UUD1V270MCL1GS

The UUD1V270MCL1GS is a chip-type, low-impedance aluminum electrolytic capacitor engineered for surface-mount use on high-density PC boards. Designed for automated assembly with carrier tape feed, this part delivers targeted performance for demanding environments, including automotive electronics where AEC-Q200 qualification is required.

Key value propositions include low impedance for ripple handling, a wide operating temperature range to +105°C, and a compact SMD radial can package that balances board area and capacitance for power conditioning and decoupling tasks.

Key Features

• Capacitance and Voltage — 27 µF rated capacitance at 35 V, with ±20% tolerance for predictable bulk and decoupling behavior.
• Low Impedance Profile — Specified impedance of 440 mΩ, supporting effective ripple attenuation; designed as a low-impedance chip type in the UUD series.
• Ripple Current Capability — 230 mA at 120 Hz and 345 mA at 10 kHz, enabling reliable performance under AC stress in power-supply circuits.
• Temperature and Endurance — Rated for −55°C to +105°C operation with a proven lifetime of 2000 hours at +105°C for the 6.3 mm diameter size.
• Reliability and Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), meeting automotive-grade reliability expectations.
• Package and Mounting — Chip-type radial can SMD package sized 6.3 × 5.8 mm (D × L) with recommended land pattern 6.6 × 6.6 mm; applicable to automatic mounting machines fed with carrier tape.
• Electrical Characteristics — Polarized aluminum electrolytic with leakage current spec of ≤ 0.01 CV or 3 μA (whichever is greater) after 2 minutes at 20°C; tan δ max for 35 V rating is 0.12 (0.14 for φ8 over) for effective dissipation control.
• Low-Temperature Stability — Impedance stability ratios for 35 V: Z(−25°C)/Z(+20°C) ≤ 2 and Z(−55°C)/Z(+20°C) ≤ 3, preserving decoupling performance across temperature extremes.

Typical Applications

• Automotive Electronic Modules — Suited to power-conditioning and decoupling in control units and modules where AEC-Q200 qualification and operation to +105°C are required.
• Power-Supply Output Stages — Low impedance and specified ripple current make the capacitor appropriate for smoothing and hold-up in DC–DC converter outputs.
• Embedded and High-Density PCBs — Chip-type SMD form factor and carrier-tape compatibility support automated assembly and compact board layouts in embedded systems.

Unique Advantages

• Automotive-Grade Qualification: AEC-Q200 status supports use in designs that demand established reliability processes and qualification.
• High-Temperature Endurance: Rated lifetime of 2000 hours at +105°C for the relevant case size provides predictable long-term behavior in thermally stressed assemblies.
• Compact SMD Can: 6.3 × 5.8 mm package with a small recommended land size enables high-density PCB designs without sacrificing capacitance.
• Measured Low Impedance: 440 mΩ impedance and controlled tan δ at the 35 V rating translate to effective ripple suppression and improved power-stability margins.
• Assembly Efficiency: Designed for carrier-tape automated mounting to streamline pick-and-place production workflows.
• Regulatory Compliance: RoHS-compliant construction aligns with modern manufacturing and supply requirements.
