UPM1H681MHD6

The UPM1H681MHD6 is an aluminum electrolytic capacitor from Nichicon's UPM series, offered in a radial lead can with a φ16×20L package. It delivers 680 µF capacitance at a 50 V rating with low impedance and specifications aimed at high-reliability applications.

Designed for demanding environments, the part combines a wide operating temperature range (−55 °C to 105 °C), long endurance, and industry-recognized qualification to support automotive and other high-reliability power designs.

Key Features

• Capacitance & Voltage — 680 µF capacitance rated at 50 V with a tolerance of ±20% (measured at 120 Hz, 20 °C).
• Low Impedance and Loss — Rated impedance of 40 mΩ and a tangent of loss angle (tan δ) of 0.10 (measured at 120 Hz, 20 °C), supporting stable performance under ripple conditions.
• Ripple Current Handling — Supports 918 mA ripple at 120 Hz and 1.35 A at 200 kHz, enabling effective smoothing in power circuits across a range of frequencies.
• High Temperature Endurance — Life rating of 5000 hours at +105 °C, supporting sustained operation in elevated-temperature environments.
• Robust Packaging & Mounting — Radial lead can with 7.5 mm lead spacing and φ16×20L size (approx. 2.0 × 1.6 cm), supplied in bulk (no terminal forming) or bag packing.
• Leakage & Polarization — Polarized electrolytic design with specified leakage current of 1020 µA; intended for polarized power applications.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant, aligning with industry requirements for reliability and environmental regulations.

Typical Applications

• Automotive electronic control units (ECUs) — Bulk capacitance and ripple handling for power rails in control modules operating up to 105 °C and meeting AEC‑Q200 requirements.
• Automotive power distribution modules — Smoothing and decoupling in voltage regulation stages where long life and low impedance are required.
• Infotainment and lighting electronics — Energy storage and ripple suppression in systems that require stable performance across temperature extremes.

Unique Advantages

• High capacitance at 50 V — 680 µF enables significant bulk energy storage and smoothing while supporting medium-voltage architectures.
• Low ESR/Impedance — 40 mΩ impedance and tan δ of 0.10 improve transient response and reduce heat generation under ripple load.
• Proven thermal endurance — 5000‑hour life at 105 °C provides predictable aging characteristics for long-term designs.
• Frequency-flexible ripple performance — Specified ripple currents at both 120 Hz and 200 kHz suit low- and high-frequency power stages.
• Automotive-grade qualification — AEC‑Q200 qualification clarifies suitability for automotive electronic designs that require standardized reliability testing.
• Regulatory compliance — RoHS compliance supports use in designs targeting regional environmental regulations.
