UPW1V470MED

The UPW1V470MED is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UPW series, designed for high‑reliability power applications. It delivers 470 µF nominal capacitance at a 35 V rated voltage in a compact φ6.3 × 11 mm can with 2.5 mm lead spacing.

Engineered for demanding environments, the part combines a wide operating temperature range and specified ripple handling to support switching power supplies, DC–DC converters and other space‑constrained power circuits where endurance and stable filtering are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with tolerance of −20% to +20% at 20°C, rated for 35 V operation.
• Temperature Range — Specified to operate from −55°C to +105°C, enabling use across broad thermal conditions.
• Endurance — Rated for 2000 hours of operation at 105°C.
• Ripple Current Performance — Low‑frequency ripple current of 87 mA at 120 Hz and high‑frequency ripple current of 290 mA at 10 kHz, supporting filtering in switching applications.
• Loss and Leakage — Tangent of loss angle (tan δ) of 0.12 (measured at 20°C, 120 Hz) and specified leakage current of 49.35 µA.
• Package & Mounting — Radial lead can, axial dimensions φ6.3 × 11 mm, lead spacing 2.5 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Polarized Electrolytic — Polarized capacitor suitable for DC bias applications.
• AEC‑Q200 Qualification — Component-level AEC‑Q200 rating designated in the specifications for use in applications requiring automotive‑grade reliability testing.

Typical Applications

• Switching Power Supplies — Provides bulk and decoupling capacitance for regulation and output filtering in compact switch‑mode converters.
• DC–DC Converters — Supports stable output filtering and transient response in board‑level converter designs.
• Automotive Electronics — AEC‑Q200 listed and rated for −55°C to +105°C, suitable for electronic subsystems that require robust electrolytic capacitance.
• Power Backup and Hold‑up Circuits — Compact capacitance for short‑term hold‑up and local energy storage in constrained layouts.

Unique Advantages

• Compact form factor: 470 µF in a φ6.3 × 11 mm can minimizes board space while delivering significant capacitance.
• Designed for elevated temperatures: 2000 hours endurance at 105°C supports sustained operation in thermally demanding environments.
• Measurable ripple capability: Specified ripple currents at both low and high frequency (87 mA @120 Hz, 290 mA @10 kHz) give designers concrete limits for thermal and ripple budgeting.
• Low loss at rated conditions: tan δ of 0.12 at 20°C/120 Hz and a defined leakage current (49.35 µA) simplify circuit modeling for filtering and power integrity.
• Automotive‑grade qualification: AEC‑Q200 designation supports use where automotive reliability testing is required.
• Flexible packing options: Available in bulk (no terminal forming) or bag packing to match production handling and assembly needs.
