SRAM vs DRAM: Key Differences and Applications Guide28 March 2026
Compare SRAM Chips and DRAM in 2025. Discover key differences in speed, cost, and applications to choose the best memory for your system's needs.
An Overview of LPDDR25 March 2026
LPDDR (Low Power Double Data Rate) SDRAM, a type of DDR SDRAM, also known as mDDR (Mobile DDR SDRAM), is a communication standard developed by the JEDEC Solid State Technology Association for low-power memory. Known for low power consumption and small size, it is specially used for mobile electronic products.
Clamp Diodes: Principles, Functions, and Applications23 March 2026
Clamp means jamming the position. In circuit, is means controlling the voltage. Clamp Diode is a kind of diode that is used to limit the potential of a certain point in the circuit, controlling the input voltage to a peak value to a predetermined voltage, without changing the signal. The working principlealso the unidirectional conductivity of the diode.
Working Principle and Types of Electric Fuse20 March 2026
An electric fuse is a current interrupting device that protects the electrical circuit, in which it is located by generating an open circuit in response to excessive current. This article mainly discusses the structure, working principle, materials, types, and pros and cons of electric fuse.
Resistor Symbols: From Circuit Diagrams to PCB Design20 March 2026
This comprehensive guide explores resistor symbols used in electronic circuit diagrams, covering the two main international standards: IEC (rectangle symbol) and ANSI (zig-zag symbol). The article explains how to read and interpret these symbols in schematics, distinguishing between fixed and variable resistors, and detailing specialized types like thermistors, LDRs, and varistors. It provides practical guidance for locating resistor symbols in popular EDA software (KiCad and Eagle) and includes a downloadable reference chart. The guide serves as an essential resource for electronics enthusiasts, students, and professionals who need to understand the universal language of electronic schematic symbols for circuit analysis, design, and troubleshooting.
SMD Resistors: Codes, Size, Testing, Tolerance and Selection19 March 2026
SMD Resistor or Chip Fixed Resistor is one of the metal glass glaze resistors. It is a resistor made by mixing metal powder and glass glaze powder and printing on the substrate by the screen printing method. It is resistant to humidity and high temperature and has a low-temperature coefficient. SMD Resistor can greatly save the cost of circuit space and make the design more refined.
Nickel-Cadmium Battery: Construction, Features and Working Principle19 March 2026
A nickel-cadmium battery is a system that generates DC voltage by a chemical reaction between the components. In a nickel-cadmium battery, the redox material serves as the nucleus, with a nickel sheet and a separator surrounding it. The voltage of the nickel-cadmium cell is about 1.2 V. As three or four cells are connected in sequence, the output voltage ranges from 3.6 to 4.8 V.
Introduction to Light-emitting Diode18 March 2026
The light-emitting diode is simply referred to as LED. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light.
Ohmic Resistors: Differences, Laws, and Applications18 March 2026
This article explores the fundamentals of ohmic resistors, which obey Ohm's Law and exhibit a linear voltage-current relationship. It contrasts them with non-ohmic resistors, whose resistance varies with voltage, current, or temperature. Key topics include graphical analysis, practical applications in circuits, and the impact of material choice and temperature. The article also highlights common pitfalls, real-world usage, and tips for selecting the right resistor. Understanding ohmic resistors is essential for effective circuit design, offering predictability, reliability, and simplicity across a wide range of electronic systems, from beginner projects to advanced engineering applications.
