eldon electrical components are devices for transmitting electrical energy or signals, typically composed of several wires or groups of wires. They consist of one or more mutually insulated conductors with an outer insulating protective layer, forming wires that transmit power or information from one location to another. Typically, they are cable-like ropes formed by twisting several wires or groups of wires (each group having at least two), with mutual insulation between each group, often twisted around a central core, and the entire assembly is covered with a highly insulating sheath. Cables feature internal conductivity and external insulation.

eldon electrical component classification

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. 11. 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 the above, electromagnetic relays and reed relays are the most commonly used in electronic fabrication.

eldon electrical component applications

Dedicated solid-state relays can feature short-circuit protection, overload protection, and overheat protection. When combined with hardwired combinational logic packaging, they can realize intelligent modules required by users, suitable for direct use in control systems. Solid-state relays are widely used in computer peripheral interface equipment, temperature control systems, heating regulation, electric furnace heating control, motor control, CNC machinery, remote control systems, and industrial automation devices; signal lights, dimming, flashers, stage lighting control systems; instruments, medical devices, copiers, automatic washing machines; automatic fire fighting, security systems, and as switching switches for power capacitors for grid power factor compensation. Additionally, they are extensively used in chemical, coal mining, and other environments requiring explosion-proof, moisture-proof, and corrosion-resistant properties.

eldon electrical component applications

SMD inductors are electromagnetic induction components wound with insulated wire. They belong to commonly used inductor components. Function of SMD inductors: Passing DC and blocking AC is a simple description; they isolate AC signals, filter, or form resonant circuits with capacitors and resistors. Function of tuning and frequency selection inductors: An inductor coil connected in parallel with a capacitor can form an LC tuning circuit. Any current in the circuit through an SMD inductor generates a magnetic field, and the magnetic flux of this field acts on the circuit. When the current through the SMD inductor changes, the DC voltage potential generated in the SMD inductor opposes the change in current. When the current through the inductor coil increases, the self-induced electromotive force generated by the coil is opposite to the direction of the current, opposing the increase in current, while converting part of the electrical energy into magnetic energy stored in the inductor; when the current through the inductor coil decreases, the self-induced electromotive force is in the same direction as the current, opposing the decrease in current, while releasing stored energy to compensate for the decrease in current. Therefore, after inductive filtering, not only are the ripples in load current and voltage reduced and the waveform smoothed, but the conduction angle of the rectifier diode also increases. Inductor function 1: Color-ring inductors have a current-blocking effect: The copper core in the color-ring inductor coil always resists changes in current within the coil. Color-ring inductors impede AC current used in circuits; 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. Color-ring inductors are mainly classified into high-frequency choke coils and low-frequency choke coils. Inductor function 2: Color-ring inductors have tuning and frequency selection functions: A color-ring inductor connected in parallel with an electrolytic capacitor can form an LC tuning circuit. At resonance, the inductive reactance and capacitive reactance of the circuit are equal in magnitude but opposite in direction, meaning the natural oscillation frequency f0 of the circuit equals the frequency f of the non-AC signal, so the inductive and capacitive reactances of the loop are also equal. The usage of color-ring inductors is generally not very high, and those used in circuits are generally quite stable. Inductor function 13: The main uses of color-ring inductors include signal screening, noise filtering, current stabilization, and suppression of electromagnetic interference. The basic function of color-ring inductors is charging and discharging, but many circuit phenomena derived from this basic charge-discharge function give color-ring inductors various different applications. Today, color-ring inductors are widely used by customers, and the role played by these small inductors should not be underestimated.
