A range of anti-vibration aluminium electrolytic capacitors from Panasonic are now being shipped by Farnell. The components are suitable for use in DC/DC Converters and AC/DC converters in a wide variety of transportation and harsh-environment applications such as industrial, power supply and robotics, due to their small size, reliability and strong, dependable soldering connectability.

The growing demand for eco-friendly cars, energy efficiency and the need to comply with environmental regulation has led to greater numbers of ECUs being employed within car design.

Alongside this, demand for high-precision control, a higher degree of freedom in component layout and reduction in number of cables has also led to the adoption of an integrated configuration of mechanical and electrical in-vehicle components, with ECUs positioned in the engine rather than the engineer compartment.

This trend has created the need for ECUs in a smaller size, combined with better resistance to vibration.

The anti-vibration capacitors are AEC-Q200 compliant for automotive applications and are smaller than traditional capacitors from just 6.3mm in diameter, whilst withstanding vibration acceleration of 30G.

Adoption of Panasonic’s anti-vibration capacitors removes the need for anti-vibration reinforcement as part of the board mounting process, allowing customers to streamline their production processes.

Also, auxiliary terminals on the 6.3mm capacitor are positioned on the sides of the capacitor to ease visual confirmation of auxiliary terminal soldering, ensure stable soldering properties, and enhance the ECUs overall vibration resistance.

Key features/benefits include anti-vibration withstanding up to 30Gs and surface mount Technology.

They are available in 6.3mm to 18mm diameters and are AEC-Q200 compliant and RoHS and REACH compliant.
