UPW1H331MPD6

The UPW1H331MPD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPW series, offered in a radial-lead can for through-hole mounting. Designed for power electronics, it delivers low impedance and high ripple handling in a compact φ10 × 30.5 mm package.

Common use cases include switching power supplies and automotive power electronics where long endurance, wide temperature range, and robust ripple performance are required. Key value is provided by its combination of 330 µF capacitance, 50 V rating, low impedance, and AEC‑Q200 qualification.

Key Features

• Capacitance & Voltage — 330 µF capacitance with a 50 V rated voltage and capacitance tolerance of ±20% (–20%/+20%).
• Low Impedance — Rated impedance of 120 mΩ to support effective decoupling and filtering in power rails.
• High Ripple Current Capability — Handles 1.046 A at 120 Hz (low frequency) and 1.61 A at 10 kHz (high frequency), enabling reliable smoothing in switching environments.
• Loss Angle (tan δ) — tan δ = 0.10 (measured at 20°C, 120 Hz), indicating controlled dissipation for thermal and stability planning.
• Leakage Current — Specified leakage current of 495 µA for predictable standby or static power loss.
• High Endurance — Rated life of 5000 hours at 105°C for sustained high-temperature operation.
• Wide Temperature Range — Operating range from –55°C to +105°C for demanding thermal environments.
• Mechanical & Packaging — Radial lead construction with 5 mm lead spacing (±0.5 mm) in a φ10 × 30.5 mm can; available in bulk (no terminal forming) or bag packing. Product is in mass production.
• Automotive-Grade Reliability — AEC‑Q200 rated, suitable for automotive electronic applications.

Typical Applications

• Switching Power Supplies — Bulk decoupling and output smoothing where low impedance and high ripple handling improve regulator stability.
• Automotive Power Electronics — Power filtering and energy storage in control modules and power distribution thanks to AEC‑Q200 qualification and wide temperature tolerance.
• DC‑DC Converters — Input/output smoothing in compact converter designs that require high ripple current capability in a small footprint.
• Industrial Power Modules — Energy buffering and transient suppression in motor drives and power management modules operating across harsh temperatures.

Unique Advantages

• Compact, low-impedance form factor — φ10 × 30.5 mm can with 120 mΩ impedance provides strong filtering performance in space-constrained designs.
• Robust ripple performance — Specified ripple currents of 1.046 A (120 Hz) and 1.61 A (10 kHz) enable reliable smoothing across common switching frequencies.
• Designed for high-temperature endurance — 5000 hours at 105°C supports long-term operation in elevated ambient conditions.
• Automotive-capable qualification — AEC‑Q200 rating supports use in automotive electronic systems that require verified reliability.
• Through-hole radial lead package — 5 mm lead spacing and robust can construction simplify mounting and mechanical retention in board-level power designs.
• Predictable electrical behavior — Tightly specified tan δ (0.10 at 20°C/120 Hz) and leakage current (495 µA) aid thermal and power-loss budgeting.
