jupiter electrical components Germany jupiter model jupiter price

jupiter electrical components are wires that transmit current. Usually, current transmission is point-to-point. Power cords can be divided into AC AC power cords and DC DC power cords according to their use. Usually, AC power cords are wires that carry higher voltage alternating current. Due to the high voltage, these wires require unified standards and safety certification before they can be officially produced. DC cords basically carry lower voltage direct current, so the safety requirements are not as strict as those for AC cords. However, for safety reasons, countries still require unified safety certification.

Light-emitting diodes can also be divided into ordinary monochrome LEDs, high-brightness LEDs, ultra-high-brightness LEDs, color-changing LEDs, flashing LEDs, voltage-controlled LEDs, infrared LEDs, and negative resistance LEDs. The control modes of LED include constant current and constant voltage. There are various dimming methods, such as analog dimming and PWM dimming. Most LED adopt constant current control, which can keep the LED current stable, is less affected by changes in VF, and can extend the service life of LED lamps.

jupiter electrical component composition

A diode is composed of a PN junction with corresponding electrode leads and package casing. Using different doping processes, P type semiconductor and N type semiconductor are fabricated on the same semiconductor substrate (usually silicon or germanium) through diffusion. A space charge region called the PN junction is formed at their interface. The electrode drawn from the P region is called the anode, and the electrode drawn from the N region is called the cathode. Due to the unidirectional conductivity of the PN junction, when the diode conducts, the current flows from the anode through the interior of the tube to the cathode. A diode has two electrodes: the electrode drawn from the P region is the positive pole, also called the anode; the electrode drawn from the N region is the negative pole, also called the cathode.

jupiter electrical component parameters

1. Stable voltage refers to the stable voltage value generated across the terminals when the Zener diode passes the rated current. This value changes slightly with operating current and temperature. Due to differences in manufacturing processes, the stabilization voltage of the same model of Zener diode is not completely consistent. 2. Reverse leakage current refers to the current value passing through the Zener diode when it generates a stable voltage. Below this value, although the Zener diode can still stabilize voltage, the stabilization effect will deteriorate; above this value, as long as the rated power loss is not exceeded, it is allowed, and the stabilization performance will be better, but it will consume more electrical energy. 3. Dynamic resistance refers to the ratio of the voltage change to the current change across the Zener diode. This ratio changes with the operating current; generally, the larger the operating current, the smaller the dynamic resistance. 4. Rated power consumption is determined by the allowable temperature rise of the chip, and its value is the product of the stable voltage and the maximum allowable current. 5. Temperature coefficient: If the temperature of the Zener diode changes, its stable voltage will also undergo slight changes. The relative change in voltage across the tube caused by a temperature change of 1℃ is the temperature coefficient (unit: %/℃). Generally speaking, a stabilization voltage below 6V belongs to Zener breakdown, and the temperature coefficient is negative; the temperature coefficient is positive. When the temperature rises, the depletion layer decreases. In the depletion layer, the valence electrons of atoms rise to higher energy levels, and a smaller electric field strength can excite valence electrons from atoms to produce Zener breakdown, so its temperature coefficient is negative. Avalanche breakdown occurs when the depletion layer is wider and the electric field strength is lower. An increase in temperature increases the vibration amplitude of lattice atoms, hindering the movement of carriers. In this case, only by increasing the reverse voltage can avalanche breakdown occur, so the voltage temperature coefficient of avalanche breakdown is positive. For occasions with high requirements for power supply, two Zener diodes with opposite temperature coefficients can be connected in series for compensation. Due to mutual compensation, the temperature coefficient is greatly reduced. 6. Reverse leakage current refers to the leakage current generated by the Zener diode under the specified reverse voltage.
