UCZ1A221MCS1GS

The UCZ1A221MCS1GS is a high-reliability, chip-type aluminum electrolytic capacitor designed for surface-mount assembly. With a 220 µF capacitance at 10 V, low-temperature ESR specification and defined ripple current ratings, it targets power-decoupling and smoothing roles in applications that demand stable performance across a wide temperature range.

Engineered for sustained operation from -40°C to +125°C and qualified to AEC-Q200, this capacitor delivers predictable endurance (3000 hours at 125°C for its case size) and is supplied in embossed carrier taping for automated pick-and-place assembly.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with ±20% tolerance, rated for 10 V operation.
• Low-temperature ESR specification — ESR characterized at -40°C and specified ESR of 200 mΩ at 20°C/100 kHz for predictable high-frequency behavior.
• Ripple current capability — Low-frequency ripple current 135 mA (120 Hz) and high-frequency ripple current 270 mA (10 kHz) to support power-rail smoothing and transient energy delivery.
• Leakage current — Specified leakage current of 22 µA for controlled standby losses and predictable bias behavior.
• High-temperature endurance & temperature range — Rated for continuous operation from -40°C to +125°C with an endurance rating of 3000 hours at 125°C for the φ8 case size.
• Reliability & qualification — AEC-Q200 qualified and designed as a high-reliability chip type for demanding electronic systems.
• Surface-mount package — Chip-style radial can SMD (φ8 × 10L), vibration resistant and delivered in embossed carrier taping for automated assembly.
• RoHS compliant — Meets RoHS directive requirements.

Typical Applications

• Automotive power electronics — Bulk smoothing and decoupling for automotive ECUs and power modules where AEC-Q200 qualification and high-temperature endurance matter.
• DC–DC converter output filtering — Supports output rails with defined ESR and ripple current handling to stabilize voltage under dynamic load.
• Industrial control electronics — High-temperature capability and vibration resistance make it suitable for controllers and power stages operating in harsh environments.
• High-reliability embedded systems — Use where long endurance at elevated temperature and predictable leakage and ESR characteristics are required.

Unique Advantages

• Defined low-temperature ESR — ESR specified after -40°C testing ensures more predictable performance across the full operating temperature range.
• High-temperature endurance — 3000 hours at 125°C (for the φ8 case size) provides long-term stability in thermally demanding applications.
• Measured ripple performance — Separate low- and high-frequency ripple current ratings (135 mA @120 Hz, 270 mA @10 kHz) let designers match component selection to actual power-system conditions.
• Compact SMD form factor — φ8 × 10L chip-style can combines compact footprint with vibration resistance for reliable automated assembly and robust in-field operation.
• AEC-Q200 qualified — Provides an established reliability baseline for applications requiring supplier-backed qualification data.
• Embossed carrier tape packaging — Streamlines high-volume surface-mount production with compatibility for automatic mounting machines.
