Type AFK_V, –55 °C to 105 °C, High Vibration

SMT Aluminum Electrolytic Capacitors - Lowest E.S.R., 105 °C

Low Impedance and Long-Life for Filtering, Bypassing and Power Supply Decoupling

Using a ruggedized construction, type AFK_V withstands a 30 G

vibration test and has 40ꢀ to 60ꢀ lower impedance, 30ꢀ to 50ꢀ

smaller case size and more than twice the life compared to general

purpose types. As the main countermeasure to vibration, the metal

case is inserted into a molded plastic retaining wall that surrounds

the part, keeping it ﬁrmly in place. Larger diameter leads provide

additional mechanical stability of the internal winding and a larger

soldering surface keeps the part ﬁrmly aﬃxed to the PCB. Type

AFK_V is an excellent choice for power systems subjected to frequent

motion and vibration.

Highlights

• Withstands 30 G vibration test

• +105 °C, Up to 5000 ꢂour Load Life

• Capacitance Range: 10 µF to 6800 µF

• Voltage Range: 6.3 Vdc to 100 Vdc

Capacitors with the high vibration base will pass a 30 G acceleration test from 5

ꢂz to 2000 ꢂz with a max. amplitude of 5 mm (peak to peak) for 2 hours each in

the X,Y and Z directions for a total of 6 hours. During the last 30 minutes of the

test, the measured capacitance shall be stable. After the test the capacitor shall

meet the following:

High Vibration Test

∆C at 120 Hz - Capacitance value will be within 5ꢀ of the initial value.

There will be no signiﬁcant change in appearance.

RoHS Compliant
