At present, because the capacitance and volume of Ta capacitor are getting larger and smaller, and it has the characteristics of low impedance, low leakage current and good high frequency characteristics, it has been applied more and more widely and its output has been rapidly increased. It is reported that the chip conversion rate of Ta capacitors on patches has developed from 71% in 1995 to over 90% at present. Its larger application area is mobile phone, accounting for about 36.2%. The average number of mobile phone applications varies from 5 to 20. The inherent performance advantages of SMT capacitors can not be replaced by other products. In some critical areas with high requirements, circuit design engineers will SMT capacitor TV. After the abolition of import tariffs on capacitors in 2003, foreign enterprises opened the door to import capacitors into China. However, according to the principle of reciprocity of preferential conditions in WTO rules, it also created conditions for China to export capacitors to other regions.
Ta capacitors on patches are suitable for power management systems with operating temperatures up to 125 C. They adopt a D shape with capacitance ranging from 10u to 100u. It is reported that this low-altitude patched tantalum capacitor uses patented technology to provide a lower [sR value] and a safer non-combustible mode. Compared with other polymer capacitors and traditional MnOZ electrode capacitors, its capacitance stability is better. Because the main raw materials used in manufacturing patch tantalum capacitors are ordinary industrial materials, the equipment used belongs to general industrial equipment, and the degree of automation is higher, so the manufacturing cost is relatively low, especially the manufacturing cost per unit capacity has overwhelming advantages over other types of capacitors.
Tantalum patch capacitors not only have excellent temperature and frequency characteristics, but also have the advantages of chip type. They have a certain growth in the application fields of low voltage and small capacity. Practice has proved that the patch tantalum capacitor has very strong vitality.
