Default Nippon Chemi-con date codes

Does anyone know how to decode a date code for a Nippon-Chemicon electrolytic?

Othe than the KMH series, voltage, and capacitance, I have some having "40c14L 72" on the label. Can anyone decipher?

Found that one, but it doesn't seem to work, as the date codes are not in that format. Thanks.

Found out how to decipher date code for Nippon Chemi-cons:

First digit is the year

Second digit is the month: 1-9 and O-N-D

third digit is the day: A-Z and a-e

the next digit or two is the factory line

the next is the factory: L = Lansing

then comes the lot #

so for "40c14L 72":

date: 2004, Oct 29

factory line: 14

factory: Lansing

lot #: 72

Don't know how they distinguish 1994, 2004, or 2014, unless they add another digit. Factory tech didn't know, but didn't think KMH series was around in 1994.

Did you ever figure it out...

I just bought some KMH series Snap In caps
15,000 Uf 63 V with a date code 65F04L

Could it be 1996 - 2006 ? ? 5th month
Guess Lansing factory
