UPTW6271MRD

The UPTW6271MRD is an aluminum electrolytic capacitor in Nichicon’s UPT series. It is a radial-lead, polarized can type designed for general-purpose applications and is explicitly suited for ballast applications.

Key electrical characteristics include 270 µF capacitance at 420 V rated voltage, high ripple-current capability, and a long endurance rating (5000 hours at 105°C), making it suitable for high-stress power environments that demand compact, high-voltage capacitors.

Key Features

• Electrical Capacity: 270 µF capacitance with a rated voltage of 420 V, providing high stored energy for high-voltage applications.
• High Ripple Current: Rated ripple current of 1.2 A at 120 Hz and 1.92 A at 10 kHz, supporting circuits exposed to significant AC ripple.
• Long Life Endurance: Endurance specified at 5000 hours at 105°C under rated conditions, with defined limits for capacitance change, tan δ, and leakage current after test.
• Temperature Range: Operating temperature range of −40°C to +105°C to cover wide environmental conditions.
• Packaging and Mounting: Radial lead, can-style package with lead spacing of 1.25 cm and physical footprint L: 5 × D: 2.5 cm for compact board-level installation.
• Polarized Design and Tolerance: Polarized capacitor with capacitance tolerance of −20% to +20% at 120 Hz, 20°C.
• RoHS Compliant: Conforms to RoHS requirements as stated in the product information.

Typical Applications

• Lighting Ballasts — Suited for ballast applications where a compact, high-voltage electrolytic capacitor with high ripple capability is required.
• General-Purpose Power Circuits — Appropriate for general-purpose assemblies that require 420 V, 270 µF bulk capacitance in a radial can format.
• Industrial Equipment — Applicable where extended high-temperature endurance (5000 h at 105°C) and wide operating temperature range are necessary.

Unique Advantages

• Explicit High-Ripple Rating: Specified ripple currents at 120 Hz and 10 kHz (1.2 A and 1.92 A respectively) allow confident selection for high-ripple environments.
• Long-Term Reliability: 5000-hour endurance at 105°C provides predictable performance over extended operating life under rated conditions.
• Compact Radial Can: Small footprint (L: 5 × D: 2.5 cm) and standard radial lead spacing (1.25 cm) aid dense PCB layouts and straightforward through-hole assembly.
• Wide Operating Range: −40°C to +105°C category temperature range covers a broad set of environmental requirements.
• Measurable Loss and Leakage Limits: Datasheet-defined tan δ and leakage current limits (including leakage formula 0.06CV+10 μA after 2 minutes at 20°C) support predictable electrical behavior and qualification.
• Regulatory Compliance: RoHS compliance supports use in regions and products requiring restricted-substance conformance.
