We just came back from our CNY holiday,and we had a great holiday.^_^

Now we would like to take a monent to let you know our updated stock about diode M7 and LL4148 after CNY holiday.

Our Stock Notification:
LL4148 LL-34 T&R RoHS SPQ:2.5kpcs/reel 2kkpcs stock available

M7 DO-214AC T&R RoHS SPQ:5kpcs/reel    sold out

M7 is always best seller. Although we had sold out, but we will replenish it asap. If you still have request, pls feel free to contact us, and we will try our utmost to give you the quickest lead time. 

Pls kindly note there are only 2kkpcs LL4148 at present, and it will be sold out this month. Pls catch the last chance because our price is much more competitive with the stock available. 

Thank you for your kind attention and wait for your business cooperation soon. 

(1)It is recommended that capacitors should be used at a voltage less than the rated voltage.
It is also recommended to properly derate the voltage to improve operating reliability. 

(2)Customers in the product installation to avoid the occurrence of individual products locally over temperature conditions (260 ), and to avoid direct contact with high temperature soldering paste tantalum capacitor body.

(3) In low impedance circuit applications such as power supply circuits, the failure rate may increase due to inrush current.
Additionally, if a short occurs within the capacitor, burning may possibly occur.
Therefore, sufficient voltage derating is recommended. Use voltage should be within 30% -50% of the rated voltage, thereby improving the reliability of the circuit, in order to avoid the adverse effects of inrush current.

Kingtronics offers full range of Trimming Potentiometers with our own trademark "Kt" since 1990.
We gain high reputation by our trimpots superior quality and competitive price. We are proud that Kingtronics Trimpot are well-known in the overseas market.

In Jan 2016, we prepared all the key raw materials of Trimming Potentiometers and then handed over to SGS laboratory.
After 1 week testing , we got the positive reply of our potentiometers from SGS company.  Now we would like to share this good news with our Kingtronics faithful customer.
Kingtronics Trimming Potentiometer is your first chosie, and Kingtronics is your best partner.

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.
