Through Hole Resistors
Through-hole resistors are circuit components that reduce electrical current flow when its terminal connections are connected in series with a circuit. The resistor reduces the current flow within a circuit board by reducing the voltage. This type of resistor is one of the most common of all types of resistors and is one of the easiest to use. It is also one of the most affordable.
MFR-25FRF52-1R21 is a through-hole resistor and is one of the most popular models of through-hole resistors available. It has a 0.250 watt of power dissipation and its resistance value range is 1 to 21 ohm. The MFR-25FRF52-1R21 is ideal for use in audio, electronic control, lighting, power management, sensing, and metering applications.
This model of through-hole resistor offers a combination of both small size and high inductance. The small size of the resistor reduces the amount of space it will occupy on a printed circuit board. Its high inductance, on the other hand, ensures excellent performance throughout its operational range. The resistor also has a long-life rating of up to 200,000 cycles, which makes it a reliable component for use in industrial applications.
The MFR-25FRF52-1R21 can be used in power-supply, signal conditioning, or metering circuits. Its resistance value can be changed via a variable resistor or potentiometer so it can adjust the current flow of a circuit. In these applications, the resistor reduces the amount of current that passes through the circuit, making it safer and more efficient.
The working principle of the MFR-25FRF52-1R21 is based on a three-lead design. The three leads are two terminals and a central tap. One of the terminals is the negative terminal and the other is the positive terminal. The central tap, or “secondary tap”, is connected to a variable resistor. This variable resistor is used to adjust the resistance of the resistor which in turn controls the amount of current that passes through the resistor.
The MFR-25FRF52-1R21 is an excellent choice for many electronic applications due to its small size, high inductance, and reliable performance. It is also more affordable than other types of through-hole resistors. The resistor is widely used in industrial applications and is typically used in power-supply, signal conditioning, and metering circuits. By adjusting the resistance value through its secondary tap, the current flow of a circuit can be regulated.
