M39018/04-2102M

Aluminum electrolytic capacitors are widely used in a variety of electronic devices due to their high capacitance, relatively low cost, and ease of manufacture. The M39018/04-2102M is an 18mm-diameter radial leaded aluminum electrolytic capacitor. It has a maximum rated voltage of 200V and a capacitance range of 2.2µF to 22µF.

The capacitor is designed to be used in applications such as low frequency filter circuits, line-frequency filter circuits, bypass circuits, and power factor correction circuits where the required capacitance is low. The combination of a low-inductance, low-ESR design and high-ripple current rating makes it uniquely suitable for these applications.

The capacitor utilizes two layers of aluminum foil, one of which is an etched anode and the other a catalytic cathode, with an electrolytic separator in between. The separation between the two layers creates a dielectric, and current is generated when a voltage is applied. The capacitance of the M39018/04-2102M is determined by the area of the etched aluminum anode foil and the thickness of the electrolytic separator.

The M39018/04-2102M features a lower leakage current than previous aluminum electrolytic capacitors. This is because the anode and cathode layers are kept separate from each other, minimizing the contact between them and reducing the risk of short-circuiting. Leakage current is also reduced by the addition of nano-drying technology.

The M39018/04-2102M has a high temperature range of -25°C to +85°C, making it suitable for use in extreme temperature environments. The capacitor is also designed to be vibration resistant and is tested to meet applicable IEC1000-4-2, M39026/09-2105M, and JIS C5141 standards.

The M39018/04-2102M features a robust design, with an improved heat dissipation allowing it to be used in high power applications. The capacitor is designed to withstand the high currents and high temperatures associated with these applications and has a cycling life of up to 10,000 hours.

In conclusion, the M39018/04-2102M aluminum electrolytic capacitor is a reliable and cost-effective solution for a variety of power and filter applications. Its low-resistance construction, combined with its high current and temperature ratings, makes it an ideal choice for low-power systems with extreme temperature requirements.
