UCQ1A221MCL1GS

The UCQ1A221MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UCQ series designed for audio equipment and automotive electronics that require wide temperature operation. It is a surface-mount, polarized capacitor with a nominal capacitance of 220 µF and a rated voltage of 10 V, optimized for automated assembly (carrier tape feed) and SMD placement.

Key value propositions include wide operating temperature capability (−55 °C to +105 °C), industry-relevant qualification (AEC‑Q200), RoHS compliance, and endurance suited for demanding environments (2000 hours at 105 °C).

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a rated voltage of 10 V, with ±20% tolerance (measured at 120 Hz, 20 °C).
• Wide Temperature Range — Specified for operation from −55 °C to +105 °C, supporting designs that require extended thermal margins.
• AEC‑Q200 Qualified — Series qualification for automotive-grade applications, providing an established reliability baseline for vehicle electronics.
• Long Endurance — Rated lifetime of 2000 hours at 105 °C with defined limits on capacitance change, tan δ, and leakage current after endurance testing.
• Low-Frequency & High-Frequency Ripple Performance — Ripple current ratings of 120 mA at 120 Hz and 180 mA at 10 kHz to support filtering and decoupling in power and audio circuits.
• Leakage & Dissipation Characteristics — Leakage current specified as not more than 0.01CV or 3 µA (whichever is greater) after 2 minutes at 20 °C; tan δ max for 10 V is 0.26 (measured at 120 Hz, 20 °C).
• SMD Packaging & Assembly — Chip-type radial can SMD package designed for surface-mount placement and compatible with carrier-tape automated mounting.
• Compact Footprint — Component dimensions L: 7.7 × D: 6.3 mm with a recommended PCB land size of L: 6.6 × W: 6.6 mm for compact board designs.

Typical Applications

• Automotive Electronics — Power filtering and decoupling in vehicle systems where AEC‑Q200 qualification and wide temperature tolerance are required.
• Audio Equipment — Chip-type construction and series focus on audio use make this capacitor suitable for power supply smoothing and signal-coupling in audio modules.
• SMD Module Assemblies — Surface-mount compatibility and carrier-tape feed enable efficient automated placement in compact SMD assemblies and modules.

Unique Advantages

• Automotive-Grade Qualification: AEC‑Q200 qualification supports use in automotive designs and helps meet industry reliability expectations.
• Extended Temperature Performance: −55 °C to +105 °C rating enables use across harsh thermal environments without sacrificing electrical characteristics.
• Endurance for Demanding Duty: 2000 hours at 105 °C endurance rating provides predictable performance over extended elevated-temperature operation.
• Assembly-Friendly SMD Form Factor: Carrier-tape compatibility and SMD radial can package simplify automated manufacturing and reduce assembly costs.
• Measurable Ripple Handling: Specified ripple current values at 120 Hz and 10 kHz allow designers to size capacitors against real ripple loads in power and audio circuits.
• Clear Electrical Limits: Defined leakage current, tan δ, and impedance stability figures provide verifiable parameters for design validation and simulation.
