A 390K Ohm 1W 5% Through Hole Resistor is an electronic component used to limit or control the flow of electric current in a circuit. With a resistance value of 390,000 ohms, this resistor provides a specific level of opposition to the flow of current, making it ideal for various applications where a precise resistance is required to achieve the desired electrical performance.

Key specifications:

• Resistance Value: 390K Ohms (390,000 ohms), which is suitable for a range of applications that require higher resistance values to protect circuits or set specific current limits.
• Power Rating: 1 watt (W), indicating the maximum amount of power the resistor can safely dissipate without being damaged. This power rating ensures it can handle moderate electrical loads, commonly found in both consumer and industrial applications.
• Tolerance: 5%, which refers to the permissible deviation from the nominal resistance value. In this case, the actual resistance can vary by up to 5% of the stated value, allowing for some flexibility in design and ensuring the resistor meets a wide range of standard specifications.
• Type: Through-hole mount, meaning it is designed to be inserted into holes on a printed circuit board (PCB) and soldered in place. This mounting type is widely used for its reliability and ease of installation in both prototypes and mass production.
• Material: Typically made from a metal oxide or carbon film, this resistor is constructed to handle the specified power rating and tolerance, ensuring stable performance over time in different environmental conditions.
• Applications: This resistor is commonly used in various electrical and electronic devices, including amplifiers, filters, voltage dividers, and current-limiting circuits. It is ideal for use in both consumer electronics, like audio equipment and power supplies, and industrial applications that require precise resistance values to function safely and efficiently.
• Size and Packaging: The physical dimensions of the resistor are typically standardized for through-hole components, allowing it to fit into most PCB designs and ensuring easy soldering.

This 390K Ohm 1W 5% Through Hole Resistor offers a reliable solution for designing circuits with accurate current control, making it an essential component in electronics design and development.
