UPM1A821MPD

The UPM1A821MPD is a radial-lead aluminum electrolytic capacitor offering 820 µF capacitance at a 10 V rating. It delivers low impedance and measurable ripple-current capability in a compact φ10 × 20 mm can, designed for applications that require sustained performance across a wide temperature range.

Built for demanding operating conditions, this part provides long endurance at elevated temperature and is AEC‑Q200 qualified and RoHS compliant, making it suitable for rugged electronics where reliability and lifecycle are key considerations.

Key Features

• Electrical Performance — 820 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C, and a rated voltage of 10 V.
• Low Impedance — Specified impedance of 70 mΩ to support stable performance under dynamic load conditions.
• Ripple-Current Capability — Low-frequency ripple current of 601.2 mA at 120 Hz and high-frequency ripple current of 835 mA at 200 kHz, enabling effective smoothing and decoupling in power circuits.
• Loss Characteristics — tanδ of 0.19 measured at 20 °C, 120 Hz, for predictable dissipation behavior in AC conditions.
• Leakage — Specified leakage current of 246 µA for controlled standby behavior after voltage application.
• Reliability and Endurance — Rated for 5000 hours at 105 °C (endurance), supporting designs that require long-term stability at elevated temperatures.
• Mechanical Package — Radial lead can, size φ10 × 20 mm with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing (no terminal forming).
• Compliance and Qualification — AEC‑Q200 qualified and RoHS compliant for regulated and automotive-focused designs.

Typical Applications

• Automotive Electronic Modules — Filtering and energy storage on DC power rails for control units where AEC‑Q200 qualification and high-temperature endurance are required.
• Power Supply Filtering — Smoothing and decoupling in DC‑DC converters or intermediate rails, taking advantage of specified ripple-current ratings and low impedance.
• High-Temperature Environments — Electronic subsystems operating up to 105 °C where long life and stable capacitance are needed over time.

Unique Advantages

• Long Endurance at Elevated Temperature: 5000 hours rated life at 105 °C supports durable designs and reduces maintenance cycles.
• Measured Ripple Performance: Explicit low- and high-frequency ripple current specifications (601.2 mA at 120 Hz, 835 mA at 200 kHz) let engineers size capacitors against real ripple loads.
• Compact Radial Form Factor: φ10 × 20 mm can with 5 mm lead spacing provides a space-efficient option for through‑hole assembly and prototyping.
• Low Impedance: 70 mΩ impedance improves transient response and reduces voltage drop under load.
• Automotive-Grade Qualification: AEC‑Q200 qualification and RoHS compliance support use in regulated automotive electronics designs.
