1. What is a Capacitor Code Calculator?

Definition: This calculator decodes the numerical markings on ceramic capacitors to determine their capacitance in picofarads (pF).

Purpose: It helps electronics engineers, technicians, and hobbyists quickly determine capacitor values without memorizing codes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Capacitance in picofarads (pF)
• \( digit1 \) — First digit of the code (0-9)
• \( digit2 \) — Second digit of the code (0-9)
• \( multiplier \) — Power of ten multiplier (-2 to 9)

Explanation: The first two digits form a significant number which is multiplied by 10 raised to the multiplier value.

3. Importance of Capacitor Code Calculation

Details: Correct interpretation of capacitor codes ensures proper component selection for circuits, preventing malfunctions or damage.

4. Using the Calculator

Tips: Enter the two-digit code and multiplier from the capacitor marking. Common multipliers range from 0 to 6 for most ceramic capacitors.

5. Frequently Asked Questions (FAQ)

Q1: What does a code like "104" mean?
A: 104 means 10 × 10^4 pF = 100,000 pF or 100nF (digit1=1, digit2=0, multiplier=4).

Q2: What about codes with letters?
A: This calculator handles numeric codes only. Letters often indicate tolerance or voltage rating.

Q3: What's the range of this calculator?
A: It can calculate from 0.01pF (digits 00, multiplier -2) up to 99,000,000,000pF (digits 99, multiplier 9).

Q4: How do I read small capacitors?
A: Use a magnifying glass. The code is typically printed very small on ceramic capacitors.

Q5: What if my capacitor has only one digit?
A: Enter the single digit as digit1 and 0 as digit2, then the appropriate multiplier.
