UVR1C331MPD

The UVR1C331MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVR series, offered in a compact φ8 × 11.5 mm can. Designed as a general-purpose part and listed in the UVR miniature series for entertainment electronics, it provides bulk capacitance and filtering capability in space-constrained assemblies.

With a rated voltage of 16 V, 330 µF capacitance, and a wide operating temperature range from −40 °C to 85 °C, this polarized capacitor is suited for power-smoothing, decoupling and energy-storage roles where compact size, endurance and measurable ripple performance are required.

Key Features

• Capacitance & Voltage — 330 µF capacitance at a rated voltage of 16 V with capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Compact Radial Can — φ8 × 11.5 mm can in a radial-lead package with 3.5 mm lead spacing (±0.5 mm), suitable for through-hole PCB layouts.
• Ripple Current Performance — Low-frequency ripple capability of 370 mA at 120 Hz and high-frequency ripple capability of 555 mA at 10 kHz, enabling effective filtering across a range of switching and line frequencies.
• Loss and Leakage — Dissipation factor (tanδ) of 0.2 measured at 20 °C, 120 Hz, and a specified leakage current of 158.4 µA.
• Endurance & Temperature Range — Rated for 2,000 hours at 85 °C with an operating range from −40 °C to 85 °C, providing predictable life characteristics under elevated temperature stress.
• Packaging & Production — Available in bulk (no terminal forming) or bag packing; product is in mass production and RoHS compliant.

Typical Applications

• Consumer / Entertainment Electronics — Bulk smoothing and decoupling in audio/video players, set-top boxes and related miniature electronics where the UVR series is targeted.
• Power Supply Filtering — Output filtering and local energy reservoir for low-voltage DC rails in small power supplies and regulators.
• Embedded Control Boards — Decoupling and transient support on microcontroller and peripheral power domains in compact, through-hole assemblies.
• General-Purpose Electronics — Applications that require a compact polarized electrolytic with defined ripple handling and 2,000 h endurance at 85 °C.

Unique Advantages

• Compact footprint with radial leads: The φ8 × 11.5 mm can and 3.5 mm lead spacing save PCB area while keeping familiar through-hole mounting and mechanical stability.
• Measured ripple performance: Specified ripple currents at both 120 Hz (370 mA) and 10 kHz (555 mA) allow designers to size the capacitor confidently for both line-frequency and switching-frequency filtering.
• Controlled loss and leakage: A dissipation factor of 0.2 (20 °C, 120 Hz) and defined leakage current (158.4 µA) contribute to predictable filtering behavior and power loss budgeting.
• Endurance under elevated temperature: Rated for 2,000 hours at 85 °C, providing defined long-term performance characteristics for designs that operate in warm environments.
• RoHS compliant and production-ready: Meets RoHS requirements and is available in mass production with standard bulk or bag packing options to support prototyping through production volumes.
