Restore fuse selection 1. Determine the following parameters of the circuit: a Maximum working environment temperature b Standard operating current c Maximum working voltage (Umax) d Maximum fault current (Imax) 2.Select a self-resetting fu....
The operating principle of the resettable fuse is a dynamic balance of energy. The current flowing through the resettable fuse generates a certain amount of heat due to the thermal effect of the current (all resettable fuses have a resistan....
Resettable fuse is an overcurrent electronic protection component. High molecular weight organic polymer is used under high pressure, high temperature, and vulcanization reaction conditions. After doping with conductive particle material, i....
I. Overview KTY series of monocrystalline silicon temperature sensor is the latest international temperature sensor, he can be -55 ℃ to 300 ℃ range of temperature measurement, such as air conditioning, oven and so on. Especially in the....
PTC thermistors for overtemperature protection The need for continuous operation in the production of lathes,Electric oven,Ball mushrooms and other mechanical and electrical equipment and other unattended equipment,Due to motor overheating....
Polymer PTC temperature sensor. A surface mount polymer PTC (positive temperature coefficient) temperature sensor using a conductive polymer polymer composite material as a main material. Different from the traditional ceramic PTC temperatu....
Composite PTC thermistor with double protection function of over-voltage and over-current protection WMZ13A series composite PTC thermistor. YaXun Electronics has creatively packaged a PTC thermistor with overcurrent protection and a varisto....
I believe that people who have contacted electronic components have learned about thermistors, and the thermistors are roughly divided into these three types: Motor start, electronic ballast and energy-saving lamp preheat soft start. Shape....
What is the difference between PTC resettable fuses and overcurrent protection devices such as ordinary fuses, ceramic resettable fuses? The biggest difference between PTC and ordinary fuses is their self-healing characteristics. Both can pr....
When a voltage is applied to the PTCR, a large current I begins to flow. After a certain period of time ts, as the temperature of the PTCR increases, the resistance value increases rapidly, resulting in a sharp drop in current. This period o....
