Types of Fuses

Fuses are safety devices that protect electrical and electronic circuits from damage due to excessive current. These devices come in many shapes and sizes and can be broadly categorized based on their working and application fields. Among these categories are save-all fuses, tone fuses, thermal-fuse devices, and 39906300000 fuses.

39906300000 Fuses

29906300000 fuses, also known as Polymeric Positive Temperature Coefficient (PPTC) fuses or Resettable Fuses, are an important and integral component of protection schemes used in consumer electronics. They are used to protect electronic circuits from any abnormal overcurrent condition as they can react very quickly to changing currents thus providing high levels of protection.

Working Principle

The working principle of 39906300000 fuses is quite simple. They are made of materials that exhibit a positive temperature coefficient when exposed to heat. The PPTC fuse is a complex blend of polymers that expand when it experiences a high current. This creates a barrier between the positive and negative terminals which breaks the current circuit and thus preventing further damage.

The PPTC fuse also has the ability to self-reset once the current drops below the level that is specified by the manufacturer. This property makes PPTC fuses an ideal choice for over-current protection in many consumer products such as mobile phones, tablets and electronic control systems.

Applications

PPTC fuses are widely used in consumer electronics for protection against abnormal currents. They are also used in automotive electronics for short circuit protection, motor control, emergency shutdown and many other applications. Besides traditional over-current protection, PPTC fuses are also used for protection in other areas such as surge protection, low voltage disconnect, polarity protection, and power management.

The self-resetting feature makes PPTC fuses an excellent choice in many applications where it is not possible or practical to replace the fuse after an over-current incident. This makes them suitable for applications such as smoke alarms, battery management, and various industrial and automotive applications.

Due to their simple design and reliable performance, 39906300000 fuses are highly reliable and cost effective, and can offer dependable protection in a wide range of applications.
