PTC Resettable Fuses are an important part of the modern power infrastructure. Designed to protect electronic hardware from the harm caused by over-currents, short circuits, and other electrical events that could occur in an electric circuit, PTC Resettable Fuses provide a high level of protection while offering reliable, cost-effective solutions for a wide range of applications. The MF-R016/600-2 PTC Resettable Fuse is one such device. In this article, we will discuss the application field and working principle of the MF-R016/600-2 PTC Resettable Fuse.

Essentially, the MF-R016/600-2 PTC Resettable Fuse operates by responding to the specific requirements of a circuit rather than a generic design or predetermined current limit. A PTC fuse contains a polymeric positive temperature coefficient (PPTC) material that acts as a thermal release element. As the temperature of the element increases, its resistance increases and it eventually transitions into a high impedance state, breaking the electrical circuit. When the current is reduced, the thermal release element will slowly cool and regain its low conductivity state, automatically resetting the circuit without the need for manual reset.

The MF-R016/600-2 PTC Resettable Fuse is well suited for a variety of applications, such as in consumer and industrial electronic equipment, automotive electronics, and HVAC systems. In these situations, the MF-R016/600-2 PTC Resettable Fuse is used to protect low voltage circuit boards from damage due to over-current and short circuit events. Additionally, the fuse is often used in solar and wind power systems, where it protects photovoltaic inverters, charge controllers, and other circuits from potentially damaging over-current events.

The MF-R016/600-2 PTC Resettable Fuse has a nominal operating temperature of -45°C to 105°C, and is rated at 16V/600mA. In addition to its high temperature rating, the MF-R016/600-2 PTC Resettable Fuse also features a high hold current of 1500mA, a fast trip time of 0.9s at 800mA, and a slow trip time of 3 hours at 10mA. It also features a compact size of 5.08mm x 16.3mm, making it ideal for use in space-constrained applications.

The MF-R016/600-2 PTC Resettable Fuse’s working principle is based upon two unique characteristics - its increasing resistance when exposed to an excessive amount of current, and the resulting breaking of the current path. This occurs as the PTC element transitions from a low to high impedance state as it absorbs heat from the current. The element remains in this high impedance state until the current level is reduced, at which point the element cools and regains its low impedance state, thus resetting the circuit.

In conclusion, the MF-R016/600-2 PTC Resettable Fuse is an effective and reliable solution for a variety of applications, such as consumer and industrial electronic equipment, automotive electronics, and HVAC systems. It provides an efficient solution for protecting delicate circuits from the harms of over-current and short circuit events, and features a high rating and compact size, making it ideal for use in space-constrained applications. The fuse’s working principle is based upon its characteristic increasing resistance when exposed to excessive current and the resulting circuit breaking action while cooling.
