Application No. 09/139,309
a layer of neat dielectric polymer or glass distinct from the layer of
variable voltage material and in contact with one surface of the layer of
variable voltage material,
wherein the neat dielectric polymer or glass layer is present in a
thickness of less than about 1.6 mils.
11. A variable voltage protection component for placement
between a ground plane and an electronic circuit comprising:
a first layer of variable voltage protection material comprising a
binder having dispersed therein at least about 20% by volume of
conductive or semiconductive particles;
a second layer of variable voltage protection material in contact
with the first layer comprising a binder having dispersed therein at least
40 % by volume of conductive and/or semiconductive particles; and
a third layer of variable voltage protection material in contact with
said second layer comprising a binder having dispersed therein at least
20 % by volume of conductive or semiconductive particles.
