UCD1V221MCL6GS

The UCD1V221MCL6GS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly on high-density PCBs. It delivers 220 µF capacitance at a 35 V rating with engineered low impedance and controlled dissipation for demanding power-decoupling roles.

Built for robust operation from −55°C to 105°C and qualified to AEC-Q200, this SMD capacitor targets automotive and industrial power applications that require automated placement and consistent endurance performance.

Key Features

• Electrical Performance — 220 µF nominal capacitance with a tolerance of −20% to +20%, rated at 35 V and specified tanδ of 0.12 (measured at 20°C, 120 Hz).
• Low Impedance & Ripple Handling — Specified impedance of 180 mΩ and ripple current ratings of 300 mA at 120 Hz and 600 mA at 10 kHz, enabling effective smoothing and decoupling in power rails.
• Leakage Current — Rated leakage current of 77 µA, supporting predictable standby and bias behavior in system designs.
• Thermal & Endurance — Operating temperature range −55°C to 105°C with a rated endurance of 2000 hours at 105°C.
• Package & Assembly — φ10 × 7.7 mm chip-type can in an SMD format, supplied in embossed carrier taping for automatic placement; package case listed as Radial, Can - SMD.
• Qualification & Compliance — AEC-Q200 rated and RoHS compliant, supporting regulated and reliability-focused applications.

Typical Applications

• Automotive Power Electronics — Bulk decoupling and smoothing on DC–DC converter inputs and outputs where AEC-Q200 qualification and high-temperature endurance are required.
• Engine Control & ECU Modules — Local energy storage and ripple suppression on control and sensing power rails operating across wide temperature ranges.
• Industrial Embedded Systems — Power rail stabilization in compact, high-density PCBs that use automated surface-mount assembly.

Unique Advantages

• Compact SMD Can — φ10 × 7.7 mm form factor reduces board footprint while providing substantial capacitance for power filtering.
• Low-Impedance Design — 180 mΩ impedance and specified ripple currents (300 mA @120 Hz, 600 mA @10 kHz) improve transient response and reduce voltage ripple on supply rails.
• Automated Assembly Ready — Supplied in embossed carrier taping for reliable, high-throughput placement by automatic mounting equipment.
• High-Temperature Endurance — Rated for 2000 hours at 105°C, enabling durable operation in thermally demanding environments.
• Standards Compliance — AEC-Q200 rating and RoHS compliance provide verifiable qualification and regulatory alignment for automotive and industrial use.
