Teridian Semiconductor Corporation Approves Datatronics Modem Transformer For Reference Designs

Teridian now includes the Datatronic Model PT9281 Modem Transformer on its Model 73M2901CE EVM Demo Board. The new PT79281 is a drop-in device developed to support Teridian IC reference designs that typically include voice applications as well as high speed data modems, satellite set-top boxes, POS terminals, MFP and FAX terminals and IP phones.

The Datatronic PT79281 Modem Transformer is a highly reliable V.22bis modem transformer for use with Teridian IC circuit designs. It provides space-efficient isolation between sensitive electronics and voice or data lines. Featuring a high dielectric strength tested to 3750 Vrms, it helps safeguard equipment users and their data by protecting them from electrical shock.

The Datatronic PT79281 Modem Transformer’s advanced design and construction offers excellent performance. Key specifications include: a primary impedance of 600 ohms, turns ratio of 1:1 ±2 percent, 4.6H shunt inductance and 3.7 mH leakage inductance

The PT79281 V.22bis Modem Transformer comes in a 16.6 mm (0.649 inch) square package with a 10.5 mm (0.417 inch) seated height above the circuit board. Lead terminal finish is RoHS compliant; solder meets J-STD-020D.Its superior performance in a relatively small package makes it ideal for high density circuit designs.

The Datatronic PT79281 Transformer withstands high temperature soldering and operating temperature environments from –40ºC to +105ºC; storage temperature range is -40ºC to +125ºC. The PT79281 comes in tape-and-reel packaging for auto insertion equipment.

In 10,000 piece quantity, the Datatronic PT79281 Transformer is available beginning at $0.37 each. Lead-time is stock to six weeks. Volume OEM pricing is available upon request.
