PTC resettable fuses, often referred to as polymeric positive temperature coefficient or PPTC, are growing in popularity due to their ability to safely interrupt power flow without permanently breaking a circuit. B59301P1080A062 is no exception, being a popular and widely adopted product by manufacturers and customers alike. This article will discuss the application field and working principle of B59301P1080A062 PTC Resettable Fuse.

PTC resettable fuses typically come in two types – multilayer type and monolithic type (the B59301P1080A062 is considered to be a monolithic type fuse). These types of fuses feature a temperature-sensitive ceramic-encapsulated material that, when exposed to a steady current draw far beyond the intended design, will shut off the circuit to protect it. The key difference between the two types of fuses is the way in which they respond to overload current draws. When the multilayer type is overloaded, it quickly trips and opens the circuit, whereas the monolithic type trips slowly, allowing current to slowly build up until the circuit eventually opens.

The B59301P1080A062 PTC Resettable Fuse is designed specifically for low operating current applications. It is capable of withstanding operating currents from 5mA to 350mA and maximum 2.5A breaking capacity. Its tripping time is 90 minutes at nominal conditions and its continuous operating temperature range is from -40°C to 85°C. The device is designed to be used across a wide range of applications, including consumer electronics, data storage, LED lighting, and computing equipment. It has a compact size, measuring in at only 22.2×18.5x1.9 mm, making it easy to incorporate into small-spaced designs, as well as applications with tight packaging constraints.

In terms of working principle, the B59301P1080A062 PTC Resettable Fuse will trip slowly when it senses an over-current situation. This is because the fuse utilizes a special ceramic element which has a higher resistance when exposed to an over-current. This is done by relying on the so-called “self-heating” effect of the ceramic, which causes the ceramic’s temperature to rise and consequently results in an increase in its resistance. The resistance increase then progressively slows the current passing through, thus preventing damage to the device. A thermal crimped connection from the housing to the PCB allows for an easy and reliable connection.

The B59301P1080A062 PTC Resettable Fuse is an ideal device for over-current protection in low-current applications. It boasts a wide temperature range, a large breaking capacity, and a compact size, making it suitable for a wide range of applications. Its special ceramic material also makes it highly effective in tripping slowly when over-currents are sensed, thus allowing for optimal protection of the connected components.
