Filter Installation Guidelines
Threaded Style Filters
Note: For 5/8-24 and 7/16-28 please refer to the specic instruction noted on part drawings or see page 11 of the
Resin Sealed Bolt-in Filters data sheet.
• Exceeding recommended mounting torque may result in
damage to the capacitor within the lter due to possible
twisting or elongation of the case.
• For products without hex surfaces do not hold the lter
with pliers or other gripping tools. Pressure exerted on
the lter case may crack the ceramic capacitor element.
• Proper use of lters requires that the lter case be
adequately grounded to form an eective path for the
interference.
Solder-in Style Filters
• A controlled temperature prole not exceeding 6°F (3°C)
per second is recommended when soldering lters.
• When soldering to terminals of a lter, a heat sink should
always be used adjacent to the body of the lter.
• 60-40 solder is recommended for installation of the lter
into the chassis as well as soldering to the terminals. If
a lter style without an eyelet is being soldered into a
chassis, iron processes should be avoided and the
recommended solder alloy is 60-38-2.
• Installation hole size for a solder-in lter should be 0.003-
0.005” over the maximum tolerance of the minor diam-
eter of the mounting portion of the eyelet with a ±0.002”
tolerance.
• Machine/oven soldering 385-415°F (195-210°C) using
a dwell and cycle time fast enough to reow the solder
and ramped to maintain less than
6°F/sec rate of change.
• For iron soldering to lter body, preheat components at
250-300°F (120-150°C), solder iron is recommended to
be set at 500-550°F (260-290°C). The dwell on the solder
joint should be less than 5 seconds. The time is depen-
dent on the heat sinking provided by the chassis so a
longer preheat may be required.
Soldering to Filter Terminals
• Use a temperature controlled soldering iron with
tip temperature of 525 ± 10°F (275 ± 5°C).
• Use an SN 63 RMA ux core solder.
• Make mechanical wire connection.
• Use heat sink next to lter body where possible.
• Clean soldering iron tip.
• Clip end of solder (remove 0.5”) to expose ux
for soldering.
• Apply soldering iron to wire/ag junction at wetted
solder tip region of iron (Wetted Bridge Method).
Immediately apply solder. Dwell time for soldering
iron tip on product should be 3-5 seconds maximum.
