LGN2P681MELA35

The LGN2P681MELA35 from Nichicon is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 680 µF at a 220 V rating in a compact snap-in radial can and is engineered for sustained operation up to 105°C.

Built to withstand long-term ripple stress, this capacitor offers a durable solution for designers needing high-capacitance, high-voltage bulk capacitance in space-conscious power designs.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 220 V rated voltage and a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• High-Temperature Endurance — Rated for operation up to 105°C and specified to withstand 3000 hours with rated ripple current applied at 105°C (endurance limits: capacitance change within ±20%, tan δ ≤ 200% of initial, leakage current ≤ initial specified value after test).
• Ripple Current Performance — Specified ripple handling of 1.78 A at 120 Hz and 2.67 A at 100 kHz, supporting sustained AC stress in power circuits.
• Package & Mounting — Snap-in terminal, radial can package for through‑hole mounting; compact physical size (L: 3.5 × D: 2.5 cm) and described as one rank smaller case size than the LGU series.
• Operating Range & Polarity — Polarized capacitor with an operating temperature range of −40°C to +105°C (for the 160–250 V range as stated in the series specifications) and series rated voltage range of 160 to 600 V.
• Regulatory & Identification — RoHS compliant; sleeve marking printed with white letters on a black sleeve for quick identification.

Typical Applications

• General-purpose power filtering — Bulk capacitance and smoothing in power supply stages where 680 µF at 220 V and robust ripple endurance are required.
• Industrial power electronics — Use in high-temperature environments up to 105°C where long ripple-life (3000 hours at 105°C) is important for reliability.
• Energy storage and decoupling — Local energy reservoir and decoupling for high-voltage circuits that need polarized electrolytic bulk capacitance in a snap-in form factor.

Unique Advantages

• High ripple endurance: Specified to withstand 3000 hours of rated ripple current at 105°C, providing long-term stability under continuous AC stress.
• Compact snap-in package: Snap-in radial can with a smaller case size than the LGU series helps reduce PCB area for through‑hole bulk capacitors.
• Clear electrical specification: Rated at 680 µF and 220 V with published ripple current values at both 120 Hz and 100 kHz to support design validation.
• Wide temperature operation: Usable across −40°C to +105°C, matching common high-temperature power environments covered by the series specifications.
• Regulatory compliance: RoHS compliant and clearly marked for identification on the sleeve.
