The HACC331S50V150 is a single layer MOS (metal-oxide-semiconductor) capacitor that uses a thermally grown silicon dioxide (SiO2) dielectric on a float-zone silicon substrate. Its self-healing dielectric design isolates a localized breakdown site so that a transient overvoltage does not develop into a permanent short circuit. It is a wire-bondable RF capacitor rated 330 pF ±10% at 50 V DC in a 0.50 × 0.50 × 0.15 mm chip, and it is also known as a single layer ceramic capacitor (SLC) or wire bondable capacitor.
