YAGEO - Driven by the infinite desire for electronic devices to be more compact and reliable, MLCCs have become one of the most developed and highly competitive capacitors segments in the market. High capacitance, low leakage currents and low resistances can only be guaranteed using wires that are free of surface defects and impurities. · Wet Tantalum capacitors are preferred where the lowest DC leakage is a required use for the circuit · Tantalum case offers the utmost reliability that withstand reverse voltage up to 3V · Can operate under higher ripple currents and can be used at temperatures up to (+200°C). Electrolytic capacitors. Figure 4-31. Capacitors do not behave the same as resistors. The common solution is to parallel tantalum capacitors for bulk capacitance and ceramic for high frequency decoupling. Kingtronics MLCC Capacitors and Tantalum Capacitors Engineers now have a choice between ceramic and tantalum when it comes to selecting capacitors with values between 0. Types of Capacitors 2.
