Product Spotlight Ag9900

Ag9900 Ultra Miniature POE

Spotlight Ag9900

Ag9900M series fully released! The cutting edge in POE ultra-miniaturisation from Silvertel. 40% smaller even than the tiny Ag9800, Ag9900M pushes back the boundaries for POE integration again. At just 21.2 x 13.9mm in footprint area, and only 13.35mm high, Ag9900M is truly the smallest POE module in the world. Despite its' tiny footprint and package size, Ag9900 still packs a maximum 12W of output power through improved efficiencies in design. Better yet, the Ag9900MT version is derated for industrial temperature range working with over temperature protection built in. Perfect for squeezing POE into the smallest of products & packages. Read more about the Ag9900M here. Samples are available now, contact your local distributor for details. Ag9912M, Ag9905M and Ag9903M are all now released with the latest Ag9924M 24V output version following shortly.

Ag9900 webAg9900 Series - Ultra-miniature POE

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.

Ag9900 Evaluation Board

Order Codes: EVALAg9903M; EVALAg9905M; EVALAg9912M; EVALAg9903MT; EVALAg9905MT; EVALAg9912MT


These are a range of evaluation boards for testing and evaluation of Silvertels ultra-miniature IEEE802.3af Ag9900M SMT package POE PD modules. It is designed to work with Power Sourcing Equipment (PSE) that supplies power over either the spare pair or the data pair. It is fully compatible with the Ag6100 (and complementary Ag7100) and Ag6400 PSE modules. It can be ordered as one of six options, dependent on the module/output voltage variant fitted, from either Ag9912M, Ag9905M or Ag9903M or with additional over temperature protection fitted, with the MT suffix. Please click on the order codes above, or use the Buy Samples button provided to order boards. The User Manual can also be downloaded below.
