xTECHNIK electrical components Germany xTECHNIK model xTECHNIK price

xTECHNIK electrical components are components that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance and only impedes changes in current. If the inductor is in a state with no current flowing through it, it will attempt to impede current flow when the circuit is connected; if the inductor is in a state with current flowing through it, it will attempt to maintain the current unchanged when the circuit is disconnected. Inductors are also known as chokes, reactors, or dynamic reactors.

Sensitivity refers to the ratio of the change in output to the change in input of a sensor under steady-state operating conditions. It is the slope of the output-input characteristic curve. If there is a linear relationship between the sensor's output and input, then the sensitivity S is a constant. Otherwise, it will vary with changes in the input. The dimension of sensitivity is the ratio of the dimensions of the output and input quantities. When the dimensions of the sensor's output and input quantities are the same, sensitivity can be understood as the amplification factor. Increasing sensitivity can yield higher measurement accuracy. However, the higher the sensitivity, the narrower the measurement range, and stability is often poorer.

1. Stable voltage refers to the stable voltage value generated across the terminals of a Zener diode when it passes the rated current. This value varies slightly with operating current and temperature. Due to differences in manufacturing processes, the stabilization voltage of Zener diodes of the same model is not completely identical. 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 dissipation is not exceeded, it is permissible, and the voltage stabilization performance will be better, but it will consume more electrical energy. 3. Dynamic resistance refers to the ratio of the change in voltage across the Zener diode to the change in current. This ratio changes with different operating currents; generally, the larger the operating current, the smaller the dynamic resistance. 4. Rated power dissipation 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, stabilization voltages below 6V belong to Zener breakdown, where 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 the 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, avalanche breakdown can only occur by increasing the reverse voltage, so the voltage temperature coefficient of avalanche breakdown is positive. For applications with high requirements for the 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. 10. Reverse leakage current refers to the leakage current generated by a Zener diode under a specified reverse voltage.

The static characteristics of a sensor refer to the relationship between the output and input of the sensor for static input signals. Since the input and output are independent of time in this case, their relationship, i.e., the static characteristics of the sensor, can be described by an algebraic equation without time variables, or by a characteristic curve plotted with the input as the abscissa and the corresponding output as the ordinate. The main parameters characterizing the static characteristics of a sensor include: linearity, sensitivity, hysteresis, repeatability, drift, etc. (1) Linearity: Refers to the degree to which the actual relationship curve between the sensor output and input deviates from the fitted straight line. It is defined as the ratio of the maximum deviation between the actual characteristic curve and the fitted straight line over the full scale range to the full-scale output value. (2) Sensitivity: Sensitivity is an important indicator of the static characteristics of a sensor. It is defined as the ratio of the increment in output to the corresponding increment in input that causes this increment. Use S to denote sensitivity. (3) Hysteresis: Hysteresis is the phenomenon where the input-output characteristic curves do not coincide during the change of input from small to large (forward stroke) and from large to small (reverse stroke). For input signals of the same magnitude, the output signals of the sensor for forward and reverse strokes are not equal; this difference is called the hysteresis difference. (4) Repeatability: Repeatability refers to the degree of inconsistency in the characteristic curves obtained when the sensor input changes continuously multiple times over the full scale in the same direction. (5) Drift: Sensor drift refers to the phenomenon where the sensor output changes over time while the input remains constant. There are two reasons for drift: one is the sensor's own structural parameters; the other is the surrounding environment (such as temperature, humidity, etc.). (6) Resolution: When the sensor input slowly increases from a non-zero value, an observable change in output occurs after exceeding a certain increment; this input increment is called the sensor's resolution, i.e., the minimum input increment. (7) Threshold: When the sensor input slowly increases from zero, an observable change in output occurs after reaching a certain value; this input value is called the sensor's threshold voltage.
