UVK2A331MHD

The UVK2A331MHD is a Nichicon UVK series aluminum electrolytic capacitor offering 330 µF capacitance at a 100 V rating in a radial-lead can. Designed for general-purpose power applications, it combines high-voltage capability with compact, miniature sizing for space-constrained boards.

Key measured performance metrics include low loss (tanδ), defined ripple current ratings across low and high frequencies, controlled leakage current, and a 2000-hour endurance rating at 85°C—making this part suitable where predictable lifetime and robust ripple handling are required.

Key Features

• Core Electricals — 330 µF nominal capacitance with a rated voltage of 100 V and capacitance tolerance of ±20% (120 Hz, 20°C).
• Low Loss Performance — tanδ (DF) specified at 0.08 with measurement conditions of 20°C and 120 Hz, supporting stable AC performance at the rated voltage.
• Ripple Current Handling — Low-frequency ripple current of 760 mA at 120 Hz and high-frequency ripple current of 1.14 A at 10 kHz to support smoothing and filtering duties across a range of switching frequencies.
• Leakage and Endurance — Specified leakage current of 990 µA and endurance of 2000 hours at 85°C with the rated voltage applied, providing predictable aging characteristics.
• Thermal Range — Operating temperature range from −40°C to +85°C for use in standard industrial and commercial environments.
• Compact Radial Package — Miniature radial can with physical size φ12.5 × 25L and lead spacing of 5.0 mm (lead spacing tolerance ±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant and provided in mass-production status for consistent supply.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling in high-voltage DC power rails where 100 V rating and 330 µF capacitance are required.
• DC/DC Converters — Input/output filtering for converters that demand defined ripple current capability at both low and high switching frequencies.
• Industrial Electronics — Energy storage and filtering in general-purpose industrial control and instrumentation systems operating within −40°C to +85°C.

Unique Advantages

• High Voltage in a Compact Footprint: 100 V rating combined with a φ12.5 can size allows higher-voltage designs without a large case increase.
• Dual-Frequency Ripple Specification: Separate ripple current values for 120 Hz and 10 kHz enable designers to size capacitors according to both line-frequency and switching-frequency stress.
• Predictable Endurance: 2000 hours at 85°C with rated voltage applied gives a clear baseline for life-limited design planning.
• Controlled Loss and Leakage: Specified tanδ and leakage current figures support thermal and leakage budgeting in precision power designs.
• Ready for Production: RoHS compliance and mass-production status simplify procurement and regulatory alignment for volume builds.
