I am trying to repair a device that was handed to me. It has a broken tantalum capacitor with a missing lead, so it needs replacement. However I'm having trouble identifying its capacitance, voltage etc. I believe it's a KEMET T494 series but I can't say for sure. The markings on the capacitor are 'E105'. Does anyone have any ideas?
"105" usually means 10 pF x 100000. The "5" parts represents the number of zeros in the multiplier. "104" would be 100 nF. "103" would be 10 nF and "102" would be 1 nF.
Many companies use "E" to symbolize 25 volts and, as an example I've seen "A" used to represent 4.0 volts, B to represent 6.3 volts, C to represent 10 volts, D to represent 15 (or sometimes 16) volts hence, E represents 25 volts.
But, there are other code systems for the capacitor's voltage rating such as this: -
However, and luckily, E represents 25 volts in both systems. Another system that also uses "E" to represent 25 volts: -
