UPW1H471MHD

The UPW1H471MHD from Nichicon is a miniature, high-reliability radial lead aluminum electrolytic capacitor in the UPW series. It provides 470 µF nominal capacitance at 50 V in a compact φ12.5×20 mm can with 5 mm lead spacing, designed for power electronics where low impedance and extended endurance are required.

Typical use cases include switching power supplies and automotive electronics that demand durable, high-ripple handling capacitors rated for long life at elevated temperature.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 50 V rated voltage and tolerance of −20% to +20%.
• Low Impedance — Rated impedance of 120 mΩ for improved transient performance in power rails and supply decoupling.
• High Ripple Current Capability — Handles 1.125 A at 120 Hz (low frequency) and 1.5 A at 10 kHz (high frequency) for demanding switching applications.
• Long Endurance at Elevated Temperature — Rated life of 7000 hours at 105 °C, supporting sustained operation in high-temperature environments.
• Wide Operating Temperature — Specified for −55 °C to +105 °C operation.
• Electrical Loss (tan δ) — tanδ of 0.10 measured at 20 °C, 120 Hz, supporting predictable loss characteristics in design.
• Compact Radial Package — φ12.5×20 mm can, radial lead mounting, lead spacing 5 mm (±0.5 mm); available in bulk or bag packing.
• AEC‑Q200 Rated — Series includes AEC‑Q200 rating, aligning the part for automotive-grade reliability requirements.

Typical Applications

• Switching Power Supplies — Miniature, low-impedance construction supports bulk filtering and decoupling in switched-mode power designs.
• Automotive Electronics — AEC‑Q200 rating and long endurance at 105 °C make the part suitable for automotive control modules and power subsystems.
• High‑Temperature Power Systems — 7000 hour life at 105 °C supports use in electronics exposed to sustained elevated temperatures.

Unique Advantages

• High ripple tolerance: 1.125 A (120 Hz) and 1.5 A (10 kHz) ripple current ratings reduce heating and improve reliability in switching environments.
• Extended high‑temperature lifetime: 7000 hours at 105 °C provides predictable aging and service life for thermal-stressed applications.
• Compact footprint: φ12.5×20 mm can with 5 mm lead spacing delivers substantial capacitance in a small radial package for space‑constrained boards.
• Low impedance (120 mΩ): Supports fast transient response and stable power rail performance under load.
• Automotive‑grade reliability: AEC‑Q200 rating addresses qualification expectations for automotive and similarly demanding applications.
• Clear electrical characterization: Specified tanδ (0.10 at 20 °C, 120 Hz) and a defined leakage current value support accurate design margining.
