Hertz (Hz)
The basic unit of measurement of frequency. It is a measurement used to denote one complete occurrence of an event in one second.
The frequency of a crystal is measured in megahertz (MHz) or kilohertz (kHz). In Kingtronics we usually usd KHz.

Frequency 
Measured in Hertz (Hz), it is a periodic repetition of an event within a unit of time. 
In an electrical circuit, it is the number of times a resonator plate oscillates or vibrates in one second. The most common herts for Kingtroncis QKT is 32.768KHz

Frequency Tolerance
Often called Calibration Accuracy, it is the amount of frequency deviation from the specified nominal frequency at room temperature (25°C). 
This term is expressed as a minimum and maximum percent (%) or parts per million (ppm). Kingtronics can provide -20℃~+70℃, -40℃~+85℃, -10℃~+60℃

Load Capacitance
A capacitance, specified in picofarads (pF), presented to the crystal. 
The parallel load resonant frequency (FL) is a function of the load capacitance.

Hello dear,

Kingtronics will celebrate CNY(Chinese New Year) from 19th to 22th February, 2015.

Sorry for any inconvenience to you and pls feel free to contact us by email if you have any requests. Your email will be replied as soon as we return to work.

We would like to take this opportunity to wish you and your families all the best for a happy and healthy Chinese New Year!  O(∩_∩)O~

A good supplier should be equiped with competitive price, fine quality, quick lead time & nice packing.

Since 1990, Kingtronics owns 2 ISO factories, trimmer output is 5kkpcs/mth, faster L/T & better price than Bourns, Vishay, Murata... 

That's why we gain more and more customers from Europe, America, South Africa, Asia.

Saving cost means profit increase. All we can support is what you want. Why not move forward together~!

What is a Standard Rectifier?
A rectifier diode lets electrical current flow in only one direction and is mainly used for power supply operation. Rectifier diodes can handle higher current flow than regular diodes and are generally used in order to change alternating current into direct current. They are designed as discrete components or as integrated circuits and are usually fabricated from silicon and characterized by a fairly large P-N-junction surface. This results in high capacitance under reverse-bias conditions. In high-voltage supplies, two rectifier diodes or more may be connected in series in order to increase the peak-inverse-voltage (PIV) rating of the combination.

Types of Standard Rectifiers:
There are many different kinds of standard rectifiers, the most common types categorized by maximum reverse current, maximum peak current, maximum reverse voltage, forward voltage, packaging type and maximum average rectified current. The parametric filters on our website can help refine your search results depending on the required specifications.
The most common sizes for maximum average rectified current are 1 A, 1.5 A, 3 A, 5 A and 6 A. We also carry standard rectifiers with maximum average rectified current as high as 400 A. Forward voltage can range from 1.1 mV to 1.3 kV, with the most common standard rectifier semiconductor chips having a forward voltage of 1.1 V or 1.15 V.

Standard Rectifiers from Kingtronics:
Diode rectifier: Diode M7, LL4148, S1M, GS1M, SM4007, UF4007, 1A7, 6A10, 1N4937, 1N5343B...
Bridge rectifier:  ABS2-ABS10, DB107, MB10S, W04M, KBL410,  KBPC2510,  KBPC3510,  GBU410, GBJ810...

Applications for Standard Rectifiers:
Standard rectifiers can be found regulating the power in computers and the electrical power in motor vehicles. They can also be used in battery chargers for rechargeable batteries, computer power supplies and vehicle batteries. Also, while rectifier diodes are often used for AC to DC conversion, diodes with rectifying characteristics are found in other uses than in electronics. For example, a diode is used in the detector of radios in order to perform radio demodulation.

Usually we know crystals are referring to Quartz Crystal Resonator and Crystal Oscillator , so what is the basic difference of these two types of crystals?
Today, we would like to distinguish them from their structure. Please follow us with below blog.

Active Crystal Oscillator : Metal Lid, Quartz Blank, Coated Electrode, IC, Ceramic Base, Solder Pads.
Passive Quartz Crystal Resonator : Metal Lid, Quartz Blank, Coated Electrode, Ceramic Base, Solder Pads.

So do you find the difference ? The main point is that Crystal Oscillator is with an IC part . We are sure that you will have a better idea after you read below picture.http://www.kingtronics.com/quartz-crystals/index.html

When you order Crystal Oscillator, you have to at least keep 5 essential aspects.
Package Type,  Frequency, Suply Voltage, Frequency Tolerance,Operating Temperature

Examples : 
QKT-OSC3225, 32.768KHz,  1.8V, +/-10ppm, -10℃~+60℃
QKT-OSC5032, 32.768KHz,  3.3V, +/-20ppm, -20℃~+70℃
QKT-OSC7050, 32.768KHz,  5.0V, +/-20ppm, -40℃~+85℃

Free samples are available and welcome your enquiry and test our samples.
