Introduction to WE772
Specification WE772 was originally prepared by the
Royal Aircraft Establishment (RAE) and the Atomic
Weapons Research Establishment (AWRE) to define a
range of filters for use in aircraft equipment and missile
applications.
This specification is also known
as DEF. STAN. 59-45 / 90 / 013.
although never issued as such.
Although nominally obsolete,
filters designed and tested to
meet the requirements of this
specification are included to fulfil market demands.
These filters are particularly designed to suit the
exacting requirements for protection of military and
aerospace equipment, such as explosive devices,
missiles and flight control systems. They will also be
suitable for other rigorous applications and may meet
the requirements of other military and aerospace
specifications.
In line with the original requirements of the
specification, these filters are also available with a
4.7MΩ shunt resistor fitted in parallel to the capacitive
element to prevent static charge and to ensure safe
discharge of the capacitor. See ordering details for
information on how to specify this feature.

Construction
The hermetically sealed screw-in panel mount EMI SL range
filters feature bright tin plated steel bodies and bright tin
plated copper alloy conductors. In all cases the capacitive
element is a low ESR high performance discoidal ceramic
multilayer device.
All parts are hermetically sealed to provide environmental
protection to the internal elements with zero outgassing.
The filters are 100% tested for sealing performance during
manufacture.
Filters with case style SLS and fitted with inductors (L-C,
C-L, Pi or T configurations) are fitted with wound coil or
iron powder core inductors dependant on current flow.
These inductors offer maximum performance with minimal
degradation of insertion loss due to through currents. All other
filters incorporating inductors are fitted with conventional
ferrite beads and are primarily intended for signal lines. They
will carry current to the maximum rated value, but will provide
reduced performance at maximum rated current.
Plating Finish
All the hermetically sealed EMI filters are plated with bright
tin after assembly. The internal surfaces are copper plated to
prevent whisker growth inside the filter assembly.
Alternative plating finishes (eg nickel / silver / gold / SnPb)
are available - please contact the factory to discuss your
requirements.
Voltage Rating
The quoted voltage rating is the maximum dc voltage up
to 125ºC. Voltage spikes can have a significant effect on
the reliability of the filter, and must be taken into account if
anticipated. If in doubt, please contact the factory.
As a general guide, dc rated ceramic filters are suitable for
ac operation subject to a voltage derating ratio of 4:1 - ie
a 400Vdc rated filters is suitable for operation at 100Vac.
However, heating effect and power dissipation (frequency and
capacitance dependant) must also be taken into account -
please contact the factory to discuss any specific application.
Current Rating
All current ratings quoted are maximum continuous operating
currents for temperatures up to 105ºC. Between 105ºC and
125ºC the current rating must be de-rated linearly from 100%
quoted maximum to 60% quoted maximum.
Allowance must be made for any anticipated surge currents.
Filter Circuits
C, L-C, C-L and Pi filter configurations are available
as standard. T filter and multi-element (eg L-C-L-C-L)
configurations are available upon request. Please contact the
factory for more information.

Resistor
Certain filters are also available with a 4.7MΩ shunt resistor
fitted in parallel to the capacitive element to prevent static
charge and to ensure safe discharge of the capacitor. Please
contact the factory to discuss your requirements.
Typical circuit configurations
Dielectric Material
All filters in the hermetically sealed range utilise stable X7R
dielectric to achieve the optimum balance of stability and high
capacitance. Low capacitance ultra stable C0G/NP0 parts are
also available.
Also available are variants incorporating MOV dielectric
materials to provide the dual role of filtering and bi-directional
clamping. This material is available in all variants, but is
especially suited to Pi filter configuration, where it can be
combined with a conventional high capacitance ceramic
disc to provide improved filtering performance. As a general
guideline, Syfer can supply varistor filters to a maximum
clamping voltage of 100V.
Custom Specials
In line with our existing business, Syfer welcomes enquiries
for custom design filters. We are happy to consider
modifications both electrical and mechanical. Please contact
the factory with your specific requirement.
Safety
Care should be taken not to exceed the maximum rated
voltage and current for the filter.
All the filters in this catalogue are designed to operate at
high currents / high voltages and may be fitted with high
capacitances resulting in a potential electric shock hazard.
Electrical energy may be stored for some time after switch
off – do not handle filters without first discharging and / or
checking that the stored voltage is at a low level.
