UPTW6181MRD6

The UPTW6181MRD6 is an aluminum electrolytic capacitor from Nichicon's UPT series, provided in a radial can with radial lead mounting. It delivers 180 µF capacitance at a 420 V rating in a compact, miniature package tailored for general-purpose and ballast applications.

Designed for demanding environments, the UPTW6181MRD6 combines high ripple-current capability and long life performance with RoHS compliance, supporting operation from −40 °C to +105 °C and an endurance rating of 5000 hours at 105 °C.

Key Features

• Capacitance & Voltage: 180 µF at 420 V providing bulk energy storage for high-voltage circuits.
• High ripple-current performance: Rated ripple current of 950 mA at 120 Hz and 1.52 A at 10 kHz to support AC-biased and high-frequency loads.
• Long-life endurance: Specified lifetime of 5000 hours at 105 °C under D.C. bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage current after the endurance test.
• Wide operating temperature range: −40 °C to +105 °C for reliable performance across common industrial environments.
• Low leakage specification: Leakage current after 2 minutes at 20 °C is not more than 0.06CV + 10 µA (per datasheet), enabling predictable standby and bias behavior.
• Radial-can package: Radial lead, polarized can package with 1.25 cm lead spacing for through-hole PCB mounting and straightforward assembly.
• RoHS compliant: Meets RoHS directive requirements for environmental compliance.

Typical Applications

• Ballast applications: Suited for ballast circuits where high ripple current capability and long life are required.
• General-purpose high-voltage equipment: Provides bulk capacitance and energy buffering in 400–420 V class power circuits and assemblies.
• Radial-lead PCB assemblies: Radial-can mounting and 1.25 cm lead spacing simplify integration into through-hole designs that need compact, high-voltage capacitors.

Unique Advantages

• High ripple tolerance: Explicit ripple ratings at both low (120 Hz) and high (10 kHz) frequencies reduce thermal stress and extend operational life under AC-biased conditions.
• Durability under heat: Endurance specified at 5000 hours at 105 °C supports sustained performance in elevated-temperature environments.
• Predictable leakage behavior: Leakage current defined by the 0.06CV + 10 µA formula enables accurate margining in bias and standby calculations.
• Compact footprint for high-voltage use: Miniature can size (L: 4 × D: 2.5 cm) and radial lead form factor pack high voltage and capacitance into a small assembly area.
• Regulatory readiness: RoHS compliance simplifies deployment in regulated markets and design flows.
• Polarized for DC systems: Designed as a polarized aluminum electrolytic to match high-voltage DC filtering and energy-storage roles.
