UPS1E470MDD

The UPS1E470MDD is a Nichicon UPS series aluminum electrolytic capacitor specified at 47 µF and 25 V. It is a miniature, low‑impedance, polarized radial‑lead capacitor designed for switching power supplies and general‑purpose power filtering where compact size and wide operating temperature are required.

Key value comes from its compact radial can package, wide operating range (−55 °C to 105 °C), and specified ripple performance across low and high frequencies, making it suitable for dense power circuits and module-level filtering.

Key Features

• Capacitance & Rated Voltage — 47 µF nominal capacitance at a rated voltage of 25 V with ±20% tolerance.
• Wide Temperature Range — Rated for operation from −55 °C to 105 °C, supporting applications with broad thermal requirements.
• Low Impedance Design — Part of the UPS series engineered for low impedance, helping reduce ripple and improve stability in switching supplies.
• Ripple Current Performance — Specified ripple current of 27.2 mA at 120 Hz and 160 mA at 10 kHz for use in both low‑ and high‑frequency ripple environments.
• Endurance — Rated lifetime of 2000 hours at 105 °C, suitable for sustained elevated‑temperature operation.
• Leakage Current Specification — Series leakage characteristic: after 1 minute at rated voltage and 20 °C, leakage current not more than 0.03·C·V (µA).
• Package & Mounting — Radial lead, can‑style package with 2 mm lead spacing for through‑hole mounting and straightforward PCB placement.
• Compact Dimensions — Body size approximately L: 1.1 cm × D: 0.5 cm with a seated height max of 1.1 cm for space‑constrained designs.
• Polarized — Electrolytic, polarized device for DC power applications.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Local input/output filtering and bulk decoupling to smooth switching regulator outputs and improve transient response.
• Power Filtering in Consumer and Industrial Electronics — General‑purpose smoothing in compact power modules and PCB assemblies.
• Embedded Power Modules — Space‑constrained boards where a small, radial electrolytic is required for energy storage and ripple attenuation.

Unique Advantages

• Space‑efficient form factor: Small L×D footprint and low seated height enable high‑density PCB layouts and reduced enclosure volume.
• Designed for switching environments: Low‑impedance construction and specified ripple current at both 120 Hz and 10 kHz support filtering across a range of switching frequencies.
• Broad temperature tolerance: −55 °C to 105 °C rating provides reliable performance across demanding ambient conditions.
• Through‑hole ease of use: Radial lead, 2 mm spacing simplifies placement and soldering in manual or automated assembly processes for legacy and power designs.
• Endurance for elevated temperature operation: 2000‑hour rating at 105 °C gives designers a defined lifetime metric for thermal stress planning.
• Regulatory compliance: RoHS conformity supports environmentally restricted production requirements.
