Tantalum capacitors are widely used in various designs. They are used as voltage-reference and spike-suppressing components, filter capacitors, and blocking and bypass capacitors in many industries, such as audio, automotive, computing and military applications. The M39003/01-5415H from Vishay Intertechnology is a hermetically sealed tantalum capacitor suitable for military, aerospace and industrial applications.

This capacitor utilizes a solid electrolyte with excellent electrical characteristics operating efficiently over a wide range of temperatures. The built-in voltage-temperature derating ensures higher current capability over a wide range of temperature. The solid, anode construction includes a manganese-dioxide cathode and a high-reliability manganese dioxide electrolyte, which provides superior performance and increased lifetime.

The M39003/01-5415H offers several applications with its wide range of internal features, such as high-volatility electrodes and a misfire detonator-type design, which helps prevent arcing, two-piece molded epoxy-sealed design, hermetically sealed construction, and capacitance range of 390 µF to 4.7 µF. This all-in-one solution is welded, sealed, laser trimmed, and with its thermal shut-off mechanism, it prevents any power runaway and fire disasters.

The M39003/01-5415H capacitor is capable of operating in temperatures as low as -55°C and as high as 125°C. It also has a maximum operating voltage of 35 Vdc, and a maximum ripple current of 5.5A. It has a height of 15mm, width of 12.5mm, and a length of 28mm. The capacitor is UL-approved, and has withstand a standard temperature rise of 130°C.

The working principle of the M39003/01-5415H capacitor is based on the charging and discharging of electrical charges. It stores an electric charge onto its plates, then discharges it when the power is switched off. When the power is switched on, it collects and stores an electrical charge from the power source. The capacitor can then charge and discharge as current passes through it, serving as a buffer to reduce voltage spikes.

In conclusion, M39003/01-5415H is an ideal capacitor for military, aerospace and industrial applications. Its one-piece design, hermetically sealed construction, and wide temperature and voltage ratings provide superior performance and longer lifetime. Thanks to its unique features, it can be used in various applications such as voltage-reference and spike-suppressing components, filter capacitors and blocking and bypass capacitors.
