UPW2E2R2MPD

The UPW2E2R2MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPW series, configured as a radial-lead, polarized device. It is optimized for low impedance and compact power applications, offering a 2.2 µF capacitance at a 250 V rating with a small φ8 × 11.5 mm can.

Designed for demanding environments, the part supports a wide operating temperature range and endurance at elevated temperature, making it suitable for switching power supplies and automotive electronics where space, ripple handling and long-term stability are required.

Key Features

• Capacitance & Tolerance — 2.2 µF nominal capacitance with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 250 V DC rating for applications requiring higher voltage headroom in a compact package.
• Low Loss (tan δ) — Dissipation factor (tanδ) of 0.15 measured at 20°C, 120 Hz, supporting efficient filtering and decoupling.
• Ripple Current Capability — Low-frequency ripple current 29 mA at 120 Hz and high-frequency ripple current 46.4 mA at 10 kHz for effective AC ripple smoothing.
• Leakage Current — Specified leakage current of 95 µA, suitable for stable bias behavior in power circuits.
• High-Temperature Endurance — Rated for 3000 hours at 105°C, providing long-term reliability in elevated-temperature environments.
• Package & Mounting — Radial lead can (φ8 × 11.5 mm) with 3.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• Automotive-Grade Rating — AEC-Q200 rating for designs requiring automotive-focused component reliability and qualification.

Typical Applications

• Switching Power Supplies — Low-impedance miniature can suited for output filtering and decoupling in compact switch-mode power supplies.
• Automotive Electronics — AEC-Q200 rating and 105°C endurance make this capacitor appropriate for automotive power and control modules.
• Compact Power Modules — Small φ8 × 11.5 mm footprint and radial-lead format enable use in tight-layout power conversion and regulation assemblies.

Unique Advantages

• Compact, high-voltage solution: 250 V rating in a φ8 × 11.5 mm can conserves board space while providing significant voltage capability.
