PTC Resettable Fuses are electrical components that can be installed with circuits to prevent various hazardous conditions. The 16R160BU is a popular two-current-limiting PTC resettable fuse that can provide a reliable solution to many applications. This article will discuss the application field and working principle of the 16R160BU.
The 16R160BU applies to the protection of AC household electrical appliance and low-power DC electrical equipment. It is used to protect the circuit from short circuit, over-current and over-temperature conditions. It is especially suitable for protecting low-power audio and video equipment, such as DVD players, TVs, digital cameras and other consumer electronics. It is also suitable for protecting low power AC adapters of computers, modems and printers.
The working principle of the 16R160BU is simple. When the current flowing through the circuit is less than the rated current, the 16R160BU works like a regular low resistance closed conduction, ignoring the current. When the current reaches or exceeds the rated current, it provides a thermal protection, which is achieved by melting a solder film that is part of the chip, creating a break in the circuit.
When the current reaches the rated current, the PTC will cause a self-heating phenomenon due to Joule heating. As the temperature of the PTC increases, the resistance of the fuse will correspondingly increases and reaches the maximum value, limiting the current, and protecting the circuit from overload. The current is then held at the maximum rated current level.
When the current is lowered below the rated level, the PTC begins to cool and the resistance value decreases. This process is repeated as the current fluctuates, protecting the circuit from over-current. However, if the current exceeds the rated level for a long period of time, the PTC will be damaged and will have to be replaced.
The 16R160BU also provides over-temperature protection through an internal temperature sensing element. When the temperature increases beyond the rated level, the PTC will disconnect the circuit, thus protecting the circuit from overheating and fire hazards. This feature is useful for preventing fire accidents.
The 16R160BU is a popular two-current-limiting PTC resettable fuse that is designed to protect circuits from short-circuits, over-current and over-temperature conditions. It is suitable for low-power audio and video equipment, such as DVD players, TVs, digital cameras and AC adapters of computers, modems and printers. It provides over-current and over-temperature protection that can be reset when the current is lowered below the rated level or when the temperature decreases below the rated level.
