PTC Resettable Fuses

PTC Resettable Fuses are a type of non-destructive overcurrent protection device used in machinery and electronic devices for protection against overcurrent. The YM120D370N100 is a popular PTC resettable fuse that is widely used in a variety of applications. In this article, we’ll discuss the application field and working principle of the YM120D370N100 PTC Resettable Fuse.The YM120D370N100 PTC Resettable Fuse is an overcurrent resettable circuit protection device, designed to protect sensitive electronic components and appliances from overloads and short circuits. It is commonly used in the automotive, marine, and industrial markets, as well as in consumer electronic products such as set-top boxes, home theater systems, computers, and other household electronics.The YM120D370N100 PTC Resettable Fuse consists of a ceramic body covered with a silver-plated metal shell. Inside the shell is a bi-metallic disc that is connected to two conductive terminals. When the fuse is exposed to a current above its rated current, the disc heats up, which causes the fuse to open and shut off the current path.To reset the fuse, the disc must be cooled down to its normal operating temperature. This is done by removing the power source to the circuit. Once the temperature is lowered, the contacts of the fuse will re-establish and the circuit will be re-energized.The YM120D370N100 PTC Resettable Fuse has several advantages over conventional fuses including its low cost, high reliability, and its ability to reset automatically without the need for intervention or replacement. Additionally, the fuse is able to protect sensitive components that can be damaged by current or voltage spikes due to its self-resetting mechanism. The YM120D370N100 PTC Resettable Fuse has a maximum operating temperature of 125°C, a resistance of 2.7 ohms with a rated current of 100A, and a voltage rating of 330V. It is certified to UL1450, UL1778, and IEC60269-2-2 standards for safety. The advantages of the YM120D370N100 PTC Resettable Fuse make it an ideal choice for a variety of applications. It can be used to protect motors, generators, power supplies, lighting, audio equipment, electrical appliances, and other equipment. It is also effective in protecting circuit boards from overcurrent and is suitable for automotive applications, marine applications, and other industrial applications. In conclusion, the YM120D370N100 PTC Resettable Fuse is a reliable and cost-effective protection device for a wide range of applications. With its ability to reset automatically after being exposed to an overcurrent, it is an ideal choice for protecting sensitive components and electronics from damage.
