Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of ±20% at 120 Hz, 20°C.
• Low ESR & High Ripple Handling — ESR of 18 mΩ measured at 100 kHz supports high-frequency decoupling; ripple current ratings of 1.945 A at 120 Hz and 3.89 A at 100 kHz enable robust ripple dissipation.
• Temperature Range & Endurance — Operating temperature from −55°C to +105°C with a specified load life of 2000 hours at 105°C.
• AEC-Q200 Qualified — Qualification for automotive-grade reliability is provided (AEC-Q200), supporting use in automotive designs.
• SMD Chip Package — Surface-mount radial can (SMD) construction with part dimensions L: 1.0 cm × D: 0.8 cm and recommended land size 8.3 mm × 8.3 mm; polarized design for power-rail applications.
• Assembly & Environmental Compliance — Designed for lead-free reflow soldering (260°C peak correspondence) and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Power Electronics — Bulk and decoupling capacitor for DC‑DC converters and power modules where low ESR and high ripple current are required.
• Engine Control and ECU Power Supplies — Stable capacitance and AEC‑Q200 qualification support reliable operation across −55°C to +105°C in vehicle electronic control units.
• Infotainment and Gateway Modules — Provides high-frequency decoupling and ripple suppression for audio, communication and gateway power rails.
• Under‑hood and High‑Temperature Electronics — Load life of 2000 hours at 105°C and the specified operating range make it suitable for high-temperature automotive zones.

Unique Advantages

• Low ESR for improved transient response: 18 mΩ (100 kHz) ESR supports fast charge/discharge cycles and lowers voltage ripple on power rails.
• High ripple-current capability: Rated ripple currents at both 120 Hz and 100 kHz provide design flexibility across low- and high-frequency power stages.
• Automotive-grade qualification: AEC‑Q200 qualification and RoHS compliance address automotive reliability and environmental requirements.
• High-temperature endurance: 2000-hour load life at 105°C delivers predictable aging behavior in elevated-temperature applications.
• Surface-mount, space-conscious package: Chip SMD radial-can package with compact footprint and defined land pattern simplifies PCB integration.
• Lead-free assembly compatibility: Designed for reflow soldering up to a 260°C peak for lead-free process flows.
