PTC Resettable Fuses are widely used in a variety of applications, ranging from portable electronics to touch-screen modules. 16VT200ULU is one of the most popular resettable fuses as it offers a wide range of features and benefits. In this article, we will discuss 16VT200ULU’s application field, working principle and how it functions.

Application Field of 16VT200ULU Resettable Fuse

16VT200ULU is designed for use in automotive, industrial, telecom and consumer appliances, providing excellent circuit protection in applications with high current inrush effects. It is also widely used in consumer digital products such as mobile phones, digital cameras, audio-visual products and tablets. This resettable fuse is rated to handle current up to 20A, with a maximum voltage range of 16VDC and a maximum operating temperature of 85°C.

It exhibits superior characteristics against varistor-like behavior, making them an ideal solution for protecting a circuit from over-voltage, inrush current, and over-heating scenarios. The fuse provides superior surge handling capability combined with high temperature performance and low self-heating. This product is ideal for use in protecting circuits from over-voltage, inrush current, and over-heating. It is suitable for use in low-current applications, voltage and power conditioning, and as safety back-up protection.

Working Principle of 16VT200ULU Resettable Fuse

The 16VT200ULU resettable fuse works on the principle of thermal expansion. In normal operation, the current flow through the resistor and the thermal element of the fuse. As long as the current is at a normal level, the resistor will not heat up, and the fuse will remain closed. When the current rises above a certain level, the thermal element in the fuse will heat up and the resistor will expand, causing the connection to open, thereby cutting off the power supply to the circuit.

When the current drops back to the normal level, the thermal element will cool down, and the resistor will shrink. This will cause the connection to close, and the power supply will be resumed. This resetting process is relatively fast, as the protection is triggered only when the current exceeds the nominal value. This feature makes the 16VT200ULU an excellent choice for circuits needing short circuit and over-current protection.

How 16VT200ULU Fuse Functions

The 16VT200ULU resin coating helps to provide reliable and efficient circuit protection and ensures a stamped legend for easy identification. It is also designed to be compatible with a variety of industrial and consumer appliances and equipment, such as telephones, networking equipment, automotive and electrical appliances. The fuse has a power rating of 125VAC/DC and a maximum voltage of 60VAC/DC.

The 16VT200ULU operates at a temperature of up to 85°C and can be used in a range of environments. It has a high current withstand rating and is UL and CSA recognized, making it an ideal choice for a wide range of applications. The 16VT200ULU is designed to trip at 30-35A and reset at 20-25A allowing for a wide range of current and voltage protection applications.

In addition, it features a double-fault protection system that prevents damage to the components in case of an overload or short circuit. The fuse is also designed to react quickly to shocks and vibration, providing reliable over-voltage and over-current protection in a variety of rugged conditions. All in all, the 16VT200ULU is a reliable and efficient resettable fuse that provides superior protection and strong resistance to shock and vibration.
