4.7K Ohm (4.7K) 1W 1% Axial Through Hole Resistor - MOF

The 4.7K Ohm (4.7K) 1W 1% Axial Through Hole Resistor - MOF is a high-precision, medium-power resistor designed for applications that require accuracy, durability, and reliable power dissipation. With its Metal Oxide Film (MOF) construction, this resistor offers excellent heat resistance and long-term stability, making it suitable for use in high-precision circuits, signal conditioning, and power regulation tasks. Here’s a detailed breakdown of its features:

Resistance Value (4.7K Ohms):

This resistor has a resistance of 4.7K ohms (4700 ohms), making it a common choice for many applications where moderate to high resistance is needed. It's particularly useful for voltage divider networks, filter circuits, and signal processing, providing excellent control over current flow in circuits that require stable impedance levels, such as audio equipment, analog sensors, and voltage regulation circuits.

Power Rating (1W or 1 Watt):

The 1W (1 watt) power rating indicates that the resistor can safely dissipate up to 1 watt of power as heat. This is well-suited for medium-power applications, where higher current may flow through the resistor but heat buildup needs to be managed. It is ideal for signal processing, biasing networks, and feedback loops where moderate current handling is required without overheating.

Tolerance (1%):

With a 1% tolerance, this resistor is highly accurate. This means that the actual resistance value will be within ±1% of the nominal 4.7K ohms. The 1% tolerance is ideal for precision work in circuits that need tight regulation of current and voltage, such as sensor interfacing, analog signal processing, calibration circuits, and high-performance amplifiers.

Axial Through-Hole Mounting:

This resistor features an axial through-hole design, where it has leads that extend from either end of the resistor body, making it easy to insert into printed circuit board (PCB) holes and solder. The axial design is commonly used in both DIY and professional applications, offering robust electrical connections that are both durable and easy to repair or replace when necessary. It’s especially beneficial in prototyping and testing, where flexibility and ease of handling are essential.

Material and Durability – Metal Oxide Film (MOF):

Made from metal oxide film (MOF), this resistor provides exceptional stability, heat resistance, and durability. MOF resistors typically exhibit lower noise, better high-voltage resistance, and greater long-term stability compared to carbon film resistors. This makes them ideal for high-precision and high-reliability applications, where consistent performance and minimal drift are essential, such as in measurement instruments and audio circuits that demand accuracy over extended periods.

Applications:

• Voltage Divider Networks: The 4.7K resistor is commonly used in voltage dividers to create specific voltage levels for sensors, signal conditioning, and microcontroller interfacing. Its accuracy ensures that voltage outputs remain stable and within the desired range for the circuit to function correctly.

• Signal Processing and Filtering: Perfect for use in signal processing circuits, especially in audio, radio frequency (RF), and video applications where precise impedance matching, filtering, and voltage regulation are required.

• Biasing Networks: Used in transistor biasing and op-amp circuits, the 4.7K resistor helps set the appropriate voltage levels and current paths for stable operation, making it key to ensuring the proper performance of amplifiers and oscillators.

• Feedback Loops: Essential in feedback networks of amplifiers and oscillators where precise resistance is required to maintain the desired gain or frequency response. The 1% tolerance ensures tight control over circuit behavior.

• Power Regulation: The resistor can also play a role in power regulation circuits by controlling the current flow, especially in voltage regulators, current-limiting circuits, and over-voltage protection.

• Precision Instrumentation: With its 1% tolerance, the resistor is ideal for use in calibration circuits and measurement equipment, where small variations in resistance can impact the accuracy of the system. It ensures that instruments deliver consistent and accurate readings.

Ease of Handling and Repair:

Thanks to its axial through-hole mounting, this resistor is easy to handle, solder, and replace, making it an excellent choice for both prototyping and repair work. The leads are long enough to allow for flexibility when adjusting or repositioning components on a breadboard or PCB. Its design makes it easy to work with, especially in environments where frequent modifications are needed.

In Summary:

The 4.7K Ohm (4.7K) 1W 1% Axial Through Hole Resistor - MOF is a high-precision, medium-power resistor that combines accurate resistance with 1% tolerance and 1W power handling. The Metal Oxide Film (MOF) construction ensures durability, heat resistance, and stability, making it suitable for a wide range of applications, including voltage dividers, signal processing, biasing networks, feedback loops, and power regulation. Whether you're working on calibration, audio circuits, or precision instrumentation, this resistor offers consistent and reliable performance in high-accuracy designs.
