UCS2W6R8MPD

The UCS2W6R8MPD is a miniature, high‑reliability aluminum electrolytic capacitor from Nichicon's UCS series. It is a polarized, radial‑lead device specified for high ripple current and long operational life in compact high‑voltage applications.

Targeted use cases include power supply and ballast applications as well as general‑purpose high‑voltage circuits that require a compact 450 V capacitor with extended lifetime and RoHS compliance.

Key Features

• Electrical — 6.8 µF rated capacitance with ±20% tolerance and a 450 V working voltage, suitable for high‑voltage DC circuitry.
• High ripple current — Rated for 280 mA ripple at 100 kHz and 140 mA at 120 Hz, enabling effective handling of AC ripple in power stages.
• Low leakage — Specified leakage current of 222.4 µA (measured per product data), supporting stable performance in DC applications.
• Reliability & life — Designed for long life with 8000 hours at +105°C (for φ10 × 20 case sizes) under rated conditions.
• Thermal range — Wide operating temperature range from −40°C to +105°C for demanding thermal environments.
• Mechanical & packaging — Compact φ10 × 20 mm can with 5 mm lead spacing, radial lead mounting and bulk/bag packaging for production assembly.
• Compliance — RoHS‑compliant construction as provided in the product data.

Typical Applications

• Power supplies — High‑voltage DC filtering and ripple handling in power conversion stages, leveraging the 450 V rating and high ripple current capability.
• Ballasts — Suited for ballast applications where high ripple endurance and long life at elevated temperature are required.
• General‑purpose high‑voltage circuits — Compact radial‑lead capacitor for designs that require a small footprint, polarized high‑voltage energy storage with proven life performance.

Unique Advantages

• High ripple tolerance: 280 mA at 100 kHz and 140 mA at 120 Hz provide headroom for ripple in power stages and ballast circuits.
• Extended operating life: 8000 hours at +105°C for the φ10 × 20 case supports longer maintenance intervals and higher uptime.
• Compact, production‑ready package: φ10 × 20 mm can with 5 mm lead spacing and bulk/bag packaging simplifies line assembly in volume manufacturing.
• Wide temperature operation: −40°C to +105°C rating enables use across varied thermal environments without derating beyond specified limits.
• Regulatory compliance: RoHS‑compliant construction aligns with environmental requirements for many electronic systems.
