Compact Device For
Thermal Protection Against
SCHURTER’s RTS (Reflowable Thermal
Switch) is a particularly compact
device for thermal protection against
overheating power semiconductors. The
device is designed to protect against
thermal runaway, reliably interrupting
the circuit precisely at a pre-defined
The RTS can be mounted using
conventional reflow soldering techniques
with temperature profiles up to 260°C.
After the solder process, the RTS is
mechanically activated by depressing
the top into place, arming the RTS to trip
at 210°C. It can be performed manually
or automatically in the case of several
devices being activated at once. In contrast to devices using electrical activation, with
an additional contact, the status of the RTS is clearly and immediately visible to the
installer. The need for an additional contact is also eliminated.

Rugged Relay Designed
For Harsh Inductive
TE Connectivity (TE) has
announced the release of its new
CII FC-335 series relay. Designed
to manage harsh inductive,
motor, and lamp loads, this high-performance relay offers a rugged
means of power switching in a
range of aerospace, defense,
and marine applications. TE’s
new relays are built to handle
higher capacity loads than most
comparable mid-range relays on
the market, offering a 35 A/28 VDC
resistive load rating.
TE’s CII FC-335 series relays
are built in accordance with MIL-
PRF-6106 to ensure they meet
rigorous military standards for
use in power distribution, fuel
pumps, guidance and navigation
systems, weapons systems, and ground support equipment. The relays are designed
with double make contacts that share the load across two contact sets, which helps
minimize wear and tear, prolong relay life, and provide more stable performance.

The RTS sustains operating currents
up to 100 A at rated voltages up to 60
VDC in a 6. 6 mm x 8. 8 mm package.
The main contacts are suitable for
use in 360-800 Hz variable frequency
