WHSQ48802C1 2.5G/5GBASE-T 4PPoE LAN Transformer

1200 mA is the DC balance current of each magnetic channel of the WHSQ48802C1, and a port total is counted across the channels of that one Ethernet port only, never across all four channels of the device. The WHSQ48802C1 is a dual-port part whose two ports are independent, each with its own centre-tap paths, so the per-channel figure cannot be multiplied by eight to describe what the device delivers.

Where a datasheet in this range prints both levels – the WHSQ48002P1 prints 360 mA per channel and 720 mA for full channels – the full-channels figure is the total for one Ethernet port. The WHSQ48802C1 datasheet stops at channel level, so ask VOOHU for the port figure where a thermal budget needs it. Other dual-port options are listed in the 2.5G/5G BASE-T range.

The WHSQ48802C1 operates from -40 °C to +85 °C, and that range already includes the device's own temperature rise. Each magnetic channel carries 1200 mA of DC balance current at a stated PoE Support 60W, which together suit it to 2.5G/5G ports in industrial switches, outdoor enclosures and wide-temperature PoE equipment.

Note that +85 °C is the device temperature ceiling after self-heating rather than a permitted ambient limit, so the ambient inside the enclosure has to leave headroom for that rise. The WHSQ48802C1 also stands 11.70 mm tall, more than other 48-pin parts in this range, so recheck the enclosure clearance.

One thing separates them: how far the high-frequency limits are specified. The WHSQ48802C1 specifies insertion loss, return loss, crosstalk and common-mode rejection to 250 MHz, where the WHSQ48802C2 specifies the same four only to 200 MHz. Everything else is identical on the WHSQ48802C1 and the WHSQ48802C2: package outline, pad layout, pin names and their order, OCL and its 15 mA bias condition, DCR, the isolation test, the operating range with temperature rise included, and PoE Support 60W with 1200 mA per magnetic channel.

Choose the WHSQ48802C1 where the review has to cite limits above 200 MHz; where 200 MHz is enough, decide on availability and on what is already in the bill of materials.
