Cornell Dubilier Capacitors Series ALS41A154NP040

Product Details

Screw Terminal Aluminum Electrolytic Capacitors

ALS40/41 Series, +105°C


Overview

KEMET's ALS40/41  Series of screw terminal capacitors features the same high ripple currents and long-life characteristics as the ALS30/31 Series but can operate at higher temperatures. They are similarly suited for high reliability and long-life applications such as frequency converters, uninterruptible  power supply (UPS) systems, and switch mode power supplies (SMPS) but the extended temperature range allows increased ripple currents at lower temperatures.


Applications

Typical applications for KEMET's ALS40/41  Series of capacitors include smoothing, energy storage or pulse operation in telecommunication demanding power supplies, process control, frequency inverters, drives, traction, welding, and measuring.


Benefits

• Compact size

• Long life, up to 9,000 hours at +105°C (VR, IR applied)

• High ripple current

• Excellent surge voltage capability

• Optimized designs available upon request

Case Polarity

Due to the presence of electrolyte in the capacitor, the aluminum can and stud mounting will essentially be at the same polarity as the negative terminal. We recommend that the stud and can be insulated (see accessories for insulating nuts).


Terminations

Aluminum inserts with M5 threads as standard, maximum torque 2NM. Optional M6 threaded inserts have a maximum torque 4NM. Maximum torque for stud mounting M8:4NM and M12:8NM.


Shelf Life

The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods, however the leakage current will very slowly  increase.  KEMET products are particularly stable and allow a shelf life in excess of three years at 40°C. See sectional specification under each product series for specific data.


Re-age (Reforming) Procedure

Apply the rated voltage to the capacitor at room temperature for a period of one hour, or until the leakage current has fallen to a steady value below the specified limit. During re-aging a maximum charging current of twice the specified leakage current or 5 mA (whichever is greater) is suggested.


Reliability

The reliability of a component can be defined as the probability that it will perform satisfactorily under a given set of conditions for a given length of time.


In practice, it is impossible to predict with absolute certainty how any individual component will perform; thus, we must utilize probability theory. It is also necessary to clearly define the level of stress involved (e.g. operating voltage, ripple current, temperature and time). Finally, the meaning of satisfactory performance must be defined by specifying a set of conditions which determine the end of life of the component.


Reliability as a function of time, R(t), is normally expressed as: R(t)=e-λt

where R(t) is the probability that the component will perform satisfactorily for time t, and λ is the failure rate.


Failure Rate

The failure rate is the number of components failing per unit time. The failure rate of most electronic components follows the characteristic pattern:

• Early failures are removed during the manufacturing process.

• The operational life is characterized by a constant failure rate.

• The wear out period is characterized by a rapidly increasing failure rate.

The failures  in time (FIT) are given with a 60% confidence  level for the various type codes. By convention, FIT is expressed as

1 x 10-9 failures per hour. Failure rate is also expressed as a percentage of failures per 1,000 hours. e.g., 100 FIT = 1 x 10-7 failures per hour = 0.01%/1,000 hours


End of Life Definition

Catastrophic Failure: short circuit, open circuit or safety vent operation

Parametric Failure:

• Change in capacitance  > ±10%

• Leakage current > specified limit

• ESR > 2 x initial ESR value
