UPJ1C681MPD

The UPJ1C681MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series designed for low-impedance, high-reliability power applications. With a rated capacitance of 680 µF at 16 V and a compact φ10 × 20 mm can, it is targeted at general-purpose power filtering and decoupling where long life and robust ripple handling are required.

Built for endurance, the UPJ series supports extended load life at elevated temperature (5,000 hours at 105°C for applicable case sizes) and is specified for a wide operating range from −55°C to +105°C, making it suitable for demanding electronic power systems including switching power supplies.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 16 V rated voltage and tolerance of −20% to +20% for stable bulk energy storage and decoupling.
• Low Impedance Design — UPJ series low-impedance construction supports efficient ripple attenuation and transient response in power circuits.
• Ripple Current Capability — Rated for 574.6 mA at 120 Hz (low frequency) and 845 mA at 200 kHz (high frequency), enabling sustained operation under AC ripple stress.
• Long Life / High Reliability — Endurance specified at 5,000 hours at 105°C for applicable case sizes, with capacitance change within ±20% and leakage current within specified limits after life test.
• Electrical Losses — Tangent of loss angle (tan δ) specified at 0.16 (measured at 20°C, 120 Hz), useful for assessing dissipation and AC performance.
• Compact Radial Can — Small form factor φ10 × 20 mm with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCB designs.
• Leakage Current — Product-level leakage current indicated as 326.4 µA, suitable for power supply and bulk capacitor roles where controlled leakage is required.
• Compliance & Packaging — RoHS-compliant; available in bulk (no terminal forming) or bag packing for production assembly workflows.

Typical Applications

• Switching Power Supplies — Low-impedance UPJ construction and rated ripple current make the UPJ1C681MPD suitable for output smoothing and bulk decoupling in switch-mode power supplies.
• DC-DC Converters — Compact φ10 × 20 mm sizing and high ripple capability support local energy storage and voltage stabilization in point-of-load converters.
• Industrial and Consumer Power Electronics — General-purpose filtering and decoupling in equipment that requires long operational life at elevated temperatures (−55°C to +105°C).

Unique Advantages

• Engineered for Low Impedance: UPJ series design reduces AC impedance for improved ripple attenuation and transient performance in power rails.
• High Ripple Handling: Specified ripple currents at both 120 Hz and 200 kHz provide quantifiable performance for designers managing both low- and high-frequency stress.
• Long Endurance at Elevated Temperature: 5,000-hour life at 105°C (for applicable sizes) supports designs requiring extended reliability in hot operating environments.
• Compact, Through-Hole Friendly Form Factor: φ10 × 20 mm can and 5 mm lead spacing provide a small footprint for radial-lead mounting while retaining significant capacitance.
• Clear Electrical Characterization: Specified tan δ, leakage current, and tolerance figures allow predictable selection and margining in power designs.
• Production-Ready Packaging: Available in bulk or bag packing to support prototyping and volume assembly processes.
