LGU2P391MELA

The LGU2P391MELA from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, rated 220 V with 390 µF capacitance and ±20% tolerance. It is a general‑purpose, radial can (snap‑in) device designed for power applications that require high ripple handling and extended endurance at elevated temperatures.

Key value propositions include high ripple current capability across low and high frequencies, long endurance at 105°C (3000 hours), low leakage, and a compact φ25×30L package supplied in tray packing for production use.

Key Features

• Capacitance & Voltage — 390 µF capacitance with a 220 V rated voltage and ±20% tolerance, suitable for general‑purpose power circuits.
• Snap‑In Radial Can Package — Snap‑in terminal mounting for secure board installation; package form listed as radial, can - snap‑in.
• Temperature Range & Endurance — Operating temperature −40°C to +105°C with endurance of 3000 hours at 105°C under rated ripple conditions.
• Ripple Current Performance — Low‑frequency ripple current 1.4 A at 120 Hz and high‑frequency ripple current 2.1 A at 50 kHz to support demanding power applications.
• Low Leakage & Dissipation Factor — Specified leakage current of 870 µA and tan δ (DF) of 0.15 measured at 20°C and 120 Hz for predictable loss characteristics.
• Compact Dimensions — Size φ25×30L (approximately 3 × 2.5 cm) with a maximum seated height of 1.181 inch for space‑constrained layouts.
• Compliance & Availability — RoHS‑compliant and in mass production; supplied in tray packing for manufacturing efficiency.

Typical Applications

• Power Supply Filtering — Provides bulk capacitance and smoothing in 220 V general‑purpose power supplies where high ripple handling is required.
• Industrial Power Modules — Suitable for general‑purpose industrial power equipment that operates up to 105°C and needs long endurance capacitors.
• High‑Frequency Ripple Management — Handles high‑frequency ripple currents (2.1 A at 50 kHz), useful in circuits with switching components or high ripple spectra.

Unique Advantages

• High ripple capability: Rated ripple currents of 1.4 A (120 Hz) and 2.1 A (50 kHz) reduce thermal stress and support robust power conditioning.
• Long high‑temperature life: 3000 hours endurance at 105°C provides predictable performance for designs that operate under sustained elevated temperatures.
• Controlled losses and leakage: tan δ of 0.15 and 870 µA leakage current give low dissipation and stable performance over time.
• Compact, production‑ready package: φ25×30L snap‑in can in tray packing eases assembly and supports volume manufacturing.
• RoHS compliant and mass produced: Conforms to RoHS requirements and is available in production quantities for supply stability.
