Thermal Cut-Offs                                        APPROVALS
SDJ1/SDJ2                                            UL & cUL: E117626
                                                     VDE: 115369, 116219
   GENERAL                                           PSE: JET2926-32001-1001-1009
Our Thermal Cut-Offs (Organic Thermal Element        CCC: 2003010205079617
Type) are used to prevent fires caused by            EK: HH05009-2004A-2019A
abnormal heat generation from circuits and other
heat producing electrical products. They are a          DIMENSIONS (mm)
non-resettable thermal fuse which open electrical
contacts when temperatures exceed the specified
level.

    OPERATING PRINCIPLE
When the ambient temperature rises to the function-
ing temperature, the thermal element melts and the
springs move the contact away and open the circuit
permanently.

   APPLICATIONS
Electric home appliances and heating devices
Coil-winding products and power supplies
Office equipment and telecommunication devices
Automobiles & other electronic components

   CAUTIONS
Bends in leads should be at least 3mm from the

body of the TCO.
Extreme caution must be used while soldering,

use a heatsink and avoid heating above Tf -24C.
The metal portion of the TCO is electrically live

and may require insulation.
Do not use in liquids or poisonous gasses such as

sulfuric acid or nitrous oxide.
Do not connect heater directly to the cutoff.

TF = Functioning Temperature TH = Holding Temperature
   DETERMINE THE PROPER SERIES

Tp : The highest temperature of the product to which a
       cutoff is to be attached.

Th : The safe temperature range for use of the cutoff.

Ts : 24C (Tp-Th) (Apply 35C for Ts value when Tp is
       higher than 170C.)

To : The heating temperature caused by electrical load
       (Please refer temperature / current correlation curve)

+a :
1. Self heating of lead wire
2. Structure of ventilation or airtightness
3. Location of connecting terminal
4. Thickness of insulated covering material
5. Best condition value considering electric voltage changes

Tp + Ts + To +a = Applicable Temperature

   SAFE TEMPERATURE RANGE
The increasing temperature by remaining heat in the cutoff after melting is required to remain below Tm.
The temperature of the area where a cutoff will be attached should not reach over Th under normal usage conditions.
