What are Wire Wound Resistors?19 January 2026
Wire wound resistors are a type of fixed resistors. Wire-wound resistors are constructed with resistance wires wound on an insulating frame. The resistance wire is generally made of nickel-chromium, manganese-copper alloys with a certain resistivity.
What is NAND Flash?04 November 2021
NAND Flash is a better storage device than hard disk drives and is particularly evident in low-volume applications up to 4GB. As the quest continues for lower power consumption, lighter weight, and better performance, NAND is proving to be very attractive. Its development goal is to reduce the cost per bit of storage and increase storage capacity.
What is a Thyristor?11 December 2020
Thyristor, also known as silicon controlled rectifier (SCR), can control its conduction through a signal, but cannot control its turn-off, so it is called a semi-controlled device. The name thyristor often refers specifically to a basic type of thyristor, but broadly speaking, thyristors also include many derivative devices, such as Tri-Electrode AC switch (TRIAC), Fast Switching Thyristor (FST), Reverse-Conducting Thyristor (RCT) and Light-Triggered Thyristor (LTT).
What are Varactor Diodes?24 November 2025
Varactor Diodes, also known as "variable reactance diodes", are made using the characteristic that the junction capacitance varies with the applied voltage when the PN junction is reverse biased. When the reverse bias voltage increases, the junction capacitance decreases, on the contrary, the junction capacitance increases.
Introduction to BAW Filter25 September 2021
BAW filters are low-cost, small RF filters that can be utilized in a variety of applications up to 6 GHz.
What is an Electromagnetic Relay?13 October 2020
Electromagnetic relay is an electronic control device. It has a control system (also called an input loop) and a controlled system (also called an output loop). It is usually used in automatic control circuits. It actually a kind of "automatic switch" that uses a smaller current and a lower current to control a larger current and a higher voltage. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
What is a Force Sensor?19 April 2021
Force sensor (force sensor) is a component that converts the magnitude of force into related electrical signals. The force sensor can detect mechanical quantities such as tension, pressure, weight, torque, strain, and interior stress. It has become indispensable core component of power equipment, engineering machinery, various working machines, and industrial automation systems.
Battery Charger IC Guide16 February 2022
The core component of the charger is the charger IC, also known as the battery charger IC. It plays a vital role in the charging process. The battery charger IC is mainly responsible for converting AC power into DC power to match the electronic devices, so as to achieve the purpose of delivering energy to electronic devices.
DC Bias Characteristic of a Capacitor: Why MLCC Capacitance Drops Under Voltage03 July 2026
A multilayer ceramic capacitor (MLCC) marked 10 uF does not always behave like 10 uF on a live rail. Put a working DC voltage across many ceramic parts and the usable capacitance falls, sometimes dramatically. Engineers who size decoupling, bulk, and filter capacitors from the nameplate value alone can end up with a smaller reservoir, more ripple, and a filter that no longer sits where the math said it would. This guide explains the characteristic, its physics, the capacitor types it affects, how to read a derating curve, and how to design around it.
What is CPLD (Complex Programmable Logic Device)?15 October 2025
CPLD uses CMOS EPROM, EEPROM, flash memory, and SRAM programming technology, thus constituting a programmable logic device with high density, high speed, and low power consumption. They are relatively large in scale and complex in structure and belong to the range of large-scale integrated circuits.
What is VCSEL?28 October 2021
Hello everyone, I am Rose. I welcome you on board, today I will introduce VCSEL to you. The Vertical-Cavity Surface-Emitting Laser (VCSEL, or Vertical-Cavity Surface-Emitting Laser) is a semiconductor whose laser is emitted perpendicular to the top surface. It differs from an edge-fired laser, which emits the laser from the edge.
Shift Register: Classification and Working Principle26 December 2020
The shift register is a sequential logic circuit that can be used to store or transmit data in the form of binary numbers. It loads the input data and then moves or "shifts" it to its output every clock cycle, so it is called a shift register.
