UPM1A820MDD

The UPM1A820MDD is a radial-leaded aluminum electrolytic capacitor from Nichicon's UPM series, offering a compact 82 µF capacitance at a 10 V rating. It is a polarized, low-impedance device designed for demanding operating conditions, with a wide operating temperature range and AEC‑Q200 qualification for automotive applications.

Engineered for power filtering and decoupling in space-constrained designs, this part delivers measurable performance metrics—tolerance, loss angle, leakage and ripple current—useful for engineers specifying capacitors for automotive and industrial electronics.

Key Features

• Capacitance & Voltage — 82 µF rated capacitance with a 10 V rated voltage, suitable for low-voltage power rail filtering and decoupling.
• Loss and Dissipation — tanδ (DF) of 0.19 measured at 20°C, 120 Hz, providing a quantified view of dissipation for AC ripple conditions.
• Leakage Current — Specified leakage current of 24.6 µA, enabling predictable standby and bias behavior in low-voltage circuits.
• Ripple Current Performance — Low-frequency ripple current of 57.2 mA at 120 Hz and high-frequency ripple current of 110 mA at 1 kHz, allowing designers to size for both mains-frequency and higher-frequency switching environments.
• Operating Temperature & Endurance — Rated for −55°C to 105°C with a listed endurance/life of 2000 hours at 105°C, matching thermal and lifetime targets for robust electronics.
• Package & Mounting — Radial lead (can) package, size φ5 × 11 mm (L: 1.1 × D: 0.5 cm) with 2 mm lead spacing (±0.5 mm), offered in bulk/bag packing for through-hole assembly and manual placement.
• Standards & Compliance — AEC‑Q200 qualified and RoHS compliant, aligning with automotive-oriented qualification and environmental requirements.
• Marking — Marked in white on a dark brown sleeve for clear polarity and part identification.

Typical Applications

• Automotive power modules — Local smoothing and decoupling on low-voltage control and sensor power rails, benefiting from AEC‑Q200 qualification and the −55°C to 105°C operating range.
• Embedded power supplies — Bulk and output filtering for compact, board-mounted supplies where a small radial electrolytic is required.
• Sensor and interface electronics — Stabilizing supply rails for sensors and signal-conditioning circuits that demand low leakage and predictable tanδ behavior.

Unique Advantages

• Measured dissipation (tanδ) provided — Enables engineers to evaluate AC loss directly for design margin and thermal planning.
• Dual-frequency ripple ratings — Specified ripple current at both 120 Hz and 1 kHz supports designers working with mains-frequency smoothing and switching regulator outputs.
• Compact radial can — φ5 × 11 mm package delivers required capacitance in a small footprint for constrained PCB layouts.
• AEC‑Q200 qualification — Clear indication that the part meets automotive-oriented qualification criteria, useful for vehicle-grade electronics designs.
• Wide temperature tolerance — −55°C to 105°C rating supports a broad range of environmental conditions common in automotive and industrial applications.
