FAQ LAN Transformer: WHD20805G

Why can WHD20805G and WHD20702G not be interchanged directly even though both are 20PIN devices with 2.00 mm pitch?

›

The decisive differences are row spacing and body depth. WHD20805G has 10.16 mm row spacing and an approximately 12.50 mm body depth, while WHD20702G has 7.62 mm row spacing and an approximately 10.00 mm body depth. Although both have an 18.00 mm longitudinal pin span, their PCB hole coordinates and board area are different, so they cannot share a footprint.

Which signal parameters should be checked on both channels of WHD20805G?

›

Each port should separately meet a minimum open-circuit inductance of 350 μH at 100 kHz, 0.1 V, and 8 mA bias, together with a maximum insertion-loss magnitude of 1.1 dB from 1 to 100 MHz. Crosstalk attenuation and common-mode rejection should each have a magnitude of at least 30 dB from 1 to 100 MHz. Testing only one port does not represent the complete dual-port component.

What should be considered for through-hole production when WHD20805G is supplied at 24 pcs/tube?

›

Each tube contains 24 parts. Calculate line-side quantities, partial-tube balances, and changeover remnants by tube count. Before loading, use an actual part to confirm tube orientation, the pin 1 marking, the recommended 0.90 mm hole diameter, and insertion-fixture positioning. For automatic insertion, also verify that the 21.20 mm × 12.50 mm body does not interfere with the fixture or adjacent components.

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.
