3.3 Ohm SMD Resistor

Description

The 3.3 Ohm SMD Resistor is a surface-mount electronic component designed for printed circuit board (PCB) applications. It is listed with a nominal resistance of 3.3 ohms and is intended for electronic circuits that require this resistance value.

Resistors are important components in electronic systems. They help control current, divide voltage, adjust signal levels, and establish suitable operating conditions for other circuit components. Choosing the correct resistance value and electrical rating helps ensure compatibility with the intended circuit.

Resistance Value

This product is listed as a 3.3-ohm SMD resistor. It may be suitable for circuit designs that specifically require a resistance of 3.3 ohms. Its suitability depends on the circuit’s operating voltage, expected current, power dissipation, and other component requirements.

Please verify the actual resistance value using the manufacturer’s datasheet or product marking before installation. The supplied description mentions 3.3K ohms, which is different from 3.3 ohms.

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 mounting method supports compact electronic layouts and automated PCB assembly.

Surface-mount resistors are commonly used in electronic control boards, industrial equipment, measuring instruments, communication devices, and general-purpose electronic assemblies.

Package Size

The supplied product category identifies this item as a 1206 package SMD resistor, while the product description mentions a 0603 package. These package sizes have different physical dimensions and are not directly interchangeable without checking the PCB footprint.

Confirm the actual package size with the manufacturer before publishing final specifications or placing an order. The package size should match the intended circuit board and assembly requirements.

Resistance Tolerance

The supplied feature list mentions tolerance options of ±0.5% and ±1%. Resistance tolerance describes the permitted variation from the nominal resistance value.

The exact tolerance available for this product should be confirmed against the manufacturer’s documentation. Do not assume that every tolerance option is available for every resistance value or package.

Stability and Construction

The source lists an overall stability class of 0.5 and IECQ-CECC approval to EN 140401-801. These specifications should be verified against the datasheet for the exact component before being presented as confirmed product characteristics.

The actual construction, operating stability, and reliability depend on the manufacturer’s design and specifications.

Power Rating

The supplied feature list states a rated dissipation of up to 0.4 W at 70°C for the 1206 package size. This rating should not be applied to the product until its package and datasheet are confirmed.

When selecting a resistor, consider resistance, power dissipation, operating temperature, working voltage, and the electrical requirements of the circuit. Using a component outside its specified limits may affect circuit performance.

Sulfur Resistance

The source states that sulfur resistance is verified according to ASTM B 809. This property can be relevant in environments where sulfur-containing compounds may affect component terminations. Confirm that the claim applies to the exact resistor being supplied.

Applications

SMD resistors are used in a broad range of electronic applications, including:

• Industrial electronic equipment
• PCB-based control circuits
• Electronic measuring instruments
• Communication equipment
• Current-control and signal circuits
• General-purpose electronic assemblies

The suitability of this 3.3-ohm resistor depends on the circuit design and the verified specifications of the component.

Installation Guidelines

Before installation, confirm the resistance value, package size, tolerance, power rating, and other relevant electrical limits. Use a compatible PCB footprint and follow the manufacturer’s soldering and handling recommendations.

When replacing an existing resistor, compare the complete specifications of both components. Matching the nominal resistance alone does not guarantee that the replacement is electrically or physically compatible.

Product Summary

The 3.3 Ohm SMD Resistor is listed for surface-mount electronic applications requiring a nominal resistance of 3.3 ohms. However, the supplied product information contains conflicting resistance and package details: the heading states 3.3 ohms, the description mentions 3.3K ohms and a 0603 package, and the category identifies a 1206 package.
