Polarion electrical components Germany Polarion model Polarion price

Polarion electrical components consist of two conductors placed close to each other with a non-conductive insulating dielectric layer in between, forming a capacitor. When voltage is applied across the two plates of the capacitor, it stores charge. The capacitance value is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of capacitance is the Farad (F). In circuit diagrams, the letter C is commonly used to represent capacitive elements; capacitors are components that store electric charge and electrical energy (electric potential energy). A system of conductors where one conductor is surrounded by another, or where all electric field lines originating from one conductor terminate on another conductor, is called a capacitor.

A multimeter mainly consists of three parts: the meter head, the measurement circuit, and the selector switch. The multimeter is the most basic tool in the field of electronic testing and is also a widely used test instrument. Multimeters are also known as multi-meters, triple-meters (A, V, Ω, i.e., for current, voltage, and resistance), multiplex meters, or universal meters. Multimeters are divided into analog multimeters and digital multimeters. There is also an oscilloscope multimeter with oscilloscope functions, which is a multifunctional, multi-range measuring instrument. General multimeters can measure DC current, DC voltage, AC voltage, resistance, and audio levels. Some can also measure AC current, capacitance, inductance, temperature, and certain parameters of semiconductors (diodes, transistors). Digital multimeters have become mainstream and have replaced analog instruments. Compared with analog instruments, digital instruments offer higher sensitivity, higher accuracy, clearer display, stronger overload capacity, and are easier to carry and simpler to use.

Sensors generally consist of four parts: sensitive elements, conversion elements, signal conditioning circuits, and auxiliary power supplies. Sensitive elements directly sense the measured quantity and output physical signals with a definite relationship to the measured quantity; conversion elements convert the physical signals output by the sensitive elements into electrical signals; signal conditioning circuits are responsible for amplifying and modulating the electrical signals output by the conversion elements; conversion elements and signal conditioning circuits generally require power supply from auxiliary power sources.

Polarion electrical component structure

Inductors generally consist of a bobbin, winding, shield, encapsulation material, magnetic core, or iron core. 1. Bobbin: The bobbin refers to the support for winding the coil. For some larger fixed inductors or adjustable inductors (such as oscillator coils and choke coils), enameled wire (or silk-covered wire) is mostly wound around the bobbin, and then a magnetic core, copper core, or iron core is inserted into the inner cavity of the bobbin to increase its inductance. Bobbins are usually made of plastic, bakelite, or ceramic, and can be manufactured into different shapes according to actual needs. Small inductors (such as color-coded inductors) generally do not use bobbins; instead, the enameled wire is wound directly onto the magnetic core. Air-core inductors (also known as former-less coils or air-core coils, mostly used in high-frequency circuits) do not use magnetic cores, bobbins, or shields. Instead, they are wound on a mold first, then the mold is removed, and a certain distance is maintained between the turns of the coil. 2. Winding: The winding refers to a set of coils with specified functions, and it is the basic component of an inductor. Windings are classified into single-layer and multi-layer types. Single-layer windings come in two forms: close-wound (where wires are wound turn by turn adjacent to each other) and spaced-wound (where a certain distance is kept between each turn during winding); multi-layer windings include layered flat winding, random winding, honeycomb winding, and other methods. 3. Magnetic Core and Magnetic Rod: Magnetic cores and magnetic rods are generally made of materials such as nickel-zinc ferrite or manganese-zinc ferrite. They come in various shapes such as "I" shape, cylindrical, cap-shaped, "E" shape, and pot core shape. 4. Iron Core: The main materials for iron cores are silicon steel sheets and permalloy, and their external shape is mostly "E" type. 5. Shield: To prevent the magnetic field generated by some inductors during operation from affecting the normal operation of other circuits and components, a metal shield is added (such as the oscillator coils in semiconductor radios). Using a shield increases the loss of the coil, reducing the Q value. 11. Encapsulation Material: Some inductors (such as color-coded inductors and color-ring inductors) are sealed with encapsulation material after winding, covering the coil and magnetic core. The encapsulation material is typically plastic or epoxy resin.
