Description

A 220K Ohm 2W 5% Through Hole Resistor is an electronic component designed to limit or control the flow of electrical current in a circuit. It is a fixed resistor, which means it provides a constant resistance value of 220,000 ohms (220K Ohms) regardless of the applied voltage or the amount of current flowing through it.

Key Features:

• Resistance Value: 220,000 Ohms (220K Ω). This high resistance value makes it suitable for use in circuits requiring significant current limitation.
• Power Rating: 2 Watts (2W). This specifies the maximum amount of electrical power the resistor can safely dissipate without being damaged. A 2W resistor is appropriate for circuits where moderate power levels are involved, providing effective current limiting without overheating.
• Tolerance: 5%. The tolerance indicates the maximum deviation from the nominal resistance value. In this case, the resistor’s actual resistance could vary by up to 5% from the stated 220K Ohms, meaning it could fall within a range of 209K to 231K Ohms.
• Through Hole Mounting: This resistor features through-hole leads, meaning it is designed to be inserted through holes in a circuit board and soldered in place. This makes it a versatile component for both prototyping and finished circuit designs.
• Applications: This type of resistor is commonly used in analog signal processing, voltage divider circuits, audio equipment, power regulation circuits, and other general-purpose electronic applications where precise current control is necessary.

Construction and Materials:

The resistor is typically made from a ceramic or metal oxide core, which is coated with a resistive material. The leads are often made of tinned copper to ensure good electrical conductivity and solderability. The through-hole design is ideal for use in traditional PCB (Printed Circuit Board) designs and is compatible with standard assembly methods.

Durability and Reliability:

With a power rating of 2W, this resistor is capable of enduring relatively high levels of heat without failing, making it suitable for moderate power applications. It also features a 5% tolerance, which is a common industry standard for general-purpose resistors, offering a balance between performance and cost.

Summary:

The 220K Ohm 2W 5% Through Hole Resistor is a durable, reliable, and versatile component, ideal for applications where moderate power dissipation and a high resistance value are needed. It is suitable for use in various electronic circuits, offering good tolerance for most common applications requiring a consistent resistance value.
