Surge Tolerant MOS Capacitors 100V Single Layer 470 pF Capacitor Chip for Aerospace Power Systems

Surge Tolerant MOS Capacitor HACC471S100V470 — 470 pF 100 V Single Layer Chip for Aerospace Power Systems

Product definition: The HACC471S100V470 is a surge-tolerant single-layer MOS capacitor with 470 pF ±10% capacitance and a 100 V DC rating. It is built on high-resistivity float-zone silicon (>1000 Ω·cm) with a 300 nm thermal SiO₂ dielectric and a TiW-Au top / TiW-Pt-Au backside metallization system, in a 0.50 × 0.50 × 0.15 mm wire-bondable chip. It is designed for aerospace, satellite, and other high-reliability power circuits that must tolerate surge and overvoltage events and also use accurate RF simulation models.
