ULD2C6R8MED

The ULD2C6R8MED is a miniature, radial-lead aluminum electrolytic capacitor from the Nichicon ULD series designed for general-purpose power applications. It combines a 6.8 µF capacitance with a 160 V rated voltage in a compact φ6.3 × 11 mm can for through-hole mounting.

Engineered for extended operation at elevated temperature, the part supports a -40℃ to 105℃ operating range and a rated endurance of 12,000 hours at 105℃, making it suitable for applications that require stable filtering and decoupling over long service life.

Key Features

• Capacitance and Tolerance — 6.8 µF nominal capacitance with ±20% tolerance (120 Hz, 20℃) for predictable filtering performance.
• Voltage Rating — Rated for 160 V DC, enabling use in higher-voltage power rails and supply circuits.
• Low- and High-Frequency Ripple Handling — Low-frequency ripple current of 55 mA at 120 Hz and high-frequency ripple current of 104.5 mA at 100 kHz, supporting both mains-frequency and high-frequency switching applications.
• Loss Tangent (tan δ) — tan δ = 0.24 measured at 20℃, 120 Hz and 160 V to characterize dissipation factor under standard test conditions.
• Leakage Current — Specified leakage current of 143.52 µA, useful for estimating standby losses in power circuitry.
• Robust Temperature Range and Endurance — Operates from -40℃ to 105℃ with a rated lifetime of 12,000 hours at 105℃.
• Compact Radial Package — φ6.3 × 11 mm can with 2.5 mm lead spacing (±0.5 mm) and radial lead mounting for easy through-hole assembly.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to support volume assembly and handling preferences.

Typical Applications

• LED lighting power supplies — Small, long-life smoothing and filtering in LED driver circuits where elevated operating temperature endurance is required.
• General-purpose power filtering — Decoupling and ripple suppression on higher-voltage DC rails in industrial and consumer electronics.
• DC/DC converters — Input/output filtering for through-hole designs requiring compact, higher-voltage capacitors.

Unique Advantages

• Compact footprint: φ6.3 × 11 mm can provides a miniature solution for space-constrained through-hole boards.
• High-voltage capability: 160 V rating lets designers use a single component for higher-voltage rails, reducing BOM complexity.
• Long-term thermal endurance: Rated for 12,000 hours at 105℃, supporting designs that must operate reliably at elevated temperatures.
• Broad frequency ripple performance: Specified ripple currents at 120 Hz and 100 kHz enable use across both mains-frequency and switching-power applications.
• Predictable electrical characteristics: Specified tan δ and leakage current values allow accurate thermal and leakage budgeting in power designs.
• Through-hole mounting convenience: Radial leads with 2.5 mm spacing facilitate manual assembly and standard PCB layouts.
