UPV1E390MFD

The UPV1E390MFD from Nichicon is a miniature, low‑impedance aluminum electrolytic capacitor in a radial can package designed for general‑purpose use. It delivers compact energy storage and filtering capability with a rated capacitance of 39 µF at 25 V, polarized construction, and radial lead mounting.

Engineered for elevated operating conditions, this capacitor supports an operating temperature range of –55 °C to +105 °C and a demonstrated load life of 5000 hours at +105 °C, making it suitable for compact electronics that require stable performance and long life at higher temperatures. The part is RoHS compliant.

Key Features

• Electrical Performance — 39 µF capacitance at 25 V with ±20% tolerance, offering predictable charge storage for decoupling and smoothing applications.
• Low Impedance Design — Part of Nichicon’s low‑impedance UPV series, optimized for reduced ESR to support effective ripple handling and stable circuit performance.
• Ripple Current Ratings — Rated ripple handling of 91 mA at 120 Hz and 175 mA at 200 kHz, providing concrete limits for AC stress in filter and supply circuits.
• High‑Temperature Endurance — Specified for 5000 hours of load life at +105 °C, with defined endurance and shelf‑life characteristics from the UPV series.
• Package & Mounting — Radial lead, can‑style package with 2 mm lead spacing and compact dimensions (L: 1.1 cm × D: 0.5 cm), suitable for tight board layouts.
• Wide Operating Range & Polarized Construction — Operates from –55 °C to +105 °C and is polarized for DC applications requiring electrolytic capacitance.
• Environmental Compliance — RoHS compliant in accordance with the applicable directives listed in product information.

Typical Applications

• General‑purpose power filtering — Low‑impedance behavior and defined ripple ratings make this capacitor suitable for smoothing and decoupling in compact power supplies and regulators.
• Compact electronic modules — Small radial can footprint and 2 mm lead spacing enable use in space‑constrained PCB assemblies and modules.
• High‑temperature environments — With a –55 °C to +105 °C range and 5000‑hour life at +105 °C, it is appropriate for designs requiring long‑term stability at elevated temperatures.
