UPT2E271MHD

The UPT2E271MHD is an aluminum electrolytic capacitor from Nichicon's UPT series designed for miniaturized, high-ripple applications. It delivers 270 µF at 250 V in a radial-can package with radial lead mounting and a compact footprint (L: 4 × D: 1.8 cm).

Engineered for general-purpose and ballast applications, this capacitor combines high ripple-current capability with a long rated life at elevated temperatures, making it suitable for power filtering and demanding AC/DC circuits where sustained performance is required.

Key Features

• Capacitance and Voltage: 270 µF rated capacitance at 250 V — suitable for energy storage and smoothing in medium-voltage power circuits.
• Tolerance & Polarization: ±20% capacitance tolerance at 120 Hz and polarized construction for correct-electrode mounting in DC circuits.
• High Ripple Current: Rated ripple current of 950 mA at 120 Hz and 1.52 A at 10 kHz, supporting heavy AC ripple conditions common in ballast and power supply designs.
• Frequency Coefficient of Rated Ripple: Frequency-dependent coefficients are provided (e.g., 1.00 at 120 Hz, 1.60 at 10 kHz or more) to size ripple capability across frequencies.
• Thermal Endurance: Operates from −40°C to +105°C with a rated life of 5000 hours at 105°C under DC bias plus rated ripple current; endurance limits include capacitance change within ±20% and leakage current within initial specified value after test.
• Leakage Current Specification: Leakage current after 2 minutes at 20°C is specified as not more than 0.06CV + 10 (µA), enabling predictable design margins for standby and steady-state currents.
• Package & Mounting: Radial lead, radial-can package with 7.5 mm lead spacing for through-hole PCB designs and robust mechanical anchoring.
• Environmental Compliance: RoHS compliant.
• Manufacturer & Series: Nichicon UPT series — miniature, high-ripple, long-life aluminum electrolytic capacitors.

Typical Applications

• Ballast Circuits: Suited for ballast application as noted in the product documentation, offering the ripple-handling and thermal endurance required in lamp ballast power paths.
• Power Filtering: Used in general-purpose power supplies and filter networks to smooth DC output and manage ripple currents at multiple frequencies.
• Industrial Power Equipment: Applicable where robust ripple performance and long life at elevated temperatures are required for reliable operation.

Unique Advantages

• High ripple-current capability: Explicit rated ripple currents at 120 Hz and 10 kHz plus frequency coefficients allow accurate thermal and ripple sizing for the application.
• Long elevated-temperature life: 5000 hours at 105°C under DC bias and rated ripple current provides predictable longevity for designs exposed to sustained heat.
• Clear leakage specification: A quantified leakage-current formula (0.06CV + 10 µA after 2 minutes at 20°C) supports tight current budgeting in low-leakage designs.
• Compact radial-can package: Small physical footprint (L: 4 × D: 1.8 cm) and 7.5 mm lead spacing suit space-constrained through-hole assemblies.
• RoHS compliant: Meets RoHS requirements for regulatory and environmental compliance in deployed products.
