Resin filled screw mounted EMI filters
General
The ceramic capacitor, which is the heart of the filter, can be
damaged by thermal and mechanical shock, as well as by
over-voltage. Care should be taken to minimise the risk of
stress when mounting the filter to a panel and when soldering
wire to the filter terminations.
Mounting to chassis
Mounting torque
It is important to mount the filter to the bulkhead or panel
using the recommended mounting torque, otherwise damage
may be caused to the capacitor due to distortion of the
case. When a threaded hole is to be utilised, the maximum
mounting torque should be 50% of the specified figure which
relates to unthreaded holes. For details of torque figures for
each filter range, please see below.
Tools
Hexagonal devices should be assembled using a suitable
socket. Round bodied filters may be fitted to the panel in one
of two ways (and should not be fitted using pliers or other
similar tools which may damage them):
l
in using a simple purpose-designed tool.
l
inserted into slotted holes and retained with a nut.

Grounding
To ensure the proper operation of the filters, the filter
body should be adequately grounded to the panel to allow
an effective path for the interference. The use of locking
adhesives is not recommended, but if used should be applied
after the filter has been fitted.
Minimum plate thickness
Users should be aware that the majority of these filters have
an undercut between the thread and the mounting flange of
the body, equal to 1.5 x the pitch of the thread. Mounting
into a panel thinner than this undercut length may result
in problems with thread mating and filter position. It is
recommended that a panel thicker than this undercut length
be used wherever possible.
Maximum plate thickness
This is specified for each filter in order that the nut can be
fully engaged even when using a washer.
Soldering to axial wire leads
Soldering temperature
The tip temperature of the iron should not exceed 300°C.
Dwell time
Dwell time should be 3-5 seconds maximum to minimise the
risk of cracking the capacitor due to thermal shock.
Heat sink
Where possible, a heat sink should be used between the
solder joint and the body, especially if longer dwell times are
required.
Bending or cropping of wire leads
Bending or cropping of the filter terminations should not be
carried out within 4mm (0.157”) of the epoxy encapsulation,
the wire should be supported when cropping.
RoHS compliance
All surface mount filters, resin sealed panel mount filters
and power filters are fully RoHS compliant through material
exemption, although care must be taken not to exceed the
maximum soldering temperatures of surface mount parts.
Standard hermetic sealed panel mount filters use SnPb
solders as part of their assembly, and are intended for exempt
applications such as aerospace or military. Substitution of the
SnPb solder with Pb free solders is possible to create a RoHS
compliant part – please contact factory for further details.
Hermetic panel mount EMI filters
General
The ceramic capacitor, which is the heart of the filter, can be
damaged by thermal and mechanical shock, as well as by
over-voltage. Care should be taken to minimise the risk of
stress when mounting the filter to a panel and when soldering
wire to the filter terminations.
Mounting to chassis
Mounting torque
It is important to mount the filter to the bulkhead or panel
using the recommended mounting torque, otherwise damage
may be caused to the capacitor due to distortion of the case.
Tools
All these devices should be mounted into appropriate shaped
mounting holes. Use of the correct mounting hole will lock
the filter body from turning. Pliers or similar tools must not be
used as these will cause damage to the body and risk damage
to the hermetic seal or ceramic discoidal.

All filters are supplied with appropriate nuts and washers.
The nuts should be tightened using a suitable socket set to, or
below, the maximum tightening torque as above.
Thread design and mounting hole details
All the hermetic filters incorporate thread run-outs which may
need to be allowed for in panel design.
Grounding
To ensure the proper operation of the filters, the filter
body should be adequately grounded to the panel to allow
an effective path for the interference. The use of locking
adhesives is not recommended, but if used should be applied
after the filter has been fitted.

Soldering temperature
The tip temperature of the iron should not exceed 300°C.

Dwell time should be 3-5 seconds maximum to minimise the

Heat sink
Where possible, a heat sink should be used between the
solder joint and the body, especially if longer dwell times are
required.
Bending or cropping of wire leads
Bending or cropping of the filter terminations should not be
carried out as this is likely to result in damage to the glass
seal.
