PTC resettable fuses have multiple advantages over traditional single-use fuses in terms of product longevity and cost. The 1812L110ZR is a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse, designed for overcurrent protection and designed as a replaceable unit making it easier to physically replace existing fuses without having to replace the whole assembly. This article will cover the application field and working principle of the 1812L110ZR.

Application Field

The 1812L110ZR is designed to provide short circuit and overload protection for a variety of consumer, industrial, automotive, and other electronic applications. This fuse is suitable for use in a wide range of wire to board, board to board and industrial products, mainly when space is limited. The 1812L110ZR is capable of controlling various currents depending on makes, from 0.15 to 22A, with voltage ratings of 150VAC (50/60 Hz) and 300VDC. It has an operating temperature range of -55℃ to 85℃.

Some specific applications include low power circuits, smoke detectors, security systems, medical and industrial electronics, power supplies, computers, office equipment, telecommunications, battery chargers, consumer appliances and automotive electronics.

Working Principle

The main component of the 1812L110ZR is a PTC thermistor. When the current exceeds the specified current rating, it generates heat and the electrical resistance increases rapidly, which closes the fuse circuit and interrupts the current. When the overcurrent disappears, the fuse will reset itself and the circuit will become normal.

The superior design of the 1812L110ZR PTC resettable fuse has a self healing feature, which allows the user to reset it manually or by using an electronic circuit or a time delay circuit. This feature also maximizes the number of times a fuse can reset itself, providing it with greater reliability and product life.

The 1812L110ZR PTC resettable fuse incorporates a special design that minimizes the external effects of electromagnetic and radio frequency interference (EMI/RFI). This design also allows it to perform better with higher speed and efficiency as compared to traditional single-use fuses.

Overall, due to its fuse resetting feature, space saving design, resilience to EMI/RFI, and its flexibility for a variety of purposes, the 1812L110ZR PTC resettable fuse is an ideal solution for short circuit and overload protection.
