Thermal Cut-Offs

SDJ1/SDJ2

GENERAL

Our Thermal Cut-Offs (Organic Thermal Element

Type) are used to prevent ﬁres caused by

abnormal heat generation from circuits and other

heat producing electrical products. They are a

non-resettable thermal fuse which open electrical

contacts when temperatures exceed the speciﬁed

level.

OPERATING PRINCIPLE

APPROVALS

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.

UL & cUL: E117626

VDE: 115369, 116219

PSE: JET2926-32001-1001-1009

CCC: 2003010205079617

EK: HH05009-2004A-2019A

APPLICATIONS

• Electric home appliances and heating devices

• Coil-winding products and power supplies

• Ofﬁce equipment and telecommunication devices

• Automobiles & other electronic components

DIMENSIONS (mm)

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 -24°C.

• 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.

ON APPLYING

TOLERANCE: +0ºC, -5ºC

T = Functioning Temperature T = 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 : 24ºC (Tp-Th) (Apply 35ºC for Ts value when Tp is

higher than 170ºC.)

• 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.
