UPT2E181MHD

The UPT2E181MHD is an aluminum electrolytic capacitor in Nichicon’s UPT series, designed as a miniature, radial-leaded can for general-purpose applications where high ripple current and long operational life are required. It is a polarized radial lead capacitor specified for 180 µF at 250 V.

Engineered for demanding power environments, the part combines high ripple capability with a wide operating temperature range and a long endurance rating—making it appropriate for equipment that needs reliable DC filtering under continuous load.

Key Features

• Capacitance & Voltage: 180 µF nominal capacitance rated at 250 V, with tolerance ±20%.
• High ripple current capability: Specified for 720 mA at 120 Hz and 1.152 A at 10 kHz, suitable for circuits with significant AC ripple on the DC bus.
• Long endurance: Rated for 5,000 hours at 105°C under D.C. bias plus rated ripple current (series endurance specification).
• Temperature range: Operates from −40°C to +105°C to cover a broad set of industrial and commercial environments.
• Low-loss electrical characteristics: For 250 V units the datasheet lists tan δ (loss tangent) with a maximum of 0.12 at 120 Hz, 20°C.
• Radial lead package: Radial can construction with 7.5 mm lead spacing and compact body dimensions of L: 3.55 cm × D: 1.6 cm for space-constrained assemblies.
• Polarized: Designed as a polarized aluminum electrolytic capacitor for typical DC filtering applications.
• RoHS compliant: Meets RoHS directive requirements as indicated in the series datasheet.
• Leakage current specification: Series leakage current is specified as not more than 0.06CV + 10 μA after 2 minutes at 20°C, providing a measurable baseline for design verification.

Typical Applications

• Ballast applications: The UPT series is explicitly noted as suited for ballast use, where high ripple handling and long life are important.
• High-ripple power circuits: Use where elevated ripple current occurs on DC rails and stable capacitance under load is required.
• General-purpose electronic equipment: Fits a range of commercial and industrial designs that require polarized electrolytic capacitance with long endurance.

Unique Advantages

• Designed for high ripple loads: Explicit ripple current ratings at both 120 Hz and 10 kHz support applications with significant AC components on DC lines.
• Proven endurance rating: 5,000 hours at 105°C under rated conditions gives a reliable benchmark for life expectancy in elevated-temperature installations.
• Compact radial-can form factor: Small body dimensions and 7.5 mm lead spacing enable integration in tighter PCB footprints while retaining robust leaded mounting.
• Wide ambient temperature range: −40°C to +105°C operation covers many industrial and commercial deployment scenarios.
• Measurable electrical limits: Specified leakage current and loss tangent values provide concrete parameters for thermal and performance modeling.
• Regulatory compliance: RoHS compliance supports environmentally regulated product designs.
