UCQ1E221MCL1GS

The UCQ1E221MCL1GS is a surface-mount aluminum electrolytic capacitor designed for demanding temperature and reliability requirements. It is a chip-type SMD can from Nichicon's UCQ series, optimized for applications that require wide operating temperature, stable electrical performance, and automated placement.

Targeted use cases include automotive systems and audio equipment where AEC-Q200 qualification, wide temperature range, and long endurance are important. Key value comes from low loss (tan δ), robust ripple-handling capability, and RoHS compliance.

Key Features

• Core Type — Aluminum Electrolytic (SMD can) 220 µF capacitance at a 25 V rating in a surface-mount radial/can package suitable for automated assembly with embossed carrier taping.
• Electrical Performance Low loss tangent of 0.16 (tan δ) measured at 20°C, 120 Hz, and controlled leakage current specified at 55 µA.
• Ripple Current Capability Handles 250 mA at 120 Hz (low frequency) and 375 mA at 10 kHz (high frequency), supporting power filtering and decoupling under AC ripple conditions.
• Wide Operating Temperature Rated for −55°C to +105°C operation, enabling use across a broad thermal range.
• Endurance & Reliability 2000 hours life at 105°C and AEC-Q200 qualification for designs with elevated durability requirements.
• Assembly-Ready Packaging Surface-mount radial/can package provided on embossed carrier tape for compatibility with automatic placement equipment.
• Environmental Compliance RoHS compliant.

Typical Applications

• Automotive Electronics — Suitable for automotive subsystems where AEC-Q200 qualification and wide temperature range (−55°C to +105°C) are required.
• Audio Equipment — Chip-type SMD design and low tan δ make it appropriate for audio circuits that demand low loss and stable performance across temperature.
• Surface-Mount Production — Embossed carrier taping supports automated assembly for high-volume SMD manufacturing.

Unique Advantages

• AEC-Q200 Qualified: Provides the component-level qualification expected for higher-reliability applications.
• High Ripple Current Handling: 250 mA @120 Hz and 375 mA @10 kHz allow effective smoothing and decoupling in power circuits subject to AC ripple.
• Wide Temperature Range: −55°C to +105°C rating supports operation across harsh ambient conditions.
• Long Endurance: 2000 hours at 105°C for extended operational life in elevated-temperature systems.
• Low Loss for Signal- and Power-Sensitive Designs: tan δ of 0.16 (20°C, 120 Hz) helps maintain efficiency in audio and power applications.
• Assembly-Ready SMD Packaging: Radial can in an SMD form with embossed carrier tape enables automated placement and consistent board-level integration.
