TEST CONDITIONS
TEST METHOD
Filter is soldered onto the center of PCB which is laid on two small supporters
spaced 90mm apart. The PCB is deflected to 1mm below the horizontal level by the
pressing stick for 1 second and repeated 5 times.
A force of 1.0 Kg shall be applied to each terminal in the direction of the axis of
terminal for 30 ± 5 seconds.
A force of 250 gf is applied to each lead in axial direction. The lead shall be bent
90 degrees to one direction, then in opposite direction and returned to the
original position.
Lead terminals are immersed in methanol with 7 to 10% of rosin flux for about
5 seconds, then immersed in soldering bath at 230 ± 5°C for 5 ± 0.5 seconds.
Drop 3 times on concrete floor from 1.0 meter, (30cm for some products).
Vibration amplitude of 1.5mm at 10-55Hz in each of three mutually
perpendicular directions for 1 hour.
