Notes
• We reserve the right to supply higher voltage ratings and tighter capacitance tolerance capacitors in the same case size.
Voltage substitutions will be marked with the higher voltage rating
• The EIA and CECC standards for low ESR solid tantalum chip capacitors, allow delta ESR of 1.25 times the datasheet limit after mounting
• Dry pack as specified in J-STD-033

Marking
Capacitor marking includes an anode (+) polarity band, capacitance in microfarads and the voltage rating. “A” case capacitors use a letter
code for the voltage and EIA capacitance code.
The Vishay identification marking is included if space permits. Vishay marking (“circled 2”) may show additives in the form of short lines,
depicting actual manufacturing facility. For A case capacitors discontinuation in polarity bar maybe used as actual manufacturing facility
designation. Capacitors rated at 6.3 V are marked 6 V.
A manufacturing date code is marked on all capacitors, for details see FAQ:
www.vishay.com/doc?40110.
Capacitors may bear TP3 marking scheme if parts are substituted with high performance automotive grade TP3 family products.
This includes, for example, letter “P” as shown below.
Call the factory for further explanation.
