TER
Taping Code: TER is standard.
Engineering Bulletin Jul 03
When ordering, always specify complete catalog number for PTB Series.
ESR Code: ESR rating is included in parentheses in the part number only
to identify one part from another when two or more capacitors are the
same size and have the same capacitance and voltage rating.
Case Code: Refer to diagram of dimensions for standard case sizes.
Capacitance Tolerance: M = 20%
Capacitance Value: Expressed in Picofarads. The first two digits are
significant figures, and the third digit indicates the number of zeros
following these figures ( e.g. 477 = 470,000,000pF = 470 F ).
Series Name: Indicates Basic Capacitor Design.
DC Rated Voltage: Expressed in Volts (e.g. 4 = 4WVDC).
(Note: 2R5 = 2.5WVDC and 6 = 6.3WVDC).
