0.2 ms0.2 ms0.2 msNote1: Switching Voltage
This high voltage rating is for RESISTIVE loads only. At these high voltages, even stray capacitance can generate very high current
pulses, which can damage the contact plating causing welding of the reed switch. If there is capacitance in circuit, provision should bemade to limit the surge, to within the current and power ratings of the relay.

Note2: Life Expectancy
The life of a reed relay depends upon the switch load and the end of life criteria. For example, for an ‘end of life’ contact resistancespecification of 1 Ω, switching low loads or when ‘cold’ switching, typical life is expected to be greater than 1 x 108 ops. At higher voltages
and the maximum load (resistive), typical life is 1 x 107 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 toaccommodate the resistance/temperature coefficient of the copper coil winding. This is approximately 0.4% per °C. Thismeans that at 125 °C the coil drive voltage will need to be increased by approximately 40 x 0.4 =16% to maintain therequired magnetic drive level. Please contact sales@pickeringrelay.com for assistance.

Contact Resistance
A characteristic of the switch used in this range is the contact resistance can increase over time if subjected to standoff
voltages in the upper range of the specification. This does not affect the life expectancy but can result in contact resistances
greater than 1 Ohm. In most high voltage applications this increase has no effect on performance but, in some mixed signal
applications low and stable contact resistance is important.

Important: Where the optional internal diode is fitted or for all Form B types, the correct coil polarity must be observed, as
shown by the + symbol on the schematics.
Note: A 1 cm space should be left between Form B types and other relays, as the magnetic field from the internal biasing
magnet could slightly affect the sensitivity of the relay alongside.

Specification

High Voltage Surface Mount Reed Relays – Series 219

Moisture Sensitivity of Surface Mount Reed Relays
Quality and reliability concerns regarding internal damage, cracks and delamination from the solder reflow process havedemanded standardised procedures regarding moisture control for some surface mount devices. Pickering Series 219
Surface Mount Reed Relays are classified to IPC/JEDEC J-STD-020 MSL1, and thus dry packs and special procedures are
not required.

Packing
Pickering 219 Series relays can be provided in tape and reel format on request.

Shelf and Floor Life
Through their moisture sensitivity level 1 classification 219 Series relays have an “infinite floor life” when the conditions
are 30 °C/85% RH.

10 Key Benefits of Pickering Reed Relays
Pickering Reed Relays

Typical Industry Reed Relays

1
Instrumentation Grade
Reed Switches

Instrumentation Grade Reed Switcheswith vacuum sputtered Ruthenium
plating to ensure stable, long life up to
5x10E9 operations.

Often low grade Reed Switches withelectroplated Rhodium plating resulting
in higher, less stable contact resistance.

22
Formerless CoilConstruction

Formerless coil construction increases
the coil winding volume, maximizing
magnetic efficiency, allowing the use ofless sensitive reed switches resulting in
optimal switching action and extended
lifetime at operational extremes.

Use of bobbins decreases the coilwinding volume, resulting in having
less magnetic drive and a need to use
more sensitive reed switches which
are inherently less stable with greatly
reduced restoring forces.

3
Magnetic Screening

Mu-metal magnetic screening (either
external or internal), enables ultra-high
PCB side-by-side packing densities withminimal magnetic interaction, saving
significant cost and space. Pickering
Mu-Metal magnetic screen - interaction
approx. 5%

Lower cost reed relays have minimal
or no magnetic screening, resulting inmagnetic interaction issues causingchanges in operating and releasevoltages, timing and contact resistance,
causing switches to not operate at theirnominal voltages. Typical industry
screen - interaction approx. 30%

4SoftCenter™ technology, provides
maximum cushioned protection of thereed switch, minimising internal lifetimestresses and extending the working lifeand contact stability.

Transfer moulded reed relays (produced
using high temperature/pressure),
result in significant stresses to the glass
reed switch which can cause the switch
blades to deflect or misalign leading tochanges in the operating characteristics,
contact resistance stability and operating
lifetime.

100% testing for all operating
parameters including dynamic contact
wave-shape analysis with full data
scrutiny to maintain consistency.

Simple dc testing or just batch testing
which may result in non-operational
devices being supplied.

Limited ability to customize.

Pickering are committed to productlongevity; our reed relays are
manufactured and supported formore than 25 years from introduction,
typically much longer.

Most other manufacturers discontinueparts when they reach a low sales
threshold; costing purchasing and R&D
a great deal of unnecessary time andmoney to redesign and maintain supply.

coil or resistance figures, special life
