UPM0J681MPD

The UPM0J681MPD from Nichicon is a radial-lead aluminum electrolytic capacitor offering 680 µF capacitance at a 6.3 V rating. It is a polarized, low-impedance device engineered for high-reliability applications, with AEC-Q200 qualification and RoHS compliance.

Designed for demanding environments, the part provides long-term stability with a 3,000 hour endurance at 105°C and an operating range from −55°C to +105°C. Its combination of high capacitance, rated ripple current, and compact φ8×20 mm can makes it suitable where robust power decoupling and energy buffering are required.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a 6.3 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Impedance: Rated impedance of 100 mΩ, helping reduce voltage ripple and improve transient response in power rails.
• Loss Angle (tan δ): tan δ of 0.22 at 20°C and 120 Hz, providing defined dissipation characteristics for design and stability calculations.
• Leakage Current: Specified leakage current of 128.52 µA after 1 minute at 20°C, enabling predictable standby and quiescent behavior.
• High Temperature Endurance: 3,000 hours rated life at 105°C, supporting long-term reliability in elevated-temperature environments.
• Ripple Current Capability: 411.4 mA at 120 Hz (low frequency) and 605 mA at 200 kHz (high frequency) to handle real-world AC ripple and switching noise.
• Package & Mounting: Radial lead can (φ8×20 mm) with lead spacing 3.5 mm (±0.5 mm) for through-hole mounting and straightforward PCB placement.
• Standards & Compliance: AEC-Q200 qualified and RoHS compliant for regulated markets and reliability-focused designs.
• Availability & Packaging: Mass production status with bulk/bag packing (no terminal forming), simplifying procurement and high-volume assembly.

Typical Applications

• Automotive Electronics: Power rail smoothing and decoupling in automotive modules where AEC-Q200 qualification and 105°C endurance are required.
• Power Supply Filtering: Bulk energy storage and ripple suppression on low-voltage DC rails, leveraging 680 µF capacitance and low impedance.
• Embedded Systems: Local decoupling for microcontroller and analog sections to stabilize supply during transient loads.

Unique Advantages

• Engineered for Heat Endurance: 3,000 hour life at 105°C provides predictable long-term performance in high-temperature assemblies.
• Automotive-Grade Qualification: AEC-Q200 rating supports use in reliability-sensitive applications and helps simplify supplier qualification.
• Compact, High-Capacity Form Factor: 680 µF in a φ8×20 mm can balances capacitance density with a small PCB footprint for space-constrained designs.
• Defined Ripple Handling: Specified ripple current at both low and high frequencies (120 Hz and 200 kHz) allows designers to size components against expected operating conditions.
• Predictable Leakage and Loss Characteristics: Published leakage current and tan δ values enable accurate power-budgeting and thermal calculations.
• Production-Ready Packaging: Mass production availability with bulk/bag packing eases volume purchasing and assembly planning.
