PTC Resettable Fuses: B59940C80A70 Application Field and Working Principle
PTCs, also known as polymeric positive temperature coefficient resistors, are temperature-sensitive devices used in a device to protect the circuitry from dangerous overloads and short circuits. These devices are capable of resetting themselves after a current overload, providing protection for your system without the need to change out the fuse. In particular, B59940C80A70 is a new generation of PTC Resettable Fuses designed for a wide range of applications from consumer appliances to industrial machines. It can detect overcurrent condition quickly and accurately, plus it has a wide temperature durability range for reliable performance. This article will cover the application field and working principle of the B59940C80A70 PTC Resettable Fuses.Application Field
In accordance with its features, the B59940C80A70 PTC Resettable Fuses has an extremely wide application range that includes but not limited to charger, lighting, medical care, IGBTs, electric vehicle, and automotive electronics. In particular, this fuse is especially designed for the consumer electronics market such as laptop adapter, mobile phone charger, and mobile power bank. Its wide application range makes it one of the most popular and sought after PTC Resettable Fuses on the market.Working Principle
The B59940C80A70 PTC Resettable Fuses are designed with a high temperature resistant material, usually polyimide or other thermoplastic materials. When there is no current overload, the polymer remains heat stable and will not increase in temperature. However, when a current overload occurs, the temperature of the polymer will quickly increase until the rated current is reached. At this point, the current will be cut off and the fuse will “trip”. The heat generated by the polymer will also reset the connection between the fuse and the circuit, providing a resetting function.When the power is restored, the B59940C80A70 PTC Resettable Fuse will detect that the current has been reduced and will reset itself automatically, allowing the circuit to be reconnected. This makes the B59940C80A70 PTC Resettable Fuse ideal for devices and circuits that require an uninterrupted power supply and protection from overcurrents.Conclusion
As a new generation of PTC Resettable Fuses, the B59940C80A70 utilizes high temperature resistant materials to provide a reliable resetting feature for overcurrent protection in a wide variety of applications. This fuse is particularly suitable for consumer electronics market in laptop adapter, mobile phone charger and mobile power bank. It is more accurate, faster and reliable than traditional fuses and is one of the most sought after PTC Resettable Fuses on the market today.The specific data is subject to PDF, and the above content is for reference
