Ag9900 is now the smallest PoE module in the world, superseding the Ag9800. It is designed such that adding just two diode bridges and an electrolytic capacitor to this truly tiny module is enough to enable PoE functionality in a product. Ag9900 is fully compliant to the IEEE 802.3af PoE standard. It provides a POE signature, classification, isolation and DC to DC conversion options for 12V, 5V or 3.3V, while taking up minimal PCB space. It is ideal for space constrained PoE applications such as IP phones, wall mount appliances, IP cameras, thermostats, smoke detectors and room sensors, and is perfect for a whole range of new IoT sensors and devices.

  • Low cost & simple integration 
  • Integral DC/DC converter 
  • 1500V isolation 
  • Power: 12W/12V, 9W/5V or 6W/3.3V
  • Industrial temperature option 
  • Overload & short-circuit protection
  • Fully IEEE802.3af compliant POE
  • 40% smaller than any other PoE solution
  • Smallest in the world
  • SMT-21mm(L)x 14mm(W)x13.35mm(H) 
  •  Miniaturised POE PD module

The Ag9900 series PD modules pushes the boundaries of POE miniaturisation further than ever before, yet still offers all the features expected from Silvertel’s POE. This is the smallest package size available that is designed to extract power from a Cat5 cable, fully conforming to the 802.3af Power-over-Ethernet (PoE) standard and includes 1.5kV isolation, PoE signature and an integral DC to DC converter. The module provides a Class 0 signature.

Silvertel’s Ag9900 is ideally suited as a cost effective solution for POE for any application, but particularly for very small devices and space limited designs such as IP phones, WAPs, sensors and access control panels.
