702G and WHD20805G are both 20PIN, 2.00 mm-pitch devices. What is their most important PCB incompatibility?

›

The most important difference is row spacing: 7.62 mm for WHD20702G and 10.16 mm for WHD20805G. Their body depths are also approximately 10.00 mm and 12.50 mm, respectively. Therefore, even with the same pin count, longitudinal pitch, and 18.00 mm pin span, their through-hole coordinates are incompatible.

Which complete dimensions should be used when creating the footprint and reviewing the mechanical fit of WHD20702G?

›

Use an approximately 21.20 ± 0.50 mm × 10.00 ± 0.50 mm body with a maximum height of 7.20 mm, 2.00 mm pin pitch, 7.62 mm row spacing, 18.00 mm longitudinal pin span, and 0.90 mm recommended hole diameter. The mechanical review should also check clearance to the RJ45 connector, enclosure ribs, and solder-side fixtures.

How should WHD20702G be sampled to avoid missing differences between its two ports?

›

Include both ports in the sampling plan rather than testing an arbitrary single port on each component. At minimum, cover the 1CT:1CT turns ratio, 350 μH minimum open-circuit inductance at 8 mA bias, 1.1 dB maximum insertion-loss magnitude from 1 to 100 MHz, and the 1500 VAC, 1 mA, 60 s dielectric withstand test between windings. The quality plan determines the actual sampling ratio.

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.
