How to read the date code on a relay
Introduction:
Date code / lot number is the number to identify when the component is being manufactured. It is for the factories
production quality control and tracing purposes.
Date code:
There are 3 different date code format on our relays:
1) Three digit code: The first digit represents the year and the remaining two digits represent the week number in a
calendar year, e.g. 451 means week 51 of year 2004.
2) Four digit code: The first two digits represent the year and the remaining two digits represent the week number in
a calendar year, e.g. 0451 means week 51 of year 2004.
3) Five digits code: The first digit represents the year. The second two digits represent the month and the remaining
two digits represent the day, e.g. 41201 means Dec. 1, 2004
Factory code:
A letter following the date code identifies factory location.
