02Applications

Where WHSM24706C2 is used

  • Switches and routers
  • Wireless access points
  • IP cameras
  • Industrial control devices

Typical application

Ethernet PHYWHSM24706C2RJ45 jackTD+1 TX+TD−2 TX−RD+3 RX+RD−6 RX−ESD / TVS (optional)TX · 1CT:1CTRX · 1CT:1CTCTCTPHY-side CT: bias per PHY typeR1 75 ΩR2 75 ΩC1 1000 pF / 2 kVBob Smith terminationShield to chassis

The transformer isolates the PHY from the cable and couples the TX and RX differential pairs to the RJ45 jack.

Center-tap biasing on the PHY side depends on the PHY type (voltage-mode or current-mode).

Typical application for reference. Follow the PHY vendor's reference design.

Design notes

  1. 01Connect the center taps according to your PHY type.Voltage-mode and current-mode PHYs need different center-tap biasing; a mismatch can break auto-negotiation.Check with your PHY →
  2. 02Terminate the line-side center taps with a Bob Smith network.It gives common-mode noise a defined path to chassis ground and helps EMC.
  3. 03Add line-side surge protection for outdoor or long-cable ports.Residual surge energy through the transformer can still damage the PHY.Troubleshooting guide →

07FAQ

FAQ LAN Transformer: WHSM24706C2

How much PoE current can the WHSM24706C2 handle?

The WHSM24706C2 supports PoE up to 90 W: each channel is rated for 1000 mA DC balance current, and all channels together for 2000 mA. This makes it the high-power option among the 10G BASE-T, 24-pin parts in this outline.

What operating temperature range does the WHSM24706C2 cover?

-40 °C to +85 °C, including the part's own temperature rise. Storage temperature is also -40 °C to +85 °C.

Is the OCL of the WHSM24706C2 directly comparable with the WHSM24702P1?

Not directly, because the two are measured under different bias conditions. The WHSM24706C2 is specified at 100 µH min at 100 kHz, 100 mV with 18 mA DC bias, while the WHSM24702P1 is 120 µH min at 100 kHz, 0.1 V with 14 mA DC bias. When qualifying an alternative, compare inductance under the same test condition.
