KEMET Corporation's ALS series Aluminum electrolytic capacitors are high-performance components designed for a wide range of applications that require high reliability and long life. These capacitors have low impedance and ESR values, making them ideal for use in high-frequency applications. They also have high ripple current capability, which is important for applications that require stable voltage output. The ALS series capacitors are RoHS-compliant and lead-free, making them environmentally friendly. They are suitable for use in switch mode power supplies, LED drivers, industrial and automotive electronics, audio equipment, and telecommunications equipment.

Features

The main features of ALS series Aluminum electrolytic capacitors may be summarized as follows:

1. High Ripple Current Capability: The ALS series capacitors have a high ripple current capability, which makes them suitable for applications that require high-frequency filtering and smoothing.

2. Long Life: These capacitors are designed to have a long operational life. They use a high-purity aluminum foil with a unique etching process that reduces the formation of hot spots and prolongs the capacitor's life.

3. Low ESR: The Equivalent Series Resistance (ESR) of the ALS series capacitors is low, which means they have low power losses and are suitable for applications that require high efficiency.

4. High Capacitance: The ALS series capacitors have a high capacitance per unit volume, which means they can store a large amount of charge in a small space.

5. Low Leakage Current: The leakage current of the ALS series capacitors is low, which means they can hold their charge for a long time without significant discharge.

6. Low Impedance: These capacitors have a low impedance, which means they have a low resistance to the flow of current and can handle high surge currents.

7. Miniature Size: The ALS series capacitors are available in miniature sizes, which makes them suitable for use in small electronic devices where space is at a premium.

8. RoHS Compliant: These capacitors comply with the Restriction of Hazardous Substances (RoHS) directive, which means they do not contain any hazardous materials that can harm the environment or human health.

9. Wide Temperature Range: The ALS series capacitors are designed to operate over a wide temperature range, making them suitable for use in extreme environments.
