Tantalum capacitors have been the primary choice for many industrial and consumer applications for over 50 years. Alongside their various advantages compared to other types of capacitors, tantalum capacitors are reliable and cost-effective solutions for integration in long-term products and applications such as military and aerospace applications. CWR11MH105KC is a reliable and well-known type of tantalum capacitors.

CWR11MH105KC capacitor is a surface-mount, solid electrolytic type of capacitor. As part of the Kemet 11MH series, it is available in EIA case sizes ranging from 3343 (E0603) to 7343 (E1812). The capacitor operates within a voltage range of 2V to 12V, and has a capacitance range of 10uF to 22uF. Additionally, the series features low profile, long shelf life of up to 500 hours, and excellent solderability.

CWR11MH105KC capacitors’ application fields include portable communications and peripherals, automotive and industrial circuits. The device can be used as a power supply filter or a noise filter or a bypass capacitor. Additionally, it can be used as a bypass capacitor for DC-DC converters, voltage regulators and audio equipment as well as other applications including communication systems, computers and digital equipment, automotive audio and engine control systems.

CWR11MH105KC capacitors’ working principle is based on an anode made of porous sintered sintered tantalum powder that has not been fired and is filled with manganese dioxide. The anode is surrounded by a conductive solid layer of tantalum that separates the anode from the liquid electrolyte and thus forms a dielectric layer. When a voltage is applied across the capacitor, the electric field causes the liquid electrolyte to permeate the porous dielectric layer where it forms an electric double layer and stores electric energy. The chemical reaction between the electrolyte and the manganese dioxide releases oxide ions which diffuse across the oxide layer and form an insulating layer that blocks the flow of electrons and prevents reverse bias from occurring.

In summary, CWR11MH105KC is an reliable and solid type of tantalum capacitor with application fields in portable communications and peripherals, automotive and industrial circuits, used for DC-DC converters, voltage regulators, audio equipment, communication systems, computers and digital equipment, automotive audio and engine control systems. Its working principle is based on an anode made of porous sintered sintered tantalum powder filled with manganese dioxide that is surrounded by a conductive solid layer of tantalum. The electric field causes the liquid electrolyte to permeate the dielectric layer, forming an electric double layer and stores electric energy.
