MFR50SFRE52-309R

The MFR50SFRE52-309R, known as a through-hole resistor, is a resistor with two electrical leads that are passed through PCBs or other electronics material and riveted into place. This type of resistor is ideal for use in high-power electronic circuits.

The MFR50SFRE52-309R is a high-power resistor used for a variety of applications such as power supplies, circuit breakers, relays, and other high-power applications. As a meta-resistive device, it also displays significant noise reduction and temperature stability. Additionally, the MFR50SFRE52-309R has better shock and vibration resistance than its surface-mount resistor counterparts.

The MFR50SFRE52-309R is constructed from a glass-oxide film, typically wrapped around a ceramic core. It is designed to be able to provide high current ratings and high operating temperatures thanks to its advanced construction and materials. Additionally, the MFR50SFRE52-309R has a low resistance tolerance of ±5%, enabling applications that require very precise control of current and voltage.

The main purpose of the MFR50SFRE52-309R is to reduce or eliminate dangerous and unpredictable high-voltage currents and electrical surges caused by electronic components, or everyday objects like lightning strikes. Operating with a maximum voltage rating of 500 volts, the resistor can quickly shut down power when an overload occurs, protecting sensitive components inside electronic devices.

The MFR50SFRE52-309R offers excellent noise immunity by reducing or controlling any unwanted electrical interference. This ensures that circuits remain stable and that signals are accurately transmitted. Due to their robust construction and reliable performance, these resistors are often used in situations where low signal interference is required, such as in digital communication systems.

The working principle of the MFR50SFRE52-309R is based on the resistance to electrical current. The level of resistance increases as the current passes through the device. As the applied voltage increases, the resistance increases as well, limiting the amount of current that can pass through and a relatively constant voltage (DC voltage) is maintained. The amount of resistance can be adjusted by changing the device’s resistance value, which is typically stamped on the back of the device.

The MFR50SFRE52-309R is a precision resistor, offering excellent temperature stability, excellent noise immunity and a wide range of power ratings, making it a versatile and reliable choice for high-power applications. The resistor’s robust construction, reliable performance and precision make it well suited for use in high-voltage circuits, power supplies and other high power applications.
