UCL1C221MCL1GS

The UCL1C221MCL1GS is a chip-type, low-impedance aluminum electrolytic capacitor in a compact surface-mount can. It delivers 220 µF at a rated 16 V and is designed for automated assembly with embossed carrier taping.

Built for demanding temperature and reliability requirements, this part supports an operating range of −55 to +105 °C, AEC‑Q200 qualification, and RoHS compliance—making it suitable for automotive and other high-reliability electronics.

Key Features

• Capacitance & Voltage — Rated capacitance of 220 µF at 16 V with ±20% tolerance (120 Hz, 20 °C).
• Low Impedance — Maximum impedance of 0.16 Ω (measured at 20 °C / 100 kHz) for improved high-frequency performance.
• High Ripple Handling — Rated ripple current up to 600 mArms at 105 °C / 100 kHz and 300 mA at 120 Hz for robust power smoothing.
• Wide Temperature & Endurance — Operating temperature from −55 to +105 °C with endurance rated for 2000 hours at 105 °C.
• Compact SMD Can — Case size φ6.3 × 7.7 mm (L × D) in a surface-mount radial can package to save board space.
• Manufacturing & Compliance — Supplied in embossed carrier tape for automated mounting; RoHS compliant and AEC‑Q200 rated.
• Leakage & Loss — Specified leakage current 35.2 µA and tan δ of 0.16 (measured at 120 Hz, 20 °C).

Typical Applications

• Automotive Electronics — For in-vehicle modules where AEC‑Q200 qualification and −55 to +105 °C operation are required.
• Power Supply Filtering — Smoothing and decoupling in DC–DC converters and power rails that demand low impedance and high ripple capability.
• Surface-Mount Assemblies — Automated PCB assembly environments that use embossed carrier taping and compact SMD components.

Unique Advantages

• Low impedance at high frequency: 0.16 Ω max (20 °C / 100 kHz) supports tighter voltage regulation and reduced ripple on high-speed power rails.
• High ripple endurance: 600 mArms rating at 105 °C / 100 kHz enables reliable operation in demanding power environments.
• Wide operating temperature: −55 to +105 °C range with 2000-hour endurance at 105 °C for long-term stability under thermal stress.
• Automotive-capable qualification: AEC‑Q200 rating and RoHS compliance address industry reliability and regulatory requirements.
• PCB-space efficient: φ6.3 × 7.7 mm SMD can reduces board footprint while providing high capacitance.
• Assembly-ready packaging: Embossed carrier taping enables automated pick-and-place for high-volume manufacturing.
