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。

3MM ceramic trimmer capacitor is the parts that its capacitance can be changed freely, which is mounted directly on the printed circuit board with a provision to vary its value using a small screwdriver.

Murata TZS2 series (ultra-small and thin type with external dimensions of 2.2(W) x2.7 (L) x0.95 (H) mm) have been discontinued and have not competitor sell the same product. KKT series can cross reference when users change the PCB pattern size to 3MM. KKT series are high durability from vibration, dust, moisture and flux, which is designed for reflow soldering.

Murata posted news in the website that trimmer capacitors will be discontinued after 2021 March. As a competitor, we suppose that TZR1 Series (Ultra-small and thin with external dimensions of 1.5(W)x1.7(L)x0.85(H)mm) and TZW4 Series (Compact size: 4.2(W)x5.2(L)x2.6max.(H)mm) have no replacement product in the market for the same capacitance and size.

Could you please think about using Kingtornics ceramic trimmer capacitors KKT series small size with external dimension of 3.2(W) x 4.5(L) x 1.5(T) mm? Unique construction with no plastic material provides superior soldering heat resistance to maintain excellent characteristic performance after reflow soldering. It is suitable for high frequency circuit due to high self-resonant.

A. Because the capacity of electrolytic capacitors is much larger than that of general fixed capacitors, the appropriate range should be selected for different capacities when measuring. In general, the capacitance between 1 ~ 47μF can be measured by R × 1k, and larger than 47μF can be measured by R × 100.
A、因為電解電容的容量較一般固定電容大得多,所以,測量時,應針對不同容量選用合適的量程。一般情況下,1~47μF間的電容,可用R×1k擋測量,大於47μF的電容可用R×100擋測量。

B. Connect the red meter to the negative pole and the black meter to the positive pole. At the moment of contacting, the pointer deflects to the right largely (for the same resistance, the larger the capacity, the larger the swing), and then gradually turn left until it stops at a certain point, which is  the forward leakage resistance that is slightly larger than the reverse leakage resistance. The leakage resistance should generally be above hundreds kΩ, otherwise, it will not work properly. In the test, if there is no charging phenomenon in the forward direction and the reverse direction, that is the needle does not move, which means that the capacity disappears or the internal circuit is broken. If the resistance measured is small or zero, it indicates that the capacitor is large leakage resistance or has been broken and damaged, cannot be use any more.
B、將萬用表紅表筆接負極,黑表筆接正極,在剛接觸的瞬間,萬用表指針即向右偏轉較大偏度(對於同一電阻擋,容量越大,擺幅越大),接着逐漸向左迴轉,直到停在某一位置。此時的阻值便是電解電容的正向漏電阻,此值略大於反向漏電阻。電解電容的漏電阻一般應在幾百kΩ以上,否則,將不能正常工作。在測試中,若正向、反向均無充電的現象,即錶針不動,則說明容量消失或內部斷路;如果所測阻值很小或為零,說明電容漏電大或已擊穿損壞,不能再使用。

C. For the electrolytic capacitor whose signs are unknown, it can be discriminated by using the above method. Frist, measure the leakage resistance at randomly and remember its swing. Then, exchange the test leads to measure a resistance. In two measurements, the large resistance is the forward connection, that is the black meter is connected to the positive pole and the red one is connected to the negative pole.
C、對於正、負極標誌不明的電解電容器,可利用上述測量漏電阻的方法加以判別。即先任意測一下漏電阻,記住其大小,然後交換表筆再測出一個阻值。兩次測量中阻值大的那一次便是正向接法,即黑表筆接的是正極,紅表筆接的是負極。

D. Via the multimeter to charge the electrolytic capacitor from the positive and the reverse side, the capacity can be estimated according to the magnitude of the swinging.
D、使用萬用表電阻擋,採用給電解電容進行正、反向充電的方法,根據指針向右擺動幅度的大小,可估測出電解電容的容量。
