Kt Kingtronics-Stay Cool and Hydrated This Summer

An extreme heat wave is coming, how to do we can stay cool and hydrated ?

As you know, make sure you’re drinking enough water or milk.

Here sharing some ways as below, let’s stay healthy and happy during this Summer !

*Wear casual and oversized clothes. Better choose white clothing instead of black one
穿寬鬆和輕便衣服,最好選擇反光的白色衣物(黑色更吸光,適合天冷時穿)

*Wear sunscreen & hat outdoor, also sunglasses to protect your eyes
常擦防曬乳、出門攜帶帽子&到戶外戴太陽眼鏡以保護眼睛

*Take the shower with cold water
多用冷水淋浴

*Bring one towel with you, wet your towel and wipe you face and neck anytime anywhere.
隨身攜帶一條毛巾,隨時可以用冷水浸泡後擦拭臉部和頸部。

*choose a thinner blanket with air permeability 
選擇薄和透氣性好的棉被單(華人夏季有睡涼席和涼牀的傳統,有類似之處)

*try to keeping the windows open and use the fan with some breeze.
注意開窗通風以及使用風扇等

*on the other hand, close window and curtains drawn if it’s hotter outside than inside.
如白天室外陽光太強,盡量關上窗和拉上窗簾,以防室內曝曬溫度升高

*having more fruits and vegetables contain more hydrate such as watermelon and cucumber, watch out for is excessive alcohol as it can increase the risk of dehydration.
多吃西瓜、小黃瓜這類含水分較多的水果和蔬菜。盡量少喝含糖和酒精飲料。

Kt Kingtronics Updated Support on Tantalum Capacitors in July 2019

Kingtronics team is keeping making effort to improve price, lead time, service~~

Tantalum capacitors cost and lead time were big problems in the market.
After the long time effort, nowadays, glad to be informed that we manage to realize better prices and lead time for this series.

Our tantalum capacitors can cross with many other brands with more competitive prices and lead time now.
There is no reason to reject the strong support from Kingtronics, right ? 

Prices:         Surprise !!!
Lead time:    AVX           12~14 weeks
                   Vishay        11~13 weeks
                   Kingtronics  5-9 for Dipped type, 2-5 for SMD type

Kt Kingtroncs-Work Together for Preparing the Upcoming 5G Era with Increasing Demand of MLCCs

It said most popular topic in 2018 is Artificial Intelligence (AI), then the promising keyword in 2019 must be 5G mobile communication technology.

As EPCI reported:

In many respects, however, 5G will be a two-edged sword in that customer demand for new 5G mobile phones in 2019/20 is going to put additional strain on capacity within the electronic components supply network as components manufacturers and their distributors struggle to keep up with demand.

Here’s why: smartphones are the largest application market for multilayer ceramic chip capacitors (MLCCs) and at a time when major MLCC manufacturers are trying to increase production capacity to alleviating the current shortage, the dawning of the 5G era will rapidly increase the amount of MLCC s used. The average MLCC usage of 4G + (LTE-advanced) smartphones is estimated to be in the range of 550 to around 900, and it is predicted that each device in the 5G era will boost this number to more than 1,000.

We can imagine it will be a new trend and challenge to the components manufacturers and distributors for the upcoming increasing demand.

In order to have well-prepared, Kingtronics could support MLCC with Radial & SMD type with competitive lead time.

Pls feel free to share if any possible demand, we’re willing to share your burden through tough time.

Let’s work together for the prospect 5G new era ! ^@^

Kt Kingtronics Precautions for the Selection of Some Components

1. Capacitor
Chip capacitors and other components in the package of 1206 and above should be used with cautions, there is a practical risk in the welding process.
Ceramic capacitors use NPO (C0G) and X7R two types which temperature coefficient control is better. Tantalum capacitors which rated voltage is lower than 25V are preferred. The forming voltage of the Aluminum Electrolytic capacitors should be 1.2 to 1.4 times of the rated voltage.

In general, the comparison of ESR values of various capacitor: aluminum capacitor > tantalum capacitor > ceramic capacitor; 
The ripple current should not exceed the specifications under the high temperature, otherwise it will affect the service life; the limit value of each package is not recommended.

1.电容
慎用1206及以上封装的贴片电容等器件,焊接过程中有实效风险.
陶瓷电容选用NPO(C0G)和X7R这两类,温度系数控制较好。钽电解电容一般建议使用额定电压不超过25V产品。铝电解电容一般选取形成电压是额定电压的1.2到1.4倍。
一般情况下,各种电容ESR比较:铝电容>钽电容>陶瓷电容;注意高温下时的纹波电流不要超出使用规格,否则会影响使用寿命;每种封装的极限值不建议使用.


2. Diode & triode
When selecting the diode & triodes, pay attention to whether the following parameters are sufficient in the circuit to prevent the risk of damage.
Reverse breakdown voltage Vbr, reverse repeated operating voltage Vrwm, maximum average forward average current If, Instantaneous forward voltage Vf, reverse recovery time Trr, thermal resistance Rjc, maximum junction temperature Tjm.

2.二三极管
二三极管选型时注意以下参数在电路中是否够用,防止损坏风险。
反向击穿电压Vbr,反向重复工作电压Vrwm,最大平均正向平均电流If,正向压降Vf,反向恢复时间Trr,热阻Rjc,最高节温Tjm。

3. Crystals and crystal oscillators
Try to use the chip package. The largest shipment in the industry is 3.2mmx2.5mm (3225) package; 
the AT cut fundamental frequency is selected, the preferred range is 12MHz~15MHz; a crystal oscillator generally only drives one device.

3.晶体和晶振
尽量选用贴片封装,行业内目前出货量最大的是3.2mmx2.5mm(3225) 封装;
选择AT切基频,优选范围12MHz~15MHz;一个晶振一般只驱动一个器件。
