Understanding Capacitor Designations: Unraveling the Mystery of 104K

When working with electronics, capacitors are an essential component in many circuits. However, deciphering the codes and designations on these tiny components can be a daunting task, especially for beginners. In this article, we'll delve into the world of capacitor designations, focusing on the specific code "104K" found on non-electric electrolytic capacitors.

What do the numbers and letters mean?

The designation "104K" consists of three parts: the number "104" and the letter "K". Let's break down each component to understand its significance:

The Number: 104

In capacitor designations, the number "104" represents the capacitance value in picofarads (pF). To decode this, we need to know that the first two digits (10) represent the significant digits, and the third digit (4) represents the multiplier.

  • 10 = significant digits (10)
  • 4 = multiplier (10^4)

Using the multiplier, we can calculate the capacitance value:

10 x 10^4 = 100,000 pF

To convert this value to more familiar units, we can express it in terms of microfarads (μF):

100,000 pF ≈ 100 μF

So, the capacitance value of this capacitor is approximately 100 μF.

The Letter: K

The letter "K" represents the tolerance rating of the capacitor. Tolerance refers to the allowed variation in capacitance value from the specified value. In this case, "K" indicates a tolerance of ±10%.

This means that the actual capacitance value of the capacitor can vary by up to 10% from the specified value of 100 μF. For example, the actual value could be anywhere between 90 μF and 110 μF.

In Summary

The non-electrolytic capacitor with the designation "104K" has a capacitance value of approximately 100 μF with a tolerance of ±10%. When working with capacitors, it's essential to understand these designations to ensure that you're using the correct component in your circuit.

By deciphering the codes and understanding the values, you'll be better equipped to navigate the world of electronics and design more accurate and efficient circuits.
