VISHAY 042 ASH Series High Voltage Electrolytic Capacitor, 22 µF - 250

The VISHAY 042 ASH Series comprises axial-leaded, high-voltage, standard aluminium electrolytic capacitors engineered for demanding power applications. These components deliver reliable performance for smoothing, filtering, and buffering in high-voltage circuits, making them essential for power supply units and audio-video equipment.

Crafted with a cylindrical aluminium case insulated by a distinctive blue sleeve, these capacitors are designed for durability and stable operation. They are miniaturised, offering a high capacitance-voltage (CV) product per unit volume, which is ideal for space-constrained designs on low mounting height printed circuit boards (PCBs). The construction ensures excellent resistance to vibration and shock, enhancing reliability in mobile or industrial environments.

A key feature is their proven endurance, capable of operating for up to 8000 hours at a maximum temperature of 85°C, depending on the specific case size. They are also charge and discharge proof, adding to their robustness in circuits with fluctuating loads. With an operating temperature range from -40°C to +85°C, they perform consistently in harsh conditions, from industrial machinery to portable consumer electronics.

The series offers a broad selection, with capacitance values ranging from 1µF to 220µF and working voltages from 160V DC to 450V DC, catering to a wide array of design requirements. Typical applications include industrial controls, power management systems, consumer electronics, and portable devices where consistent, high-voltage filtering is critical.
