UCD1E221MCL6GS

The UCD1E221MCL6GS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UCD series, designed as a low-impedance chip-type capacitor for high-density PCBs. With a rated capacitance of 220 µF at 25 V and an operating temperature range from −55 °C to 105 °C, it targets applications where compact, reliable power filtering and decoupling are required, including automotive electronic modules.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a 25 V rated voltage with a capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Low Impedance Performance — Specified impedance of 180 mΩ and a tangent of loss angle (tan δ) of 0.14 at 25 V (120 Hz, 20 °C), supporting effective AC ripple attenuation in compact SMD layouts.
• Ripple & Leakage Characteristics — Low-frequency ripple current 300 mA (120 Hz), high-frequency ripple current 600 mA (10 kHz), and leakage current specified at 55 µA.
• Reliability & Endurance — Rated AEC-Q200 and designed for 2000 hours life at 105 °C, with operating temperature range from −55 °C to 105 °C.
• Package & Mounting — Chip-type can for SMD with dimensions φ10 × 7.7 mm and surface-mount land size recommendation L: 1.03 × W: 1.03 cm; supplied in embossed carrier taping for automated placement.
• RoHS Compliance — Manufactured in compliance with RoHS requirements.

Typical Applications

• Automotive Electronics — Suited for electronic control modules and other in-vehicle power circuits where AEC-Q200 qualification and elevated temperature endurance are required.
• Power Supply Decoupling on High-Density PCBs — Low impedance and compact SMD package support smoothing and transient suppression in compact power stages.
• Embedded Power Modules — Useful for DC–DC converter output filtering and local energy storage in space-constrained assemblies.

Unique Advantages

• Low-impedance design: 180 mΩ impedance and a tan δ of 0.14 (25 V, 120 Hz) reduce AC losses and improve ripple handling in compact layouts.
• High ripple capability: Rated for 300 mA (120 Hz) and 600 mA (10 kHz) ripple currents to support both low- and high-frequency power filtering demands.
• Automotive-capable qualification: AEC-Q200 rating and 2000-hour endurance at 105 °C align the part with demanding thermal and reliability requirements in vehicle electronics.
• Compact SMD form factor: φ10 × 7.7 mm chip-style can saves board area while enabling automated placement via embossed carrier taping.
• Controlled leakage: Leakage current specified at 55 µA for predictable bias performance in power circuits.
