Learn about the use of surface mount resistors in modern electronics, including their installation, functionality, and applications in circuit design.
The purpose of this experiment is to understand the application and behavior of surface mount resistors in a circuit. We will explore their usage in a simple circuit and compare their performance with through-hole resistors.
Surface mount resistors are widely used in modern electronics due to their small size, which allows for higher component density and better performance at high frequencies. They are soldered directly onto the PCB, eliminating the need for leads that through-hole components require.
1. If using a PCB, solder the surface mount resistor (0603) onto the designated pads. If using a breadboard, prepare an SMD adapter.
2. For the through-hole resistor, insert it into the breadboard.
3. Connect the resistors in series with the power supply and the multimeter to measure voltage across each resistor.
Record the voltage drops across both types of resistors. Discuss any differences in performance, thermal properties, or ease of use between the surface mount and through-hole resistors.
This experiment demonstrates the application of surface mount resistors in electronic circuits. By comparing them with through-hole resistors, we observe the benefits of size, performance, and ease of integration into modern PCB designs. Surface mount resistors are essential for compact, efficient circuit designs.
