Description

The 680K Ohm 1/4W 1% Through Hole Resistor is a high-precision, durable electronic component designed for use in various electronic circuits. It is a standard through-hole resistor, meaning it is intended to be mounted on a printed circuit board (PCB) with leads that pass through the board and are soldered on the opposite side.

Key Specifications:

• Resistance: 680,000 ohms (680KΩ), providing a specific resistance value for precise current control in your circuit.
• Power Rating: 1/4 watt (0.25W), meaning the resistor can safely dissipate up to 0.25 watts of electrical power without overheating or damage, making it suitable for moderate power applications.
• Tolerance: 1%, which indicates the precision of the resistor. A 1% tolerance means the actual resistance could vary by ±1% from the nominal value of 680KΩ, ensuring reliable performance in applications that require a high degree of accuracy.
• Package Type: Through hole, designed for easy insertion and soldering into a PCB. The leads are typically 0.5mm in diameter, fitting into standard holes for secure mounting.
• Construction: Made of a high-quality ceramic or plastic material, often with a metal oxide or carbon composition for stable and consistent resistance.
• Temperature Coefficient: Often rated around ±100 ppm/°C, meaning the resistance value will change by a small percentage for every degree of temperature change, ensuring its stability under different environmental conditions.

Applications:

This resistor is commonly used in precision electronics, signal processing circuits, voltage dividers, filtering, and as part of measurement or calibration systems where stability and accuracy are crucial. The 680KΩ resistance value makes it ideal for high-impedance applications such as high-frequency circuits, sensor networks, or analog signal conditioning.

Advantages:

• High Accuracy: With its 1% tolerance, it offers greater accuracy in circuit design, reducing variability and ensuring reliable performance.
• Compact Design: The through-hole design allows for easy handling and soldering, and it provides a robust physical connection to the PCB, which is especially useful in applications requiring reliability and durability.
• Versatile: Suitable for a wide range of applications in various industries, including telecommunications, automotive, consumer electronics, and more.

This resistor is an essential component for engineers, hobbyists, and professionals who require precise resistance values for their circuit designs. It provides a balance between performance, durability, and cost, making it a popular choice for many electronic projects.
