The WHSQ24706-2PTG carries 1200 mA of DC balance current in each magnetic channel, and its datasheet rates the device at 60 W for PoE.That figure applies to each channel on its own: it is not a total across the port's two channels and must not be multiplied by the coil count to produce a port current.
The datasheet names no IEEE 802.3 clause, so VOOHU states the current and wattage capability of the WHSQ24706-2PTG rather than compliance with a standard. The power finally available at the powered device also depends on the PSE, the cabling and the thermal design of the finished equipment. Other options are listed in the2.5G/5G BASE-T range.
The insertion loss, return loss, crosstalk and common-mode rejection of the WHSQ24706-2PTG are all specified only up to 200 MHz.Other parts sharing the same footprint carry those same four items to 250 MHz, so check the frequency ceiling before comparing figures between them, or limits taken from different bands end up side by side.
Above 200 MHz the WHSQ24706-2PTG has no published limit. Where a qualification plan has to cover a higher band, ask VOOHU for measured data on this part rather than inferring it from a part specified to a higher ceiling.
Yes. The 150 μH minimum of the WHSQ24706-2PTG is quoted at 100 kHz and 0.1 V with a 14 mA DC bias applied.That bias is a direct current superimposed during the inductance measurement, so that the figure reflects the core with a DC component present. It is not the same quantity as the 1200 mA of DC balance current the WHSQ24706-2PTG carries in each channel, the two cannot be converted into one another, and the bias is not a permitted operating current.
TheWHSQ24702-1PTGshares the footprint and also quotes a 150 μH minimum, but publishes no bias condition, so the two minima do not sit on the same measurement basis and should not be compared directly.
