A large number of inductive components and EMI filter components appear in the PCB board circuit of electronic equipment. These components include chip inductors and chip magnetic beads. The following describes the characteristics of these
Magnetic beads are used to suppress high-frequency noise and spike interference on signal lines and power lines, and have the ability to absorb electrostatic pulses. Magnetic beads are used to absorb ultra-high frequency signals, such as so
The composition and selection of chip resistors Resistors are two-terminal electronic components made of resistive materials, with a certain structure, and capable of limiting the flow of current in the circuit. The resistance that cannot
The production of capacitors Capacitors are the most common product among many electronic components, and their application range is very wide. There are also many large manufacturers at home and abroad that are doing very well, such as Sa
Rated voltage of chip capacitor The rated voltage of a capacitor refers to the maximum voltage that the capacitor allows for normal operation. However, capacitors exceeding the rated voltage will not necessarily be broken down. The capacit
Schottky diode structure Schottky diodes are very different from PN junction diodes in terms of structural principles. Its interior is composed of anode metal, silicon dioxide electric field elimination material, N-epitaxial layer, N-type
The resistance of the thermistor will change with temperature, and can be divided into positive temperature coefficient (RTC) and negative temperature coefficient (NTC); the resistance of RTC increases with temperature and decreases with te
SMD thermistor 0603 10K 5% Environmental protection category: lead-free environmental protection type Main purpose: General / civil electronic information Product category: high (≤ 1%) Shape and structure features: sheet type Outgoing

For the patch transistor, some people in the industry call it a semiconductor transistor.
When selecting SMD magnetic beads, engineers should pay attention to several other points in addition to choosing the appropriate package volume.
Capacitors that can bypass high-frequency components in alternating current mixed with high-frequency currents and low-frequency currents are called "bypass capacitors."
