SMD PI Network Test Jigs
TFP-7 Data Sheet


Transat’s Model TFP-7 Pi Network Test Jigs are designed for measuring quartz crystals in SMD packages. The model TFP-7L is identical to the TFP-7 with the exception that it contains a socket which allows insertion of a Load Capacitor in series with the crystal. Different versions of the TFP-7 with varying contact pin spacing exist for various SMD packages. For a particular TFP-7 version (with a given pin spacing) various "Locator Plates" may exist to accommodate different SMD packages with different external dimensions. The second page of this data sheet shows the various TFP-7 versions and their associated Locator Plates.

Load Capacitors

Transat offers both Fixed and Variable Capacitors for use with the TFP-7L PI Networks. A separate data sheet is available for the Variable Capacitors.

Leaded Crystal Packages

Transat also offers PI Networks (Models TFP-6,TFP-6L, TFP-8, & TFP-8L) for crystals in leaded packages. A separate data sheet is available for these models.

IEC 444 - PI Network Specifications

A separate Application note which describes Transat PI Networks and IEC 444 compliance is available upon request.
