elcom electrical components German elcom models elcom prices

elcom electrical components are accessory products used to achieve electrical connections, categorized industrially as connectors. As the level of industrial automation increases and industrial control requirements become stricter and more precise, the usage of terminal blocks is gradually rising. With the development of the electronics industry, the scope of application for terminal blocks is expanding, and their varieties are increasing. Besides PCB board terminals, the most widely used types include hardware terminals, nut terminals, spring terminals, and so on.

Function of elcom electrical components

The self-induced electromotive force in an inductor coil always opposes the change in current within the coil. Inductor coils impede alternating current; the magnitude of this impedance is called inductive reactance xl, measured in ohms. Its relationship with inductance l and AC frequency f is xl=2πfl. Inductors are mainly classified into high-frequency choke coils and low-frequency choke coils. An inductor coil connected in parallel with a capacitor can form an lc tuned circuit. When the natural oscillation frequency f0 of the circuit equals the frequency f of the AC signal, the inductive reactance equals the capacitive reactance, causing electromagnetic energy to oscillate between the inductor and the capacitor; this is the resonance phenomenon of the lc circuit. At resonance, the inductive and capacitive reactances are equal in magnitude but opposite in direction, resulting in minimum total impedance and maximum current in the circuit (for an AC signal where f="f10"). The lc resonant circuit has frequency selection capability, allowing it to select AC signals of a specific frequency f.

Structure of elcom electrical components

1. Electrodes: The electrodes of a fuel cell are the sites for electrochemical reactions where fuel undergoes oxidation and oxidant undergoes reduction. Their performance depends critically on catalyst performance, electrode materials, and electrode manufacturing processes. 2. Electrolyte membrane: Its main function is to separate the oxidant from the reductant and conduct ions. 8. Current collector: Also known as a bipolar plate, it functions to collect current, separate oxidant from reductant, and guide reaction gases. The performance of the current collector mainly depends on its material properties, flow field design, and processing technology.

Classification of elcom electrical components

1. Classification by relay physical dimensions: (1) miniature relays, (2) sub-miniature relays, (3) small miniature relays. 2. Classification by relay load: (1) micro-power relays, (2) low-power relays, (3) medium-power relays, (4) high-power relays. 13. Classification by relay protection characteristics: (1) Sealed relays: Relays where contacts and coils are sealed inside a cover using welding or other methods, isolating them from the surrounding medium, resulting in a low leakage rate. (2) Enclosed relays: Relays where contacts and coils are protected by a housing (non-sealed). (3) Open relays: Relays that do not use a protective cover for contacts and coils. Among these, electromagnetic relays and reed relays are the most commonly used in electronic fabrication.
