UPT2P391MRD

The UPT2P391MRD is an aluminum electrolytic capacitor in a radial-lead can package designed for general-purpose power applications and ballast circuits. It delivers a compact solution for 220 V systems where high ripple current capability and extended operating life are required.

With a 390 µF capacitance, polarized construction and a rated voltage of 220 V, this radial-lead device targets designers needing robust ripple handling, elevated temperature endurance and a small footprint for power-filtering and smoothing tasks.

Key Features

• Capacitance & Voltage: 390 µF capacitance rated at 220 V for mid‑to‑high voltage power circuits.
• High ripple current capability: Rated ripple current 1.15 A at 120 Hz and 1.84 A at 10 kHz; frequency coefficient data available in the series specification.
• Long life at elevated temperature: Endurance specified as 5000 hours at 105 °C under DC bias plus rated ripple current.
• Wide operating temperature: Specified for –40 °C to +105 °C operation.
• Radial can package & mounting: Radial lead / radial can construction with 1 cm lead spacing and a compact footprint (L: 4 × D: 2.2 cm).
• Electrical reliability data: Leakage current specified (after 2 minutes at 20 °C) as not more than 0.06CV + 10 μA (series specification).
• Tolerance & polarity: Capacitance tolerance ±20%; polarized capacitor for correct polarity installation.
• Environmental compliance: RoHS compliant.

Typical Applications

• Ballast circuits: Suited for ballast applications requiring sustained ripple handling at elevated temperatures.
• Power supply smoothing: 220 V power supply ripple suppression and energy storage in compact power modules.
• General-purpose power electronics: Filtering and decoupling in equipment that requires a compact, long‑life electrolytic capacitor.

Unique Advantages

• High ripple endurance: Measurable ripple current ratings at 120 Hz and 10 kHz reduce thermal stress and support reliable operation in ripple‑intensive circuits.
• Compact footprint: Small radial can dimensions (L: 4 × D: 2.2 cm) and 1 cm lead spacing simplify integration into space‑constrained layouts.
• Designed for elevated temperatures: 5000 hours endurance at 105 °C provides predictable lifetime performance in hot operating environments.
• Clear electrical parameters: Defined leakage current formula and capacitance tolerance make performance easy to model in designs.
• Regulatory compliance: RoHS status supports use in products requiring restricted‑substance compliance.
