> e Suitable for high power applications and in many cases, may be used as an alternative to mercury wetted reed relays 

The Series 100 HC Form A versions offer higher coil resistances than the similar specification Series 114, the greater winding space allowing for the use of switches rated to 3 Amps continuous carry current and even higher levels in pulsed current applications. 

Featuring sputtered ruthenium contacts, this also makes them suitable for low level or ‘dry’ switching applications and the reduced heating effect from the higher coil resistances gives them thermal EMF performance less than 10 μV. 

The range features an internal mu-metal screen to minimize problems that would otherwise be experienced due to magnetic interaction when they are closely stacked. Form A versions may be stacked side-by-side. Due to the fact that the Form B types feature an internal biasing magnet, a gap of 0.4 inches minimum should be left between adjacent relays.

For example, for an ‘end of life’ contact resistance specification of 1 Ω, switching low loads (10 V at 10 mA resistive) or when ‘cold’ switching, typical life is approx 10 x 10[9] ops. At 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 condition. 

## Note[2] : Carry Current 

The maximum continuous carry current of 3 Amps can be increased where current pulses are used, the level being dependant on the pulse duration and the duty cycle. For advice, please contact Pickering. 

**Operating Voltages** Coil voltage - nominal Must operate voltage - maximum at 25°C Must release voltage - minimum at 25°C 5 V 3.75 V 0.5 V 12 V 9 V 1.2 V 24 V 18 V 2.4 V ~~———__—~~ 

## **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.

When an internal diode is required, the suffix D is added to the part number as shown in the table. 

## Note[3] : Capacitance across open switch 

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

## Note[4] : Capacitance values 

The value will depend upon on the mode of connection/guarding of unused terminals. Please contact technical sales for details. 

## Note[5] : 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.
