UCQ1V221MCL1GS

The UCQ1V221MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UCQ series, designed for SMD assembly and optimized for audio and compact electronic applications. It delivers 220 µF at 35 V in a small 1 cm × 1 cm package and is feedable by carrier tape for automated placement.

Built for wide temperature operation (−55 °C to +105 °C) and AEC-Q200 qualification, this part combines high capacitance density, long-term endurance (2000 hours at 105 °C), and RoHS compliance for use in demanding environments.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 35 V provides bulk energy storage in a compact SMD form factor.
• Package & Mounting — Chip-type, radial can in an SMD package designed for automatic mounting machine use with carrier tape.
• Temperature Range — Operational from −55 °C to +105 °C to support designs that require wide ambient operation.
• Endurance & Reliability — Rated for 2000 hours at 105 °C; after the endurance test, capacitance change remains within ±30% and leakage current remains at or below initial specified value.
• Ripple Current Handling — Rated ripple currents of 400 mA at 120 Hz and 600 mA at 10 kHz for smoothing and filtering in power circuits.
• Leakage Current Specification — After 2 minutes at rated voltage and 20 °C, leakage current is ≤ 0.01CV or 3 µA (whichever is greater), supporting predictable bias behavior.
• Soldering Robustness — Resistance to soldering heat tested on a 250 °C hot plate for 30 seconds with capacitance change within ±10% after recovery to 20 °C.
• Compliance & Qualification — RoHS compliant and AEC-Q200 qualified, suitable for regulated and automotive-grade designs.
• Physical Footprint — Compact dimensions (L: 1.0 cm × D: 1.0 cm) with recommended land size 1.03 cm × 1.03 cm for PCB layout.
• Polarized — Polar aluminum electrolytic construction for DC smoothing and bulk capacitance applications.

Typical Applications

• Audio Equipment — Designed for SMD audio circuits where compact bulk capacitance and stable performance across temperature are required.
• Automotive Electronics — AEC-Q200 qualification and wide temperature range make it suitable for automotive electronic modules and control units.
• Power Filtering & Smoothing — Use in DC bus smoothing and decoupling where ripple currents up to 600 mA (10 kHz) are encountered.
• Compact SMD Designs — High capacitance in a 1 cm × 1 cm chip package for space-constrained boards that require automated assembly.

Unique Advantages

• High Capacitance Density: 220 µF in a 1.0 cm × 1.0 cm SMD can reduces board area for bulk storage needs.
• Automated Assembly Ready: Carrier-tape compatible chip package supports high-volume production and pick-and-place workflows.
• Wide Temperature Operation: −55 °C to +105 °C rating enables reliable operation across harsh thermal environments.
• Automotive-Grade Qualification: AEC-Q200 qualification provides a verified level of robustness for vehicle electronics.
• Predictable Endurance: 2000-hour life at 105 °C with defined limits on capacitance change and leakage for long-term design planning.
• Measurable Ripple Capability: Specified ripple current at both low and high frequencies (400 mA at 120 Hz, 600 mA at 10 kHz) for design validation.
