‘i Additional build options are available Many benefits compared to industry standard relays [Le (see last page) 

The Series 102 is a range of subminiature coaxial reed relays for high frequency applications up to 3 GHz, performance characteristics will be found on reverse of this sheet. Three package types are available, all displaying outstanding RF performance in terms of low insertion loss, good isolation and excellent VSWR characteristics in 50 ohms systems. These relays have good coil drive levels making them ideal for portable applications or where space is at a premium. If an even smaller RF relay is required, look at the Series 109RF or 111 RF. 

## 102M (Mu-metal) Package. 

This device, constructed in the popular Single-In-Line format, features a mu-metal case allowing dense packaging without magnetic interaction problems. It has six pins for conventional PCB mounting. With careful printed circuit board layout this configuration will perform well up to 1.5 GHz, it is easy to use and will meet most requirements. 

## 102F (Flatpack) package. 

The 102F package dispenses with the leadframe connections to the switch and screen. These terminations are instead brought out axially from the ends of the device where they are soldered directly to the stripline. This technique allows very accurate matching to the 50 ohms line and gives an excellent VSWR right up to 3 GHz. 

## 102F Mounting method: 

A small rectangular hole is punched into the printed circuit board or notched into the board edge to accommodate the package. The switch leads are then soldered directly to the 50 ohms stripline, the tin plated copper foil from the screen is soldered directly to the ground plane on the reverse side of the PCB. The coil connections are soldered directly to their tracks in the same way.

## Also available - Low capacitance reed relays 

If your high frequency application does not require coaxial relays, Pickering also manufacture devices featuring very low levels of capacitance between the switch and coil, see our Series 103. These are especially useful for such applications as the switching of ranges and attenuators in computer controlled instrumentation. Contact our sales office for further details.

For example, for an ‘end of life’ contact resistance specification of 1 Ω, switching low loads or when ‘cold’ switching, typical life is expected to be greater than 1 x 10[9] ops. At higher voltages and the maximum load (resistive), typical life is 1 x 10[7] ops. In the event of abusive conditions, e.g. high currents due to capacitive inrushes, this figure reduces considerably. Pickering will be pleased to perform life testing with any particular load conditions.

## **Environmental Specification/Mechanical Characteristics** 

In the table below, the upper temperature limit can be extended to +125 °C if the coil drive voltage is increased to accommodate the resistance/temperature coefficient of the copper coil winding. This is approximately 0.4% per °C. This means that at 125 °C the coil drive voltage will need to be increased by approximately 40 x 0.4 =16% to maintain the required magnetic drive level. Please contact  sales@pickeringrelay.com  for assistance.

## Note[2] : Capacitance across open switch 

The capacitance across the open switch was measured with other connections guarded. 

## Note[3] : Capacitance values 

The value will depend upon on the mode of connection/guarding of unused terminals. Please contact technical sales for details. Note[4] : Insulation resistance 

Insulation resistance will reduce at higher temperatures. For more information on temperature effects click here, or contact Pickering for more in depth guidance. 

The technical information shown in this data sheet could contain inaccuracies or typographical errors. This information may be periodically changed or updated and these changes will be included in future versions of this data sheet.

## **Similar Relays Comparison** 

If the Series 102 is unsuitable for your application, Pickering also manufactures three other reed relay types with similar characteristics, but in different package sizes. 

If your high frequency application does not require coaxial relays, Pickering also manufacture devices featuring very low levels of capacitance between the switch and coil, see our Series 103. These are especially useful for such applications as the switching of ranges and attenuators in computer controlled instrumentation. Contact our sales office for further details.
