UPM1K821MHD

The UPM1K821MHD is an aluminum electrolytic capacitor from Nichicon’s UPM series, offering 820 µF capacitance at an 80 V rating in a radial can package (φ18 × 35.5 mm). It is a polarized, low-impedance device designed for demanding applications that require sustained ripple handling and long operational life.

Targeted to automotive applications, the part combines AEC-Q200 qualification, RoHS compliance, and a 5000-hour load life at +105°C to deliver reliable performance across a wide temperature range.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance for bulk energy storage and decoupling.
• Low Impedance — Specified impedance of 49 mΩ to reduce voltage ripple under load.
• High Ripple Capability — Rated ripple currents of 1.375 A at 120 Hz and 1.91 A at 200 kHz to support both low- and high-frequency ripple conditions.
• Long Life / High Temperature Endurance — Rated for 5000 hours at +105°C under load, providing extended service life in elevated-temperature environments.
• Wide Temperature Range — Operates from −55°C to +105°C to handle significant thermal variation.
• Automotive-Grade Qualification — AEC-Q200 qualified and explicitly listed for automotive applications.
• Radial Lead, Can Package — Radial leaded construction with 7.5 mm lead spacing in a compact φ18 × 35.5 mm can (L: 3.55 × D: 1.8 cm) for through-hole assemblies.
• Leakage Current — Measured leakage current specification of 1968 µA for initial screening and design planning.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive systems — Designed for automotive electronics where AEC-Q200 qualification and long-term stability are required.
• Automotive power modules — Supports high ripple conditions with 1.375 A (120 Hz) and 1.91 A (200 kHz) ripple ratings.
• Automotive thermal environments — Rated for operation from −55°C to +105°C and a 5000-hour life at +105°C for thermal robustness.

Unique Advantages

• Proven high-temperature endurance: 5000 hours at +105°C provides measurable long-term reliability for designs exposed to elevated temperatures.
• Automotive qualification: AEC-Q200 rating supports use in automotive applications that require component-level qualification.
• High ripple tolerance: Dual ripple specifications (120 Hz and 200 kHz) allow designers to size the capacitor against both low- and high-frequency ripple demands.
• Low impedance: 49 mΩ impedance helps minimize voltage drop and improve decoupling effectiveness in power circuits.
• Compact radial package: φ18 × 35.5 mm can with 7.5 mm lead spacing enables straightforward through-hole mounting while conserving board area.
• Regulatory compliance: RoHS compliant for environmental and manufacturing compliance needs.
