Tantalum capacitors are used in a variety of applications, from portable electronics to electrical motors, for both commercial and military uses. The M39003/01-5346H is one of the most widely used tantalum capacitors. This capacitor consists of a tantalum anode, a dielectric layer, and a cathode. The anode material is generally made of either sintered or anodized tantalum, while the cathode is typically manganese dioxide. It is an axial-lead capacitor designed for use in resistor-capacitor(RC) circuits or for decoupling applications.

The M39003/01-5346H has a working voltage of 20V with operating temperature ranges from -55 to +85 degrees Celsius. With dimensions of 5.0 x 7.3 mm and an ESR of 10Ω it has high reliability and is suited for use in smaller electronic equipment. The device has excellent acceleration, vibration and shock resistance because of its intricate lead frame design. Maximum ratings on the M39003/01-5346H are 250 intermittent and 40 continuous watts. The device is available in either a molded or metallized body style.

The M39003/01-5346H is a non-polarized capacitor, meaning that it does not have a positive or negative polarity. Due to this, it is suitable for a variety of applications, including power supplies, decoupling circuits, and motor starting circuits. The device does not require a balancing resistor when used in series and can withstand high ripple currents due to its low ESR. It is also well-suited for use in pulse transformer and regulator circuits.

The working principle of the M39003/01-5346H is based on the electrochemical trick. When voltage is applied across its terminals, a current flows through the tantalum anode, charging it up and polarizing it. The positive and negative charges are separated by an electrolytic film, creating an electrical field that stores electrical energy. When the voltage is removed, the charge will be retained, allowing it to discharge during use.

The M39003/01-5346H offers high capacitance stability, long life, and low leakage current. Its axial lead construction allows for fast installation in tight spaces, making it an ideal choice for use in small electronic equipment. The device is RoHS compliant and can maintain its capacitance with temperature swings of up to 20°C.

In summary, the M39003/01-5346H is a popular and reliable capacitor. It is a non-polarized device, making it suitable for a variety of applications. Its axial-lead design allows for fast installation in tight spaces and its high capacitance stability, long life, and low leakage current make it an excellent choice for power supplies, decoupling circuits, and motor starting circuits.
