The 747D series offers a low impedance over an extended temperature range of 55 C to 105 C.
With the high ripple current capability and the low impedance, the 747D is ideal for high frequency
SMPS output filtering applications. The 747D series capacitors also offer a long life under normal
operating conditions.

When ordering, always specify complete catalog number for 747D Series.
Lead Code: A = Low Post 10 - 32 Screw Thread (Standard ).
B = High Post 10 - 32 Screw Thread.
I = High Post M5 Screw Thread.
Case Style: 2 = PVC Sleeve.
Case Code: See Case Sizes in Tables.
DC Rated Voltage: Expressed in Volts. Zero proceeds the voltage rating
when less than 100 volts. An R indicates a decimal point (e.g. 6R3 = 6.3V ).
Capacitance Tolerance: M = 20%
Capacitance Value: Expressed in Microfarads. The first two digits are
significant figures, the third digit indicates the number of zeros.
