sunon electrical components Germany sunon model sunon price

sunon electrical components are Zener diodes manufactured to provide voltage regulation by utilizing the reverse breakdown state of the PN junction, where the current can vary over a wide range while the voltage remains essentially constant. This diode is a semiconductor device with very high resistance up to the critical reverse breakdown voltage. At this critical breakdown point, the reverse resistance drops to a very low value; in this low-resistance region, the current increases while the voltage remains constant. Zener diodes are graded according to their breakdown voltage. Due to this characteristic, Zener diodes are primarily used as voltage regulators or voltage reference elements. Zener diodes can be connected in series for use at higher voltages, allowing higher stable voltages to be obtained through series connection.

sunon electrical component principle

A DC power supply has two electrodes: positive and negative. The positive electrode has a higher potential, and the negative electrode has a lower potential. When the two electrodes are connected to a circuit, they maintain a constant potential difference between the two ends of the circuit, thereby forming a current from the positive electrode to the negative electrode in the external circuit. Relying solely on the difference in water levels cannot maintain a steady water flow; however, using a water pump to continuously move water from a lower level to a higher level maintains a certain water level difference, forming a steady water flow. Similarly, relying solely on the electrostatic field generated by electric charges cannot maintain a steady current. By using a DC power supply, non-electrostatic forces (referred to as "non-electrostatic force") can move positive charges from the negative electrode at a lower potential back to the positive electrode at a higher potential through the interior of the power supply, maintaining the potential difference between the two electrodes and thus forming a steady current. Therefore, a DC power supply is an energy conversion device that converts other forms of energy into electrical energy to supply the circuit, maintaining the steady flow of current.

sunon electrical component structure

The main purpose of fiber optic connectors is to achieve fiber optic splicing. Fiber optic connectors, which are widely used in fiber optic communication systems, come in many types with different structures. However, upon closer examination, the basic structure of various types of fiber optic connectors is consistent: most fiber optic connectors generally use high-precision components (consisting of two ferrules and one coupling tube, making three parts in total) to achieve aligned connections of optical fibers. This method involves inserting and fixing the optical fiber into the ferrule, polishing the surface of the ferrule, and achieving alignment within the coupling tube. The outer component of the ferrule is made of metal or non-metallic materials. The mating end of the ferrule must be ground, while the other end typically uses a strain relief member to support the optical fiber or fiber optic cable to release stress. The coupling tube is generally made of two halves synthesized from materials such as ceramic or bronze, forming a tight cylindrical component, often equipped with metal or plastic flanges to facilitate the installation and fixation of the connector. To align the optical fibers as precisely as possible, the machining precision of the ferrule and coupling tube is required to be very high.

sunon electrical component function

A multimeter can not only measure the resistance of the object under test, but also AC and DC voltages, including DC voltage. Some multimeters can even measure the main parameters of transistors and the capacitance of capacitors. Fully mastering the use of a multimeter is one of the most basic skills in electronic technology. Common multimeters include analog multimeters and digital multimeters. An analog multimeter is a multifunctional measuring instrument with a meter head as its core component, and the measured value is read from the pointer of the meter head. The measured value of a digital multimeter is directly displayed in numerical form on an LCD screen, making it easy to read; some models also feature voice prompt functions. A multimeter is an instrument that integrates a voltmeter, ammeter, and ohmmeter, sharing a single meter head. The DC current range of a multimeter is a multi-range DC ammeter. Connecting shunt resistors in parallel with the meter head expands its current range. The DC voltage range of a multimeter is a multi-range DC voltmeter. Connecting voltage-divider resistors in series with the meter head expands its voltage range. Different voltage-divider resistors correspond to different ranges. The meter head of a multimeter is a magnetoelectric measuring mechanism, which can only pass DC. By using diodes to convert AC to DC, it achieves the measurement of AC electricity.
