Dear purchsers and sales,
 
How is your work going recently?
 
From this year, Kingtronics products have a great improvement on price and delivery. Take zener diode as an example, we adjust its price, and some are even lower than before.
 
Because it has a large consumption on manufacturing such as protector and heat controller, I believe you will benefit a lot from our price down.

Kt Kingtronics 1N4148

14 Oct 2011

1N4148 Description:

The 1N4148 is a small signal, high-speed switching diode.

Typically found in a DO-35 glass axial package it is very useful at high frequencies and are very popular in low-current applications.

Currently the 1N4148 is sourced by manufacturers.It is also known as the 1N914.

1N4148 Features

VRRM = 100V (Maximum Repetitive Reverse Voltage)

IO = 200mA (Average Rectified Forward Current)

IF = 300mA (DC Forward Current)

IFSM = 1.0 A (Pulse Width = 1 sec), 4.0 A (Pulse Width = 1 uSec) (Non-Repetitive Peak Forward Surge Current)

PD = 500 mW (power Dissipation)

TRR < 4ns (reverse recovery time)

Device Category:Diodes and Rectifiers

1N4148 Applications:High-speed switching

Kt Kingtronics Diodes

25 Jul 2011

There are a number of different electronic devices which tend to be called diodes.

Although they're made differently they all have three things in common.

They have two leads like a resistor.
The current they pass depends upon the voltage between the leads.
They do not obey Ohm's law!

As an example we will use a typical diode called a pn-junction. This allows us to explain behaviour of diodes.

The function of a diode is to allow current in one direction and to block current in the opposite direction.

The terminals of a diode are called the anode and cathode. There are two kinds of semiconductor diodes: a P-N junction diode, which forms an electrical barrier at the interface between N- and P-type semiconductor layers, and a Schottky diode, whose barrier is formed between metal and semiconductor regions.

Remember, however, that there are other sorts of diodes which are built differently but show the same general behaviour.

About

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
