How to maintain the continuity of orders for rigid flexible panels?
A resistor is a type of resistor that generates voltage at two applied voltages UF when current flows through it.
The basic characteristics of capacitors are as follows: (1) Static electricity, because static electricity still exists after the capacitor is powered off, the insulation of the dielectric will decrease.
The dielectric constant of the medium, which is proportional to the medium; Proportional to the dielectric; The strength of the electric field is related to frequency.
The rated voltage of a capacitor is superimposed on the medium, but cannot exceed the voltage applied to the capacitor, and the value of the rated voltage is approximately 10% of the capacitance value.
The capacity of a capacitor is related to the dielectric constant of the medium, representing the volume density of the capacitor and the dielectric constant of the medium, that is, the capacitance per unit length and the dielectric constant of the medium;
In some aspects, the capacitance parameters may change, and they are generally expressed differently, so the capacity of each type of capacitor is different;
Take the capacitance under high voltage and high current conditions, and use this data to determine the capacitance characteristics of the medium;
For temperature changes, random vibration amplitude estimation can also be used to determine the magnitude of each degree of temperature change or energy;
But this is related to capacitance, and different capacitors vary based on the temperature characteristics, operating temperature, and temperature of the dielectric material.
Capacitor materials can be divided into Y1 capacitors and X2 capacitors. For ordinary capacitors, Y capacitors are usually at "30 ° C"/"50 ° C". Different materials have different dielectric materials, such as ferrite, silica, tin oxide, and ITO glass. Y-capacitors generally use polypropylene film, NP, polystyrene film, and polyester film. At 50 ° C ± 10 ° C, the Y capacitance value under temperature characteristics is between "10 ± 2 × 50+1 × 10-6 × 50-7 × Between 50 ". Within the operating temperature range of -55 ° C ± 20 ° C and 105 ° C. Temperature characteristics of Y capacitors. 55 ° C ± 10 ° C.
The rated insulation voltage of ED is up to 50KV (V), with low input power and low input power. The input rectifier (PR) protection circuit is complex and cannot achieve high voltage isolation.
The electrical performance of ED is relatively high, with a high equivalent impedance and a high insulation resistance between adjacent conductors, which will reduce its transmission power.
