UPS1J681MHD

The UPS1J681MHD is a 680 µF, 63 V aluminum electrolytic capacitor in a miniature radial can designed for switching power supplies and general-purpose power filtering. It delivers low impedance and wide operating temperature capability to support reliable bulk decoupling in compact, through‑hole board designs.

Built to the Nichicon UPS series specification, this component combines compact dimensions and measurable ripple handling with long high‑temperature life and RoHS compliance for commercial and industrial power electronics.

Key Features

• Capacitance & Voltage: 680 µF rated capacitance at 63 V providing bulk energy storage for power rails and filtering duties.
• Low Impedance: 58 mOhm impedance to reduce voltage drop under load and improve ripple attenuation in switching environments.
• Ripple Current Performance: Rated ripple current of 923 mA at 120 Hz and 1.3 A at 10 kHz, enabling effective handling of both low‑ and high‑frequency ripple components.
• Temperature Range: Wide operating range from −55 °C to +105 °C to support demanding thermal environments.
• Endurance: 3000 hours at 105 °C under rated conditions, suitable for long‑life applications requiring sustained high‑temperature performance.
• Compact Radial Package: Radial lead, can‑style package with lead spacing of 7.5 mm and small footprint (L: 2.5 × D: 1.6 cm) for space‑constrained board layouts.
• Polarized, Through‑Hole Mounting: Polarized aluminum electrolytic with radial leads for straightforward through‑hole assembly and robust mechanical retention.
• Environmental Compliance: RoHS‑compliant to the 2011/65/EU and (EU)2015/863 directives.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output decoupling to minimize ripple and support transient load demands in DC‑DC converters and SMPS modules.
• General‑Purpose Power Filtering: Through‑hole board designs requiring reliable energy storage and ripple suppression across a wide temperature range.
• Power Modules and Power Management: Local energy reservoir for regulator stages and power distribution networks where low impedance and high ripple handling are required.

Unique Advantages

• Improved Ripple Handling: Low measured impedance (58 mOhm) combined with specified ripple current ratings reduces heating and improves voltage stability under load.
• Wide Operating Temperature: −55 °C to +105 °C range supports deployments across varied environmental conditions without derating for temperature extremes specified in the product data.
• Long High‑Temperature Life: 3000 hours at 105 °C endurance supports extended service life in thermally demanding applications.
• Space‑Efficient Radial Design: Compact can and radial lead configuration simplify placement in dense through‑hole assemblies while maintaining required capacitance.
• Standards Compliance: RoHS conformity provides assurance for regulatory and environmental requirements in commercial and industrial products.
