LGN2P821MELA40

The LGN2P821MELA40 is a snap-in terminal, large-can aluminum electrolytic capacitor from Nichicon’s LGN series. It provides 820 µF capacitance at a 220 V rating in a radial, snap-in can package designed for general-purpose applications.

Engineered for elevated-temperature endurance, this part withstands rated ripple current for 3000 hours at 105 °C and is RoHS compliant, making it suitable for designs that require sustained ripple handling and reliable long-term performance.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance with a 220 V rated voltage and ±20% tolerance (at 120 Hz, 20 °C).
• High-Temperature Endurance — Endurance specified as 3000 hours at 105 °C with rated ripple current applied.
• Ripple Current Capability — Specified ripple current of 1.93 A at 120 Hz and 2.895 A at 100 kHz to support AC ripple stress in circuits.
• Snap-In Radial Can Package — Snap-in mounting type in a radial can (size: L 4.0 × D 2.5 cm) for secure PCB installation and straightforward assembly.
• Wide Operating Temperature — Rated for operation from −40 °C to +105 °C.
• Leakage and Loss Characteristics — Leakage current and tan δ governed by LGN series specifications; leakage current follows I ≤ 3/√C (µA) after 5 minutes at 20 °C as defined in the datasheet.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose circuits — Intended for general-purpose use where a high-value, high-voltage electrolytic capacitor is required with robust temperature and ripple performance.
• Snap-in mounting designs — Appropriate for assemblies that use radial, snap-in can capacitors to simplify board mounting and mechanical retention.
• High-temperature environments — Suitable for applications that must sustain operation up to 105 °C with long-duration ripple current exposure (3000 hours at 105 °C).

Unique Advantages

• Long-duration ripple endurance — Rated to withstand 3000 hours of rated ripple current at 105 °C, providing predictable performance under prolonged thermal and electrical stress.
• Substantial ripple handling — Specified ripple currents at both 120 Hz and 100 kHz support designs with significant AC ripple requirements.
• Compact radial can footprint — One-rank smaller case sizing relative to the LGU series enables a more compact installation while keeping high capacitance and voltage rating.
• Wide operating temperature range — −40 °C to +105 °C rating covers many demanding environments where elevated temperature tolerance is required.
• RoHS compliance — Meets RoHS requirements (2011/65/EU, (EU)2015/863) for regulatory and manufacturing consistency.
