FMF50SFTE52-1K

Through Hole Resistors

The FMF50SFTE52-1K (OHMITE) is a through-hole resistor that operates at medium-to-low temperatures and is able to handle high voltage applications. It is a widely used through-hole resistor known for its power/heat handling capabilities, with a total power of up to 50 watts. The resistor is designed for use in renewable energy, automotive, communication, and other applications. The resistor body is made from a heat and flame-resistant material, in line with safety regulations.

The most common application for this type of resistor is to reduce power output in amplifier circuits, as the resistor will dissipate the excess power as heat. It is also used in safety equipment and alarms, as they are designed to activate in the event of an overvoltage or overheating in electronic systems. Furthermore, the resistor is used in low voltage supplies and LED lights, as it can operate at up to 54V and is ideal for current limiting.

The resistor is constructed around an AC or DC current limiting element. The current limiting element is either a simple wirewound resistor or a film resistor. In some cases, the current-limiting element is composed of both a wirewound resistor and a film resistor. This composition allows for greater heat dissipation, due to the larger surface area available for cooling.

The FMF50SFTE52-1K is an ideal choice for applications that require continuous temperature stability and high reliability. It is designed to have a lifetime of up to 1 billion cycles, and is capable of safely operating temperatures up to 250ºC. Additionally, the resistor body is encased in a flame-retardant material, ensuring safety even in the most hazardous environments.

In conclusion, the FMF50SFTE52-1K through-hole resistor is a reliable and robust solution for a variety of applications. Its ability to dissipate heat in an efficient manner, combined with its current and voltage limiting capabilities, make it an ideal choice for a wide range of applications. With a lifetime of up to 1 billion cycles, the FMF50SFTE52-1K is a reliable and long-lasting solution for almost any application.
