UUX1V221MNL1GS

The UUX1V221MNL1GS is a surface-mount aluminum electrolytic capacitor from Nichicon's UUX series. It is a chip-type, wide-temperature-range capacitor designed for applications that require bulk capacitance and stable performance across extended temperature and life conditions.

Key attributes include 220 µF capacitance at 35 V, AEC-Q200 qualification, and a rated operating range of −55 °C to 105 °C, making it suitable for demanding electronic systems that require reliable filtering and energy smoothing over long endurance periods.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 35 V, useful for bulk energy storage and smoothing on 12–24 V system rails.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20 °C, providing predictable capacitance for design calculations.
• Low Loss (tan δ) — tan δ = 0.12 (measured at 20 °C, 120 Hz), supporting stable AC performance and predictable dissipation.
• Ripple Current Capability — Low-frequency ripple current 450 mA (120 Hz) and high-frequency ripple current 585 mA (10 kHz), enabling effective filtering of both low- and high-frequency components.
• Leakage Current — Specified leakage current of 231 µA after 1 minute at 20 °C under rated voltage, allowing designers to budget leakage in low-current systems.
• Wide Temperature & Endurance — Operating temperature range −55 °C to 105 °C with rated endurance of 2000 hours at 105 °C, designed for long-term, high-temperature operation.
• Surface-Mount Can Package — Radial, can-style SMD package (chip type) with compact dimensions φ10 × 10L (L: 1 × D: 1 cm) and embossed carrier taping for automated placement.
• Automotive-Grade Reliability — AEC-Q200 rating for suitability in automotive electronic designs requiring industry-recognized component reliability.

Typical Applications

• Automotive Power Electronics — Bulk smoothing and decoupling on power rails where AEC-Q200 qualification and −55 °C to 105 °C operation are required.
• DC–DC Converters & Voltage Regulators — Energy storage and ripple suppression for converter outputs, leveraging the 220 µF capacitance and specified ripple current ratings.
• Control Modules and ECUs — Decoupling and transient buffering in control electronics that demand long endurance at elevated temperatures.
• Infotainment & Telematics Power Lines — Filtering and smoothing duties in vehicle electronics where stable capacitance and controlled leakage current are important.

Unique Advantages

• AEC-Q200 Qualified: Meets an industry automotive reliability standard, simplifying selection for vehicle electronics projects.
• High Endurance at Elevated Temperature: Rated for 2000 hours at 105 °C, enabling designs that require long-term stability in hot environments.
• Balanced Ripple Performance: Provides specified ripple current performance at both 120 Hz and 10 kHz, supporting mixed-frequency power filtering.
• Predictable AC Loss: Low tan δ (0.12 at 120 Hz, 20 °C) helps control dissipation in AC and ripple conditions.
• SMD Can in Embossed Taping: Compact chip-style can with embossed carrier taping supports automated assembly and compact PCB layouts.
• Wide Operating Temperature: −55 °C to 105 °C operation supports use across harsh thermal environments.
