UPW2W330MHD

The UPW2W330MHD is an aluminum electrolytic capacitor in a radial-can package designed for switching power supplies and automotive electronic systems. It offers a compact footprint with a 33 µF capacitance at a 450 V rating, delivering low impedance performance for high-frequency power conversion.

Engineered for reliability, the capacitor carries an AEC-Q200 rating and is specified for 8,000 hours at 105°C, making it suitable for demanding environments that require long life and stable ripple handling.

Key Features

• Electrical Rating — 33 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, suitable for high-voltage power rails where bulk energy storage is required.
• Low Impedance Performance — Marketed for low impedance operation in switching power supplies; specified ripple current of 145 mA at 120 Hz and 232 mA at 10 kHz supports both low- and high-frequency smoothing.
• Automotive-Grade Reliability — AEC-Q200 qualification and a rated lifetime of 8,000 hours at 105°C provide a defined reliability baseline for automotive and similarly demanding applications.
• Thermal and Lifetime Specification — Operating temperature range from −25°C to 105°C with endurance validated at elevated temperature (8,000 h at 105°C).
• Robust Radial-Lead Packaging — Radial lead, can-style package with 7.5 mm lead spacing and a compact footprint (L: 3.55 × D: 1.8 cm) for through-hole assembly and straightforward PCB layout.
• Polarized Design — Polarized aluminum electrolytic construction for DC power filtering and bulk decoupling in power converters.

Typical Applications

• Switching Power Supplies — Bulk and output filtering to reduce ripple and stabilize DC rails in switch-mode power supplies.
• Automotive Electronic Systems — Energy storage and ripple suppression in automotive power electronics where AEC-Q200 qualification and long-term high-temperature endurance are required.
• High-Frequency Power Conversion — Smoothing and decoupling in power converters operating at higher switching frequencies, supported by specified ripple current up to 10 kHz.

Unique Advantages

• High Voltage Capability — 450 V rating enables use on high-voltage DC rails without additional series components.
• Compact, Miniature Footprint — Small radial-can dimensions (3.55 × 1.8 cm) save board area compared with larger bulk capacitors while retaining significant capacitance.
• Defined High-Temperature Endurance — 8,000-hour rating at 105°C provides a measurable lifecycle expectation for design validation and reliability planning.
• High-Frequency Ripple Support — Specified ripple current at both 120 Hz and 10 kHz demonstrates suitability for smoothing across a broad frequency range common in modern power electronics.
• Through-Hole Mounting Simplicity — Radial lead construction with 7.5 mm lead spacing simplifies assembly and mechanical mounting in power modules and chassis-mounted supplies.
• Automotive Qualification — AEC-Q200 rating supports selection for vehicle electronics and other regulated applications requiring qualification documentation.
