UVY1E331MPD

The UVY1E331MPD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UVY series, rated 330 µF at 25 V. It is a polarized, general-purpose electrolytic designed for applications that require compact capacitance with a wide operating temperature range and defined ripple performance.

Its core value proposition is a compact φ8 × 11.5 mm can package with 3.5 mm lead spacing, offering measurable ripple-handling capability, controlled leakage and endurance for designs that require reliable bulk capacitance across −55°C to 105°C.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance with a rated voltage of 25 V and a tolerance of −20% to +20%.
• Temperature Range — Rated for operation from −55°C to 105°C to support wide-temperature applications.
• Endurance — Specified lifetime of 1000 hours at 105°C (φ8 case endurance condition), supporting high-temperature endurance testing requirements.
• Ripple Current Performance — Low-frequency ripple current 275 mA at 120 Hz and high-frequency ripple current 412.5 mA at 10 kHz, enabling defined AC stress handling in power circuits.
• Leakage and Dissipation — Leakage current listed as 247.5 µA and tan δ (DF) of 0.16 measured at 20°C, 120 Hz, providing predictable dissipation and leakage behavior.
• Package and Mounting — Radial lead, polarized can with φ8 × 11.5 mm size and 3.5 mm lead spacing (±0.5 mm), available in bulk/no terminal forming or bag packing for flexible assembly options.
• Environmental Compliance — RoHS compliant, aligning with restricted-substances requirements.
• Production Status — Mass production availability for stable supply planning.

Typical Applications

• General Purpose Electronics — Where a 330 µF, 25 V polarized radial-lead electrolytic capacitor is required within a compact footprint and wide temperature range.
• Power Rail Bulk Capacitance — Suited for circuits needing defined ripple-handling capability at 120 Hz and 10 kHz frequency ranges, using the specified ripple current ratings.
• Repair and Prototyping — Available in bulk and bag packing for manual assembly and replacement in legacy or prototype boards that accept radial-lead cans with 3.5 mm lead spacing.

Unique Advantages

• Compact φ8 can size — Delivers 330 µF capacitance in a small radial-lead package (φ8 × 11.5 mm), helping reduce board area for space-constrained designs.
• Wide operating temperature — −55°C to 105°C rating provides design margin across harsh ambient conditions without adding extra thermal qualification steps.
• Defined ripple specifications — Published ripple current values at 120 Hz and 10 kHz allow engineers to size capacitors based on measured AC stress rather than estimates.
• Predictable leakage and dissipation — Specified leakage current and tan δ at standard measurement conditions enable easier thermal and leakage budgeting during design.
• Flexible packaging — Bulk (no terminal forming) and bag packing options support both manual and automated assembly workflows.
• RoHS compliant and in production — Complies with RoHS and is in mass production, supporting consistent supply and regulatory compatibility.
