PERFORMANCE CHARACTERISTICS
FEEDTHRU VARISTORS
AVX Multilayer Feedthru Varistors (MLVF) are an ideal choice
for system designers with transient strike and broadband
EMI/RFI concerns.
Feedthru Varistors utilize a ZnO varistor material and the
electrode pattern of a feedthru capacitor. This combination
allows the package advantage of the feedthru and material
advantages of the ZnO dielectric to be optimized.
ZnO MLV Feedthrus exhibit electrical and physical advantages
over standard ZnO MLVs. Among them are:
1. Faster Turn on Time
2. Broadband EMI attenuation
3. Small size (relative to discrete MLV and EMI filter schemes)
Discrete MLV Model
The electrical model for a ZnO MLV and a ZnO Feedthru MLV
are shown below. The key difference in the model for
the Feedthru is a transformation in parallel to series induc-
tance. The added series inductance helps lower the injected
transient peak current (by 2πfL) resulting in an additional ben-
efit of a lower clamping voltage. The lowered parallel induc-
tance decreases the turn on time for the varistor to <250ps.
