22K Ohm (22kΩ) 2W 1% Axial Through Hole Resistor - MOF

The 22K Ohm (22kΩ) 2W 1% Axial Through Hole Resistor - MOF is a high-precision, medium-power resistor designed for demanding applications that require accurate resistance values and stable performance over time. Manufactured with Metal Oxide Film (MOF) technology, this resistor provides improved thermal stability, high voltage tolerance, and low noise. Its 1% tolerance ensures the resistor's resistance remains within a very narrow range, making it perfect for precision circuits where exact values are essential.

Resistance Value (22K Ohms):

The 22,000 ohms (22kΩ) resistance value is commonly used in a variety of circuits, especially where moderate resistance is needed to control current flow or create specific voltage levels. It plays a key role in applications that involve voltage division, signal processing, and biasing active components.

Common applications include:

• Voltage Dividers: This resistor is often used in voltage divider circuits to scale voltages and produce precise voltage levels. It is particularly useful for sensor interfacing, analog-to-digital conversion (ADC) circuits, and signal conditioning.
• Signal Processing: The 22kΩ resistor is frequently found in RC (Resistor-Capacitor) and RL (Resistor-Inductor) filter networks, where it helps to filter or shape signals in audio, radio frequency (RF), and other communication systems.
• Biasing Active Components: It is widely used to set the correct biasing for transistors, operational amplifiers, and other active components in amplifiers, oscillators, and voltage regulators.

Power Rating (2W or 2 Watts):

The 2W power rating indicates that the resistor can safely dissipate up to 2 watts of power without being damaged. This makes it suitable for medium-power circuits where moderate heat dissipation is required but high power handling is not necessary.

Applications of the 2W power rating include:

• Current Limiting: The 22kΩ 2W resistor is ideal for current-limiting applications, where it helps regulate the flow of current to prevent damage to sensitive components such as LEDs, transistors, and integrated circuits.

• Signal Conditioning: The 2W power rating makes it suitable for use in signal conditioning circuits, where it is combined with other components (like capacitors or inductors) to filter or process signals in various communication and audio applications.

Tolerance (1%):

With a 1% tolerance, the 22kΩ resistor will have a resistance value within ±1% of its nominal resistance. This level of accuracy is critical in applications where exact resistance values are necessary for the proper operation of the circuit.

Benefits of the 1% tolerance:

• Precision Feedback: The 1% tolerance ensures that the resistor can be used in feedback circuits for amplifiers, voltage regulators, or oscillators, where precise resistance is needed for stable performance.

• Calibration Applications: For calibration circuits, the 1% tolerance ensures that the resistor remains within tight specifications over time, providing accurate and reliable measurements.

Axial Through-Hole Mounting:

This resistor features an axial through-hole design, meaning it has two leads extending from each end. These leads are passed through holes in a printed circuit board (PCB) and soldered on the opposite side, providing a reliable electrical connection and ensuring mechanical stability.

Advantages of the axial through-hole design:

• Strong Mechanical Mounting: The leads pass through the PCB, providing a secure mechanical connection that holds the resistor firmly in place.
