LGN2C821MELZ35

The LGN2C821MELZ35 is an aluminum electrolytic capacitor from Nichicon’s LGN series, featuring a snap‑in terminal radial can and a 160 V, 820 µF rating. It is a smaller‑sized, 105°C‑rated snap‑in capacitor designed for general purpose use.

Built for sustained ripple endurance, this part withstands 3000 hours of rated ripple current at 105°C and provides stable electrical performance across a wide operating temperature range.

Key Features

• Electrical performance – 820 µF capacitance at 160 V with a capacitance tolerance of ±20% (120 Hz, 20°C).
• High ripple endurance – Specified to withstand 3000 hours application of rated ripple current at 105°C.
• Dual‑frequency ripple capability – Rated ripple current: 2 A at 120 Hz and 3 A at 100 kHz to support both low‑ and high‑frequency filtering tasks.
• Thermal range and reliability – Operating temperature range from −40°C to +105°C with endurance and shelf‑life characteristics defined by the LGN series.
• Package and mounting – Radial, can snap‑in package for secure PCB mounting; mounting type: Snap In.
• Polarized aluminum electrolytic – Designed for polarized applications where electrolytic capacitance is required.
• Series electrical characteristics – Meets LGN series specifications for tan δ (max. 0.15 for 160–420 V at 120 Hz) and leakage current behavior after rated voltage application per the datasheet.
• RoHS compliant – Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact dimensions – Physical size: L: 3.5 × D: 2.2 cm (22 × 35 mm can size); smaller case size than LGU series equivalents.

Typical Applications

• General‑purpose power filtering – Bulk smoothing and ripple suppression in circuits that require 160 V, 820 µF capacitance with robust ripple handling.
• High‑temperature electronics – Circuits operating up to 105°C where sustained ripple endurance and long life at elevated temperature are required.
• PCB power assemblies – Snap‑in radial can for secure board mounting in power modules and power supply assemblies.

Unique Advantages

• Compact, smaller case – One rank smaller case size than LGU, enabling denser board layouts while retaining high capacitance.
• Long ripple‑endurance life – Rated to withstand 3000 hours of rated ripple current at 105°C, supporting reliable operation in demanding thermal environments.
• Broad thermal performance – −40°C to +105°C operating range for use across a wide set of environments.
• Multi‑frequency ripple handling – Specified ripple current values at both 120 Hz and 100 kHz to address common power conversion and filtering needs.
• Secure snap‑in mounting – Radial snap‑in can provides mechanical stability for PCB power sections.
• Regulatory compliance – RoHS compliance simplifies environmental regulatory acceptance.
