UVR2A331MHD

The UVR2A331MHD is a radial‑lead aluminum electrolytic capacitor from Nichicon's UVR series, offering 330 µF capacitance at a 100 V rated voltage in a compact φ12.5×25L can. It is a miniature, general‑purpose device positioned for entertainment electronics and other applications that require reliable bulk capacitance in a through‑hole radial package.

Key attributes include a wide operating temperature range of −40°C to 85°C, endurance of 2000 hours at 85°C, RoHS compliance, and mass production availability—making it suitable for production designs that need predictable electrical behavior and supply continuity.

Key Features

• Electrical specification — 330 µF nominal capacitance with ±20% tolerance and a 100 V rated voltage; polarized construction for DC bulk energy storage.
• Ripple current capability — 760 mA at 120 Hz (low frequency) and 1.14 A at 10 kHz (high frequency), supporting both low‑ and high‑frequency ripple conditions.
• Leakage current — Specified leakage current of 990 µA, enabling predictable standby and bias characteristics after voltage application.
• Reliability and endurance — Designed for 2000 hours of rated voltage application at 85°C with capacitance change within ±20% and leakage current within initial specified limits.
• Temperature range — Rated for operation from −40°C to 85°C to cover a broad set of ambient conditions.
• Package and mounting — Radial lead can (φ12.5×25L) with 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for through‑hole assembly.
• Regulatory status — RoHS compliant and in mass production for continuity of supply.

Typical Applications

• Entertainment electronics — Designed as part of the UVR standard series for entertainment devices, providing bulk capacitance and ripple handling in power supply stages.
• General‑purpose power filtering — 100 V rating and 330 µF capacitance make it suitable for DC bus smoothing and energy storage in general‑purpose circuits.
• Through‑hole radial PCB assemblies — Radial lead configuration and compact φ12.5×25L package simplify placement in through‑hole boards and prototyping environments.

Unique Advantages

• High voltage capability: 100 V rating provides headroom for higher‑voltage DC rails without changing footprint.
• Dual‑frequency ripple handling: Specified ripple current at both 120 Hz and 10 kHz supports designs exposed to low‑ and high‑frequency AC ripple.
• Predictable endurance: 2000 hours at 85°C with specified capacitance and leakage limits enables designers to plan lifetime performance.
• Compact radial form factor: φ12.5×25L can with 5 mm lead spacing offers space‑efficient through‑hole mounting for production and repairable designs.
• Regulatory compliance and availability: RoHS compliant and in mass production, supporting procurement and assembly planning.
