150K Ohm (150K) 1W 1% Axial Through Hole Resistor - MOF

The 150K Ohm (150K) 1W 1% Axial Through Hole Resistor - MOF is a high-precision, medium-power resistor that delivers reliable performance, accurate resistance, and long-term stability for a wide variety of electronic applications. Manufactured using Metal Oxide Film (MOF) technology, this resistor is ideal for circuits that require precision and consistent performance even in demanding conditions. Below is a detailed breakdown of its key features and potential applications:

Resistance Value (150K Ohms):

This resistor has a resistance of 150K ohms (150,000 ohms), making it suitable for circuits that require high resistance values, such as voltage dividers, signal conditioning, and input stages for analog circuits. The 150K ohm value is commonly used in sensor networks, audio circuits, and feedback loops for amplifiers or oscillators. Its precision ensures accurate voltage division and signal processing, especially in high-impedance applications.

Power Rating (1W or 1 Watt):

With a 1W (1 watt) power rating, this resistor can safely dissipate up to 1 watt of heat energy without compromising its performance. This makes it ideal for medium-power applications where moderate current is flowing through the resistor, including signal processing, feedback circuits, voltage regulation, and current limiting. The 1-watt power rating ensures that the resistor operates safely without excessive heat buildup, even under continuous or prolonged use.

Tolerance (1%):

The 1% tolerance means that the actual resistance value of the resistor will be within ±1% of the nominal value of 150K ohms. This level of accuracy is critical for precision circuits where even small variations in resistance can affect circuit performance. The 1% tolerance ensures that the resistor maintains its value within tight limits, making it ideal for measurement equipment, signal conditioning, and calibration circuits where precision is key.

Axial Through-Hole Mounting:

The axial through-hole design consists of two leads that extend from opposite ends of the resistor. These leads are designed to be inserted into PCB holes and soldered securely on the opposite side. The axial through-hole mounting offers a durable and easy-to-handle solution for soldering and installation. This type of resistor is commonly used in prototyping, DIY projects, and production environments due to its ease of handling, repair, and replacement.

Material and Durability – Metal Oxide Film (MOF):

This resistor is constructed using Metal Oxide Film (MOF), which provides several key advantages over standard carbon film resistors. MOF resistors are known for their high stability, low noise, excellent voltage resistance, and thermal performance. The MOF construction ensures the resistor can operate in demanding conditions without significant resistance drift, even under high temperatures or high-power loads. This makes it a preferred choice for long-term reliability in high-performance circuits.

Its precision ensures accurate voltage divisions, providing consistent signal levels for further processing or conversion.

• Signal Processing and Filtering: This resistor is ideal for signal conditioning and filtering applications, including audio, RF (radio frequency), and video circuits. It is often used in RC (Resistor-Capacitor) filters to control the frequency response, eliminate noise, or smooth signals. Its high precision ensures that the filter circuits operate correctly, making it suitable for high-fidelity audio systems and communication circuits.

• Biasing Networks: The 150K resistor plays a crucial role in biasing circuits for active components like transistors, operational amplifiers (op-amps), and other analog devices. In these circuits, the resistor helps set the proper operating point for the components, ensuring they function within their optimal performance ranges. This makes it essential for amplifiers, oscillators, and signal generators.

• Feedback Networks: This resistor is also used in feedback networks within amplifiers and oscillators, where it helps control the gain or frequency response of the circuit. The 150K value is often used in op-amp circuits, where precision feedback is necessary for maintaining the desired performance characteristics of the circuit.

• Power Regulation and Current Limiting: With a 1W power rating, this resistor is well-suited for current-limiting and power regulation circuits. It can be used to limit the current flow in circuits, preventing excessive current from damaging sensitive components. It also plays a role in voltage regulation circuits, ensuring that voltage levels remain within specified limits.

• Precision Instrumentation: Due to its 1% tolerance, this resistor is highly suitable for precision measurement circuits, including calibration instruments and signal generators. It ensures that scientific instruments, test equipment, and diagnostic tools provide accurate and stable readings over time, which is critical for high-accuracy applications.

Ease of Handling and Repair:

The axial through-hole design ensures that this resistor is easy to handle, install, and replace in both breadboard setups and PCBs. Its leads are long enough for secure connections, and the design allows for easy replacement if a component fails or needs upgrading. The through-hole mounting provides excellent mechanical strength, ensuring a reliable connection that is resistant to vibration and stress.
