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。

Kt Kingtronics Stronger Support on Diodes During the International New Wave of Price Increases

Since 2018, the price hike of semiconductors has been rising from silicon wafers, passive components, MOSFETs to resistors, aluminum electrolytic capacitors, and now diodes continue to rise in price, and the price increase far exceeds expectations. In 2019, after the price surge of components last year subsided and even the price began to fall, it also ushered in a wave of diode price increases…

According to media reports, diodes price of international IDM manufacturers continued to rise in the first quarter of 2019. Manufacturers such as ON Semiconductor and Vishay are almost all rising.

In addition to the price increase of diodes, the delivery of bridge rectifiers, schottky diodes, transient voltage suppression, rectifiers, switching diodes, etc. has been extended to 16-40 weeks, the longest even 52 weeks.

At present, the demand for new energy electric vehicles and vehicle electronics in the market has risen sharply. For example, the advanced driver assistance system integrates blind spot detection, lane departure warning and parking assistance, and the number of diodes is several times higher than in the past.

It’s time to contact Kingtronics for various cost-effective solutions. Our L/T and price are even better than before, your order schedules will be easily to be fulfilled.
