LGL2W391MELC30

The LGL2W391MELC30 is a Nichicon LGL series aluminum electrolytic capacitor in a snap‑in terminal radial can. It provides 390 µF capacitance at a 450 V rating in an ultra‑smaller-sized 35 × 30 mm package with tray packing for mass production.

Designed for general‑purpose high‑voltage power applications, this capacitor combines a 105 °C operating range with a 2000‑hour endurance rating at 105 °C, making it suitable where elevated temperature tolerance and long service life are required.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance (at 120 Hz, 20 °C).
• High‑temperature endurance — Rated for operation from −25 °C to +105 °C with an endurance specification of 2000 hours at 105 °C (capacitance ±20%, tan δ ≤200% of initial, leakage ≤ initial).
• Snap‑in radial can package — Snap‑in terminal mounting for secure PCB attachment; package listed as radial, can ‑ snap‑in and supplied in tray packing for mass production.
• Low‑frequency and high‑frequency ripple capability — Ripple current specified as 1.28 A at 120 Hz and 1.83 A at 50 kHz for this part, with frequency coefficients up to 1.43 at 50 kHz or more (400–450 V series).
• Leakage and dissipation characteristics — Leakage current meets I ≤ 3√C (µA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) max 0.20 at 450 V (measured at 120 Hz, 20 °C).
• Compact footprint — Physical size approximately 35 × 30 mm (φ35 × 30 L) to save board space in high‑voltage designs.
• Polarized element — Polarized aluminum electrolytic construction for bulk energy storage and smoothing in DC circuits.

Typical Applications

• High‑voltage power supplies — Bulk filtering and smoothing in general‑purpose high‑voltage power supply modules where 450 V rating and elevated temperature capability are required.
• Industrial power electronics — Energy storage and ripple handling in general industrial power systems that demand long endurance at 105 °C.
• General‑purpose electronic equipment — DC bus decoupling and bulk capacitance in general‑purpose equipment and assemblies produced in volume (tray packing supports mass production).

Unique Advantages

• High nominal voltage (450 V) — Enables use in higher DC bus and power supply applications without series stacking.
• 105 °C rated with 2000 h endurance — Demonstrates long‑term stability under elevated temperature conditions with defined post‑test limits for capacitance, tan δ and leakage.
• Frequency‑aware ripple performance — Specified ripple current at 120 Hz and 50 kHz plus frequency coefficients (up to 1.43 at ≥50 kHz) clarifies performance across common ripple conditions.
• Secure snap‑in mounting — Snap‑in terminals provide robust mechanical retention for through‑hole PCB assemblies in production environments.
• Compact, production‑friendly packaging — φ35 × 30 mm footprint and tray packing streamline layout and automated assembly for high‑volume manufacturing.
• Measurable loss and leakage limits — Specified tan δ and leakage current formulas support predictable electrical behavior and selection for sensitive designs.
