Tantalum Capacitors M39003/01-2659H Application Field and Working Principle

Tantalum capacitors are electrical components used primarily for decoupling and filtering applications within electronic circuits. The M39003/01-2659H (M39003/01) is a surface mounted, hermetically sealed, axial leaded, high capacitance, low ESR (Equivalent Series Resistance) type Tantalum capacitor with a voltage rating of 35V. Advantages of M39003/01 include: high stability, low ESR, no voltage derating and long life expectancy.

Application Field

M39003/01 is well suited for use in a broad range of applications, including: power management, automotive, communication, audio/video, and instrumentation. Its Application field is typically unrestricted where a hermetic seal is desired, and its capacitance ranges from 10uF to 470uF.Power management applications include military and civilian Aerospace, medical, lighting, and defense systems. In automotive the M39003/01 has been used successfully in airbag systems, antilock brakes, climate control, engine management, gauges, and transponder systems. In communications the capacitor is used in cell phones, fax machines, and telecom applications.Audio/video applications include high-end audio systems, broadcast systems, compact disc players, and TV sets. For instrumentation, capacitor is frequently used in DC-DC converters, handheld units, metering, and process control.

Working Principle

Tantalum capacitors have two terminals throughout, a positive and a negative.Electricity is transferred through the terminalsof the Tantalum capacitors.The capacitor is polarized, meaning that it needs to have a positive voltage on one terminal and negative voltage on the other terminal for it to work correctly.The capacitor uses Ta C as the electrolyte, which is a compound with a positive Ta ion and a negative C ion. An insulator (which is usually an oxide) is laid between these two different ions. This insulator is known as the dielectric.When a potential difference is applied across the capacitor’s terminals, the positive cation on the (+) plate is attracted to the negative voltage of the (-) plate. When the cation passes through the dielectric, electric charge accumulates on the plates thus forming the capacitance in the capacitor.Today, tantalum capacitors are the most widely used type of capacitors due to their high stability, low equivalent series resistance (ESR), and long life expectancy. M39003/01 capacitors’ hermetic seals provide additional protection from photocorrosion compared to powder-coated types, which are protected with a resin-coating on the outside. This factor helps capacitors work better in harsh environmental conditions.

Conclusion

In conclusion, the M39003/01-2659H Tantalum Capacitor is a middle voltage, high capacitance, low ESR, hermetic sealed, axial leaded component with a range of capacitance options of 10uF to 470uF. These capacitors are used primarily for decoupling and filtering applications within electronic circuits and have proven to be a reliable and durable solution for a wide range of applications. The hermetic sealed design of this tantalum capacitor has enabled it to be used in harsh environmental conditions. Their high stability, low ESR, and long life expectancy have made them the most popular choice of capacitor for many applications.
