Electronic circuits and high-voltage circuits, LCD Backlight converter circuit.
Chip capacitors are SMD ceramic capacitors, SMD tantalum capacitors, SMD aluminum electrolytic capacitors.
Introduction to Three Types of Chip Capacitors
SMD ceramic capacitors of non-polar, the capacity is also very small (PF level), generally resistant to high temperatures and voltage, commonly used in high-frequency filtering. Ceramic capacitors look a bit like chip resistors (so sometimes we call them "chip capacitors"), but the chip capacitors do not represent the size of the number of capacity.
SMD tantalum capacitors are characterized by long life. High temperature, high accuracy, high-frequency filter to change the wave performance is excellent, but smaller capacity, the price is more expensive than aluminum capacitors, and resistance to voltage and current capacity is relatively weak. It is applied to low-frequency low-frequency filter circuit.
Chip tantalum capacitors and ceramic capacitors, the surface capacitance and pressure are marked, the surface color is usually yellow and black two. For example, 100-16 that capacity 100μF, pressure 16V.
Patch-type aluminum electrolytic capacitors have a larger capacity than the chip tantalum capacitors, which more common in the graphics card, the capacity of 300μF ~ 1500μF between the main current is to meet the low-frequency filtering and voltage regulation.
Vertical capacitance and the difference between chip capacitors
Whether it is plug-in or patch-type installation process, the capacitor itself is upright in the PCB, the fundamental difference is the way to install the chip capacitor, a black rubber base. The benefits of the chip-type production is mainly due to its high degree of automation, high precision, unlike the plug-in transport is not as easy to damage. However, the installation process requires wave soldering process, the capacitor after high temperature may affect the performance, especially the cathode with the electrolyte capacity, after high temperature electrolyte may be dry.
Features:
Multilayer ceramic capacitors are high-reliability products that have been accumulated for many years and are manufactured with reasonable technology. Small, thin, lightweight, large capacity, excellent precision inch method, automatically filled with high productivity. Residual inductance value is small, good characteristics of the number of cycles.
