UPS2W330MHD

The UPS2W330MHD is an aluminum electrolytic capacitor designed for compact, radial-lead power designs. It is a miniature, low-impedance polarized capacitor tailored for switching power supplies and general-purpose power filtering.

Key characteristics include a 450 V rated voltage, 33 µF capacitance, RoHS compliance, and operation across a wide temperature range, making it suitable for applications that require high-voltage smoothing in confined spaces.

Key Features

• High Voltage Rating — Rated at 450 V to support high-voltage DC bus and power supply applications.
• Capacitance and Tolerance — 33 µF nominal capacitance with ±20% tolerance for predictable bulk energy storage and filtering performance.
• Low Impedance / Ripple Handling — Specified ripple current of 145 mA at 120 Hz and 232 mA at 10 kHz to support switching supply ripple and decoupling.
• Wide Operating Temperature — Rated for operation from −25 °C to 105 °C with endurance specified as 3000 hours at 105 °C.
• Radial Lead Package — Radial can design with 7.5 mm lead spacing and polarized configuration for straightforward through-hole mounting.
• Compact Footprint — Physical size L: 3.55 × D: 1.8 cm with a seated height of 1.398 inch, suitable for space-constrained power modules.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk smoothing and ripple suppression on DC output rails in switching converters.
• General-Purpose Power Filtering — Energy storage and decoupling in power supply and general electronic circuits.
• High-Voltage DC Bus Circuits — Applicability where 450 V rating and 33 µF capacitance meet design requirements for bus filtering.

Unique Advantages

• High Voltage Capability: 450 V rating enables use on higher-voltage DC rails without series stacking.
• Compact, Radial Form Factor: Small L × D dimensions and radial leads simplify placement in tight board layouts while retaining through-hole reliability.
• Designed for Switching Environments: Low-impedance characteristics and specified ripple currents at 120 Hz and 10 kHz support switching converter performance.
• Wide Temperature Endurance: Operates to 105 °C with a 3000-hour endurance rating at that temperature for predictable lifetime in warm operating environments.
• Regulatory Compliance: RoHS compliance supports environmentally restricted designs and supply-chain requirements.
