UPS1E330MDD

The UPS1E330MDD is a Nichicon UPS series miniature aluminum electrolytic capacitor designed for switching power supplies and general-purpose power filtering. It is a radial‑lead, polarized electrolytic capacitor offering compact size, low impedance, and a wide operating temperature range.

Engineered for applications that require a small footprint with reliable ripple handling, this part provides specified ripple current performance and is RoHS compliant.

Key Features

• Capacitance & Voltage — Rated at 33 µF and 25 V, suitable for decoupling and bulk filtering in low‑voltage power rails.
• Miniature Radial Package — Radial, can package with radial leads and 2 mm lead spacing for through‑hole assembly and compact PCB layouts; case dimensions L: 1.1 × D: 0.5 cm.
• Wide Temperature Range — Operating range from –55°C to +105°C to support applications across a broad ambient range.
• Endurance at Elevated Temperature — Rated lifetime of 2000 hours at 105°C, offering predictable aging characteristics under high‑temperature stress.
• Low Impedance & Ripple Performance — Specified ripple current of 27.2 mA at 120 Hz and 160 mA at 10 kHz to meet switching supply ripple requirements.
• Tolerance & Polarization — Capacitance tolerance ±20% (measured at 120 Hz, 20°C); polarized configuration for correct orientation in DC circuits.
• Leakage Current Specification (series) — Series leakage current: after 1 minute’s application of rated voltage at 20°C, leakage current is not more than 0.03CV (µA).
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and defined ripple handling improve voltage stability.
• General‑Purpose Power Filtering — Decoupling and smoothing in compact power modules and PCB power rails.
• Space‑Constrained Designs — Low‑profile, miniature can package fits tight board layouts and stacked component assemblies.

Unique Advantages

• Compact footprint — Small L×D dimensions help reduce board area and enable tighter component placement.
• Wide temperature capability — –55°C to +105°C rating allows use across varied thermal environments without derating form factor.
• Predictable high‑temperature endurance — 2000‑hour rating at 105°C provides design visibility for life and maintenance planning.
• Designed for switching environments — Low impedance construction and specified ripple current at both 120 Hz and 10 kHz support switching regulator use cases.
• RoHS compliant — Meets current environmental regulations for lead‑restricted assemblies.
• Through‑hole mounting simplicity — Radial lead format and 2 mm lead spacing ease prototyping and repairability.
