UPS1V331MPD

The UPS1V331MPD from Nichicon is a miniature, low‑impedance aluminum electrolytic capacitor in the UPS series designed for switching power supplies and general-purpose electronic equipment. It provides 330 µF capacitance at a 35 V rating in a compact radial-can package suitable for power smoothing and decoupling tasks where space and ripple performance matter.

Key value propositions include wide operating temperature (-55°C to 105°C), RoHS compliance, and engineered ripple handling backed by specified ripple current and impedance figures for reliable performance in demanding power applications.

Key Features

• Electrical Performance  330 µF capacitance at 35 V with ±20% tolerance; low impedance specified at 140 mΩ to support effective smoothing and transient suppression.
• Ripple Handling  Rated ripple current of 568 mA at 120 Hz and 800 mA at 10 kHz, enabling robust AC ripple endurance in switching environments.
• Wide Temperature Range  Operates from −55°C to +105°C, supporting use across broad ambient conditions.
• Reliability & Lifetime  Endurance rated at 2000 hours at 105°C (per series specifications), with leakage and tan δ limits defined by the UPS series endurance tests.
• Package & Mounting  Radial lead, can package with 5 mm lead spacing for through‑hole mounting and straightforward PCB integration.
• Environmental Compliance  Compliant with RoHS directives (2011/65/EU, (EU)2015/863) for lead‑free assembly requirements.

Typical Applications

• Switching Power Supplies  Designed specifically for use in switching power supply output filtering and energy storage to reduce ripple and stabilize rails.
• General-Purpose Power Filtering  Suitable for bulk decoupling and smoothing in a wide range of electronic equipment that requires compact, polarized capacitors.
• Power Conditioning Modules  Useful in modules where low impedance and defined ripple current capability help maintain stable voltage under load transients.

Unique Advantages

• Compact, High-Capacity Solution: 330 µF in a miniature radial can provides significant capacitance in limited PCB space.
• Low Impedance: 140 mΩ impedance supports lower ripple voltage and improved transient response in power rails.
• Measured Ripple Ratings: Published ripple currents at both 120 Hz and 10 kHz allow designers to match capacitor selection to switching frequencies.
• Wide Thermal Range: −55°C to +105°C operation broadens deployment options across temperature‑varying environments.
• RoHS Compliant: Meets current RoHS directive requirements for lead‑free assemblies.
• Radial Lead Convenience: Standard 5 mm lead spacing and through‑hole mounting simplify assembly and replacement.
