Orga electrical components Germany Orga model Orga price

Orga electrical components refer to electronic components that generate a resonant frequency. Common types are divided into quartz crystal resonators and ceramic resonators. They function to generate frequency, featuring stability and good anti-interference performance, and are widely used in various electronic products. The frequency accuracy of quartz crystal resonators is higher than that of ceramic resonators, but the cost is also higher. Resonators mainly serve the role of frequency control; all electronic products involving frequency transmission and reception require resonators. Resonator types can be divided into through-hole and surface-mount types based on their physical form.

Orga electrical component reliability

1, Influence of environment on relay reliability: The mean time between failures is highest when the relay operates under GB and SF. 2, Influence of quality grade on relay reliability: The quality grade of the relay has a significant impact on its reliability. 3, Influence of contact form on relay reliability: The contact form of the relay also affects its reliability. The reliability of single-throw relays is higher than that of double-throw relays with the same number of poles, and reliability gradually decreases as the number of poles increases. The mean time between failures for a single-pole single-throw relay is higher than that for a four-pole double-throw relay. 4, Influence of structural type on relay reliability: There are many types of relay structures, and different types affect their reliability. 5, Influence of temperature on relay reliability: The operating temperature range of the relay is within a certain limit. As the temperature rises, the mean time between failures of the relay gradually decreases. 6, Influence of operating rate on relay reliability: As the operating rate of the relay increases, the mean time between failures basically shows an exponential downward trend. Therefore, if the designed circuit requires a very high operating rate for the relay, careful inspection of the relay is required during circuit maintenance to replace it in time. 7, Influence of current ratio on relay reliability: The so-called current ratio is the ratio of the relay's operating load current to its rated load current. The current ratio has a great impact on the reliability of the relay. Therefore, a load with a larger rated current should be selected during circuit design to reduce the current ratio, ensuring that the reliability of the relay and the entire circuit is not reduced due to fluctuations in the operating current.

Orga electrical component principles

When the voltage applied to the varistor is below its threshold, the current flowing through it is extremely small, equivalent to a resistor with infinite resistance. That is, when the voltage applied to it is below its threshold, it acts like a switch in the open state. When the voltage applied to the varistor exceeds its threshold, the current flowing through it surges, equivalent to a resistor with infinitesimal resistance. That is, when the voltage applied to it is above its threshold, it acts like a switch in the closed state. Protection principle of surge absorbers: In the standby state, the varistor has very high impedance (several megaohms) relative to the protected electronic components and does not affect the characteristics of the original design circuit. However, when an instantaneous surge voltage appears (exceeding the breakdown voltage of the surge absorber), the impedance of the surge absorber drops low (only a few ohms), causing a short circuit in the line, thereby protecting electronic products or more expensive components.

Orga electrical component parameters

Important aspects of the optical parameters of LED include: luminous flux, luminous efficacy, luminous intensity, light intensity distribution, and wavelength. 1. Luminous efficacy is the ratio of luminous flux to electrical power, with the unit generally being lm/W. Luminous efficacy represents the energy-saving characteristics of the light source, which is an important indicator for measuring the performance of modern light sources. 2.LED Luminous intensity characterizes the strength of light emission in a specific direction. Since the light intensity of LED varies significantly at different spatial angles, we have studied the light intensity distribution characteristics of LED. This parameter has great practical significance, directly affecting the minimum viewing angle of LED display devices. For example, for large color LED screens in stadiums, if the selected LED single-tube distribution range is very narrow, viewers at larger angles facing the screen will see distorted images. Moreover, traffic sign lights also require recognition by people over a wide range. 4. Regarding the spectral characteristics of LED, we mainly look at whether its monochromaticity is excellent, and pay attention to whether the main colors such as red, yellow, blue, green, and white LED are pure. Because in many occasions, such as traffic signal lights, the requirements for color are quite strict. However, observations show that some LED signal lights in China emit blue-green light for green and deep red for red. From this phenomenon, it is very necessary and meaningful to conduct specialized research on the spectral characteristics of LED.
