3K3 5% 0805 Chip Resistor: An Overview

Resistors are pivotal in electronic circuits, performing a variety of functions that are crucial for the proper operation of devices. Among these, the 3K3 5% 0805 chip resistor stands out due to its specific resistance value, size, and tolerance. In this blog, we will explore the characteristics, specifications, applications, and advantages of the 3K3 5% 0805 chip resistor, shedding light on why it is a common choice in modern electronics.

Decoding the Designation: 3K3 5% 0805 Chip Resistor

To understand the significance of the 3K3 5% 0805 chip resistor, it’s helpful to break down its designation:

• 3K3: This indicates the resistance value, which is 3,300 ohms (or 3.3 kilo-ohms).
• 5%: This specifies the tolerance, meaning the actual resistance can vary by ±5% from the nominal value.
• 0805: This refers to the size of the resistor, with dimensions of 0.08 inches by 0.05 inches.

Specifications and Features

The 3K3 5% 0805 chip resistor is a surface-mount device (SMD), designed for automated placement on printed circuit boards (PCBs). Its small size and robust construction make it ideal for various electronic applications. Key specifications include:

• Resistance Value: 3,300 ohms
• Tolerance: ±5%
• Power Rating: Typically 0.125 watts (1/8 watt)
• Temperature Coefficient: Commonly around ±100 ppm/°C
• Size: 2.0 mm x 1.25 mm

These specifications ensure that the resistor can handle moderate power levels while maintaining performance within the specified tolerance range.

Understanding Tolerance

The 5% tolerance means that the actual resistance can deviate by up to 5% from the stated 3.3K ohms. This implies that the resistor’s value could range between 3.135K and 3.465K ohms. While this variation might seem significant, it is generally acceptable for many applications where precise resistance is not critical. For high-precision requirements, resistors with tighter tolerances (such as 1% or 0.1%) would be more appropriate.
