Typical Performance
Limiting voltage
When choosing a surge protection device it is
important to determine the limiting voltage for a
given surge level. Figure 1 shows the effectiveness
of the CA350 series for a 6kV overvoltage. The lim-
iting voltage shows the level of surge ‘let-through’
the surge protection device - in this case just over
600V for a fraction of a microsecond and repre-
sents a very small amount of energy.
Attenuation characteristics
The inclusion of a surge protection device should
have minimal effect on a system other than to
safeguard vulnerable equipment. The attenuation
plot shown in fi gure 2 emphasises how little the
system is changed after fi tting a CA series SPD.
Return Loss
Figure 3 shows the return loss for the N-type vari-
ant of the CA series.
Equivalent circuit
An equivalent circuit model of the CAxx/N is il-
lustrated in fi gure 4. This model gives reasonable
agreement with measured frequency response to
4.2GHz and return loss to 2.5GHz.
