UPV1V390MGD

The UPV1V390MGD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPV series. It delivers a low-impedance solution in a compact radial-can package for general-purpose circuit designs.

This part is specified as 39 µF at 35 V with polarization and is designed for long-term operation up to +105°C (5000 hours load life). The component is RoHS compliant and suited to board-level applications that require compact electrolytic capacitance with defined ripple-handling capability.

Key Features

• Electrical Performance — Rated capacitance 39 µF at 35 V with a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Low Impedance / Ripple Handling — Designed for low impedance; rated ripple current values include 127.4 mA at 120 Hz and 245 mA at 200 kHz for the part.
• Thermal and Lifespan Stability — Specified operating temperature range from −55°C to +105°C and a 5000-hour load-life rating at +105°C.
• Reliability Metrics — Leakage current specification follows the series rule (≤ 0.03CV μA after 1 minute at 20°C); tan δ max for 35 V is 0.12 (measured at 120 Hz, 20°C) as published for the UPV series.
• Package and Mounting — Radial-lead, radial can package with 2.5 mm lead spacing for through-hole PCB assembly; polarized construction.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• General-purpose electronics — Suitable for circuit designs that require a compact, polarized aluminum electrolytic capacitor for general-purpose filtering and energy storage.
• PCB-mounted radial assemblies — Radial lead spacing and can-style package make this part appropriate for through-hole board layouts where a small footprint capacitor is needed.
• Industrial and commercial equipment — The −55°C to +105°C range and 5000-hour endurance at 105°C support use in equipment requiring sustained thermal performance.

Unique Advantages

• Long high-temperature endurance — 5000 hours at +105°C provides predictable lifetime behavior under elevated operating temperatures.
• Compact radial-can footprint — Small radial package with 2.5 mm lead spacing supports space-constrained through-hole designs.
• Measurable low-impedance characteristics — Published ripple current ratings at both low and high frequencies (127.4 mA at 120 Hz; 245 mA at 200 kHz) help designers match the part to system ripple requirements.
• Quantified loss and leakage — Series specifications include tan δ and a leakage-current limit (≤ 0.03CV μA after 1 minute at 20°C), enabling predictable AC and DC behavior.
• Regulatory conformity — RoHS compliance simplifies use in products that must meet current restricted-substance directives.

Why Choose UPV1V390MGD?
