UCD1C101MCL1GS

The UCD1C101MCL1GS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly. It delivers 100 µF capacitance at 16 V in a compact φ6.3 × 5.8 mm SMD can, targeting high-density PCBs and automated placement.

Engineered for demanding temperature and ripple environments, this part addresses power smoothing, decoupling and filtering needs in automotive and industrial electronic modules where AEC‑Q200 qualification and RoHS compliance are required.

Key Features

• Capacitance & Voltage — 100 µF rated capacitance with a 16 V rated voltage and tolerance of −20% to +20%, suitable for bulk decoupling and smoothing applications.
• Low Impedance Performance — Specified impedance 360 mΩ and tangent of loss angle (tan δ) 0.16 (measured at 20°C, 120 Hz), improving transient response and reducing voltage ripple.
• Ripple Current Handling — Low-frequency ripple current 120 mA (120 Hz) and high-frequency ripple current 240 mA (100 kHz), enabling use on both power rails and switching converter outputs.
• Leakage & Polarization — Polarized aluminum electrolytic design with a measured leakage current of 16 µA, consistent with long-term power storage on DC rails.
• Temperature & Endurance — Operating temperature range −55°C to +105°C with a rated endurance of 2000 hours at 105°C, for stable performance in elevated-temperature environments.
• Compact SMD Can Package — φ6.3 × 5.8 mm package (surface mount, radial can) with a recommended land size of 6.6 × 6.6 mm and supplied in embossed carrier taping for automated assembly.
• AEC‑Q200 Qualified & RoHS Compliant — Built to meet AEC‑Q200 requirements and RoHS directive compliance for regulated markets and reliability-focused designs.

Typical Applications

• Automotive Electronic Modules — Suited for decoupling and smoothing in automotive control and infotainment modules where AEC‑Q200 qualification and wide temperature range are required.
• DC‑DC Converter Output Filtering — Low impedance and high-frequency ripple current capability make it effective for output filters on switching regulators.
• Power Rail Decoupling — Compact SMD can provides bulk capacitance for point-of-load decoupling on dense PCBs.
• Industrial Electronics — Temperature tolerance to +105°C and 2000 h endurance at elevated temperature support use in industrial power and control systems.

Unique Advantages

• Compact, high-density format: φ6.3 × 5.8 mm SMD can saves board area while providing 100 µF capacitance for compact power designs.
• Measured low-loss behavior: tan δ 0.16 at 20°C/120 Hz and 360 mΩ impedance help minimize AC losses and thermal rise under ripple conditions.
• Frequency-flexible ripple handling: Rated ripple currents at both 120 Hz and 100 kHz broaden applicability across linear and switching supply domains.
• Qualified for demanding environments: AEC‑Q200 rating and −55°C to +105°C range support reliable operation in regulated and harsh temperature applications.
• Assembly-friendly packaging: Embossed carrier taping and SMD format enable automated placement for high-volume manufacturing.
• Regulatory compliance: RoHS compliance simplifies adoption in markets with restricted substances requirements.
