In January 2015, in order to meet customers demands, we prepared new Quartz Crystals and Oscillators samples to SGS lab.
After two weeks, we get the updated new RoHS 2.0 Test Report .

Below is the full list of our Kingtronics RoHS report, please have a quick view.

Active Electronics Components
1. UL certification for bridge rectifiers
2. RoHS 2.0 for diode rectifier, and specially Reach 2.0 for diode M7 ( also called SMD 1N4007)

Passive Electronics Components
1, CKT---Chip Tantalum Capacitors RoHS 2.0 certificated
2, TKT---Dipped Tantalum Capacitors RoHS 2.0 certificated
3, QKT--- Quartz Crystals and Oscillators RoHS 2.0 certification 
4, MKT, AKT --- Monolithic ceramic capacitors/Axial Monolithic Ceramic capacitors/ Axial Color Ring Capacitors/ SMD Multilayer Ceramic capacitors/ Ceramic Capacitors

Above products are tested not including 155 substances of very high concern(SVHC) under Regulation(EC) No 1907/2006 of Reach.

Kingtronics products are all with RoHS certifications. Please feel free to contact with us and test our samples.

Tantalum Capacitors enjoy low leakage current characteristics; Better filtering let the leakage current extremely low.

Nearly no failure mode to tantalum capacitors, as they have self-healing capability, life time is more stable compared with Aluminum electrolytic, which only has 1000-2000Hours.

Kingtronics produce and sell Radial and Chip Tantalum Capacitors, Please refer to the following table and link : www.kingtronics.com/tantalum-capacitors/

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~!
