Electrolyte capacitors

EPCOS capacitors

TDK-EPCOS aluminum electrolytic capacitors have found wide application practically in all fields of electronics thanks to their advantages: :

  • High specific capacitance which allows to produce components with capacity up to 1 F;
  • Compact sizes at high values of nominal capacitance;
  • High ripple current;
  • High reliability;
  • Optimal ratio price/productivity.

Specific capacitance of Epcos electrolytic capacitors reaches practically a limited value. Like the rest capacitors they consist of two electrically conductive plates separated by a dielectric layer. electrolytic capacitor One of electrodes - anod - is made of Al foil with increased effective surface area and is covered by oxide layer (Al2O3). In order to increase a capacitance TDK (Epcos) has developed a special method of foil etching that increases effective surface area. Such foil allows to manufacture very compact electrolyte capacitors. A thickness of alumina layer is about 1 μF that determines a high specific capacitance of electrolytic capacities. Electrolyte (a conductive liquid) that is used as a cathode. Its main task is to fill all micropits on cathode and to effectively use its surface. Aluminum electrolytic capacitors TDK-EPCOS perfectly suit for application in industrial, consumer and automotive electronics. For comfortable using and mounting Epcos produces electrolytic capacitors with following types of terminals:

  • screw;
  • with 4-/5-pin snap-in terminals and solder pins;
  • snap-in;
  • axial-lead;
  • soldering star capacitors;
  • single-ended

Capacitors with screw terminals


screw
Capacitors with screw terminals are designed for operating in high current circuits and provide the best connection between capacitor and terminals. They are more stable to vibration due to rigid fixing on circuit board. Furthermore, additional heat rejection is realised through a screw connection that is extremely useful in harsh temperature conditions. EPCOS also offers special versions of capacitors for heat rejection.

Voltage range 16…100; 200…500; 500 V
Load current range 34…110 А
Capacity range 820…33000; 1500…330000 μF

Not long ago TDK (Epcos) has represented three new series of electrolytic capacitors with screw terminals with longer useful life (up to 12000 hours) at Maximal working temperature 85°С:
  • Capacitors series B43703** is characterised by CR=1500μF ... 22000μF. The sizes of this components are decreased on 20% comparing to previous series at the same current-carrying capacity.
  • Capacitors B43704** have a higher values of high ripple current (on 25%) comparing to and are characterised by small sizes. Components of this series can be used at VR=350V ... 550V DC и СR=820μ ... 22000μ.
  • Current-carrying capacity of series B43705* has been increased on 40% comparing to previous series saving compact sizes, VR=350V ... 450V DC, and СR=1000μF ... 18000μF.
  • Capacitors B43723**, B43724** and B43725** have an dditional advantage - fastening with a stud on a base.

Single-ended capacitors


large-size
Standard series of single-ended EPCOS capacitors is represented by two types of components: capacitors of general application and high-reliable capacitors for Automotive electronics. Capacitors for Automotive electronics are characterised by a small rejection during useful life and large current capability that allows them to operate at 135 °C. The series of capacitors for general application is represented for opeating at large voltage. That'a why this series include capacitors with working voltage up to 450V.
