Through Hole Resistors are used to control electrical current flow and are a common component found in both industrial and consumer electronics applications. The MFR25SFBE52-221K is a through hole mounted resistor with a wide range of applications from high power automotive electronics to medical equipment.

In terms of physical size, the MFR25SFBE52-221K is quite small by design. Its size enables it to be used on the high-density circuit boards typical of modern devices. It is available in a standard size of 0.25w x 0.10d inches and is mounted to the board using a standard 2-pin plated-through-hole design.

As for operating characteristics, the MFR25SFBE52-221K has a nominal DC resistance of 221 kHz as well as a tolerance value of ±5%. The resistance range for this device is between 200 kHz and 250 kHz, making it suitable for applications that require a precise resistance value. It also has a rated power dissipation of 0.25 Watts. The low power dissipation ensures that the device operates reliably at elevated temperatures without exceeding the temperature ratings.

One of the most important features of the MFR25SFBE52-221K is its temperature coefficient. This is a measure of the rate at which the device\'s resistance changes with increases in temperature. The MFR25SFBE52-221K has a negative temperature coefficient which means that its resistance decreases - which is desirable for decreasing power supply ripple. At room temperature, the device has a temperature coefficient of -25ppm/°C.

The MFR25SFBE52-221K is primarily used for stabilizing power supply lines in high power applications including automotive electronic systems. It can also be used in medical equipment, telecom equipment, and other high power electronics. The small size and high power dissipation make it well suited for these applications. Additionally, the device is RoHS compliant, making it an attractive choice for environmentally conscious engineers.

To summarize, the MFR25SFBE52-221K is a through hole mounted resistor with a wide range of applications. Its small size makes it suitable for high density circuit boards, while its low power dissipation enables it to operate reliably at high temperatures. Additionally, its negative temperature coefficient makes it well suited for controlling power supply ripple. All of these attributes make the MFR25SFBE52-221K an ideal choice for stabilizing high power electronics in automotive, medical, and telecom applications.
