UBR2W500MND

The UBR2W500MND is a high-voltage, miniature aluminum electrolytic capacitor in a radial can package from Nichicon's UBR series. It provides 50 µF capacitance at a 450 V rating with polarized radial leads and is intended for general-purpose high-voltage power applications.

Designed for demanding thermal environments, the capacitor offers long-life assurance with a rated load life of 5000 hours at 125°C and RoHS compliance (2011/65/EU, (EU)2015/863), making it suitable for communication base station power supplies and similar high-voltage power systems.

Key Features

• Electrical Rating: 50 µF capacitance with a 450 V rated voltage; capacitance tolerance ±20% at 120 Hz, 20°C.
• High Ripple Current: Rated for 400 mA at 120 Hz and 600 mA at 100 kHz, supporting applications with significant AC ripple on DC rails.
• Long Life at Elevated Temperature: Load life specified as 5000 hours at 125°C under rated DC bias plus rated ripple current.
• Operating Temperature Range: −40°C to +125°C suitable for high-temperature environments.
• Package & Mounting: Radial can package with radial lead mounting and 5.0 mm lead spacing; compact physical size (L: 3.55 × D: 1.25 cm).
• Polarized Device: Aluminum electrolytic construction requires correct polarity in circuit placement.
• Standards Compliance: RoHS compliant to 2011/65/EU and (EU)2015/863.

Typical Applications

• Communication Base Station Power Supplies — smoothing and bulk energy storage for high-voltage rails in telecom power systems where long life at elevated temperature is required.
• High‑Voltage Power Filtering — decoupling and ripple suppression on 450 V DC links and power supplies in industrial or commercial equipment.
• General‑Purpose High‑Voltage Circuits — use wherever a compact, polarized aluminum electrolytic capacitor with 450 V rating and high ripple capability is needed.

Unique Advantages

• High-Voltage Capability: 450 V rating allows direct use on elevated DC rails without series stacking.
• Strong Ripple Handling: Rated ripple currents (400 mA @120 Hz; 600 mA @100 kHz) help manage thermal stress and reduce ripple-induced voltage variation.
• Extended High‑Temperature Endurance: 5000-hour load life at 125°C provides predictable lifetime performance in hot operating environments.
• Compact Radial Can Package: Small footprint (L: 3.55 × D: 1.25 cm) and radial leads simplify through-hole mounting in dense assemblies.
• Regulatory Compliance: RoHS compliance supports designs that must meet lead-restriction requirements.
