UUA1A220MCL1GS

The UUA1A220MCL1GS is a surface-mount aluminum electrolytic capacitor from Nichicon's UUA series designed for compact power decoupling and filtering. It delivers 22 µF capacitance at a 10 V rating in a φ5 × 5.8 mm can-style SMD package, offering a combination of electrical performance and long‑life operation for demanding environments.

Targeted at automotive and other high-reliability electronics, this part combines AEC-Q200 qualification, RoHS compliance and an operational life rating at elevated temperature to address compact, high-density PCB designs requiring predictable performance over time.

Key Features

• Electrical Performance: 22 µF capacitance with a 10 V rated voltage and ±20% tolerance for bulk decoupling and smoothing in low-voltage power rails.
• Loss and Leakage: Tangent of loss angle (tan δ) of 0.24 (measured at 120 Hz, 20°C) and leakage current specified at 3 µA (per datasheet conditions), supporting stable performance in DC bias applications.
• Ripple Handling: Rated ripple current of 30 mA at 120 Hz and 45 mA at 10 kHz, allowing the capacitor to handle typical AC ripple and switching-noise conditions in power circuits.
• Temperature & Life: Operating range −55°C to +105°C with an operational life of 3000 hours at 105°C, matching endurance expectations for compact chip-type electrolytics.
• Package & Mounting: φ5 × 5.8 mm radial can SMD (chip type) with surface-mount land size L: 5.3 × W: 5.3 mm, designed for automated PCB assembly.
• Reliability & Compliance: AEC-Q200 qualified and RoHS compliant, supplied in embossed carrier taping and available in mass production quantities.

Typical Applications

• Automotive power rail decoupling: Local smoothing and ripple suppression on 10 V and lower rails in control modules, sensors and electronic actuators.
• ECU and control electronics: Bulk capacitance in compact, high-density PCB layouts where long life at elevated temperature is required.
• Sensor and interface modules: Stabilizing supply rails and filtering switching noise for analog front ends and digital interfaces in constrained spaces.

Unique Advantages

• Compact SMD can format: φ5 × 5.8 mm chip-type package provides 22 µF capacitance in a small board footprint for high-density designs.
• High-temperature endurance: Rated 3000 hours at 105°C, enabling reliable operation in elevated-temperature environments and applications with thermal stress.
• Automotive-grade qualification: AEC-Q200 rating supports deployment in automotive electronics and similarly demanding systems.
• Supply-chain friendly packaging: Embossed carrier taping and mass-production availability streamline automated pick-and-place assembly and volume procurement.
• Low leakage characteristic: Specified leakage current of 3 µA (per datasheet measurement conditions) helps preserve supply-hold characteristics and minimize standby losses.
