Sub pF varistors are ideal for fast data rate port protection since their minimized capacitance causes little data skew. They have an ability to work in RF decks and PAs since their capacitance exhibits minimal insertion loss across a wide frequency spectrum. Their minimized capacitance makes them ideal for other capacitive sensitive applications concerned with loading on a bus or IC. Additionally, their fast response time and low leakage allow them to be used in optic circuitry and in low distortion analog circuits such as sensors and dividers.
