Introduction

Polymeric Positive Temperature Coefficient (PTC) Resettable Fuses are a form of overtemperature protection devices. Unlike regular fuses, they automatically reset after being tripped, thus eliminating the need for replacement. They are commonly used in industries where critical loads may be exposed to short circuit or overload conditions. A variety of different reset technologies can be used for various applications.The B59980C0080A070 is a PTC Resettable Fuse that is used to protect against the destructive effects of short circuit and overload conditions. It has a variety of uses in various applications and is designed to provide a high level of protection in order to protect sensitive electronics from damage. This article will provide an overview of the technology, application field and working principle of the B59980C0080A070 PTC Resettable Fuse.

Technology

The B59980C0080A070 is an integrated circuit that is designed to protect sensitive electronics from potential damage caused by short circuit and overload conditions. It is based on a polymeric Positive Temperature Coefficient of Resistance (PTCR) that works by detecting temperature increases and then tripping the fuse at a preset level. This temperature is typically above a safe level for a given system. The B59980C0080A070 contains several distinct parts, including a ceramic substrate which provides the thermal mass and heat distribution for the PTC. Additionally, a quartz-filled polymeric material is used as the primary PTCR element, which is heated and expands when the surrounding temperature rises. This expansion increases the contact between the PTCR material and its surroundings, creating a stronger electrical connection that trips the device.

Application Field and Working Principle

The B59980C0080A070 has a variety of applications, ranging from industrial to consumer products. It is designed to protect sensitive electronics from short circuiting and overload damage. In industrial applications, it is commonly used to protect motors, pumps, lighting systems, power supplies, and other equipment. In consumer products, it is used to protect electronic devices such as mobile phones, tablets and laptops. The working principle of the B59980C0080A070 is based on the polymeric Positive Temperature Coefficient of Resistance (PTCR). When the device is exposed to short circuit or overload conditions, the temperature around the PTCR element increases. This results in the temperature corresponding to the preset level being exceeded, causing the PTCR material to expand and break its contact with its surroundings, thus tripping the fuse. The device then resets after the temperature has returned to a safe level. The B59980C0080A070 is designed to protect against a range of current values. It has an operating temperature range of -55°C to 125°C and can detect current values from 0.2A to 10A, with a tripping time of 0.2ms to 50ms. As a result, it is able to detect a wide variety of short circuit or overload conditions and provides a high level of protection to the device it is connected to.

Conclusion

The B59980C0080A070 is a PTC Resettable Fuse that is used to protect against potential damage caused by short circuiting and overload conditions. It is designed with a polymeric Positive Temperature Coefficient of Resistance (PTCR) which is triggered when the temperature around the PTCR element rises above a preset level. This causes the PTCR material to expand and break contact with its surroundings, thus tripping the fuse and protecting the device or machinery it is connected to. The device is able to detect current values from 0.2A to 10A, with a tripping time of 0.2ms to 50ms, and is suitable for a wide range of applications.
