UPM1V821MHD

The UPM1V821MHD is an aluminum electrolytic capacitor from Nichicon’s UPM series designed for low-impedance, high-reliability power applications. This radial-lead, polarized capacitor provides 820 µF capacitance at a 35 V rating and is available in a φ12.5 × 25 mm can with 5 mm lead spacing.

Engineered for sustained performance, the part features low impedance (32 mΩ), high ripple-handling capability and long endurance (5,000 hours at 105°C). It is suitable for automotive and industrial power electronics where temperature endurance, ripple tolerance and long-term reliability are required.

Key Features

• Capacitance & Voltage: 820 µF rated capacitance at 35 V for bulk energy storage and decoupling.
• Low Impedance: 32 mΩ impedance reduces voltage drop under transient and ripple conditions.
• High Ripple Handling: Low-frequency ripple current 1.073 A (120 Hz) and high-frequency ripple current 1.49 A (200 kHz) for robust filtering in power stages.
• Endurance: 5,000 hours rated life at 105°C when used within specified conditions, supporting long-term thermal stress tolerance.
• Temperature Range: −55°C to +105°C operating range for extended environmental compatibility.
• Leakage & Dissipation: Leakage current specified at 861 µA and tangent of loss angle (tan δ) 0.12 (measured at 20°C, 120 Hz) for predictable loss characteristics.
• Package & Mounting: Radial lead can (φ12.5 × 25 mm) with 5 mm lead spacing; available in bulk or bag packing for production and prototyping.
• Qualification & Compliance: AEC-Q200 rated and RoHS compliant, addressing regulated and automotive environments.

Typical Applications

• Automotive power electronics: Bulk smoothing and decoupling in in-vehicle power modules and electronic control units where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC converters and power supplies: Input/output filtering and energy storage for converter stages benefiting from low impedance and high ripple current capability.
• Motor drives and inverter support: Local energy buffering and ripple suppression in drive electronics exposed to elevated temperatures and continuous ripple stress.
• Industrial power systems: Filtering and hold-up in industrial controllers and power conditioning equipment that demand long life at 105°C.

Unique Advantages

• High-temperature endurance: 5,000-hour life at 105°C provides predictable ageing and extended service life in hot environments.
• Strong ripple tolerance: Specified ripple currents at both low (120 Hz) and high (200 kHz) frequencies support mixed-frequency power systems.
• Low ESR/impedance: 32 mΩ impedance helps minimize losses and voltage drop in high-current paths.
• Automotive-grade qualification: AEC-Q200 rating aligns the part with automotive system requirements and reliability expectations.
• Compact through-hole form factor: φ12.5 × 25 mm radial can with 5 mm lead spacing offers a straightforward through-hole mounting option for modules and boards.
• Production-ready supply: Mass production status with bulk and bag packing options for flexible procurement and assembly workflows.
