UPS1C330MDD

The UPS1C330MDD is a miniature radial-lead aluminum electrolytic capacitor designed for general-purpose power filtering and decoupling in compact electronic assemblies. It belongs to Nichicon’s UPS series, which targets low-impedance performance suitable for switching power supplies and space-constrained power circuitry.

Key electrical characteristics include 33 µF capacitance at 16 V rating, a wide operating temperature range from −55°C to 105°C, and a rated endurance of 2000 hours at 105°C. Note: this part is listed as End Of Life.

Key Features

• Capacitance and Tolerance — 33 µF with tolerance of −20% to +20%, providing predictable bulk capacitance for general-purpose filtering.
• Rated Voltage — 16 V DC rating suitable for low-voltage power rails and supply decoupling.
• Low Impedance Design — UPS series miniaturized, low-impedance construction for improved ripple handling in switching power applications.
• Loss Characteristics — tan δ (DF) 0.16 measured at 20°C, 120 Hz, supporting stable AC performance at typical line frequencies.
• Ripple Current Capability — Low-frequency ripple current 27.2 mA at 120 Hz and high-frequency ripple current 160 mA at 10 kHz, enabling effective smoothing across a range of switching frequencies.
• Leakage and Endurance — Leakage current 15.84 µA (measured at 20°C after 1 minute) and rated life of 2000 hours at 105°C for reliable long-term operation under elevated temperature.
• Mechanical and Mounting — Compact φ5 × 11 mm can with radial leads, 2.0 mm lead spacing (±0.5 mm tolerance), sold bulk or bag packed for through-hole assemblies and prototyping.
• Temperature Range and Compliance — Operating range −55°C to +105°C and RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk and output smoothing where compact, low-impedance capacitors are required for ripple attenuation at switching frequencies.
• General Power Filtering — Supply decoupling and local energy storage on low-voltage rails in compact or densely populated PCBs.
• Through-Hole Prototyping and Repair — Radial-lead package and small footprint suit hand-assembled prototypes and legacy board replacements.

Unique Advantages

• Compact footprint: φ5 × 11 mm can provides useful capacitance in minimal board space for space-constrained designs.
• Designed for switching environments: Low-impedance series construction and specified ripple currents at 120 Hz and 10 kHz support performance across switching and line frequencies.
• Wide operating temperature: −55°C to +105°C rating allows deployment in varied thermal environments within the endurance limit.
• Through-hole convenience: Radial leads with 2.0 mm spacing simplify prototyping, manual assembly, and field replacement tasks.
• Traceable endurance specification: 2000-hour life at 105°C provides a quantifiable reliability baseline for thermal stress planning.
