Encapsulated Thermostats for Electronics
F20-E06
Formerly Called F11-E06
ADVANTAGES
The miniature size, high
switching
capability
and
versatility of its contacts make
the JEDEC TO-220 compatible
device ideal for printed circuit
board mounting. The F20-E06
is epoxy sealed to withstand
wave soldering and board
washing operations.
APPLICATIONS
The F20-E06 is ideal to
sense the temperature of
a surface or of stagnant air
in an enclosure and can
be supplied for mounting
on a printed circuit board
or with flexible wire leads
for remote installation. Its
high temperature resistance
and high dielectric strength
make it the favored device
for protecting heatsinks. Heat
sensitive semiconductors and
other valuable equipment
can be saved from thermal
damage by shutting down the
power or simply turning on a
fan.

DESCRIPTION
The CANTHERM F20-E06 has been
designed to protect today’s technology
and meet the requirements of
tomorrow’s innovations. The F20
snap action bimetallic element will
respond rapidly and accurately to
changes in the temperature of the
surface to which it is mounted or the
air temperature in an enclosure. The
single pole, single throw contacts
can be configured as either normally
open or normally closed, operating
on rise in temperature. The average
automatic reset will occur at a
temperature approximately 20 - 25C
below the calibrated set point.
The housing has been designed for
demanding conditions such as high
continuous temperatures and high
voltage electrical isolation. The PC
version is supplied with TO-220 style
stamped lead-frame leads and are
shipped in a 50 piece plastic magazine
for ease of insertion and handling.
OPERATING
TEMPERATURES
The F20-E06 is available from
65ºC to 160ºC with either
normally closed or normally
open contacts. Increments
are 5ºC and standard
tolerance is ±5ºC.
CONNECTIONS
The F20-E06 is available
for PC board mount or a
variety of flexible wire leads.
Standard leads are 6”, 24
AWG UL Black up to 3398
150ºC and UL1180 Teflon up
to the maximum temperature.
ADD “-PC” to the part number
for solid pins or specify flexible
lead type. Other wire types,
gauges and lead lengths
available upon request.

CURRENT SENSIVITY
F20-E06
The thermostats are not current sensitive at rated
currents. At loads above the rated values, up to
maximum loading there is self-heating of the current
carrying contacts.
* When N/0 contacts are closed, self heating will
occur at currents exceeding normal rating. It is
possible that, given certain combinations of set
temperature current & ambient temperature, the
contacts will not reset.
** Wire insulation must be appropriate
