UPM1H181MHD6

The UPM1H181MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UPM series, offering 180 µF capacitance at a 50 V rating with ±20% tolerance. Designed as a low-impedance, high-reliability component, it targets automotive and other demanding applications where sustained performance, long life, and robustness across temperature extremes are required.

Key value propositions include low ESR and measurable ripple handling, compact radial can packaging (12.5 mm diameter × 15 mm length), and proven endurance (5000 hours at 105°C) backed by AEC-Q200 qualification and RoHS compliance.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance at 50 V with ±20% tolerance for predictable energy storage and filtering performance.
• Low Impedance — Specified impedance of 95 mΩ to support efficient smoothing and decoupling on power rails.
• Ripple Current Capability — Handles 326.7 mA at 120 Hz and 605 mA at 200 kHz, enabling reliable ripple dissipation across low- and high-frequency domains.
• High Reliability Endurance — Load-life rating of 5000 hours at 105°C, supporting long-term operation in elevated-temperature environments.
• Wide Temperature Range — Operating range from −55°C to +105°C for use across harsh thermal conditions.
• Radial Lead Package — Compact radial can (φ12.5 mm × 15 mm) with 5 mm lead spacing for through-hole mounting and secure mechanical attachment.
• Industry Qualification & Compliance — AEC-Q200 qualified and RoHS compliant for regulated and vehicle-grade designs.
• Polarized Design — Standard polarized aluminum electrolytic format for primary power filtering and bulk energy storage.

Typical Applications

• Automotive Power Supplies — Bulk filtering and smoothing on 12 V and 24 V systems where AEC-Q200 qualification and high-temperature endurance are required.
• In-vehicle Electronics — Power rail decoupling for control modules and accessory electronics benefiting from low impedance and ripple handling.
• Power Conversion & Conditioning — Energy storage and ripple suppression in DC–DC converters and regulator outputs exposed to wide temperature ranges.

Unique Advantages

• Measured Low ESR (95 mΩ) — Enables better transient response and reduced heat generation under ripple, improving system stability.
• High Ripple Endurance — Specified ripple current values at both 120 Hz and 200 kHz support performance across mains-frequency and switching-frequency disturbances.
• Long High‑Temperature Life — 5000-hour load life at 105°C provides predictable longevity for designs subjected to sustained elevated temperatures.
• Compact Through‑Hole Form Factor — φ12.5 mm × 15 mm radial can with 5 mm lead spacing balances board space and mechanical robustness for rugged assemblies.
• AEC‑Q200 Qualification & RoHS Compliance — Supports regulated and vehicle-grade programs while meeting environmental directives.
• Wide Operating Temperature — −55°C to +105°C rating allows deployment in harsh thermal environments without derating design intent.
