10K Ohm (10kΩ) 2W 1% Axial Through Hole Resistor - MOF

The 10K Ohm (10kΩ) 2W 1% Axial Through Hole Resistor - MOF is a high-precision, medium-power resistor designed for applications that require accurate resistance values and stable power dissipation. Built with Metal Oxide Film (MOF) technology, this resistor offers low noise, high stability, and excellent durability under varying conditions. The 1% tolerance ensures precise resistance, making this component ideal for high-performance circuits.

Resistance Value (10K Ohms):

The 10,000 ohm (10kΩ) resistance is one of the most commonly used values in electronic circuits, offering a good balance between current limiting and voltage division. It is widely used in circuits where medium resistance is required to control current flow, set bias points, or form part of a voltage divider.

Typical applications include:

• Voltage Divider Networks: In voltage dividers, the 10kΩ resistor helps set precise voltage levels. It is especially useful in sensor circuits, signal conditioning, and ADC (Analog-to-Digital Conversion) systems, where accurate voltage control is needed.
• Signal Processing: In RC (Resistor-Capacitor) and RL (Resistor-Inductor) networks, this resistor plays a crucial role in shaping signal responses and filtering unwanted frequencies. It’s ideal for audio circuits, RF circuits, and other signal-processing applications.
• Biasing Active Components: The 10kΩ resistor is used in biasing circuits for transistors, op-amps, and other active components, ensuring they operate at their optimal point. This makes it a key component in amplifiers, oscillators, and voltage regulators.

Power Rating (2W or 2 Watts):

The 2W power rating means this resistor can safely dissipate up to 2 watts of power. This makes it suitable for medium-power applications, where moderate voltage or current is involved, but excessive heat buildup isn’t a concern.

Common applications for the 2W power rating include:

• Current Limiting: The 10kΩ 2W resistor can be used to limit the amount of current flowing through sensitive components such as LEDs, transistors, or integrated circuits. It is ideal for LED drivers, motor control circuits, and power supply circuits that require current regulation.
• Power Regulation: It is useful in power supply circuits and voltage regulation applications, where the resistor dissipates moderate power without causing overheating. The 2W rating ensures safe operation in these contexts.
• Signal Filtering: The 2W power rating also enables it to work in filter circuits for audio, radio frequency (RF), and other signal processing applications where power dissipation is moderate.

Tolerance (1%):

The 1% tolerance means that the actual resistance will be within ±1% of the nominal value of 10kΩ. This level of precision is critical in circuits where tight resistance values are necessary to ensure the performance and stability of the system.

The 1% tolerance is ideal for:

• Precision Feedback Circuits: In op-amps, voltage regulators, and amplifiers, accurate resistance is needed for stable feedback loops and to maintain the desired gain and response.
• Voltage Regulation: For voltage regulation systems, the 1% tolerance ensures that the resistor remains accurate over time, contributing to stable output voltages.
• Calibration Circuits: In calibration applications, precise resistors like the 10kΩ 2W 1% resistor are required to ensure accurate measurements.

Axial Through-Hole Mounting:

This resistor features an axial through-hole design, with leads extending from both ends. These leads pass through holes in a printed circuit board (PCB) and are soldered to the other side, providing a secure mechanical connection and reliable electrical conductivity.

Benefits of the axial through-hole design include:

• Mechanical Durability: The through-hole mounting ensures that the resistor is securely fixed to the PCB, reducing the risk of damage from mechanical stress.
• Ease of Handling: It is easier to handle, solder, and replace compared to other mounting types, making it ideal for prototyping, repair work, and field maintenance.
• Reliable Electrical Connection: The leads are soldered through the PCB, providing a strong and consistent electrical connection.

The Metal Oxide Film (MOF) construction offers several advantages over traditional carbon-based resistors:

• High Voltage Resistance: MOF resistors can handle higher voltages, making them suitable for high-voltage circuits.
• Better Thermal Stability: These resistors have better resistance to temperature fluctuations, maintaining a consistent resistance even under varying conditions.
• Durability: The MOF construction enhances the resistor’s resistance to thermal overload and mechanical stress, ensuring long-term reliability and performance in demanding applications.

MOF resistors also have a lower temperature coefficient, meaning they experience less change in resistance over temperature variations, contributing to stable circuit performance.

Applications:

• Current Limiting: The 10kΩ 2W resistor is ideal for current-limiting circuits, especially in LED drivers, sensor circuits, power supplies, and motor drivers. It helps protect sensitive components from excessive current and ensures proper functioning.

• Voltage Divider Networks: The 10kΩ resistor is widely used in voltage divider circuits to generate specific voltage levels. It is commonly found in sensor interfaces, ADC systems, and signal conditioning circuits that require controlled voltage outputs.
