Description

The 2.2 Ohm SMD Resistor is a surface-mount electronic component designed for printed circuit board (PCB) applications. It provides a nominal resistance of 2.2 ohms and is intended for electronic circuits that require this resistance value.

Resistors are essential components in electronic systems. They help regulate current flow, divide voltage, adjust signal levels, and establish operating conditions for other electronic components. Selecting a resistor with the correct resistance and electrical ratings is important for circuit compatibility and reliable operation.

Resistance Value and Marking

This product is listed as a 2.2-ohm resistor. Common resistor marking codes for this value include 2R2 and 2E2, depending on the marking convention used. Always check the component marking and manufacturer’s datasheet to confirm the actual resistance.

The 2.2-ohm resistance value may be used in circuit designs that specifically require low resistance. Its suitability depends on the circuit configuration, current, voltage, power dissipation, and the requirements of connected components.

Surface-Mount Design

SMD stands for Surface-Mount Device. SMD resistors are designed to be mounted directly onto compatible pads on a printed circuit board. This construction supports compact circuit layouts and is suitable for automated electronic assembly.

Surface-mount resistors are widely used in industrial electronics, electronic control boards, communication devices, measuring instruments, and other PCB-based equipment.

Package Size

The supplied product image and category identify this item as a 1206 package SMD resistor. However, the product description mentions a 1210 package. These package sizes have different physical dimensions and should not be treated as interchangeable without checking the PCB footprint.

Confirm the actual package size with the manufacturer before ordering or publishing final specifications. The correct package must match the board layout and assembly requirements.

Fixed Resistance

A fixed resistor is designed to provide a specified nominal resistance rather than being adjusted during normal operation. Fixed resistors are used in circuits where a defined resistance is required for current control, voltage division, signal conditioning, or other electrical functions.

The actual performance of a resistor depends on its tolerance, power rating, operating temperature, and other manufacturer specifications. These details should be checked before selecting the component for a particular circuit.

Applications

Depending on the verified specifications and circuit design, a 2.2-ohm SMD resistor may be considered for:

  • Electronic control boards
  • Industrial electronic equipment
  • Current-control circuits
  • Signal and interface circuits
  • PCB-based electronic assemblies
  • General-purpose electronic applications requiring 2.2 ohms

These are general application areas for resistors, not a guarantee that this particular component is suitable for every listed use.

Electrical Compatibility

Before installing the resistor, verify its nominal resistance, tolerance, package size, power rating, working voltage, and operating-temperature limits. A resistor with the correct resistance may still be unsuitable if its power rating or physical dimensions do not meet the circuit requirements.

For replacement applications, compare the manufacturer’s specifications with those of the original component. Do not rely on resistance value alone to establish compatibility.

Installation Guidelines

Use a compatible PCB footprint and follow the manufacturer’s recommended soldering and handling procedures. Ensure that the resistor is installed in a circuit that operates within its specified electrical limits.

If the product’s marking or package is unclear, verify it using the datasheet or supplier documentation before installation. This is particularly important because the supplied information contains conflicting package-size details.

Product Summary

The 2.2 Ohm SMD Resistor is listed as a fixed surface-mount resistor for PCB applications requiring a nominal resistance of 2.2 ohms. The source identifies possible markings as 2R2, 2E2, or 2.2 Ohm.

The package size requires confirmation because the product image and category indicate 1206, while the description states 1210. Tolerance, power rating, working voltage, and other electrical specifications were not provided in the supplied product details.
