General
High Voltage Reed Relays
The principal function of a high voltage reed relay is to isolate as high
Relays manufactured by Crydom have one of the following contact a voltage as possible. In order to achieve this all Crydom high voltage
reed relays employ evacuated reed switches. These switches are
arrangements:

directly equivalent.
Soldering & Cleaning
CrydomÕs reed relays are high performance products and the
materials and methods of construction are significant factors
in achieving performance specifications. The following guidelines
should therefore be followed when adopting assembly, soldering and
cleaning processes:
1) Soldering. Crydom propose that either low residue fluxes are
used in the soldering process (to eliminate the need for cleaning),
or that the reed relays are fitted onto the PCB after the cleaning
process has taken place. If a solder bath is employed the
maximum immersion time recommended is 10 seconds at 250¡C
or 3 seconds at 350¡C.
Contact Material - Rhodium vs Tungsten
Rhodium contacts should be used where very low contact resistance
is required or when power switching at <1000V is undertaken.
Tungsten contacts perform best when switching high voltages
(1-10kV) at very low current. It should be noted that switching
power will reduce relay operating life - the factory should be
contacted for advice on specific applications.
Magnetic Screening
Crydom high voltage reed relays are generally supplied with
magnetic screening fitted. However, this is not absolute and so, if the
minimising of interference is critical, the mounting configuration in
figure 1 below is recommended.
FRD12000/13000 Series: Electrical connection to the contacts of
the FRD12000/13000 Series relay is via the reedswitch leadout.
Care must be taken when hand soldering, as physical and
thermal shocks can damage the glass to metal seals. A thermal
shunt (aluminium clamp) carefully applied to the reedswitch
leadout, adjacent to the glass seal will reduce the chances of
breakage due to thermal shocks.
Alternatively, the relays should be warmed prior to soldering.
2) Cleaning. It is impossible for Crydom to offer blanket approval of
methods, due to the many and varied automatic cleaning systems
now available to conform to recent legislation.
If, after the soldering process, the customer wishes to clean PCBÕs
containing Crydom reed relays then the use of post operative
cleaners such as IPA or HCFC based solvents with low pressure
brush applicators is recommended. Any customer wishing to use Figure 1 : Recommended Mounting for ‘S’ and ‘D’ Series High Voltage Reed Relays
an alternative cleaning system should ensure that the fluids and
processes are appropriate for application on Crydom reed relays.
CrydomÕs devices are not hermetically sealed and as such,
exposure to certain fluids can result in the degradation of the
relay materials and subsequently a reduction in the electrical
performance. Please contact Crydom for further information on
the suitability of various cleaning solutions.
RF Reed Relays
The basic requirements of RF reed relays are to provide minimal RF
signal loss and very low contact resistance over a long operating
lifetime. This is achieved in Crydom RF reed relays through the use of
copper plated reed switches with Rhodium contacts in conjunction
with carefully designed coil assemblies. They are intended for use
across the frequency range 1-30MHz and typical RF parameters for
an RF reed relay across this band (measured in a 50 Ohm system) are
shown in figure 2 below:
As an illustration of the effect of relay screening on ESR,
measurements taken under load at 30MHz (i.e. the worst case
frequency) are shown in figure 3 below for fully, partially and
unscreened ÒFRDÓ series reed relays.

electromagnetic coupling between reed switch and coil results in some
energy being dissipated in the coil. This dissipation manifests itself as
an addition to the effective series resistance (ESR) of the relay and, at
currents of several amps, heating of the relay coil. RF coil heating is
greatest at high frequencies and varies in proportion to the square of
the RF current carried in the switch. It is this factor which limits
maximum carry current at high frequencies and ambient temperatures.
The purpose of RF screening is to reduce these losses and extend
relay performance at high frequencies and high ambient temperatures.
Crydom RF reed relays are available with no screening, partial
screening and full RF screening of the coil, depending upon the
requirements of the application.
Relays without an RF screen have restricted current carrying
capability at high ambient temperatures and frequencies (and a
higher associated ESR). However, this suits many typical ATU
applications well, as the highest currents occur only at the lower
frequency bands (e.g. 2MHz).
Relays with partial RF screening have extended current carrying
performance at elevated ambient temperatures over unscreened
variants.

6 Series
Miniature, Fully Screened, Open Frame. 3.5kV, 4A
Developed closely with RF design Engineers in the radio communications industry,
this new fully screened reed relay series, offers low RF loss and high current
carrying capability. The robust shell construction enables the customer to specify
contact pin configuration. The relay coil section is totally enclosed in a copper
screen, resulting in lower self-heating and RF loss. Together with Crydom's vacuum
reed switches, benefits include higher carry currents for a given frequency and
ambient temperature. Peak RF isolation voltages up to 3.5kV are achieved by
clever coil design maximising pin spacing. Switch connections are offered for
either PCB or Flying Lead mounting
