UPS1A330MDD

The UPS1A330MDD is a miniature, high‑reliability aluminum electrolytic capacitor from Nichicon’s UPS series. It is a radial‑lead, polarized capacitor optimized for low‑impedance performance and intended for switching power supplies and general‑purpose power filtering.

Key characteristics include 33 µF capacitance at 10 V rated voltage, a wide operating temperature range of −55°C to 105°C, and RoHS compliance. Status: End Of Life.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 10 V and tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Low‑Loss Performance — tanδ (DF) of 0.20 measured at 20°C, 120 Hz, supporting low dissipation in power applications.
• Ripple Handling — Low‑frequency ripple current of 27.2 mA at 120 Hz and high‑frequency ripple current of 160 mA at 10 kHz, enabling effective smoothing in switching circuits.
• Leakage Current — Specified leakage current of 9.9 µA (after 1 minute at 20°C), useful for predictable bias performance in low‑voltage designs.
• High‑Temperature Endurance — Endurance specified as 2000 hours at 105°C under rated DC bias plus rated ripple current.
• Compact Radial Package — Can size φ5 × 11 mm with 2.0 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole assemblies and compact PCB layouts.
• Environmental — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Low‑impedance, miniature capacitor for output smoothing and local decoupling in switch‑mode power supplies.
• Low‑Voltage Power Filtering — 10 V rating and defined leakage/ripple characteristics suit low‑voltage power rails and regulation circuits.
• General Purpose Electronics — Radial lead form and compact footprint make it appropriate for general power filtering in small assemblies.

Unique Advantages

• Compact form factor: φ5 × 11 mm can with 2 mm lead spacing lets designers save board area while retaining through‑hole robustness.
• Defined ripple and leakage specs: Published low‑ and high‑frequency ripple currents plus measured leakage current enable predictable thermal and bias design margins.
• Wide operating temperature: −55°C to 105°C range supports reliable operation across broad environmental conditions.
• High‑temperature endurance: Rated endurance of 2000 hours at 105°C under bias and ripple current provides a clear reliability baseline for power designs.
• RoHS compliant: Meets applicable RoHS requirements for environmentally constrained designs.
• Radial lead convenience: Through‑hole mounting simplifies prototyping and assembly for power modules and legacy PCB designs.
