Frequently asked questions
How do I read the 105J code?
The first two digits are significant figures (10) and the third is the multiplier (10^5 pF). So 10 × 10^5 pF = 1,000,000 pF = 1 µF, and J means ±5% tolerance.
Can I use it on AC mains?
Only if it is rated for AC. A 400 V rating is usually a DC rating, so for mains use select a capacitor specified as X2 class and check its datasheet.
