UPS0J681MPD

The UPS0J681MPD is a miniature aluminum electrolytic capacitor designed for switching power supplies and general-purpose power filtering. It is a polarized, radial-lead can that delivers 680 µF at a rated voltage of 6.3 V.

Engineered for compact power designs, this part combines low impedance (190 mΩ) with a wide operating temperature range (−55 °C to +105 °C) and defined ripple-current capabilities to support stable DC rail smoothing and decoupling in space-constrained assemblies.

Key Features

• Core Electrical: 680 µF capacitance at 6.3 V rating, with a tolerance of ±20% (−20% ~ 20%).
• Low Impedance Performance: Rated impedance of 190 mΩ for reduced voltage ripple and improved transient response in power rails.
• Ripple Current Capability: Specified ripple current of 426 mA at 120 Hz and 600 mA at 10 kHz, supporting common switching frequencies and higher-frequency decoupling.
• Thermal and Reliability: Wide operating temperature range from −55 °C to +105 °C and endurance rated for 2000 hours at 105 °C.
• Package & Mounting: Radial lead, can-style package with 5 mm lead spacing and compact dimensions (L: 1.25 cm × D: 1.0 cm) for through-hole assemblies.
• Environmental Compliance: Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies: Bulk smoothing and output decoupling to reduce voltage ripple and stabilize regulator outputs.
• DC-DC Converters: Input and output filtering where compact size and ripple handling are required.
• General-Purpose Power Filtering: Through-hole assemblies in consumer and industrial equipment that require robust temperature performance and reliable capacitance.

Unique Advantages

• Compact footprint with high capacitance: 680 µF in a 1.25 cm × 1.0 cm can enables higher bulk capacitance in tight board space.
• Low impedance for improved transient response: 190 mΩ impedance helps reduce AC ripple and supports fast load changes on power rails.
• Rated ripple-handling at multiple frequencies: Specified ripple currents of 426 mA (120 Hz) and 600 mA (10 kHz) allow confident selection for both line-frequency smoothing and higher-frequency decoupling.
• Wide temperature capability and proven endurance: −55 °C to +105 °C operating range and 2000 hours at 105 °C support reliable operation in demanding thermal environments.
• Through-hole radial-lead format: Simple integration into existing through-hole layouts with 5 mm lead spacing for mechanical stability and ease of assembly.
• RoHS compliant: Meets current RoHS directives for environmentally regulated designs.
