UPW1C330MDD

The UPW1C330MDD is a 33 µF, 16 V radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series. It is a miniature, low-impedance, high-reliability electrolytic designed for power-filtering roles in compact electronic systems.

With a wide operating temperature range and AEC-Q200 rating, this radial through-hole capacitor is suited to demanding environments where temperature stability, ripple handling, and long-term endurance are required.

Key Features

• Capacitance & Rated Voltage — 33 µF nominal capacitance with tolerance ±20% and a rated voltage of 16 V.
• Low Loss (tan δ) — Dissipation factor (tanδ) of 0.16 measured at 20°C, 120 Hz, supporting efficient operation in AC and switching environments.
• Ripple Current Capability — Low-frequency ripple current 54 mA at 120 Hz and high-frequency ripple current 180 mA at 10 kHz, enabling effective smoothing in switching supplies.
• Frequency Coefficient for Ripple — For 15–47 µF parts, ripple current frequency coefficients are: 50 Hz = 0.20, 120 Hz = 0.30, 300 Hz = 0.50, 1 kHz = 0.80, ≥10 kHz = 1.00.
• Leakage Current — Specified leakage current of 15.84 µA.
• Temperature & Endurance — Rated for operation from −55°C to +105°C with an endurance rating of 2000 hours at 105°C.
• Package & Mechanical — Miniature radial can: diameter φ5 × length 11 mm (L: 1.1 × D: 0.5 cm), radial lead spacing 2.0 mm (±0.5 mm), polarized for through-hole mounting.
• Reliability & Qualification — Part of the UPW series designed for high reliability; specified with an AEC-Q200 rating noted in the product specifications.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit production handling needs.

Typical Applications

• Switching Power Supplies — Smoothing and output filtering in compact switching regulators where low impedance and miniature size are required.
• Automotive Electronic Systems — Suited for automotive applications (AEC-Q200 listed) that require durable capacitors across −55°C to +105°C.
• Power Supply Decoupling — Local decoupling and noise suppression in compact power modules and DC-DC converter outputs.
• Through-Hole Power Designs — Radial-lead format makes it appropriate for through-hole boards and legacy or robust mechanical mounting requirements.

Unique Advantages

• Compact footprint: φ5 × 11 mm package delivers 33 µF capacitance in a miniature radial can for space-constrained designs.
• Low-impedance performance: Series design and specified tanδ support efficient energy handling in switching environments, improving ripple suppression.
• Wide temperature range: −55°C to +105°C operating range supports reliable performance across harsh thermal conditions.
• High-frequency ripple capability: 180 mA at 10 kHz plus documented frequency coefficients make the part predictable across switching frequencies.
• Automotive-capable qualification: AEC-Q200 listing aligns the part to designs targeting automotive system requirements.
• Through-hole robustness: Radial leads and defined lead spacing (2.0 mm ±0.5 mm) simplify mounting and mechanical retention in thru-hole assemblies.
