UVK1A333MRD

The UVK1A333MRD is a miniature aluminum electrolytic capacitor from Nichicon's UVK series, configured as a radial‑lead, polarized can. It delivers 33,000 µF capacitance at a 10 V rating in a compact φ22 × 50 mm can (lead spacing 10 mm), designed for general‑purpose electronic designs that require high capacitance at low voltage.

Key electrical attributes include defined ripple current capability (4.5 A at 120 Hz, 5.175 A at 10 kHz), a capacitance tolerance of -20% to +20%, and an endurance rating of 2000 hours at 85 °C. RoHS compliant. Status: End Of Life.

Key Features

• High Capacitance: 33,000 µF nominal capacitance provides substantial energy storage in a compact radial can (φ22 × 50 mm).
• Rated Voltage & Tolerance: 10 V rated voltage with capacitance tolerance of -20% to +20% for predictable design margins.
• Ripple Current Performance: Low‑frequency ripple current 4.5 A (120 Hz) and high‑frequency ripple current 5.175 A (10 kHz), specified for assessed AC load handling.
• Leakage Current: Specified leakage current of 9900 µA for initial DC leakage characterization.
• Endurance & Temperature Range: Rated for 2000 hours at 85 °C; operating temperature range -40 °C to 85 °C.
• Package & Mounting: Radial lead (polarized) can with 10 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for through‑hole assembly and replacement.
• Regulatory: RoHS compliant material status.

Typical Applications

• General Purpose Electronics — Designed for general‑purpose circuits requiring 33,000 µF at 10 V in a through‑hole radial package with operation from -40 °C to 85 °C.
• Low‑Voltage Bulk Capacitance — Suited to designs that need substantial low‑voltage capacitance within a compact can, supported by specified ripple current ratings.
• Through‑Hole Assembly and Repair — Radial lead format and bulk/bag packaging simplify manual assembly, prototyping, and field replacement.

Unique Advantages

• High volumetric capacitance: 33,000 µF in a φ22 × 50 mm can enables significant charge storage where PCB area is limited.
• Defined ripple handling: Specified ripple currents at both low and high frequency (4.5 A @120 Hz, 5.175 A @10 kHz) allow designers to size capacitors against expected AC stress.
• Extended endurance at elevated temperature: 2000 hours at 85 °C provides a quantifiable life expectation for thermal design planning.
• Wide operating temperature range: -40 °C to 85 °C supports deployment across a broad set of environmental conditions.
• Through‑hole convenience: Radial lead and bulk/bag packaging simplify insertion, replacement, and repair workflows.
• RoHS compliance: Meets RoHS requirements for lead‑restricted applications.
