SMD Capacitor Code Chart: A Comprehensive Guide

What is an SMD Capacitor?

A Surface Mount Device (SMD) capacitor is a type of capacitor that is mounted directly onto the surface of a printed circuit board (PCB). SMD capacitors are widely used in electronic devices due to their small size, low profile, and high reliability.

Understanding SMD Capacitor Codes

SMD capacitors have a unique code printed on them to identify their characteristics. The code consists of a combination of letters and numbers that indicate the capacitor's capacitance, tolerance, and voltage rating.

Example of an SMD Capacitor Code

Let's take an example of an SMD capacitor with the code "104K5R5". Here's what each part of the code means:

  • 104: Capacitance code, which corresponds to a capacitance value of 100nF (100,000pF).
  • K: Tolerance code, which indicates a tolerance of ±10%.
  • 5R5: Voltage rating code, which corresponds to a voltage rating of 5.5V.

Conclusion
