ELTEQ electrical components, German ELTEQ models, ELTEQ prices

ELTEQ electrical components refer to electronic components that generate resonant frequencies. Common types include quartz crystal resonators and ceramic resonators. They function to generate frequencies and feature stability and good anti-interference performance, making them widely used in various electronic products. The frequency accuracy of quartz crystal resonators is higher than that of ceramic resonators, but their cost is also higher. Resonators primarily serve a frequency control function; all electronic products involving frequency transmission and reception require resonators. Based on form factor, resonators can be classified into two types: through-hole and surface-mount.

ELTEQ electrical component principles

When current flows through a conductor, the conductor heats up due to its inherent resistance. The heat generation follows this formula: Q=I2RT; where Q is the heat generated, 0.32 is a constant, I is the current flowing through the conductor, R is the resistance of the conductor, and T is the time the current flows through the conductor. From this formula, the simple working principle of a fuse becomes clear. Once the material and shape of the fuse are determined, its resistance R is relatively fixed (ignoring its temperature coefficient of resistance). When current flows through it, it generates heat, and the heat increases over time. The magnitude of the current and resistance determines the rate of heat generation, while the construction of the fuse and its installation conditions determine the rate of heat dissipation. If the rate of heat generation is less than the rate of heat dissipation, the fuse will not blow. If the rate of heat generation equals the rate of heat dissipation, it will not blow for a considerable period. If the rate of heat generation exceeds the rate of heat dissipation, heat accumulates. Due to its specific heat capacity and mass, this heat accumulation manifests as a rise in temperature. When the temperature rises above the melting point of the fuse, the fuse blows. This is the working principle of a fuse. From this principle, it is evident that when designing and manufacturing fuses, you must carefully study the physical properties of the selected materials and ensure consistent geometric dimensions, as these factors are crucial for the proper operation of the fuse. Similarly, correct installation is essential during use.

ELTEQ electrical component parameters

(1) Rated operating voltage: refers to the voltage required by the coil for the relay to operate normally. Depending on the relay model, this can be AC or DC voltage. (2) DC resistance: refers to the DC resistance of the relay coil, which can be measured with a multimeter. (3) Pull-in current: refers to the minimum current required to cause the relay to pull in. For normal operation, the applied current must be slightly greater than the pull-in current to ensure stable relay operation. The operating voltage applied to the coil should generally not exceed the rated operating voltage; otherwise, excessive current may burn out the coil. (4) Release current: refers to the maximum current at which the relay releases. When the current in the pulled-in state decreases to a certain level, the relay returns to the de-energized released state; this current is much lower than the pull-in current. (5) Contact switching voltage and current: refer to the voltage and current loads the relay is allowed to handle. These values determine the magnitude of voltage and current the relay can control. Do not exceed these values during use, as doing so can easily damage the relay contacts.
