Robustness
of Terminations
Resistance variation within ±(0.5% + 0.05Ω)
and no mechanical damage
Tensile test: The body of the part is fixed. The tensile force was
applied gradually up to 10N. Twist test: Terminal lead was
rotated 360º of the original axis of the bent terminal,
alternating direction for 3 rotations.
