UPM1J821MHD6

The UPM1J821MHD6 is an aluminum electrolytic capacitor from Nichicon’s UPM series, designed as a radial-lead, can-type capacitor delivering 820 µF at 63 V. It combines a compact φ18 × 30.5 mm package with low impedance and extended high-temperature endurance for demanding electronic power circuits.

Targeted applications include automotive and other power-electronics environments that require high capacitance, reliable performance up to +105°C, and AEC‑Q200 qualification. The part is available in mass-production quantities and RoHS‑compliant.

Key Features

• Capacitance and Voltage: 820 µF rated capacitance at 63 V—suitable where substantial bulk energy storage or smoothing is required within the part’s rated voltage.
• Low Impedance: Rated impedance of 32 mΩ, reducing voltage ripple under load and supporting efficient power delivery.
• High-Temperature Endurance: 5000 hours at +105°C life rating for long-term reliability in elevated temperature environments.
• AEC‑Q200 Qualified: Listed rating for AEC‑Q200, aligning the part with automotive-grade component requirements as stated in the product data.
• Ripple Current Capability: 1.289 A at 120 Hz and 1.79 A at 200 kHz, enabling effective handling of AC ripple in power circuits.
• Leakage Current Specification: Leakage current of 1549.8 µA (per the product data calculation and datasheet leakage formula of 0.03 × C × V) after 1 minute at 20°C.
• Radial-Lead Can Package: φ18 × 30.5 mm body with 7.5 mm lead spacing and lead diameter 0.8 mm, suitable for radial through-hole mounting and conventional assembly methods.
• Temperature Range and Compliance: Operates from –55°C to +105°C and is RoHS‑compliant.
• Availability and Packaging: Mass-production status with bulk (no terminal forming) and bag packing options.

Typical Applications

• Automotive power systems: Provides bulk energy storage and smoothing in vehicle power electronics where AEC‑Q200 qualification and +105°C endurance are required.
• Power supply filtering: Used for bulk filtering and decoupling on 63 V rails that demand high capacitance and low impedance to control ripple.
• High-temperature electronics: Suitable for electronic modules that operate continuously at elevated ambient temperatures up to +105°C thanks to the 5000 h life rating.

Unique Advantages

• High-capacitance solution: 820 µF in a compact φ18 can provides significant charge storage without a large PCB footprint.
• Designed for elevated temperatures: 5000 hours at +105°C gives designers quantifiable endurance for long-term operation in hot environments.
• Measurable ripple handling: Specified ripple currents at both 120 Hz and 200 kHz support realistic thermal and electrical design trade-offs.
• Automotive-grade qualification: AEC‑Q200 listing aligns the component with automotive application requirements as provided in the product data.
• Low impedance for improved stability: 32 mΩ impedance helps lower voltage drop and heat generation under load.
• Production-ready packaging: Mass-production availability and standard bulk/bag packing simplify procurement and assembly planning.
