UPW1V330MDD

The UPW1V330MDD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for compact power applications. It provides 33 µF capacitance at a 35 V rating with polarized radial leads and a compact φ5 × 11 mm package footprint.

Engineered for demanding operating conditions, this part offers specified ripple current performance at both low and high frequencies, a wide operating temperature range from −55°C to 105°C, and defined endurance at elevated temperature for reliable power smoothing in space-constrained designs.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 35 V and capacitance tolerance of −20% to +20%.
• Electrical Loss & Leakage — Specified tangent of loss angle (tanδ) of 0.12 measured at 20°C, 120 Hz, and a measured leakage current of 34.65 µA.
• Ripple Current Performance — Low-frequency ripple current of 54 mA at 120 Hz and high-frequency ripple current of 180 mA at 10 kHz, supporting both power-line and switching-frequency decoupling.
• Temperature & Endurance — Operating temperature range −55°C to 105°C with an endurance rating of 2000 hours at 105°C.
• Package & Mounting — Radial lead, polarized can with φ5 × 11 mm size, 2.0 mm lead spacing (±0.5 mm), and available in bulk or bag packaging.
• Qualification — Rated with AEC‑Q200 (passive component qualification), indicating suitability for demanding environments where this rating is required.

Typical Applications

• Switching Power Supplies — Used for output smoothing and decoupling where a compact, low-impedance capacitor is needed at switching frequencies.
• Automotive Electronics — Suitable for automotive electronic modules that require AEC‑Q200‑rated passive components and a wide −55°C to 105°C operating range.
• Compact Power Modules — Fits space-constrained boards and through-hole assemblies needing reliable bulk capacitance and defined ripple handling.

Unique Advantages

• Defined ripple capability across frequencies — Separate ripple current ratings for 120 Hz and 10 kHz let designers size decoupling for both low-frequency and switching-frequency loads.
• Space-saving miniature package — φ5 × 11 mm can and 2 mm lead spacing make the part well suited to compact PCB layouts and tight through-hole densities.
• Wide temperature tolerance — −55°C to 105°C operation supports designs exposed to broad thermal ranges without losing specified performance.
• AEC‑Q200 rating — Provides a recognized qualification level for reliability in demanding applications where passive component ratings are required.
• Measured loss and leakage data — Specified tanδ and leakage current values provide clear inputs for ECC, stability, and power-loss calculations during design validation.
