The capacitors E
LV1
and E
LV2
are implemented as SMD tantalum capacitors in order to achieve the respective
capacity values required.
The capacitors C
LV1
and C
LV2
are implemented as SMD ceramic capacitors; thereby, a connection with
extremely low impedance is achieved.
The capacitor C
X
is situated directly at the LV power connector. Since, in the case of a defect of these filter
capacitors (e.g. short-circuit caused by a breakage of the component), the LV fuse does not provide any
protection for the device, special and extremely reliable types are used which offer a very high degree of
robustness with respect to mechanical forces.
