UPJ1V681MHD6

The UPJ1V681MHD6 is a high-reliability miniature aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized capacitor rated at 680 µF and 35 V, designed for applications that require low impedance and sustained performance under elevated temperature and ripple stress.

Engineered for use in switching power supplies and general-purpose power circuits, the part combines high ripple current capability, extended load life, and a compact through-hole package for robust, serviceable designs.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a rated voltage of 35 V, with a capacitance tolerance of -20% to +20%.
• Low Impedance / Loss — Tangent of loss angle (tan δ) of 0.12 measured at 20°C, 120 Hz, supporting efficient filtering in power circuits.
• High Ripple Current Handling — Low-frequency ripple current of 863.6 mA (120 Hz) and high-frequency ripple current of 1.27 A (200 kHz), enabling reliable smoothing in switching supplies.
• Long Endurance — Rated for 5000 hours at 105°C under specified load conditions, supporting long-term operation in elevated-temperature environments.
• Wide Operating Temperature — Specified temperature range from -55°C to +105°C for broad environmental tolerance.
• Through-Hole Radial Package — Can-style radial package with dimensions φ18 × 15 mm (diameter × length) and lead spacing 7.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Leakage Current — Specified leakage current of 714 µA (measured condition as provided for the part).
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple current capability make it suitable for output filtering and energy storage in switch-mode converters.
• Industrial Power Electronics — Long endurance at 105°C and wide temperature range support power rails and bulk filtering in industrial controllers and power modules.
• General-Purpose Electronic Equipment — Compact radial through-hole form factor and standard lead spacing facilitate easy replacement and prototyping in a variety of electronic systems.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 863.6 mA (120 Hz) and 1.27 A (200 kHz) allow effective smoothing across a broad frequency range.
• Extended high-temperature life: 5000-hour endurance rating at 105°C delivers predictable long-term performance in hot operating environments.
• Wide operating envelope: -55°C to +105°C temperature range provides resilience across demanding ambient conditions.
• Low dissipation factor: tan δ of 0.12 (35 V, 120 Hz, 20°C) helps minimize power loss in filtering applications.
• Compact, serviceable package: φ18 × 15 mm can with 7.5 mm lead spacing offers a space-efficient, through-hole mounting option for repairable designs.
• Regulatory compliance: RoHS compliant for environmentally conscious assemblies.
