40 Common sense essentials for analog circuit engineers!

1, electrical interface design, reflection attenuation is usually worse in the case of high frequency, this is because the loss of the transmission line reflection is related to the frequency, in this case, as far as possible to shorten the PCB line is extremely important. 2, the voltage regulator diode is a diode that stabilizes the working voltage of the circuit, due to the special internal structure characteristics, suitable for the working state of reverse breakdown, as long as the size of the limited ....

What are the factors that affect insulation resistance

Definition of insulation resistance Insulation resistance (IR) refers to the resistance value between two conductors of dielectric material or equipment at a specific voltage, which reflects the ability of the material to prevent the current from passing through, and is one of the core indicators to evaluate the insulation performance of electrical equipment. High insulation resistance means good insulation performance, can effectively prevent leakage, short circuit, electric shock and other safety hazards....

What does capacitance size have to do with it

A capacitor is a basic electronic component whose core property is the ability to store charge and energy in the form of electric field energy under potential difference (voltage). In the International System of Units, capacitance is measured in farads (F). # The formula for calculating capacitance size # is: Among them: CC is capacitance (unit: farad, F); QQ is the amount of charge stored on the two plates of the capacitor (unit: coulomb, C); UU is the electric potential difference (v....

How to design TVS overvoltage protection circuit quickly

The function of the overvoltage protection circuit is: if the internal voltage regulating loop of the switching power supply fails or the output voltage exceeds the design threshold due to improper operation of the user, the output voltage is limited to the safe value range in order to protect the electrical equipment of the rear stage from damage. This blog post will introduce how to quickly design overvoltage protection circuits from two methods: cost-saving TVS tube and reliable and efficient circuit ....

What is the difference between thin film capacitors and electrolytic capacitors

1, film capacitor A film capacitor is a capacitor whose core part is composed of a metal foil (as an electrode) and one or more layers of extremely thin plastic film (as a dielectric) which are alternately stacked or wound. The electrode is closely fitted with the dielectric film and maintains insulation between each other to form a large number of parallel plate capacitor units. These films can be polyester (PET, such as polyethyl ester), polypropylene (PP), polystyrene (PS), polycarbonate (PC), or other ....

Hardware design resistance: super comprehensive and detailed

1, the basic principle of resistance Resistance, together with inductors and capacitors, are the three basic passive devices in electronics. From an energy point of view, resistance is an energy-consuming component that converts electrical energy into heat energy. Usually, resistance is defined according to Ohm's law, adding a constant voltage to the resistance, how much current will be generated; Or you can use Joule's law to define how much heat is generated per unit of time when a resistor flows....

What are harmonics and stray in radio frequency

Radio frequency harmonics Harmonic concept: Harmonic refers to the signal whose frequency is an integer multiple of the fundamental frequency after the fundamental signal passes through the nonlinear element in a nonlinear circuit. In the field of radio frequency, the fundamental wave usually refers to the designed or specified operating frequency, and the harmonic is the second harmonic of the frequency, the third harmonic, etc. Harmonic causes: RF harmonics are mainly derived from nonlinear components or....
