Key value propositions include low impedance, a wide operating temperature range, and a 2,000-hour endurance at 105°C.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a rated voltage of 6.3 V with ±20% tolerance (120 Hz, 20°C).
• Low-Impedance Chip Type — Chip-type, low-impedance construction suited for board-level bulk decoupling and power-supply smoothing; specified impedance 260 mΩ.
• Loss Characteristics — Tan δ (DF) max 0.26 measured at 120 Hz, 20°C, giving predictable ESR-related losses for power calculations.
• Ripple Current Capability — Rated low-frequency ripple current 150 mA at 120 Hz and high-frequency ripple current 300 mA at 10 kHz for handling AC components on DC rails.
• Leakage Current — Specified leakage current of 13.86 µA after standard conditioning, useful for low-leakage applications.
• Temperature & Endurance — Operating range −55°C to +105°C with endurance specified as 2,000 hours at 105°C.
• Package & Mounting — Surface-mount radial can (chip) package, package size φ6.3 × 5.8 mm, surface-mount land size 6.6 × 6.6 mm; supplied in embossed carrier taping for automated placement.
• Compliance & Ratings — AEC-Q200 rating and RoHS compliance noted in product data.

Typical Applications

• Automotive Electronic Modules — Bulk decoupling and smoothing on 6.3 V rails in automotive control modules where AEC-Q200 qualification and a wide temperature range are required.
• Power Supply Filtering — Board-level smoothing and transient absorption for DC–DC converter outputs and low-voltage power rails, leveraging the part's low impedance and ripple-handling specs.
• Industrial Control Equipment — Energy storage and decoupling in industrial controllers and instrumentation operating across −55°C to +105°C with long endurance at elevated temperature.
• Embedded Systems — Local bulk capacitance for microcontroller and peripheral power domains on compact SMD layouts where a φ6.3 × 5.8 mm footprint is advantageous.

Unique Advantages

• Compact bulk capacitance: 220 µF in a φ6.3 × 5.8 mm SMD can provides substantial capacitance without large board area.
• Predictable power performance: Specified impedance (260 mΩ), tan δ and ripple currents enable accurate thermal and power-rail budgeting.
• High-temperature endurance: 2,000 hours at 105°C supports reliable operation in elevated-temperature applications and long-term stability requirements.
• Automotive-capable: AEC-Q200 rating allows use in automotive electronic modules that require industry-recognized component qualification.
• Production-ready packaging: Supplied in embossed carrier taping for automated pick-and-place and high-volume assembly flows.
• Wide operating range: −55°C to +105°C supports deployment across harsh thermal environments common in industrial and automotive sectors.
