Nemco Electronics Marking - Manual

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.

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
