The UPT2E331MRD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPT series. It delivers 330 µF capacitance at a 250 V rating in a compact φ22 × 40 mm can designed for general-purpose power applications.

Engineered for high ripple handling and long endurance, this polarized capacitor is suited to applications that require robust ripple-current performance, stable operation from –40℃ to 105℃, and a 5000-hour life at 105℃.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a rated voltage of 250 V and capacitance tolerance of −20% to +20%.
• High ripple-current capability: Low-frequency ripple current 1.05 A (120 Hz) and high-frequency ripple current 1.68 A (10 kHz) for power-filtering and converter applications.
• Endurance and temperature range: Rated for 5000 hours at 105℃ and specified to operate from −40℃ to 105℃.
• Electrical loss and leakage: Tangent of loss angle (tan δ) max 0.12 (measured at 20℃, 120 Hz) and a leakage current value of 4960 µA as provided in product data.
• Package and mounting: Radial-lead can package with 10 mm lead spacing (±0.5 mm) and a physical size of φ22 × 40 mm for through-hole mounting.
• Packaging options: Supplied in bulk (no terminal forming) or bag packing to suit assembly preferences.
• Compliance: RoHS compliant (per product environmental data).
• Status: End Of Life (product status as provided).

Typical Applications

• Ballast and lamp drives: Designed for applications with significant ripple currents, where sustained ripple performance and endurance are required.
• Power supply filtering: Smoothing and decoupling in AC/DC and DC/DC converters operating up to 250 V, leveraging the capacitor's ripple-current ratings.
