UPW0J821MPD6

The UPW0J821MPD6 is an aluminum electrolytic capacitor in a radial can package designed for compact power applications. It delivers 820 μF at 6.3 V with low impedance and rated ripple performance, making it suitable for switching power supplies and other board-level power filtering needs.

Built for reliability, this radial-lead device is specified for operation from −55°C to 105°C and carries AEC-Q200 ratings for automotive-capable designs, with a demonstrated lifetime of 5000 hours at 105°C.

Key Features

• Capacitance & Voltage — 820 μF capacitance at a 6.3 V rated voltage with ±20% tolerance (measured at 120 Hz, 20°C).
• Low Impedance — Rated impedance of 180 mOhm to support low-loss smoothing and decoupling in power rails.
• High Ripple Handling — Ripple current ratings of 566.3 mA at 120 Hz and 755 mA at 10 kHz enable effective filtering across frequency ranges common in switching supplies.
• Automotive-Grade Reliability — AEC-Q200 rating and a 5000-hour endurance at 105°C provide a qualification baseline for vehicle-level power systems.
• Wide Temperature Range — Operates from −55°C to 105°C for use in demanding thermal environments.
• Radial Lead, Compact Can — Radial-lead mounting with 5 mm lead spacing and compact dimensions (L: 1.25 × D: 1 cm) for tight PCB layouts.
• Polarized Construction — Polarized aluminum electrolytic design suitable for standard DC power applications.

Typical Applications

• DC-DC Converters — Local output smoothing and bulk decoupling in switching regulators where low impedance and compact size are required.
• On-board Power Filtering — Bulk storage and ripple attenuation on power rails for embedded systems and industrial electronics.
• Automotive Electronics — Power modules and control units where AEC-Q200 qualification and high-temperature endurance are important.
• Power Supply Modules — Input and output filtering in board-mounted switching power supplies for consumer and industrial equipment.

Unique Advantages

• Compact footprint: The L: 1.25 × D: 1 cm can and 5 mm lead spacing enable dense PCB placement without sacrificing capacitance.
• Designed for low-loss power delivery: 180 mOhm impedance and high ripple current ratings reduce voltage ripple and thermal stress on power stages.
• High-temperature endurance: 5000 hours at 105°C supports long-term reliability in elevated-temperature applications.
• Automotive-capable: AEC-Q200 rating helps streamline use in vehicle electronics that require graded component qualification.
• Robust operating range: −55°C to 105°C temperature rating allows deployment across harsh environmental conditions.
