Shelf Life The following specifications shall be satisfied when the capacitors are restored to
20C after
exposing them for 1,000 hours at
105C without voltage applied. The rated voltage shall be
applied to the capacitors for a minimum of 30 minutes, at least 24 hours and not more than
48 hours before the measurements.
Capacitance change: ≤
15% of initial measured value
Tan (DF) : ≤ 150% of initial specified value
Leakage current : ≤ initial specified value
Endurance
(Load Life)
The following specifications shall be satisfied when the capacitors are restored to
20C after
subjecting them to DC voltage for 2,000 hours at
105C with the rated ripple current applied.
The sum of the DC voltage and peak AC voltage must not exceed the full rated voltage of
the capacitors.
Capacitance change: ≤
20% of initial measured value
Tan (DF) : ≤ 200% of initial specified value
Leakage current : ≤ initial specified value
Terminal Code: T2 = 2- Pin Snap-in (Standard ).
Case Code: See Case Sizes in Tables.
Capacitance Tolerance: M =
20%
Capacitance Value: Expressed in Microfarads. The first two digits are
significant figures, and the third digit indicates the number of zeros
for capacitance of 100F or more. R indicates the decimal point for
capacitance less than 100F (e.g. R15 = .15F; 1R5 = 1.5F;
15R = 15F; 151= 150F; 152 = 1,500F; 153 = 15,000F).
Lead Configuration: VS = 2-Pin Snap-in Terminals.
DC Rated Voltage: Expressed in Volts (e.g.180 = 180WVDC).
Series Name: Indicates Basic Capacitor Design.
Part Numbering System for KMQ Series When ordering, always specify complete catalog number for KMQ Series.
