PTC Resettable Fuses provide an effective and economical solution to the problems of protecting over-loaded and short-circuited circuits. The 0402L020SLKR PTC Resettable Fuse is a great example of this technology, with its highly efficient performance and compact size.The 0402L020SLKR PTC Resettable Fuse offers both over-current protection and over-temperature protection. The PTC fuse utilizes a PTC (positive temperature coefficient) material which activates the fuse due to temperature rise when excess current passes through the wire or component. When this occurs, the material changes from a low resistance best to a high resistance state and stops the flow of current. Once the current is stopped, the heat generated dissipates and the PTC material reverts back to its initial low resistance best, allowing the current to flow once again. This process is repeated over and over until the cause of the excess current is corrected.The 0402L020SLKR PTC Resettable Fuse is ideal for low voltage (24V max) and low current (32A max) applications. Its small size makes it suitable for applications where space is at a premium. The fuse also has a high DC voltage hold-off rating of 500V, making it suitable for use in more demanding applications. It is also RoHS compliant and UL certified. The 0402L020SLKR PTC Resettable Fuse can typically be found in a variety of consumer applications, such as laptop computers, LED lighting, solar power systems, and consumer electronics. It can also be used in automotive applications such as power steering, heating, and air conditioning systems and motor control systems. It is especially suited for automotive applications due to its temperature rating of −40 to +125°C. It can also be used in industrial applications such as machine control systems and vending machines.The 0402L020SLKR PTC Resettable Fuse is also an ideal standalone protection device, as it offers both over-current and over-temperature protection. It is an optimal solution for applications which require effective over-current and over-temperature prevention without needing to use separate over-current and over-temperature protection components.With its highly efficient performance and compact size, the 0402L020SLKR PTC Resettable Fuse is a great choice for both consumer and industrial applications. Due to its temperature rating, it’s especially suitable for automotive applications where effective over-current and over-temperature protection is fundamental for adequate system protection. Its RoHS compliance and UL certification are also valuable assurance of quality and safety, providing keyed piece of mind for both OEMs and end users alike.
