UPM1A681MPD

The UPM1A681MPD is a radial-lead aluminum electrolytic capacitor offering 680 µF capacitance at a 10 V rating in a compact φ8 × 20 mm can. Designed for demanding environments, it combines low impedance and defined ripple-current capability to support reliable power conditioning in automotive electronics and related systems.

With AEC‑Q200 qualification, a wide operating temperature range and a rated life at elevated temperature, this part addresses applications that require stable capacitance, controlled loss (tanδ), and durable operation under ripple and thermal stress.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a rated voltage of 10 V with ±20% tolerance (120 Hz, 20 °C).
• Low Loss — tanδ specified at 0.19 (max) for the 10 V rating, supporting lower dissipation in AC conditions.
• Low Impedance — rated impedance of 85 mΩ to support effective decoupling and energy storage in compact spaces.
• Ripple Current Capability — 448.8 mA at 120 Hz and 660 mA at 200 kHz, enabling handling of both low- and high-frequency ripple in power circuits.
• Robust Temperature & Lifetime — operating range from −55 °C to +105 °C and rated for 3000 hours at 105 °C for long-term stability under elevated temperature stress.
• Package & Mounting — radial-lead, can-type package (φ8 × 20L) with 3.5 mm lead spacing and standard lead diameters for ease of through-hole assembly; supplied in bulk/no terminal forming for mass production.
• Leakage Current — specified leakage current of 204 µA after rated voltage application, suitable for power management designs requiring defined standby characteristics.
• Automotive-Grade Qualification — AEC‑Q200 rating and RoHS compliance for designs targeting regulated automotive environments.

Typical Applications

• Automotive electronics — Energy storage and smoothing in vehicle electronic modules where AEC‑Q200 qualification and wide temperature range are required.
• On-board power buffering — Local bulk capacitance for voltage stabilization in 10 V systems, leveraging 680 µF capacity and low impedance.
• Ripple filtering — Handling of specified ripple currents at 120 Hz and 200 kHz for power-supply ripple suppression across frequency ranges.

Unique Advantages

• AEC‑Q200 Qualified: Provides the qualification level expected for automotive electronic components, supporting deployment in regulated vehicle systems.
• Compact, High-Capacity Form Factor: 680 µF in a φ8 × 20 mm radial can allows designers to save board space while retaining substantial bulk capacitance.
• Measured Low Impedance and Controlled Loss: 85 mΩ impedance and tanδ 0.19 help reduce voltage ripple and thermal dissipation in power circuits.
• Defined Ripple Performance: Separate ripple-current ratings at 120 Hz and 200 kHz give clear guidance for low- and high-frequency filtering design margins.
• Wide Temperature Range and Rated Life: −55 °C to +105 °C operation with 3000 hours at 105 °C supports designs requiring long-term stability under thermal stress.
• Manufacturing-Friendly Supply: Supplied bulk/no terminal forming for mass production yields straightforward through-hole assembly workflows.
