　　Low zero power resistance: The self resetting fuse has low impedance, low power loss during normal operation, and low surface temperature.

　　Fast overcurrent protection speed: Due to its material characteristics, the self resetting fuse has a much faster response speed to overcurrent conditions than other overcurrent protection devices.

　　Self locking operation: The self resetting fuse is in an overcurrent protection state, locked in a high resistance state with minimal current. Only after cutting off the power supply or the overcurrent disappears, can the low resistance state be restored.

　　Automatic reset: The self resetting fuse resets itself after providing overcurrent protection (troubleshooting), without the need for replacement.

　　High current resistance: Self restoring fuses have excellent high current resistance, and some specifications can withstand 100A current impact.

　　Application: PPTC has a wide range of applications and can be used in various electronic products, communication products, power supplies, etc.

Principle of Resettable Current Fuses

　　　　Resettable current fuses offer a unique solution for protecting electrical circuits while providing the convenience of being reusable. Here's how they work.　　Resettable current fuses typically use a polymer-based material that changes its electrical resistance in response to an increase in current. When the current exceeds a certain threshold, the polymer material heats up and changes its state, increasing its resistance and limiting the current flow.　　Once the overcurrent condition is removed, the polymer material cools down and returns to its original low resistance state, allowing the circuit to resume normal operation. This resettable feature makes these fuses highly convenient as they do not need to be replaced like traditional fuses after each overcurrent event.　　The principle of operation of resettable current fuses is based on a combination of thermal and electrical properties of the polymer material. The material is designed to have a specific temperature coefficient of re

Wiring method of fuse holder

　　　　The wiring methods of fuse holders mainly include plug-in wiring and threaded wiring. Plug and play wiring refers to inserting wires into the socket inside the fuse holder and clamping them with spring plates to achieve wiring; Screw type wiring is the process of threading wires into threaded holes in the fuse holder and connecting them through the frictional force of the threads. Below, we will introduce these two wiring methods separately.　　Plug and drop wiring is a common fuse holder wiring method. It has the advantages of simple wiring and convenient installation, and is suitable for application scenarios with smaller wire sizes. The spring plate of plug-in wiring needs to ensure sufficient force and reliability when clamping the wire. According to statistics, fuse holders with plug-in connections have a slightly higher electrical failure rate than fuse holders with threaded connections, but their prices are cheaper. The plug-in fuse holder is suitable for low voltage and low c

pptc resettable fuse datasheet.There are several general classifications of thermistors

　　　　A. Classified by temperature variation characteristics - positive temperature coefficient (PTC), negative positive temperature coefficient thermistors.　　B. Classified by sensitivity to temperature changes - high sensitivity type (mutation type), low sensitivity type (slow change type) thermistors.　　C. Classified by heating method - direct heating thermistors, side heating thermistors.　　D. Classified by structure and shape - various types of thermistors such as circular (sheet), cylindrical (cylindrical), circular (gasket), etc.　　The most common names for thermistors are PTC thermistors and NTC thermistors. So what is the difference between these two types of thermistors?　　1、 PTC thermistor　　PTC thermistor structure - made from materials such as barium titanate (BaTiO3), strontium (Sr), zirconium (Zr), etc.　　PTC thermistor characteristics - the resistance value is directly proportional to the temperature change, that is, the resistance value increases as the temperature increases.

Setting of fuse position.motorcycle blown fuse symptoms

　　　　To fully utilize the protective effect of a fuse in a circuit, the position of the fuse in the circuit should be considered when designing the circuit.　　The fuse can be blown in a timely manner to protect the circuit and switch;　　And the fuse cannot be blown in a timely manner, unable to protect the front-end circuit and switch. If a short circuit occurs at B, the fuse can only be blown in a timely manner, which can protect the circuit;　　As shown in the circuit diagram, when a short circuit occurs at point A, the switch will still burn out, while the fuse will not blow, meaning that the fuse in this circuit cannot protect the circuit and electrical components. So the circuit diagram is the most reasonable one for designing the position of the fuse in the circuit.　　Note: For the case where relays and fuses are integrated in the same electrical box, the fuse connection is not closely related (as the possibility of a short circuit occurring within the same electrical box is not high),
