UVR1A333MRD

The UVR1A333MRD is a radial-lead aluminum electrolytic capacitor from Nichicon's UVR series, offering 33,000 µF capacitance at a 10 V rating. It is a miniature-sized, polarized capacitor designed for general-purpose applications, with the UVR series noted for use in entertainment electronics.

Key attributes include high bulk capacitance at low voltage, measurable ripple current capability across low and high frequencies, and an endurance rating specified for long-term operation at elevated temperature.

Key Features

• High Capacitance — 33,000 µF nominal capacitance (33 mF) for bulk energy storage and low-voltage smoothing.
• Rated Voltage — 10 V working voltage suitable for low-voltage power rails.
• Ripple Current Handling — 4.5 A low-frequency ripple current (120 Hz) and 5.175 A high-frequency ripple current (10 kHz) for demanding ripple environments.
• Endurance — 2000 hours at 85 °C rated life, with specified post-test limits for capacitance, tan δ, and leakage current.
• Temperature Range — Operates from −40 °C to +85 °C.
• Form Factor — Radial, can-style package with dimensions φ22 × 50 mm (diameter × length) and 10 mm lead spacing (±0.5 mm).
• Leakage Current — Specified leakage current of 9,900 µA for the part.
• Capacitance Tolerance — −20% to +20% tolerance at 120 Hz, 20 °C.
• RoHS Compliance — Compliant with RoHS requirements.
• Packaging Options — Available in bulk (no terminal forming) or bag packing.

Typical Applications

• Entertainment Electronics — Suited for power supply smoothing and bulk decoupling within entertainment systems, consistent with the UVR series target.
• General-Purpose Power Filtering — High capacitance and specified ripple current ratings make it applicable for low-voltage DC rail filtering and hold-up.
• Space-Conscious Designs — Miniature-sized radial can provides large capacitance in a compact φ22 × 50 mm package for designs with limited board area.

Unique Advantages

• Large Bulk Energy Storage: 33,000 µF at 10 V supplies substantial charge storage for smoothing and transient buffering on low-voltage rails.
• Dual-Frequency Ripple Capability: Rated ripple currents at both 120 Hz (4.5 A) and 10 kHz (5.175 A) support a range of power-conversion and filtering scenarios.
• Elevated Endurance Rating: 2000 hours at 85 °C provides a defined life expectation for designs that operate at elevated temperatures.
• Wide Operating Temperature: −40 °C to +85 °C operation supports deployment across varied environmental conditions.
• Compact Radial Package: φ22 × 50 mm can and 10 mm lead spacing deliver high capacitance in a standard radial form factor compatible with through-hole assembly.
• Regulatory Compliance: RoHS compliance helps meet regulatory requirements for environmental restrictions.
