UPW1C681MPD

The UPW1C681MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPW series. It is a radial-lead, polarized device providing 680 µF capacitance at a 16 V rating in a compact φ10 × 16 mm can.

Designed for power smoothing and decoupling in demanding environments, the part combines low impedance (136 mΩ), robust ripple-current capability, an extended operating range of −55°C to 105°C, and a rated life of 5000 hours at 105°C. The device carries an AEC‑Q200 rating for automotive-grade reliability and is available in bulk or bag packing for production usage.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance with a rated voltage of 16 V and a capacitance tolerance of −20% to +20%.
• Low Impedance — Impedance specified at 136 mΩ, supporting improved transient response in power rails and switching supplies.
• Ripple Current Handling — Low-frequency ripple current 787.5 mA (120 Hz) and high-frequency ripple current 1.05 A (10 kHz), enabling reliable filtering under dynamic loads.
• Loss Characteristics — tan δ of 0.16 (measured at 20°C, 120 Hz) for predictable dissipation behavior.
• Leakage Current — Specified leakage current of 326.4 µA after rated voltage application, useful for power-budgeting and standby calculations.
• Thermal and Endurance — Operating temperature range −55°C to 105°C with endurance rated to 5000 hours at 105°C.
• Package and Mounting — Radial lead (φ10 × 16 mm body), 5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing; mass-production status.
• Automotive Qualification — AEC‑Q200 rated for designs requiring automotive-grade component qualification.

Typical Applications

• Switching Power Supplies — Output smoothing and bulk energy storage in compact DC–DC converters and SMPS modules.
• Automotive Electronics — Power rail decoupling and filtering in automotive control modules where AEC‑Q200 qualification is required.
• Industrial Power Modules — Local energy buffering and ripple suppression in motor drives, control power supplies, and industrial converters.
• Embedded Systems — Bulk capacitance and transient support for compact, board-level power subsystems.

Unique Advantages

• Compact high-capacitance solution: 680 µF in a φ10 × 16 mm can reduces board footprint while providing substantial charge storage.
• High ripple capability across frequencies: Specified ripple currents at 120 Hz and 10 kHz (787.5 mA and 1.05 A) support both low- and high-frequency switching environments.
• Engineered for harsh environments: −55°C to 105°C operation and 5000 hours endurance at 105°C address long-term reliability in elevated-temperature applications.
• Measurable electrical performance: Low impedance (136 mΩ), defined tan δ (0.16), and quantified leakage current (326.4 µA) allow designers to model power loss and stability accurately.
• Automotive-grade qualification: AEC‑Q200 rating facilitates use in designs targeting automotive electronics and related reliability requirements.
• Production-ready packaging: Available in bulk or bag packing and in mass-production status to support volume manufacturing needs.
