UVK1E331MPD

The UVK1E331MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVK series, specified at 330 µF and 25 V. It delivers compact bulk capacitance in a miniature φ8 × 11.5 mm can package with radial through‑hole leads for straightforward PCB mounting.

Designed for general-purpose electronics, this capacitor combines measurable ripple-handling capability, low leakage, and extended endurance for designs that require reliable smoothing, decoupling and bulk energy storage within a −40 °C to +85 °C operating window.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20% for predictable bulk energy storage and filtering.
• Ripple Current Handling — Low-frequency ripple current 390 mA (120 Hz) and high-frequency ripple current 585 mA (10 kHz) to support common power-supply filtering and decoupling tasks.
• Loss Characteristics — Tangent of loss angle (tanδ) of 0.16 measured at 20 °C, 120 Hz, enabling assessment of dissipation under AC conditions.
• Leakage Current — Specified leakage current of 247.5 µA for predictable standby and bias behavior in powered circuits.
• Temperature and Endurance — Rated for operation from −40 °C to +85 °C with an endurance life of 2000 hours at 85 °C under rated voltage conditions.
• Package and Mounting — Radial lead, can-style package (φ8 × 11.5 mm), lead spacing 3.5 mm ±0.5 mm, available in bulk or bag packing for flexible procurement and assembly.
• Polarized Design — Polarized aluminum electrolytic construction for DC power applications requiring polarity-aware bulk capacitance.
• RoHS Compliant — Meets RoHS requirements for use in regulated supply chains.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction in low-voltage DC power supplies where 330 µF at 25 V is required.
• Decoupling and Bulk Energy Storage — Local energy reservoir and decoupling for regulated rails and intermediate power stages, leveraging the part’s ripple-current ratings and capacitance.
• General-Purpose Electronic Modules — Through-hole implementations in consumer and industrial PCBs that need reliable, space-efficient electrolytic capacitance.

Unique Advantages

• Compact Miniature Footprint — φ8 × 11.5 mm can size provides 330 µF of capacitance in a small volume for space-constrained through-hole designs.
• Measurable Ripple Performance — Defined low- and high-frequency ripple current specs (390 mA at 120 Hz, 585 mA at 10 kHz) allow designers to match the capacitor to expected AC stress conditions.
• Predictable Loss and Leakage — Specified tanδ and leakage current simplify thermal and standby loss calculations in power budgets.
• Durability Under Elevated Temperature — 2000-hour endurance at 85 °C supports longer service life expectations for sustained operating environments.
• Easy Through-Hole Assembly — Radial-lead format and standard 3.5 mm lead spacing enable straightforward insertion and soldering on conventional PCBs.
• RoHS Compliance — Facilitates use in RoHS-regulated products and supply chains.
