B43700. New 600V High Voltage Aluminum Electrolytic Capacitors from TDK

06/01/2022

B43700 series

The range of electronic components the new B43700 series of aluminum electrolytic capacitors with screw terminals from TDK is introduced. The series complements the series of capacitors of this type , which together can meet the needs of electrolytic capacitors with screw terminals for various operating conditions and applications.

Capacitors of the B43700 series are distinguished by high reliability and high maximum allowable ripple current, small size, all-welded design, providing reliable electrical contact. Among the design features, one can distinguish - an aluminum case covered with an insulating film, terminals for a screw, installation using ring clamps or clamps. The capacitors themselves are polar, with charge-discharge protection.

All capacitors in the series can be used up to a maximum temperature of + 85 ° C at a rated voltage of 600V (DC), the rated capacity, depending on the model, is from 1000uF to 6800uF.

Most often, aluminum electrolytic capacitors with screw terminals are used in industrial electronics applications - frequency converters, renewable energy sources (based on wind turbines and solar panels), uninterruptible power supplies, medical applications, switching power supplies in professional equipment, etc. 

Dimensions and marking of the positive polarity terminal:

B43700

The maximum permissible ripple current is determined by the diameter of the capacitor, and due to the limited area of ​​the contact elements, the ripple current should not exceed the value:

B43700
