Minimum
inductance
is
measured
with
the
core
halfway
out
of
the
coil
form.
Carbonyl
E
&
J
material
cores
are
available
1/4",
5/16",
or
3/8"
long.
Aluminum
cores
are
available
1/4"
or
5/16"
long.
The
electrical
specifications
for
series
936
were
made
with
6-32,
.250"
long,
carbonyl
"J"
core
through
7
1/2
turns,
and
a
.375
long
carbonyl
"J"
core
8
1/2
turns
and
9
1/2
turns.
Other
core
lengths
and
materials
are
available.
Inductance
less
than
0.1µH
are
calculated
from
readings
taken
at
40
MHz.
Inductances
greater
than
or
equal
to
0.1µH
are
taken
at
the
recommended
"Q"
meter
frequency.
All
inductances
include
Standex
test
fixture
number
429G.
Fixture
inductance
is
approximately
.040µH.
Series
936
is
"spacewound".
Electrical
winding
"tap"
is
available
on
the
936
series.
The
coil
may
be
molded
in
various
positions.
The
coil
may
be
installed
in
the
shield
can
in
alternate
positions.
Coil
form
material
for
the
series
is
polypropylene.
These
coils
may
be
tuned
with
Standex
tuning
wrench
996.
Series
936
is
28
TPI.
The
O.D.
of
the
windings
is
.208".
Distance
from
the
mounting
surface
to
the
first
turn
is
.07".
Standex
specifications
are
subject
to
change
without
notice.
