UPW2G3R3MPD

The UPW2G3R3MPD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon's UPW series, engineered for high‑reliability power applications. It is a polarized capacitor rated at 3.3 µF and 400 V, designed for compact switching power supplies and automotive electronics where long endurance and stable performance across temperature are required.

Key value drivers include a compact φ10 × 20 mm can, AEC‑Q200 qualification, low loss characteristics (tanδ measured at 20°C, 120 Hz), and specified ripple and leakage performance for power filtering and smoothing duties.

Key Features

• Capacitance & Voltage — 3.3 µF rated capacitance with a 400 V rated voltage, suitable for high‑voltage filtering and energy storage in compact designs.
• Low Loss / Performance — tanδ (DF) = 0.25 measured at 20°C, 120 Hz, providing predictable AC loss characteristics for power applications.
• Ripple Current Ratings — Low‑frequency ripple current 36 mA at 120 Hz and high‑frequency ripple current 57.6 mA at 10 kHz, supporting both mains‑frequency and switching noise suppression.
• Leakage Current — Specified leakage current of 152.8 µA for predictable standby and bias behavior.
• Temperature & Endurance — Operating range −40°C to 105°C with a rated life of 5000 hours at 105°C, engineered for sustained operation under elevated temperature conditions.
• Mechanical / Package — Radial lead can, size φ10 × 20 L, lead spacing 5 mm (±0.5 mm), supplied bulk or bag packed for manual or semi‑automated assembly.
• Quality / Qualification — AEC‑Q200 rated and offered as part of Nichicon’s UPW series focused on miniature, low‑impedance, high‑reliability components for power electronics.
• Capacitance Tolerance & Polarization — Tolerance −20% to +20%; polarized construction for correct orientation in DC circuits.

Typical Applications

• Switching Power Supplies — Compact smoothing and decoupling where low impedance and defined ripple handling are required.
• Automotive Electronics — Power filtering and energy storage in automotive control modules, leveraging AEC‑Q200 qualification and high‑temperature endurance.
• Compact Power Conversion — Local energy storage and noise suppression in space‑constrained DC‑DC converters and power modules.

Unique Advantages

• High Voltage Capability: 400 V rating enables use in higher‑voltage rails where compact capacitance is needed.
• Compact, Serviceable Package: φ10 × 20 mm radial can with 5 mm lead spacing fits tight PCB real estate and straightforward through‑hole mounting.
• Designed for Elevated Temperatures: Rated −40°C to 105°C and 5000 hours at 105°C for long‑term reliability in hot environments.
• AEC‑Q200 Qualification: Industry qualification that supports integration into automotive and similarly demanding applications.
• Predictable AC Behavior: Specified tanδ and ripple current values at defined frequencies provide engineers with measurable parameters for filter and decoupling design.
