UPS1E331MPD

The UPS1E331MPD is a Nichicon aluminum electrolytic capacitor designed for miniature, low-impedance power filtering in switching power supplies and general-purpose power circuits. It is a radial-lead, polarized can-type capacitor with a 330 μF capacitance and a 25 V rated voltage.

Engineered for environments requiring a wide temperature range and reliable ripple handling, the UPS1E331MPD supports operation from −55°C to 105°C and is RoHS compliant.

Key Features

• Capacitance & Voltage — 330 μF nominal capacitance at a 25 V rated voltage suitable for bulk decoupling and energy storage in power rails.
• Low Impedance — Specified impedance of 190 mΩ, enabling effective high-frequency smoothing in switching regulator outputs.
• Wide Temperature Range — Rated for operation from −55°C to 105°C, supporting designs that require thermal resilience.
• Radial Lead Package — Radial, can-style package with 5 mm lead spacing for through-hole mounting and straightforward PCB layout.
• Compact Footprint — Physical size L: 1.25 × D: 1.00 cm for space-constrained power modules.
• Ripple Current Capability — Rated ripple current of 426 mA at 120 Hz and 600 mA at 10 kHz to handle typical switching supply ripple loads.
• Endurance — Designed for 2000 hours at 105°C (specified lifetime for this case size), providing predictable aging for high-temperature applications.
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.

Typical Applications

• Switching Power Supplies — Bulk and output filtering to stabilize DC rails and reduce ripple in switch-mode power designs.
• Power Conversion Modules — Energy storage and decoupling in DC–DC converters and regulator modules where a compact radial capacitor is needed.
• Industrial Electronics — General-purpose power filtering in control and instrumentation equipment operating across a wide temperature range.
• Consumer Electronics Power Rails — Local energy storage and smoothing on PCB power rails in compact consumer devices.

Unique Advantages

• Space-efficient design: The small can (1.25 × 1.00 cm) and 5 mm lead spacing let you maintain bulk capacitance without a large PCB footprint.
• Improved ripple handling: Specified ripple current values at 120 Hz and 10 kHz support reliable smoothing across common switching frequencies.
• Wide operating temperature: −55°C to 105°C rating helps ensure consistent performance in both cold-start and high-temperature environments.
• Predictable lifetime at elevated temperature: 2000 hours at 105°C enables designers to plan for long-term performance in thermally demanding applications.
• RoHS compliance: Meets current restricted-substance directives for deployment in regulated markets.
• Trusted manufacturer: Part of Nichicon’s UPS series, providing consistent electrical and mechanical characteristics for production designs.
