LGL2G821MELC40

The LGL2G821MELC40 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor offering 820 µF capacitance at a 400 V rating. Engineered for general‑purpose applications, it combines high voltage handling, elevated temperature endurance and a compact snap‑in can package for straightforward board mounting.

Key value comes from its 105 °C operating range with a rated endurance of 2000 hours at 105 °C, a rated ripple current suited to high‑stress environments, and low leakage and loss characteristics that support reliable performance in demanding assemblies.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 400 V rated voltage for high‑voltage energy storage and filtering needs.
• High‑Temperature Endurance — Rated for operation from −25 °C to +105 °C with an endurance life specified as 2000 hours at 105 °C.
• Snap‑in Mounting — Snap‑in radial can package (35 × 40 mm) designed for secure mechanical mounting and simplified assembly.
• Ripple and Loss Characteristics — Rated ripple current 1.92 A at 120 Hz (2.746 A at 50 kHz frequency condition) and tan δ max of 0.15 at 120 Hz, 20 °C for controlled dissipation.
• Low Leakage — Leakage current specified at 1.71 mA after rated voltage application, supporting stable DC performance.
• Capacitance Tolerance & Polarization — ±20% tolerance at 120 Hz, 20 °C and polarized construction for correct orientation in circuits.
• Packaging & Availability — Supplied in tray packing and listed as mass production status from Nichicon.

Typical Applications

• General Purpose Power Systems — Provides bulk capacitance and high‑voltage capability for general‑purpose high‑voltage circuits and assemblies that require 400 V rated components.
• High‑Temperature Environments — Suited to applications that operate up to 105 °C and require components with verified 2000‑hour endurance at that temperature.
• Board‑Mount Energy Storage — Snap‑in radial can form factor allows secure mounting for systems needing compact high‑capacitance storage on printed circuit boards.

Unique Advantages

• High‑Voltage Capability: 400 V rating supports designs that require elevated DC voltage headroom without changing capacitor topology.
• Compact Snap‑in Form Factor: 35 × 40 mm radial can with snap‑in terminals simplifies mechanical retention and assembly compared with loose components.
• Designed for Elevated Temperatures: Rated operation to 105 °C and a 2000‑hour endurance specification at that temperature provide predictable life under thermal stress.
• Controlled Loss and Leakage: tan δ ≤ 0.15 and leakage current of 1.71 mA deliver predictable dissipation and low standby current for stable DC performance.
• Robust Ripple Handling: Rated ripple current (1.92 A at 120 Hz; higher-frequency capability noted) enables use in circuits with significant AC ripple stress.
• Production‑Ready Supply: Tray packing and mass production status from Nichicon support volume procurement and consistent delivery.
