Description

The 51 Ohm 2W 5% Through Hole Resistor is a precision electrical component commonly used in electronic circuits to limit current flow, divide voltage, and provide a stable electrical resistance. It is designed for through-hole mounting, meaning it is intended to be inserted into a circuit board where the leads pass through the PCB (Printed Circuit Board) and are soldered on the opposite side.

Key Features:

• Resistance Value: The resistor has a resistance of 51 ohms (Ω), which determines its ability to resist the flow of electrical current. This value is ideal for specific applications where current limiting or voltage division is required.
• Power Rating: With a power rating of 2 watts (2W), this resistor can handle a maximum continuous power dissipation of 2 watts without damage, ensuring it is suitable for applications involving moderate power levels.
• Tolerance: The resistor offers a tolerance of 5%, which means the actual resistance can vary by up to 5% from the nominal value. This makes it suitable for general-purpose applications where precise resistance is not critical but still provides a good level of accuracy.
• Through-Hole Mounting: The resistor features leads designed for through-hole assembly, ensuring a secure and durable connection when soldered to a PCB. This is ideal for designs where the component will be exposed to mechanical stress or requires robust electrical connections.
• Durability and Reliability: The resistor is built to last, with a durable construction capable of withstanding environmental factors such as temperature variations and vibration. It is commonly used in power supplies, amplifiers, audio equipment, and other electronics that require stable resistance values under moderate electrical load.
• Application: This 51-ohm resistor is often used in circuits involving signal conditioning, current limiting for LEDs or transistors, voltage division, or as part of feedback networks. Its medium power handling capacity makes it well-suited for use in low to medium-power devices.
