UPJ1E680MED

The UPJ1E680MED is a Nichicon UPJ series aluminum electrolytic capacitor with a 68 µF capacitance and 25 V rated voltage in a radial-lead can. It leverages the UPJ series' low-impedance design intended for switching power supplies and general-purpose power filtering.

This compact radial component (φ6.3 × 11 mm) offers a wide operating temperature range from −55 °C to 105 °C and is RoHS compliant, making it suitable for a range of electronic designs that require reliable decoupling and bulk energy storage in through-hole assemblies.

Key Features

• Capacitance & Voltage — 68 µF capacitance with a 25 V rated voltage and capacitance tolerance of −20% to +20% for general-purpose filtering.
• Low-impedance UPJ series design — Part of Nichicon’s UPJ family, designed for lower impedance behavior appropriate for switching power supply applications.
• Thermal performance & endurance — Rated for operation from −55 °C to 105 °C with a specified life/endurance of 2000 hours at 105 °C.
• Ripple current capability — Low-frequency ripple current of 81.6 mA at 120 Hz and high-frequency ripple current of 160 mA at 200 kHz to support power-supply ripple handling.
• Loss characteristics — Dissipation factor (tan δ) of 0.14 measured at 20 °C, 120 Hz, 25 V, providing a defined loss profile for thermal and stability calculations.
• Leakage current — Specified leakage current of 51 µA, useful for bias and standby current budgeting.
• Package & mounting — Radial-lead can (φ6.3 × 11 mm) with 2.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for through-hole assembly.
• Regulatory compliance — RoHS compliant.

Typical Applications

• Switching power supplies — Low-impedance UPJ design and defined ripple current ratings support output filtering and decoupling in switch-mode power supplies.
• General power filtering — Bulk energy storage and smoothing in general-purpose electronic circuits requiring a 25 V rated electrolytic solution.
• Embedded and industrial electronics — Temperature range to 105 °C and radial through-hole mounting make it suitable for embedded boards and industrial control assemblies.

Unique Advantages

• Series-level low impedance: Leverages the UPJ series design intent for lower impedance behavior, aiding in improved ripple attenuation for switching supplies.
• Compact radial form factor: φ6.3 × 11 mm can and 2.5 mm lead spacing provide a small footprint for through-hole placement without sacrificing capacitance.
• Defined thermal and endurance specs: Rated for −55 °C to 105 °C with 2000 hours endurance at 105 °C, enabling predictable lifetime planning under elevated temperature stress.
• Frequency-aware ripple ratings: Separate low- and high-frequency ripple current specifications (81.6 mA at 120 Hz and 160 mA at 200 kHz) simplify selection for specific switching frequencies.
• Measured loss and leakage data: Provided tan δ (0.14 at 20 °C, 120 Hz) and leakage current (51 µA) let engineers accurately model dissipation and standby currents.
• RoHS compliant packaging options: Available in bulk or bag packing to match production handling and procurement preferences while meeting environmental requirements.
