DEOS electrical components refer to circuit boards, including: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, printed wiring boards, PCB boards, aluminum substrate boards, high-frequency boards, thick copper boards, impedance-controlled boards, PCB, ultra-thin printed wiring boards, ultra-thin circuit boards, and printed (copper etching technology) circuit boards. Circuit boards miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and optimizing appliance layouts. Circuit boards are also known as printed wiring boards or printed circuit boards. Flexible printed wiring boards and flexible circuit boards are made using polyimide or polyester film as the base material, offering high reliability and excellent flexibility. They feature high wiring density, light weight, thin profile, and good bendability.) The emergence and development of rigid-flex boards—FPC and PCB—have given rise to this new product category. Therefore, rigid-flex boards combine flexible printed wiring boards and rigid printed wiring boards through lamination and other processes according to relevant technical requirements, forming a board with both FPC and PCB characteristics.

DEOS electrical component parameters

1. Nominal varistor voltage: refers to the voltage across the varistor when a pulse current of specified duration passes through it. 2. Voltage ratio: refers to the ratio of the voltage generated by the current in the varistor to the voltage generated by another reference current in the varistor. 3. Maximum clamping voltage: refers to the peak voltage across the varistor under the maximum allowable peak pulse current Ip and specified waveform conditions. 4. Residual voltage ratio: when the current through the varistor reaches a certain value, the voltage produced across it is called the residual voltage for that current level. The residual voltage ratio is the ratio of residual voltage to nominal voltage. 5. Surge current capacity: also known as surge current rating, it refers to the maximum pulse current allowed to pass through the varistor under specified conditions. 6. Leakage current: also known as standby current, it refers to the current flowing through the varistor at specified temperature and maximum DC voltage. 7. Voltage temperature coefficient: refers to the rate of change of the varistor's nominal voltage within a specified temperature range, i.e., the relative change in voltage across the varistor when temperature changes while the current remains constant. 8. Current temperature coefficient: refers to the relative change in current flowing through the varistor when temperature changes while the voltage across it remains constant. 9. Voltage nonlinearity coefficient: refers to the ratio of static resistance to dynamic resistance of the varistor under a given applied voltage. 10. Insulation resistance: refers to the resistance between the varistor's lead wires and the insulating surface of the resistive body. 11. Static capacitance: refers to the inherent capacitive capacity of the varistor itself. 12. Rated power: the maximum power at which the varistor operates under specific ambient temperatures without causing significant variation in its varistor voltage. 20. Maximum impulse current: the maximum impulse current that causes a change in varistor voltage when applied once or twice to the varistor.

DEOS electrical component classification

Light-emitting diodes (LED) can be further classified into standard single-color LEDs, high-brightness LEDs, ultra-high-brightness LEDs, color-changing LEDs, flashing LEDs, voltage-controlled LEDs, infrared LEDs, and negative-resistance LEDs. Control modes for LED include constant current and constant voltage. There are various dimming methods, such as analog dimming and PWM dimming. Most LED applications use constant current control to maintain stable LED current, reducing susceptibility to VF variations and extending the service life of LED lighting fixtures.
