“SMT components are often not the best choice because, without special adaptations, they may not withstand the prolonged vibration stress,” said the company .” However, making electronics vibration-resistant does not necessarily require special connection techniques like press-fitting. Thanks to their enlarged solder pads and thicker base plate, the [new] capacitors can withstand acceleration up to 30g – 294m/s2.”
An extra high base is part of the adaptation, with cut-outs to improve cooling.
The capacitors have been tested “beyond the requirements of IEC 60384-4”, said the company – They must remain attached to the circuit board for four hours per axis (twelve hours total) 10Hz to 2kHz vibration with an amplitude of 0.75mm, followed by electrical tests.
Vibration resistant versions are available “on request”, said Wurth – Electronics Weekly has asked for relevant part-numbering changes.
Use is foreseen in electronically controlled tools, industrial equipment, construction machinery and drones.
