PTC Resettable Fuses are ideal for device protection due to their ability for delayed action and automatic resetting. They provide electrical protection by monitoring current levels in an electrical system and cutting off the flow of current once the preset threshold has been exceeded. One such device is the RXE050s (FSL Ambra PTC), which is designed to protect battery operated circuits from excessive and potentially damaging overloads. In this article, we will discuss the application field and working principle of the RXE050s.

The RXE050s is designed for low voltage applications, such as those using a 3.6V lithium polymer battery, as well as automotive and solar panels. It is a cost effective solution for low voltage device protection, with a current rating of 0.5A and voltage rating of 7V. As an overcurrent protection device, the RXE050s utilizes a PTC element to detect and react to excessive current levels. The device is constructed with two metal plates separated by an insulating layer and coated with a PTC element. When the threshold is exceeded, the PTC element will heat up, causing the two metal plates to expand and separate, thereby cutting off the current flow. The two plates will then reset to their original positions once the current level returns below the threshold.

The RXE050s is a low-resistance PTC Resettable Fuse, meaning that it has a much lower resistance during normal operation than when it trips. This low resistance minimizes power consumption of the circuit, but still offers the necessary protection. It also features low internal voltage drops, reducing the output voltage while still providing sufficient safety. The device is also self-regulating, meaning it does not require any external input to operate and can self-reset.

The RXE050s offers a long-term reliability and is suitable for various applications, such as mobile phones, transportation systems, industrial renewable energy systems, and consumer electronics. Furthermore, since it is a low-resistance device, it can support greater current levels than traditional fuses and is capable of withstanding high temperatures.

When it comes to installation and setup, the RXE050s is user-friendly and easy to install. It features a modular design and is able to be used in a variety of configurations. This allows it to be used in parallel with other devices for a customized protection. Additionally, due to its small size, it takes minimal space, making it an ideal for tight spaces.

Overall, the RXE050s is an effective, cost efficient, and reliable overcurrent protection device. It is suitable for a wide range of applications and is easy to install. In addition, since it is a low-resistance device, it is capable of handling higher current levels and is able to withstand extreme temperatures. The device is self-regulating and features a modular design, making it a great choice for device protection.
