UVY1A331MED

The UVY1A331MED is a radial-lead aluminum electrolytic capacitor from Nichicon's UVY series, offering 330 µF capacitance at a 10 V rating in a compact φ6.3 × 11 mm can. It is targeted at general-purpose electronic designs that require bulk capacitance and stable operation across a wide temperature range.

This capacitor combines low-frequency and high-frequency ripple handling with a wide operating temperature span (−55°C to 105°C) and a 1000-hour endurance at 105°C, providing a compact solution for space-constrained power and decoupling applications.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 10 V rated voltage and a tolerance of −20% to +20%.
• Loss Characteristics — Tangent of loss angle (tanδ) of 0.24 measured at 20°C, 120 Hz, providing a quantified dissipation factor for design analysis.
• Ripple Current Performance — Low-frequency ripple current of 210 mA (120 Hz) and high-frequency ripple current of 315 mA (10 kHz) to support AC and switching-related ripple in power circuits.
• Leakage Current — Specified leakage current of 99 µA for predictable idle-state behavior in power-storage applications.
• Mechanical & Mounting — Radial lead mounting with 2.5 mm lead spacing (±0.5 mm tolerance) in a φ6.3 × 11 mm package, suitable for compact through-hole layouts.
• Temperature & Endurance — Operating temperature range −55°C to 105°C with 1000 hours lifetime at 105°C, supporting elevated-temperature operation and long-term use cases.
• Compliance & Packaging — RoHS-compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.
• Polarized Aluminum Electrolytic — Polar construction for general-purpose DC filtering and energy-storage roles in electronic designs.

Typical Applications

• General-Purpose Electronics — For designs requiring a 330 µF, 10 V radial aluminum electrolytic capacitor with wide temperature capability and compact can size.
• Power Supply Filtering — Bulk capacitance and specified ripple current ratings support smoothing and decoupling in low-voltage power rails.
• Compact Through-Hole Assemblies — Small φ6.3 × 11 mm can and 2.5 mm lead spacing enable high-density placement in space-constrained PCBs.

Unique Advantages

• Compact Form Factor: φ6.3 × 11 mm can provides 330 µF capacitance in a small radial-lead package for space-limited boards.
• Wide Temperature Range: −55°C to 105°C rating enables deployment across a broad set of environmental conditions.
• Measured Ripple Capability: Specified ripple currents at 120 Hz and 10 kHz (210 mA and 315 mA respectively) allow designers to account for both low- and high-frequency ripple in power stages.
• Defined Loss and Leakage Metrics: A tanδ of 0.24 and leakage current of 99 µA provide clear parameters for thermal and idle-current budgeting.
• Endurance Data: 1000 hours at 105°C offers a quantified lifecycle metric for reliability planning in elevated-temperature applications.
• RoHS Compliant: Material compliance supports regulatory and environmental requirements.
