PTC Resettable Fuses are used in a wide range of applications, including industries such as automotive, consumer electronics, industrial, medical, and white goods. The MF-R400-2-99 is a UL certified, miniaturized surface-mount Polymeric Positive Temperature Coefficient (PPTC) Resettable Fuses designed for use in many different kinds of products and applications. This PTC Resettable Fuse, manufactured by Pulsafeeder, is RoHS-compliant and meets all necessary safety standards.

A PTC Resettable Fuse works by using a resistive heater element. This heater element is safely housed in a metal tube. The metal tube contains a material with high resistivity so that when the current passes through it, the heater element begins to heat up. As the heater element heats up, the temperature of the fuse increases. As the temperature gets to the specified temperature of the fuse, known as the “trip point,” the Polymer Positive Temperature Coefficient (PPTC) material surrounding the heater element begins to swell and the fuse opens. This eliminates the current passing through the fuse and stops further heating of the resistive element.

The MF-R400-2-99 features a variety of features and benefits that make it suitable for a wide range of applications. Its low profile and size make it easy to install in many kinds of products. It has a low resistance of 0.035 ohm, which provides good current carrying capacity and over current protection. Additionally, it has a wide operating temperature range (-20° C to +85° C). This provides additional versatility for various types of applications.

The MF-R400-2-99 is ideal for use in situations where reliable and fast over-current protection is needed. Its self-resetting capability allows it to be used multiple times without requiring the user to replace the fuse. This makes the MF-R400-2-99 particularly useful for a variety of consumer electronics, automotive, industrial, and medical applications. It is designed for use in products that require over-current protection, such as LED lighting, power supplies, motor controllers, and circuit boards.

The MF-R400-2-99 is a reliable and versatile product for many different kinds of applications. Its wide range of features and benefits make it an ideal choice for use in various consumer and industrial applications. It can provide reliable over-current protection and is self-resetting for repeatable use. Thanks to its low profile design, it is also easy to install in many kinds of products and applications.
