Supercapacitors

Eaton is an international company that specialises in the design and manufacture of equipment and components for a variety of industries, including telecommunications, automotive, medical, defence and aerospace. An important division of Eaton includes electronic components such as power and EMC magnetics solutions, overvoltage and overcurrent circuit protection, supercapacitors, sensors and terminal blocks products which are used in a multitude of applications, including power supply for telecommunications systems, automotive safety systems, medical devices, etc. The company is certified under the ISO 9001 Quality Assurance System. International awards and certificates are clear evidence that the products developed by Eaton meet the latest safety standards and quality requirements. What is more, Eaton manufactures the Bussmann™ series of products which include fuses and protection devices.

Capacitors are some of the most common electronic components. They belong to the group of passive components, whose function is to store electrical energy. This process is carried out using two plates separated by a dielectric, in the electric field of which the energy is stored. The Eaton product range includes a rather specific type of capacitors – supercapacitors. They are a variation of electrolytic capacitors and are capable of storing large amounts of energy. Supercapacitors combine the characteristics of regular capacitors and rechargeable batteries, charging speed being their remarkable advantage. TME offers supercapacitors with capacitance ranging from 100 mF to as much as 3 kF, with operating voltages ranging from 2.5 V DC to 51.3 V DC. Moreover, these elements are characterised by a low resistance value (ESR) of 1.7 mΩ to 75 Ω and a leakage current in the range of 1 µA to 26 mA. Supercapacitors, depending on the model, are housed in various types of casings, which also differ in terms of lead spacing.

Inductors

An inductor, like a coil, is an electronic component whose function is to prevent or limit sudden changes in electrical current without power loss in AC circuits. Inductors take the form of a wire wound on a magnetic core and are used primarily in noise suppression filters or DC/DC converters. Eaton supplies surface-mounted (SMD) inductors in both standard wire-wound and common-mode versions. These components are characterised by a range of parameters such as inductance (from 22 nH to 120 mH), operating current (from 68 mA to 78 A), saturation current (from 69 mA to 123 A) and resistance (from 360 µΩ to 150 Ω).These inductors are available in a variety of housing options.

Varistors

A varistor can be described as a resistor with a non-linear, voltage-dependent resistance characteristic. In these small components, the resistance decreases as the voltage increases, so they can be used as overvoltage protection elements. When overvoltage occurs, the varistor will absorb all the energy, and thus get damaged irreversibly, so that the remaining part of the circuit can remain intact. At TME, you will find Eaton varistors designed for surface mounting (SMD). They are made in several housing variants, from the smallest 0402 to the largest 4032. The most important parameter of this type of element is its rated voltage, which in this case ranges from 16 V to 240 V.
