02Applications

Where WHSM24015N0 is used

Switches and routers
Wireless access points
IP cameras
Industrial control devices

Typical application

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

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
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.
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: WHSM24015N0

WHSM2415N0 Support to what level PoE

Specifications for PoE Support 30W, each magnetic channel supports 360 ma DC balance current, total 720 maA. 720 MA is the combined capacity of two channels at the port, not 360 MA times four, nor is it a rating for any of the centre's nodes. This is the lowest of the current PoE capabilities of the Beneficials, and if the port is to be supplied at 60 W or higher, the higher current capacity model should be selected. Four paths are designed for copper in a balanced manner for each article 360 MA, and copper width is calculated by the actual copper thickness and permitted temperature rise.

WHSM 24015N0 0 °C TO +70 °C IS THE AMBIENT TEMPERATURE OR THE UNIT TEMPERATURE

is the temperature of the device and this cap already contains its own temperature increase. The specifications indicate a temperature increase in the working temperature line, so +70 & Deg; C is the permitted temperature boundary for the WHSM 24015N0, which is not the allowed ambient temperature limit in the case and cannot be superimposed on it. Thermal design is calculated in reverse: the temperature increase is estimated from +70 & dig; C by the whole windway and the PoE load, and the available environmental temperature surplus is left. This step needs to be measured on the prototype, and the specifications do not provide a temperature curve.

WHSM 24015N0 AND WHSM 24015T0

Viewer working temperature: Require -40 & Deg; C to +85 & Deg; C for WHSM2415T0, 0 & Deg; C to +70 & Deg; C for WHSM2415N0. The PoE calibres in both sections are identical & mdash; — both are PPE Support 30W, a total of 720 MA for each channel, and the rest of the electrical blocks, both of which have temperature caps that contain the temperature of the device. The replacement does not change the electrical design and copper budget, but only the available ambient temperature surplus.
