UEP1E470MED

The UEP1E470MED is a bi-polarized aluminum electrolytic capacitor from Nichicon's UEP series, engineered for wide temperature operation and general-purpose radial-lead applications. It is specified for 25 V rated voltage and 470 µF capacitance with a ±20% tolerance, making it suitable for AC-coupling and dual-polarity circuits as well as power filtering in equipment that must tolerate extreme temperatures.

Key value propositions include bi-polar construction for reversed-polarity operation, a wide operating temperature range from −55 °C to +105 °C, and a 1000-hour endurance rating at 105 °C for reliable performance in demanding environments.

Key Features

• Bi-Polarized Construction  Designed for applications requiring no polarity, enabling AC coupling and circuits where polarity may reverse.
• Wide Temperature Range  Specified to operate from −55 °C to +105 °C for use across a broad set of environmental conditions.
• Electrical Ratings  25 V rated voltage with 470 µF capacitance and ±20% tolerance, offering high capacitance in a compact radial-can package.
• Endurance and Reliability  Rated for 1000 hours at 105 °C (with polarity inversion every 250 hours as per endurance test conditions), supporting long-term thermal endurance.
• Leakage and Ripple Performance  Specified leakage current of 352.5 µA (after initial application conditions) and rated ripple current of 67 mA at 120 Hz and 134 mA at 10 kHz.
• Package and Mounting  Radial lead, can-style package with lead spacing of 5.0 mm and physical size φ12.5 × 20 mm; supplied in bulk (no terminal forming) or bag packing.
• RoHS Compliant  Conforms to RoHS directives for lead-free materials and environmental compliance.

Typical Applications

• General-purpose power filtering  Bulk capacitance for smoothing and decoupling in power supplies and regulator stages across a wide temperature range.
• AC-coupling and signal paths  Bi-polar construction enables use in AC coupling and bipolar signal-conditioning circuits where polarity reversal can occur.
• Industrial and instrumentation electronics  Filter and energy-storage applications in sensor interfaces, measurement modules, and control electronics exposed to temperature extremes.
• Embedded and board-level designs  Radial-lead can package simplifies through-hole mounting for legacy and mixed-technology PCBs requiring stable capacitance at elevated temperatures.

Unique Advantages

• Bi-polar versatility: Eliminates the need for polarity-sensitive placement and supports AC or reversed-polarity conditions without additional circuitry.
• Wide operating temperature: −55 °C to +105 °C rating allows deployment in cold-start and high-temperature scenarios with maintained performance.
• Proven endurance: 1000-hour rating at 105 °C (with polarity inversion test regimen) provides a measurable baseline for long-term thermal stability.
• Practical ripple handling: Published ripple currents at 120 Hz and 10 kHz help designers evaluate thermal and ripple-aging performance for their specific frequency environments.
• Compact radial form factor: φ12.5 × 20 mm can and 5.0 mm lead spacing balance high capacitance with straightforward through-hole assembly.
• Regulatory compliance: RoHS compliance supports use in designs targeting regulatory conformance for hazardous substance restrictions.
