Ceramic Positive Temperature Coefficient Thermistor (PTC) - SETsafe

Over Current Protection（51）
- Miniature Fuses（23）
  Miniature Fuses
  Miniature Fuses is an Over Current Protection device. Its resistance is very low. When the circuit works normally, it is equivalent to a wire, which can conduct the circuit continuously and stably. When the current fluctuates due to circuit instability or external interference, it should also be able to withstand a certain range of overload. Only when overload or short circuit happens, Miniature Fuses can blow fast to protect the circuit. SETsafe | SETfuse Miniature Fuses is widely used in all kinds of electrical equipment. It has a variety of mounting modes, compact structure, reliable and stable performance. Technical parameters of SETsafe | SETfuse Miniature Fuses: Its rated current ranges from 0.1 A to 40 A, rated voltage ranges from 125 VAC to 500 VAC, and from 24 VDC to 600 VDC, complies with RoHS and REACH, and is approved by cURus, VDE, PSE, CCC, CQC, KC, TUV.

Overview

PTC thermistors are temperature-dependent resistors based on special semiconductor ceramics with a high positive temperature coefficient (PTC). They exhibit relatively low resistance values at room temperature. When a current flows through a PTC the heat generated raises the temperature of the PTC. Once a certain temperature (Curie temperature) is exceeded, the resistance of a PTC rises significantly.This effect can be used to protect circuits or devices against overcurrents. In this case, the overcurrent brings the PTC to a high temperature and the resulting high resistance then limits the overcurrent. When the cause for malfunction is eliminated the PTC will cool down and act again as a resettable fuse. With this property, PTC thermistors are used as overcurrent protection devices in many fields such as telecommunications, home appliances, and automobiles. SETsafe | SETfuse's CPTC has a high resistance temperature coefficient, and the available Curie temperature ranges from 40°C to 320°C. The resistance of the product is in the range of 0.5Ω to 10KΩ. Diversified structures can be customized.
