LGR2D681MELA40

The LGR2D681MELA40 is an aluminum electrolytic capacitor in a snap‑in radial can package from Nichicon’s LGR Long Life series. This polarized capacitor is rated 680 µF at 200 V and is designed for general purpose applications that require high capacitance at elevated voltage.

Key value propositions include long‑life endurance — specified to withstand 10,000 hours of DC bias plus rated ripple current at 105°C — wide operating temperature range, and RoHS compliance.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 200 V and capacitance tolerance of ±20%.
• Long‑Life Endurance — LGR series specification: withstands 10,000 hours of DC bias plus rated ripple current at 105°C with defined limits on capacitance change, tan δ, and leakage current.
• High Temperature Rating — Operating temperature range of −40°C to +105°C for reliable performance in elevated ambient conditions.
• Ripple Current Capability — Rated ripple currents include 1.7 A at 120 Hz and 2.55 A at 50 kHz (series frequency characteristics available in the datasheet).
• Package & Mounting — Snap‑in terminal, radial can package for PCB mounting; physical size L: 4 × D: 2.5 cm (length × diameter).
• Leakage and Dissipation Characteristics — Leakage current specification follows I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ and low‑temperature impedance characteristics are defined in the series datasheet.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power circuits — Bulk capacitance and filtering in designs that require a 200 V rating and long life at elevated temperature.
• High‑voltage DC link and smoothing — Provides energy storage and ripple suppression where 680 µF at 200 V is required and sustained ripple life at 105°C is important.
• Industrial power supplies — Use in power supply stages that benefit from snap‑in mounting and long endurance under rated ripple conditions.

Unique Advantages

• Proven long‑life specification — 10,000 hours endurance at 105°C under DC bias plus rated ripple current supports designs targeting extended operational lifetimes.
• High operating temperature — Rated to +105°C, enabling reliable performance in warmer ambient environments.
• Robust ripple handling — Specified ripple current ratings at multiple frequencies (e.g., 1.7 A at 120 Hz, 2.55 A at 50 kHz) and frequency coefficients provided in the datasheet aid thermal and reliability planning.
• PCB‑friendly snap‑in form factor — Radial snap‑in terminals simplify mounting for high‑current power applications.
• RoHS compliance — Conforms to applicable RoHS directives for regulatory and environmental needs.
