UPM2A181MHD6

The UPM2A181MHD6 is an aluminum electrolytic capacitor from Nichicon's UPM series designed for high-voltage, high-reliability applications. It is a radial-lead, polarized can-type capacitor with a 180 µF capacitance and a 100 V rated voltage.

Targeted for demanding environments, the device combines low impedance and elevated ripple-current capability with a wide operating temperature range and long load-life performance, making it suitable for automotive and other high-reliability systems.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Impedance — Specified impedance of 110 mΩ, supporting improved smoothing and reduced ripple voltage under load.
• High Ripple Current — Rated ripple current of 475.2 mA at 120 Hz and 880 mA at 200 kHz to handle high-frequency and low-frequency ripple in power circuits.
• Long Life & Temperature Endurance — Load life specified at 5000 hours at 105°C; operating temperature range from −55°C to +105°C.
• Automotive Qualification — AEC-Q200 rated and specified for automotive applications, supporting use in environments requiring automotive-level qualification.
• Radial Can Package — φ16 × 20 mm can with 7.5 mm lead spacing and radial lead mounting for through-hole assembly and robust mechanical retention.
• Leakage & Polarization — Polarized capacitor with an initial leakage current value of 540 µA (per product specification).
• RoHS Compliant — Conforms to RoHS requirements as indicated in the product data.

Typical Applications

• Automotive Power Electronics — Bulk energy storage and smoothing on DC-DC converter outputs and power rails where the 100 V rating and 880 mA high-frequency ripple capability reduce voltage ripple and heat.
• In-vehicle Power Supplies — Local energy reservoir for onboard power modules operating across −55°C to +105°C and requiring long-term stability (5000 h at 105°C).
• Motor Drive & Control Modules — Decoupling and filtering in motor controllers and inverter front-ends that demand high ripple endurance and low impedance.

Unique Advantages

• High-voltage capability: 100 V rating enables use on higher-voltage rails without series stacking.
• Reduced system ripple: Low impedance (110 mΩ) and high ripple-current ratings minimize ripple voltage and thermal stress in power stages.
• Designed for elevated temperatures: 5000-hour load life at 105°C provides predictable long-term performance in hot environments.
• Automotive-ready qualification: AEC-Q200 rating supports adoption in automotive designs requiring qualified components.
• Robust through-hole package: Radial can (φ16×20 mm) with 7.5 mm lead spacing offers mechanical durability and straightforward assembly for repairable or ruggedized designs.
• Standards compliance: RoHS compliance ensures alignment with common environmental requirements.
