UHV0J681MPD

The UHV0J681MPD is a Nichicon UHV-series aluminum electrolytic capacitor in a radial-lead can designed for general-purpose power filtering and decoupling in compact electronic assemblies. It combines a 680 µF capacitance at 6.3 V with a low-impedance construction optimized for high-frequency ripple handling.

Targeted at applications that require high ripple capability in a small, through-hole form, this part delivers measurable ripple performance, long endurance, and wide operating temperature range while remaining RoHS compliant.

Key Features

• Capacitance & Voltage — 680 µF capacitance rated at 6.3 V with ±20% tolerance for bulk smoothing and decoupling in low-voltage rails.
• Low Impedance — Measured impedance of 181 mΩ supports effective high-frequency performance and reduced voltage ripple under load.
• High Ripple Current — Rated for 540 mA at low frequency (120 Hz) and 900 mA at high frequency (100 kHz) to support demanding ripple conditions.
• Thermal and Endurance — Rated operating range −40 °C to 105 °C with endurance of 6000 hours at 105 °C, enabling sustained operation in thermally demanding environments.
• Leakage and Polarization — Polarized aluminum electrolytic design with measured leakage current of 42.84 µA (after standard test conditions).
• Radial Through-Hole Package — φ8 mm can with radial leads and 3.5 mm lead spacing (±0.5 mm tolerance); available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• Power filtering and decoupling — Smooths and stabilizes low-voltage power rails using 680 µF capacitance and low impedance to reduce ripple and transient noise.
• Compact DC‑DC converter outputs — Small φ8 mm radial can and high-frequency ripple rating (900 mA at 100 kHz) suit compact converter output stages.
• General-purpose electronics — Suitable for general-purpose smoothing and energy storage where a polarized electrolytic with long endurance and wide temperature range is needed.

Unique Advantages

• High ripple capability in a small can — 900 mA at 100 kHz and 540 mA at 120 Hz in a φ8 mm radial package reduces the need for larger components.
• Low impedance for improved performance — 181 mΩ impedance supports better high-frequency behavior and lower voltage drop under AC ripple conditions.
• Extended endurance at elevated temperature — 6000 hours rated life at 105 °C provides predictable long-term performance in heat-stressed designs.
• Wide operating temperature — −40 °C to 105 °C supports deployment across a variety of environmental conditions.
• Compact radial form factor — Radial lead mounting and tight 3.5 mm lead spacing enable easy placement in through-hole and mixed-technology assemblies.
• Regulatory compliance — RoHS compliance simplifies material-selection and regulatory considerations.
