FAQ

1. What is a 47 Ohm 1206 Package 1/4W SMD Resistor?

The 47 Ohm 1206 Package 1/4W SMD Resistor is a surface-mount resistor with a resistance value of 47Ω. It is housed in the 1206 (3216 Metric) package and features a 1/4W (0.25W) power rating, making it suitable for a wide range of low- to moderate-power electronic applications.

2. What are the common applications of a 47 Ohm 1206 SMD resistor?

A 47Ω resistor is commonly used for LED current limiting, signal termination, impedance matching, current limiting, RC filter circuits, power supply filtering, and general-purpose electronic circuit design.

3. What are the advantages of the 1206 package?

The 1206 package, measuring approximately 3.2mm × 1.6mm, offers better heat dissipation, higher power handling, improved mechanical strength, and easier manual soldering compared to smaller SMD packages, making it ideal for both prototyping and production.

4. What does the 1/4W power rating indicate?

The 1/4W (0.25W) power rating specifies the maximum amount of power the resistor can safely dissipate as heat during operation. This higher rating makes it suitable for applications requiring greater power handling than 0603 or 0805 package resistors.

5. Why is a 47 Ohm resistor widely used in electronic circuits?

The 47Ω resistor provides a low resistance value that is ideal for current limiting, signal damping, impedance matching, reducing switching noise, and protecting sensitive electronic components. Its 1206 package offers reliable performance, excellent durability, and easy PCB assembly, making it a popular choice for consumer electronics, industrial equipment, embedded systems, communication devices, and DIY electronics projects.
