Description

A 1K Ohm 1/4W 1% Through Hole Resistor is a standard passive electronic component designed to limit the current flow in a circuit by providing a specified amount of resistance. Here’s a detailed breakdown of its characteristics:

1. Resistance Value (1K Ohm): This resistor has a resistance of 1,000 ohms (1K), which determines how much it resists the flow of electrical current. The resistance value is typically measured in ohms and represents the opposition to current in an electrical circuit.

2. Power Rating (1/4W): The resistor has a power rating of 1/4 watt (0.25W), meaning it can safely dissipate a maximum of 0.25 watts of electrical power without overheating. If more power is applied, the resistor may get damaged or even fail.

3. Tolerance (1%): This resistor has a tolerance of 1%, meaning the actual resistance can vary by 1% from the nominal value (1K ohm). For example, a 1K ohm resistor with 1% tolerance could have an actual resistance anywhere between 990 ohms and 1,010 ohms. This is important for applications where precision is necessary but a small variance is acceptable.

4. Through Hole Mounting: This resistor is designed for through-hole mounting, meaning it has leads (wires) that go through holes in a printed circuit board (PCB). After insertion, the leads are soldered to secure the resistor in place. This type of mounting is often used in applications where the components are placed manually or for prototyping.

5. Standard Size and Construction: The resistor typically comes in a small cylindrical package, often referred to as a "axial" resistor, where the leads are positioned at both ends. The body is usually made of ceramic or other non-conductive materials and coated with a colored band that indicates its resistance value and tolerance. The 1K Ohm 1/4W 1% resistor is generally used in low- to medium-power applications such as signal processing, voltage division, and current-limiting.

6. Applications: Common uses for this resistor include audio equipment, power supply circuits, LED applications, and signal processing systems. It is ideal for applications that require precision with a tolerance of 1%, such as voltage dividers, filters, or low-impedance signal conditioning.

7. Durability and Quality: This resistor is designed to endure the electrical and mechanical stresses of everyday use in various electronic devices. The 1% tolerance and 1/4 watt rating make it suitable for more sensitive and precise applications where the resistor must maintain consistent performance under normal operating conditions.

In summary, the 1K Ohm 1/4W 1% Through Hole Resistor is a reliable, precise, and durable component, widely used in electronic circuits for various applications requiring accurate resistance values and safe power dissipation. Its through-hole design allows for easy integration into traditional PCBs, making it a versatile choice for hobbyists, engineers, and manufacturers alike.
