UPM1V182MHD

The UPM1V182MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPM series, specified for high-reliability applications. It delivers 1.8 mF capacitance at a 35 V rated voltage with low impedance characteristics and is supplied in bulk (no terminal forming) / bag packing for mass production.

Designed for demanding environments, the device offers long-term endurance and documented performance over a wide operating temperature range, making it suitable for automotive and industrial power electronics where low ESR, ripple handling and durability are required.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) rated at 35 V for bulk energy storage and decoupling on mid-voltage rails.
• Low Impedance — Specified impedance of 22 mΩ to support low-loss power filtering and fast transient response.
• Ripple Current Capability — Handles 2.205 A at 120 Hz and 2.25 A at 200 kHz, supporting both low- and high-frequency ripple conditions.
• High Reliability Endurance — Lifetime specified at 5000 hours at +105°C, enabling sustained performance in elevated-temperature environments.
• Wide Temperature Range — Rated for operation from −55°C to +105°C for thermal robustness across harsh conditions.
• Radial Lead, Can Package — Through-hole radial lead mounting with 7.5 mm lead spacing and compact dimensions (L: 3.05 × D: 1.6 cm) for board-level integration.
• Polarity & Tolerance — Polarized electrolytic capacitor with capacitance tolerance of −20% to +20% for predictable design margins.
• Automotive Qualification & Compliance — AEC-Q200 rated and RoHS compliant, supporting automotive-grade design requirements and environmental regulations.
• Production Packaging — Supplied in bulk (no terminal forming) / bag packing to suit high-volume manufacturing flows.

Typical Applications

• Automotive power systems — Bulk energy smoothing, DC-link and decoupling on 35 V rails where AEC-Q200 qualification and high-temperature endurance are required.
• Motor control and power converters — Low impedance and high ripple current capability support inverter and converter DC-link filtering under dynamic loads.
• Industrial power electronics — Durable operation at −55°C to +105°C and 5000 h endurance at 105°C for long-term reliability in industrial environments.
• Backup and energy storage — Bulk capacitance for hold-up and transient energy buffering in systems with mid-voltage supplies.

Unique Advantages

• Measurable low ESR — 22 mΩ impedance provides quantifiable reduction in AC losses and improved transient response compared to higher-ESR options.
• Documented high-temperature life — 5000 hours at +105°C gives designers a clear endurance metric for thermal stress planning and reliability analyses.
• Dual-frequency ripple support — Specified ripple current values at both 120 Hz and 200 kHz enable designers to size components for mixed-frequency environments.
• AEC-Q200 qualification — Series-level automotive qualification supports use in vehicle systems and other applications demanding automotive-grade components.
• Production-ready packaging — Bulk/no-terminal-forming bag packing streamlines handling for high-volume assembly and reduces pre-assembly processing steps.
• Regulatory compliance — RoHS compliant for straightforward integration into designs subject to environmental legislation.
