What is Time Delay Relay?18 December 2025
Hello everyone, I am Rose. Today I will introduce Time Relay to you. A Time Relay is an electrical component that is used on a circuit with a lower voltage or lower current to turn on or off a circuit with a higher voltage and bigger current or to regulate a higher voltage or larger power. This article will introduce some basic knowledge of Time Relay.

Power Management Integrated Circuit (PMIC) Guide10 February 2022
Power Management Integrated Circuits (PMIC) is a chip that is responsible for the conversion, distribution, detection and other power management of electrical energy in electronic equipment systems.
An Overview of Crystal Oscillator21 September 2020
The oscillator is an energy conversion device that converts DC power into AC power with a certain frequency, and the circuit formed by it is called an oscillating circuit. Some electronic devices require an AC signal with a highly stable frequency, but the LC oscillator has poor stability and the frequency is easy to drift. A special component-quartz crystal is used in the oscillator, which can generate a highly stable signal. This kind of oscillator using a quartz crystal is called a crystal oscillator.
Near Field Communication (NFC) Explained: Working and Applications24 May 2021
Near Field Communication (NFC) is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. Devices using NFC technology can exchange data when they are close to each other. By integrating the functions of inductive card readers, inductive cards, and point-to-point communication on a single chip, applications such as mobile payment, e-ticketing, access control, mobile identification, and anti-counterfeiting can be realized by using mobile terminals.
Introduction to Centrifugal Switch27 January 2021
On the theory of centrifugal power, a centrifugal switch operates. It's just an electric switch. These switches are specially designed for induction motors in single and split phases. As its operation is identical to that of a centrifugal clutch used in vehicles, the centrifugal switch is generally known as 'clutch'.
Introduction to TVS Diodes07 August 2020
TVS diodes (Transient voltage suppression diodes), also called clamp diodes, are electronic parts for protection, which can protect electrical equipment from voltage spikes introduced by wires. It is a high-performance circuit protection device commonly used internationally.
Graphics Card Explained: Classification, Working and Structure27 May 2021
A Graphics card (Video card, Display card, Video adapter) is one of the basic components of personal computers. It converts the display information required by the computer system to drive the display, which is an important component that connects the monitor and the PC motherboard, and is one of the important equipment of "human-machine". Its built-in parallel computing capability is also used for deep learning and other operations.
