What is the shelf life of electrolytic capacitors?
about 20 years
Can electrolytic capacitors, typically greater than 1 inch in length and diameter and used in power supplies, converters and inverters, should have a shelf life of about 20 years, based upon storage temperatures.
How do you date a capacitor?
The following are examples of typical date codes for United Chemi-Con products.
- N. (3) X.
- Year. Plant ( ) Day of Month. Month.
- X. N. (3)
- Year. Month. Plant ( ) Day of Month.
- Radial. EIA Date Code.
- L.
- Factory. Week Number. Last Two Digits of Year.
- N. X.
Are Nichicon capacitors any good?
Nichicon is a reputable company, so their audio capacitors are probably no worse than any others in their intended applications. I would, however, be wary of the more exotic brands that make only audio parts and don’t use the normal electronic component distributors (Farnell, Mouser, etc).
What is the date code on a Nichicon capacitor?
For example – I have the capacitor wit date code B1538. So it means it was manufactured at 2015 year and 38 week? And what the letter B means? The datasheet can be found here.
What is the capacitance tolerance of a Nichicon?
14 Configuration Package code Size code Capacitance tolerance (±20%) Rated capacitance (10µF) Rated voltage (16V) Series name Type φD 3 4 to 10 code 2 1 φD 3 to 8 (5.4L) 6.3 to 10 (L 5.8) code GB GS φD 3 to 8 (L 7.7) 8 to 10 (L = 10) code CL NL 1 Voltage Capacitance 105˚C Marking 105˚C Marking (φ3 to φ8 × 5.4 ) (φ8 × 10, φ10 × 10 ) A2P 10 16V
What is the part number for aluminum electrolytic capacitors?
ALUMINUM ELECTROLYTIC CAPACITORS CAT.8100J Trimmed (Cut) or Formed Leads Radial lead type In order to identify correct part number for the processed lead product, cut/formed lead code must be added to bulk part number.
How is the dielectric of an electrolytic capacitor controlled?
With aluminum electrolytic capacitors, since aluminum oxide has excellent withstand voltage, per thickness. And the thickness of dielectric can be freely controlled according to the rated voltage of the aluminum electrolytic capacitor.
