UVR1A330MDD

The UVR1A330MDD is a miniature aluminum electrolytic capacitor from Nichicon’s UVR series. It is a radial-lead, polarized, standard-type capacitor specified at 33 µF and 10 V for general-purpose applications, with a compact φ5 × 11 mm footprint (D: 0.5 cm × L: 1.1 cm).

Designed for compact assemblies, the part combines low-frequency and high-frequency ripple capability, defined leakage and loss characteristics, and a 2000‑hour endurance rating at 85°C, making it suitable where a small, reliable electrolytic is required.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance with a tolerance of ±20% and a rated voltage of 10 V, providing predictable energy storage for low-voltage circuits.
• Low loss — Tangent of loss angle (tanδ) = 0.24 measured at 20°C, 120 Hz, 10 V, for defined dissipation characteristics in AC conditions.
• Ripple current capability — Low-frequency ripple current 85 mA (120 Hz) and high-frequency ripple current 170 mA (10 kHz), supporting both mains-level and higher-frequency ripple environments.
• Leakage current — Specified leakage current of 9.9 µA, allowing predictable standby and bias behavior after application of rated voltage.
• Reliability / Endurance — Endurance rated to 2000 hours at 85°C with capacitance, tanδ and leakage specified after the test, enabling stable long-term operation under elevated-temperature stress.
• Mechanical & mounting — Radial lead configuration with 2.0 mm lead spacing (±0.5 mm tolerance) and leaded can package for through-hole PCB assembly.
• Compact footprint — Size φ5 × 11 mm (D: 0.5 cm × L: 1.1 cm), suited to space-constrained board layouts.
• Environmental compliance — RoHS compliant per provided product data.
• Packaging options — Available in bulk (no terminal forming) or bag packing to accommodate different production workflows.

Typical Applications

• Consumer entertainment electronics — Part of Nichicon’s UVR standard series aimed at entertainment devices where a miniature electrolytic capacitor is required.
• General-purpose circuitry — Suitable for designers seeking a compact polarized capacitor for general-purpose power and signal circuits.
• Compact PCB assemblies — Small φ5 × 11 mm can and radial leads simplify placement in tight layouts where through-hole mounting is used.

Unique Advantages

• Space-efficient energy storage — 33 µF in a φ5 × 11 mm package helps minimize board area for power decoupling or charge storage in compact designs.
• Defined AC performance — Measured tanδ and specified ripple currents at both 120 Hz and 10 kHz provide clear design parameters for AC and switching environments.
• Predictable leakage behavior — Specified leakage current of 9.9 µA enables accurate budgeting of standby and bias currents.
• Elevated-temperature endurance — 2000 hours at 85°C endurance rating supports applications exposed to sustained elevated temperatures with known post-test limits.
• Through-hole mounting simplicity — Radial lead and standard lead spacing simplify integration into legacy and serviceable assemblies.
• RoHS compliance — Conforms to RoHS requirements as stated in the product data.
