UPA0J681MPD

The UPA0J681MPD is a radial lead aluminum electrolytic capacitor from Nichicon’s UPA series, offering 680 µF capacitance at a 6.3 V rating. It combines a miniature φ8 × 11.5 mm can with low impedance and elevated ripple-current capability for compact power circuits.

Designed for general-purpose power filtering and switching power supply applications, this part provides long endurance at high operating temperatures and RoHS compliance for modern electronic designs.

Key Features

• Electrical Performance: 680 µF capacitance with ±20% tolerance and a rated voltage of 6.3 V; impedance specified at 180 mΩ and tanδ 0.22 (120 Hz, 20°C) for predictable AC behavior.
• High Ripple Capability: Low-frequency ripple current 472.5 mA (120 Hz) and high-frequency ripple current 630 mA (10 kHz) to support filtering in switching regulators and DC‑DC converters.
• Thermal and Lifetime Reliability: Rated for operation from −55°C to +105°C with a guaranteed endurance of 3000 hours at 105°C under specified conditions.
• Compact Radial Package: φ8 × 11.5 mm can with radial lead mounting, 3.5 mm lead spacing (±0.5 mm tolerance) for space-efficient through-hole designs.
• Leakage and Loss Characteristics: Leakage current specified at 128.52 µA and low loss tangent (tanδ) to maintain stable performance in bias and ripple conditions.
• Compliance & Availability: RoHS compliant and available in bulk or bag packing; part is in mass production.

Typical Applications

• Switching Power Supplies: Bulk and output smoothing where compact size and high ripple current handling are required.
• DC‑DC Converters and Power Modules: Local energy storage and decoupling for small footprint regulator circuits.
• Consumer and Industrial Electronics: General-purpose power filtering in compact boards and assemblies operating across a wide temperature range.

Unique Advantages

• Small footprint, high capacity: 680 µF in a φ8 × 11.5 mm can enables higher capacitance in space-constrained designs.
• High ripple tolerance for its size: Combined low-frequency and high-frequency ripple ratings support reliable filtering in switching environments.
• Wide temperature range with proven endurance: −55°C to +105°C rating and 3000 hours at 105°C provide predictable lifetime in demanding thermal conditions.
• Low impedance and controlled losses: 180 mΩ impedance and tanδ of 0.22 (120 Hz, 20°C) help minimize voltage ripple and heating under AC stress.
• Through‑hole radial convenience: Radial lead form and standard 3.5 mm lead spacing ease mounting and prototyping for chassis- and board-mounted applications.
• RoHS compliant and production-ready: Environmentally compliant manufacturing and mass production availability support scalable sourcing.
