Nemco Electronics Marking User Manual
Marking, C4μ7, Date code system

Nemco surface mount tantalum capacitors are marked by laser on the top surface. The positive (+) end of the body has a
videcon readable bar marking for improved polarity identification. Space permitting, with the exception of MCT miniature
surface mount series, marking shall consist of:
l
Capacitance in
μfd
l
Voltage or voltage code (+85°C Vr)
l
Polarity Bar (+)
l
Date Code (Not available on: TB, CGT, MCT, PCT XL case size, LSR XL case size)
Case Sizes C, CL, D, DL, H, Z
Radial dipped tantalum capacitors are marked by laser
on the capacitor body. The positive (+) lead of the
capacitor has a polarity stripe for improved recognition.
Marking
Case Size P, R
Maximum ESR ratings in milliohms is
marked only for case sizes C, D and H.

The Nemco date code uses a two character system.
The first character defines the year of manufacture.
The second character defines the month of manufacture.
examples: W3 = March 2008
VN = November 2007
