GENERAL DESCRIPTION
AVX Radial Leaded Multi-Layer Varistors are AEC-Q200 Qualified and are designed
for durability in harsh environments or applications where leaded component is
prefered. The MLV advantage is bi-directional transient voltage protection and
EMI/RFI attenuation in the off state. This allows designers to combine the circuit
protection and EMI/RFI attenuation function into a single highly reliable device.
