TECHNOLOGY NICHE
Polymeric PTC material and devices technology synergistically integrate the advance polymer material
technologies, conductive material science, novel processing engineering, and fundamental electronic
and electrical theory. Electrical resistance of such material and devices increases with temperature
increases and vice versa. When experiencing “overcurrent and/or over voltage”, the device generates
thermal energy (Energy = I*V) and heats up itself. This makes polymer matrix’s morphology change
from crystalline to amorphous phase, and results in a resistance increase of thousand orders of
magnitude such that “trip” the electricity. The device will remain hot and stay “tripped” until the fault is
cleared and power is removed.
OVERVIEW GB CELL
NOTE : All Specification subject to change without notice. 2
HOW DOES THE RESETTABLE FUSE WORK
FUZETECÔ resettable fuses are designed and made of patented novel polymeric PTC material in thin
chip form, developed solely by FUZETEC. With electrodes and leads attached on both sides, it is
placed in series to protect a circuit. At “normal operating condition” the device remains at an extremely
low resistance (mini-ohms) and allows the electrical current to flow through it without any restriction.
When overcurrent conditions occur, the polymeric PTC material heats up and its resistance increases
sharply. Such a sharp resistance increase (to an insulated status) cuts off the current in the circuit, and
consequently protects the element and device in the circuit. Upon fault current being removed, the
resettable fuse cools and its resistance drops to the original extremely low value. The resettable fuse is
“resetted” and allows the current through the circuit again.
TRIP CURRENT, HOLD CURRENT AND THERMAL DERATING
Trip Current (IT) and Hold Current (IH) of FUZETECÔ resettable fuse are rated at 23

. Typically its
Trip Current is twice as much as its Hold Current. FUZETEC Ô device does not trip at or below its
rated Hold Current, and will trip at or above its Trip Current value. However, due to PTC effect both IT
and IH reduce with ambient temperature increase and vice versa. As shown bellow, the currents are
reduced nearly 50% at 85

and increased to 150% at -40

.

Warning: - Each product should be carefully evaluated and tested for their suitability of application.
-Operation beyond the specified maximum rating or improper use may result in damage and possible electrical
arcing and/or flame.
-PPTC device are intended for occasional overcurrent protection. Application for repeated overcurrent condition
and/or prolonged trip are not anticipated.- Avoid contact of PPTC device with chemical solvent, including
some inert material such as silicone based oil, lubricant and etc. Prolonged contact will damage the device
performance.
- Additional protection mechanism are strongly recommended to be used in conjunction with the PPTC device
for protection against abnormal or failure conditions.- Avoid use of PPTC device in a constrained space such
as potting material, housing and containers where have limited space to accommodate device thermal

Solder reflow

Due to “Lead Free” nature, Temperature and
Dwelling time for the soldering zone is higher
than those for Regular. This may cause
damage to other components.
1. Recommended reflow methods; IR , vapor phase
oven, hot air oven.
2. The FSMD1812 Series are suitable for use with
wave-solder application methods.
3. Recommended maximum paste thickness is
0.25mm.
4. Devices can be cleaned using standard industry
methods and solvents.
CAUTION:
If reflow temperatures exceed the recommended
Profile, devices may not meet the performance
requirements.
Rework:
Use standard industry practices.

Solder reflow

Due to “Lead Free” nature, Temperature and
Dwelling time for the soldering zone is higher
than those for Regular. This may cause
damage to other components.
1. Recommended reflow methods; IR , vapor phase
oven, hot air oven.
2. The FSMD1206 Series are suitable for use with
wave-solder application methods.
3. Recommended maximum paste thickness is
0.25mm.
4. Devices can be cleaned using standard industry
methods and solvents.
CAUTION:
If reflow temperatures exceed the recommended
Profile, devices may not meet the performance
requirements.
Rework:
Use standard industry practices.

Fuzetec PPTC Resettable Fuses Technology
PPTC Applications by Industry
www.fuzetec.com mail©fuzetec.com.tw
The conductive carbon black particles in Fuzetec’s PPTC resettable fuses are dispersed in a polymer that has
a crystalline structure. At normal operating conditions there are numerous carbon chains forming conductive paths
trough the material. Under fault conditions (Tripped State), excessive current flows through the PPTC device and
the PTC material heats up making the conductive particles move apart from each other, most of them no longer
conduct current and the resistance of the device increases sharply. Upon fault current being removed, the
resettable fuse is resetted and allows the current through the circuit again.
When connected in series to a circuit,
Fuzetec’s PPTC resettable fuses remain
at extremely low resistance and allow
the electrical current to flow through it
without any restriction. When overcurrent
situations occur, Fuzetec PPTC resettable
fuses limit the current to a very small value
and therefore protect the circuit from being
damaged by the high current.
