UPS2F330MHD

The UPS2F330MHD from Nichicon is a miniature, low‑impedance aluminum electrolytic capacitor designed for switching power supplies and general‑purpose power applications. It is a radial‑lead, polarized can capacitor offering a high 315 V rating in a compact package, targeted at engineers needing space‑efficient DC filtering and ripple suppression.

Key value propositions include a wide operating temperature range, defined endurance at elevated temperature, and measurable ripple current capability—features that support stable power delivery in compact power systems.

Key Features

• Rated Voltage: 315 V — Suitable for higher‑voltage DC rails within the specified part parameters.
• Capacitance & Tolerance: 33 µF with ±20% tolerance (120 Hz, 20°C) for predictable bulk capacitance in power circuits.
• Low Impedance / Ripple Handling: Specified ripple current of 155 mA at 120 Hz and 248 mA at 10 kHz, enabling effective smoothing and decoupling in switching supplies.
• Wide Temperature Range: Rated for operation from −40°C to 105°C, supporting demanding thermal environments.
• Endurance: 3000 hours at 105°C — established lifetime metric for high‑temperature operation.
• Package & Mounting: Radial lead, can style with 7.5 mm lead spacing and compact dimensions (L: 2.5 × D: 1.6 cm); polarized construction for standard electrolytic applications.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies: Bulk smoothing and output decoupling where compact, low‑impedance capacitors are required for stable DC rails.
• Power Filtering: Local decoupling and ripple suppression on higher‑voltage power buses thanks to the 315 V rating and defined ripple current specs.
• General Purpose Power Electronics: Use in industrial and consumer power circuitry for energy storage and transient absorption within the specified temperature and lifetime parameters.

Unique Advantages

• High Voltage Capability: 315 V rating allows deployment on higher‑voltage DC rails without changing capacitor topology.
• Compact Footprint: Miniature can and radial lead form factor (L: 2.5 × D: 1.6 cm) conserve PCB area while maintaining required capacitance.
• Quantified Ripple Performance: Published ripple current values at both low and high frequencies (155 mA @120 Hz, 248 mA @10 kHz) make design margins and thermal management easier to calculate.
• Wide Operating Range with Defined Endurance: −40°C to 105°C rating plus 3000 hours at 105°C provides a clear reliability expectation for elevated‑temperature designs.
• Radial Lead Simplicity: Standard radial lead spacing (7.5 mm) simplifies through‑hole assembly and replacement in existing designs.
• RoHS Compliance: Meets current RoHS directives for environmentally regulated assemblies.
