UPT2W151MRD6

The UPT2W151MRD6 is a radial-lead, miniature aluminum electrolytic capacitor from Nichicon’s UPT series. It provides 150 µF capacitance at a 450 V rating in a compact φ25 × 40 mm can, optimized for high ripple current and long endurance.

Designed for general-purpose power-electronics applications and specifically noted as suited for ballast applications, this component delivers high ripple capability, a wide operating temperature range, and extended life for demanding AC/DC and power-supply environments.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance.
• High Ripple Current — Low-frequency ripple current 920 mA (120 Hz) and high-frequency ripple current 1.472 A (10 kHz), supporting high-stress power applications.
• Long Endurance — Rated for 5000 hours at 105°C with specified post-endurance limits for capacitance, tan δ and leakage current.
• Loss and Leakage — tan δ (DF) up to 0.20 measured at 20°C, 120 Hz (for 450 V); leakage current specified at 4060 µA for this part.
• Temperature Range — Operates across –40°C to +105°C, suitable for elevated-temperature environments.
• Package & Mounting — Radial lead (can) package, size φ25 × 40 mm, lead spacing 12.5 mm (±0.5 mm); available in Bulk (no terminal forming) or Bag packing.
• Compliance — RoHS compliant as specified in the product data.
• Product Status — End Of Life.

Typical Applications

• Ballasts — Suited for ballast applications requiring high ripple handling and long operational life at elevated temperatures.
• Power-supply smoothing — Useful for general-purpose smoothing and energy storage in power conversion circuits where 450 V rating and 150 µF capacitance are required.
• High-ripple power circuits — Applicable in designs that demand sustained ripple current capability at both low and high frequencies.

Unique Advantages

• High ripple capability: Specified ripple currents of 920 mA (120 Hz) and 1.472 A (10 kHz) allow reliable operation under heavy AC stress.
• Extended high-temperature life: 5000-hour endurance at 105°C supports longer service intervals in thermally demanding systems.
• High-voltage rating: 450 V rating enables use in high-voltage rails and power-conversion stages.
• Compact, radial-lead package: φ25 × 40 mm can with 12.5 mm lead spacing provides a space-efficient solution for through-hole assemblies.
• RoHS compliant: Meets environmental directive requirements as documented in the product data.
• Measured electrical characteristics: Specified tan δ and leakage current values (tan δ 0.20 at 450 V; leakage 4060 µA) give clear performance expectations for circuit design.
