Knowles Precision Devices’ leaded standoff components are high-reliability parts capable of 3,000 thermal cycles with no degradation of interconnects when mounted on an FR4 board. Compared to a surface-mounted chip, lead flexibility accommodates much more board bending and flexing before internal cracks form.
 
Leaded standoffs are advantageous because they position ceramic elements off the board, ultimately providing more design flexibility. With high voltage ratings, standoffs can help control flashover across the component surface as well.
