UPM1H471MHD

The UPM1H471MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, specified at 470 µF and 50 V. It combines low impedance and robust ripple-handling with a high-reliability construction suited for demanding electronic environments.

Designed and qualified for high-temperature endurance and AEC‑Q200 requirements, this part targets applications where long life, stable filtering and automotive-grade qualification are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, providing bulk energy storage for a wide range of power circuits.
• Low Impedance — 44 mΩ impedance supports low-loss performance in smoothing and decoupling roles.
• High Ripple Capability — Low-frequency ripple current 744 mA (120 Hz) and high-frequency ripple current 1.2 A (200 kHz) for reliable operation under continuous AC stress.
• High-Temperature Endurance — Rated for 5000 hours at 105°C, enabling long operational life in elevated-temperature installations.
• Loss Characteristics — tanδ = 0.10 measured at 20°C, 120 Hz, for predictable dissipation behavior.
• Leakage Current — Specified leakage current of 705 µA for predictable standby and bias conditions.
• Mechanical & Mounting — φ12.5 × 25L can with radial leads, 5 mm lead spacing (±0.5 mm), suitable for through-hole assemblies and hand or automated insertion.
• Automotive Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant, supporting regulated industry requirements.
• Packaging & Availability — Available in bulk (no terminal forming) and bag packing; status: mass production.

Typical Applications

• Automotive electronic modules — AEC‑Q200 qualification and 5000 h life at 105°C make this capacitor suitable for automotive ECUs and control modules requiring long-term reliability.
• Power conditioning — Low impedance (44 mΩ) and rated ripple currents (744 mA @120 Hz, 1.2 A @200 kHz) provide effective smoothing and filtering in power supplies and converters.
• High-temperature electronics — Specified operating range of −55°C to 105°C and high-temperature endurance support applications exposed to elevated ambient conditions.

Unique Advantages

• Long-term stability under load: 5000 hours endurance at 105°C ensures sustained capacitance and leakage performance in high-temperature deployments.
• Reliable ripple handling: Defined low- and high-frequency ripple ratings support both mains-frequency smoothing and high-frequency converter filtering.
• Compact radial package: φ12.5 × 25L can with 5 mm lead spacing offers a space-efficient through-hole solution for board-level power designs.
• Automotive-grade qualification: AEC‑Q200 status aligns the component with automotive reliability expectations where qualification is required.
• Predictable electrical loss: tanδ = 0.10 at 20°C / 120 Hz provides clear characterization of dielectric losses for thermal and efficiency planning.
• Supply readiness: Mass production status and standard bulk/bag packing options simplify procurement and assembly planning.
