Protection for the electric circuit of Motor. etc.
Automatic Temperature control would be applied in case sudden Temperature change to the higer side is to be happened by utilizing the characteristics of PTC Thermistor which resistance is to be raised at Tc(Cully tenmperature).
The above caracteristics of PTC Thermistor is to be applied for over current protection on the circuit of various products.
Outline
As the 16-V Series for overcurrent protection are low in resistance, they are best for low-voltage circuit protection, automotive motor protection, and current-detecting sensors. After the cause of an abnormality, such as overcurrent, is eliminated, the resistance returns to the original value. This means they can be used repeatedly.
Features
- Being small in size, they provide a high-speed response to overcurrent.
- They continue to protect the circuit from abnormalities until the power is turned off.
- When the power is turned off, the resistance recovers to the original low value; they can be used repeatedly.
- No mechanical contacts means no noise.

PTC Thermistor Implementation Facts
Annual production of 20 million units, cumulative production of 400 million units in total over 25 years.
Maximum Technology's PTC thermistor products produce 20 million units per year. In the 25 years since its development, a total of 400 million units have been shipped.
As for automotive applications, it is used in about 70% of automobiles in Japan, and it is a highly trusted product in the industry.v
Fully domestic production with high-quality PTC thermistors
All production is carried out in domestic factories, and we produce from the materials.
The adjustable material allows for fine customization of the temperature within ±5 degrees.
Of course, it is small and the shape can be customized.
By producing from materials in a domestic factory, we also achieve high quality and reliability.
World-class ultra-low resistance for a wide range of applications
By using the liquid phase method to manufacture the material, we have achieved world-class ultra-low resistance. This makes it possible to reduce the size of PTC thermistors.
By adjusting the material in-house as described above, we could support various customizations and use it for a wide range of applications.
