The 0801-040-X series from Tusonix is a compact ceramic capacitor designed for high-frequency applications. With a size of 8.89 mm by 3.05 mm and a radial length of 6.35 mm, these capacitors are ideal for space-constrained PCB designs. They offer a capacitance of 0.0022 µF and a voltage rating of 500V, making them suitable for a variety of circuits that require stable decoupling or coupling capacitors.

One thing worth noting is their X5U dielectric type, which provides excellent temperature stability. Engineers tend to reach for these when they need reliable performance across a wide range of temperatures, especially in environments where thermal cycling is common. The 125°C maximum operating temperature makes them particularly useful in automotive and industrial applications where components must withstand harsh conditions.

These capacitors are commonly found in switching power supplies, filtering circuits, and RF applications. Their small footprint and robust design make them a popular choice for modern electronic devices where miniaturization is key. If you're working on projects involving high-frequency signals or needing precise decoupling in tight spaces, the 0801-040-X series from Tusonix is definitely worth considering.
