UCA2G6R8MPD

The UCA2G6R8MPD is a miniature, polarized aluminum electrolytic capacitor from Nichicon's UCA series, designed for general-purpose power applications. It delivers 6.8 µF capacitance at a 400 V rating in a compact radial-can package, combining high ripple-current capability and long life for space-constrained power supplies and ballast circuits.

Key Features

• Voltage & Capacitance — Rated at 400 V with 6.8 µF capacitance and ±20% tolerance, suitable for high-voltage DC filtering and energy storage in power circuits.
• High Ripple Current — Rated ripple current of 220 mA at 100 kHz and 110 mA at 120 Hz, allowing effective smoothing under high-frequency and low-frequency ripple conditions.
• Low Leakage — Leakage current calculated at 208.8 µA (after 1 minute at 20 °C), supporting low-loss DC applications.
• Long Life — Rated for 10,000 hours at 105 °C, providing durability for sustained thermal and electrical stress.
• Temperature Range — Operational from −25 °C to +105 °C to accommodate a wide range of ambient environments.
• Compact Radial Package — Radial lead, can-type construction with 5.0 mm lead spacing and overall dimensions L: 1.6 cm × D: 1.0 cm, enabling through-hole mounting in compact layouts.
• RoHS Compliant — Manufactured in accordance with RoHS requirements.

Typical Applications

• Power Supplies — Bulk and output filtering in high-voltage DC power supplies where compact size and high ripple handling are required.
• Ballasts and Lamp Drivers — Smoothing and energy buffering in ballast circuits, leveraging the 400 V rating and long life at elevated temperatures.
• Industrial Electronics — General-purpose DC filtering and decoupling in industrial control equipment operating across −25 °C to +105 °C.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage DC circuits without series stacking.
• Compact footprint: Small can dimensions (L: 1.6 cm × D: 1.0 cm) and 5 mm lead spacing save PCB area in dense assemblies.
• Robust ripple handling: 220 mA at 100 kHz supports modern switching power topologies with significant high-frequency ripple components.
• Engineered for longevity: 10,000 hours life at 105 °C provides predictable end-of-life behavior for thermal and load-stressed designs.
• Predictable leakage: Leakage current of 208.8 µA (per rated capacitance and voltage) aids low-current budget designs.
• Through-hole reliability: Radial leaded can package simplifies mounting and replacement in serviceable equipment.
