UPM1C821MHD6

The UPM1C821MHD6 is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPM series designed for low impedance and high reliability. With an 820 µF capacitance at a 16 V rating, it addresses demanding power decoupling and energy-storage needs in temperature-variable environments.

Engineered for automotive applications, this part combines high ripple-current capability, AEC‑Q200 qualification, and a 5,000-hour endurance at 105°C to support long-term operation in harsh conditions.

Key Features

• Electrical Performance — Capacitance & Voltage: 820 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance for bulk energy storage and smoothing.
• Low Impedance: Specified impedance of 60 mΩ supports lower AC voltage drop under ripple conditions.
• Loss Tangent (tan δ): tanδ = 0.16 (measured at 20°C, 120 Hz), indicating controlled dielectric loss for stable performance at the rated voltage and frequency.
• Ripple Current Capability: Low-frequency ripple current 648 mA (120 Hz) and high-frequency ripple current 900 mA (200 kHz) to handle dynamic current loads.
• Leakage Current: Specified leakage current of 393.6 µA, measured after rated voltage application, supporting predictable bias characteristics.
• High Endurance: Rated life of 5,000 hours at 105°C under DC bias plus rated ripple current for extended in-field reliability.
• Wide Temperature Range: Operates from −55°C to +105°C to withstand broad environmental conditions.
• Package & Mounting: Radial lead can (φ12.5 × 15 mm), lead spacing 5.0 mm, supplied in bulk (no terminal forming) or bag packing for straightforward assembly.
• Compliance & Qualification: AEC‑Q200 qualification and RoHS compliance as specified in the product data.

Typical Applications

• Automotive power modules — Bulk capacitance and high ripple-current ratings make this capacitor suitable for smoothing and energy buffering in automotive power electronics.
• Automotive electronic control units (ECUs) — Wide operating temperature range (−55°C to +105°C) and 5,000-hour endurance at 105°C support long-term stability in control electronics.
• Automotive auxiliary systems — Low impedance and controlled leakage current help maintain stable DC bus and auxiliary power rails under variable load.

Unique Advantages

• Designed for long life in high temperature environments: 5,000-hour load life at 105°C ensures component longevity under continuous high-temperature operation.
• AEC‑Q200 qualified: Explicit qualification supports deployment in automotive applications where AEC‑Q200 is required.
• High ripple-current handling: Defined low- and high-frequency ripple current ratings (648 mA at 120 Hz and 900 mA at 200 kHz) enable reliable performance with switching and pulsed loads.
• Compact radial-can form factor: φ12.5 × 15 mm size with 5 mm lead spacing provides substantial capacitance in a small footprint for space-constrained designs.
• Predictable electrical characteristics: Low impedance (60 mΩ), controlled tanδ (0.16), and specified leakage current (393.6 µA) allow straightforward design margining and simulation.
• RoHS compliant: Meets environmental directive requirements as listed in the product data.
