UUD1A270MCL1GS

The UUD1A270MCL1GS is a 27 µF, 10 V aluminum electrolytic chip capacitor from Nichicon's UUD series, designed for surface-mount assembly and high-density PCBs. It combines a compact φ5 × 5.8 mm can-style SMD package with low-impedance characteristics for stable decoupling and filtering in constrained board space.

Targeted for automotive electronics, the part is AEC-Q200 qualified and RoHS compliant, offering a wide operating temperature range of -55°C to 105°C and a rated lifetime of 2000 hours at 105°C. Embossed carrier taping supports automated placement for volume production.

Key Features

• Capacitance & Voltage — 27 µF nominal capacitance at a rated voltage of 10 V, suitable for low-voltage power rail decoupling.
• Low-Impedance Chip Type — Chip-style, low-impedance construction with an impedance of 760 mOhm, optimized for reduced ESR in SMD applications.
• Ripple Current Handling — Rated for 150 mA at 120 Hz (low frequency) and 225 mA at 10 kHz (high frequency), enabling effective ripple smoothing across a range of switching frequencies.
• Size & Mounting — Compact radial can SMD package (φ5 × 5.8 mm; L: 5.8 × D: 5 mm) with surface-mount land recommendation of 5.3 × 5.3 mm and embossed carrier taping for automatic mounting.
• Reliability & Lifetime — AEC-Q200 qualified with an endurance rating of 2000 hours at 105°C, supporting demanding temperature and duty-cycle environments.
• Leakage & Tolerance — Low leakage current (typical limit 3 µA) and capacitance tolerance of ±20% at 120 Hz, 20°C for predictable performance.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive power rails — Local decoupling and smoothing for 10 V systems in vehicle electronics, leveraging AEC-Q200 qualification and high-temperature endurance.
• ECU and control modules — Compact SMD form factor and embossed carrier taping enable automated assembly for engine control, body control or sensor interface modules.
• Infotainment and telematics — Ripple suppression and low impedance behavior help stabilize audio, display and communication power supplies.

Unique Advantages

• Automotive-ready qualification — AEC-Q200 rating provides an established reliability baseline for vehicle electronics design and validation.
• Compact SMD can package — φ5 × 5.8 mm size and surface-mount compatibility reduce board footprint while supporting automated placement via embossed carrier taping.
• Measured low impedance — 760 mOhm impedance contributes to effective ESR performance for decoupling and ripple attenuation.
• Broad ripple capability — Distinct ripple current ratings at 120 Hz and 10 kHz (150 mA / 225 mA) address both low-frequency and switching-frequency smoothing needs.
• High-temperature endurance — Rated for 2000 hours at 105°C, enabling use in elevated-temperature zones common in automotive and industrial environments.
• Regulatory compliance — RoHS conformity supports environmental and regulatory requirements for modern electronics manufacturing.
