UPA1E331MPD

The UPA1E331MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead package from Nichicon's UPA series. It is designed for general-purpose power applications and for use in switching power supplies where low impedance, high ripple capability and a compact footprint are required.

This 330 µF, 25 V polarized capacitor combines low impedance and verified endurance to support sustained operation across a wide temperature range of –55 °C to 105 °C, making it suitable for compact power filtering and smoothing tasks in electronics designs.

Key Features

• Capacitance and Voltage — 330 µF rated capacitance at 25 V with ±20% tolerance for predictable bulk energy storage and decoupling.
• Low Impedance — Specified impedance of 180 mΩ supports low-loss performance in power rails and filtering applications.
• Loss Angle (tan δ) — tan δ = 0.14 (measured at 20 °C, 120 Hz, 25 V) for controlled dissipation characteristics.
• High Ripple Current Capability — Low-frequency ripple current 409.5 mA at 120 Hz and high-frequency ripple current 630 mA at 10 kHz, enabling effective filtering under realistic switching conditions.
• Leakage Current — Specified leakage current of 247.5 µA for predictable standby and low-current behavior.
• Endurance — 3000 hours rated lifetime at 105 °C to support long-term reliability in elevated-temperature environments.
• Compact Radial Package — Small can size φ8 × 11.5 mm with 3.5 mm lead spacing (±0.5 mm) for dense PCB layouts and through-hole assembly.
• RoHS Compliant — Meets RoHS requirements for restricted substances.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit assembly and inventory preferences.

Typical Applications

• Switching Power Supplies — Supports output filtering and smoothing where low impedance and high ripple handling are required.
• General-Purpose Electronics — Used for bulk decoupling and energy storage in a wide range of consumer and industrial circuits.
• Compact Power Modules — Small φ8 can and 3.5 mm lead spacing fit tight PCB layouts requiring through-hole radial components.

Unique Advantages

• Measured Low Impedance: 180 mΩ impedance reduces voltage ripple and improves power rail stability.
