UCZ1J221MNS1MS

The UCZ1J221MNS1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly and operation in demanding temperature environments. It delivers 220 µF at 63 V in an SMD can package tailored for automated placement from carrier tape.

Engineered for reliable performance across -40 °C to +125 °C and qualified to AEC-Q200, this part targets applications that require durable bulk capacitance, controlled ESR at low temperature, and long-term endurance at elevated temperature.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 63 V, providing substantial bulk storage for power rails and decoupling.
• High temperature range — Specified operation from -40 °C to +125 °C, supporting designs exposed to elevated ambient temperatures.
• Low-temperature ESR specification — ESR characterized after -40 °C testing with a specified ESR of 200 mΩ at 100 kHz to ensure predictable performance in cold conditions.
• Endurance & reliability — Rated for 3000 hours at 125 °C, with defined limits for capacitance change, tan δ, and leakage after endurance testing.
• Ripple handling — Supports 500 mA ripple current at 120 Hz and 1 A at 10 kHz, suitable for smoothing and filtering in switching power systems.
• Surface-mount package — Radial can SMD package (L: 1.35 × D: 1.25 cm) compatible with carrier-tape feeding for automated assembly; recommended land size L: 1.28 × W: 1.28 cm.
• Standards & compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated manufacturing requirements.

Typical Applications

• Automotive electronic modules — Bulk decoupling and power smoothing in electronic control units (ECUs) and other automotive systems where AEC-Q200 qualification and -40 °C to +125 °C operation are required.
• High-temperature power supplies — Bulk capacitance and filtering for DC–DC converters and power rails operating in elevated ambient temperatures, leveraging the 63 V rating and 3000-hour endurance at 125 °C.
• Industrial power electronics — Energy storage and ripple suppression in industrial controllers and power assemblies that demand stable ESR and ripple performance across a wide temperature range.

Unique Advantages

• Wide operating temperature range: Supports -40 °C to +125 °C operation, enabling use in temperature-challenging environments.
• AEC-Q200 qualification: Provides recognized reliability qualification for designs targeting automotive-grade applications.
• Low-temperature ESR characterization: ESR specified after -40 °C testing (200 mΩ at 100 kHz), giving engineers predictable impedance behavior in cold-start conditions.
• Long high-temperature endurance: 3000 hours at 125 °C ensures durability for sustained high-temperature operation and reduces maintenance/replacement frequency.
• Assembly-friendly SMD can: Carrier-tape compatible surface-mount package simplifies automated placement and production throughput.
• Defined ripple capacity: Specified ripple currents (500 mA at 120 Hz; 1 A at 10 kHz) let designers size the capacitor for specific switching and filtering demands.
