Leaded transient voltage/RFI suppressors (SHCVs)
SHCV series
Features
RFI noise suppression and transient overvoltage protection integrated in a
single component
Reliable protection against automotive transients such as load dump and
jump start (for SR1 and SR2 types)
High capacitance (up to 4.7 μF)
Low clamping voltage
RoHS-compatible
Suitable for lead-free soldering
PSpice simulation models available
Applications
RFI noise suppression and transient overvoltage protection on DC lines of
small motors, windscreen wipers, window lifters, mirrors, central locking,
memory seat, sunroof
Design
Combination of multilayer RF filter capacitor and multilayer varistor
Coating: flame-retardant to UL 94 V0, epoxy resin
Terminals: tinned iron wire, RoHS-compatible
V/I characteristics and derating curves
V/I and derating curves are attached to the data sheet. The curves are sorted
by V RMS and then by case size, which is included in the type designation.
