LGG2G681MELB50

The LGG2G681MELB50 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGG series. It provides 680 µF capacitance at a 400 V rated voltage in a radial, can‑style snap‑in package designed for general‑purpose use.

Designed one rank smaller than the LGN series and compliant with the RoHS directive, this LGG part is suited for equipment downsizing while offering series‑level performance characteristics for temperature stability, ripple handling and long‑term endurance.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 400 V for general‑purpose high‑voltage applications.
• Package & Mounting — Radial, can‑style snap‑in terminal configuration for robust mechanical retention and straightforward PCB mounting.
• Compact Size — One rank smaller case than the LGN series to support equipment downsizing; nominal size L: 5 × D: 3 cm.
• Operating Temperature & Lifetime — Rated for operation from −25 °C to +105 °C with a 2000 hour endurance at 105 °C under DC bias plus rated ripple current.
• Ripple Current Capability — Specified ripple current handling of 1.8 A at 120 Hz and 2.574 A at 100 kHz (series values applied to this part).
• Electrical Characteristics — Capacitance tolerance ±20% at 120 Hz/20 °C; leakage current defined by I ≤ 3√CV (μA) after 5 minutes at 20 °C; maximum tan δ 0.15 at 120 Hz, 20 °C for rated voltages up to 420 V.
• Low‑temperature Stability — Series impedance stability specified (Z(−25 °C)/Z(+20 °C) up to 8 for 400–450 V range), supporting performance in cooler ambient conditions.
• RoHS Compliance — Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power circuits — Provides bulk capacitance and smoothing for general‑purpose designs requiring 680 µF at 400 V in a snap‑in can package.
• Equipment downsizing — One‑rank‑smaller case size compared to LGN to help reduce enclosure and board space in compact systems.
• High‑temperature environments — Endurance rated at 2000 hours at 105 °C for applications that subject capacitors to elevated operating temperatures.

Unique Advantages

• Space‑efficient form factor — Smaller case sizing relative to LGN enables designers to reduce system footprint without changing capacitor family characteristics.
• High voltage capability — 400 V rating allows use in higher‑voltage general‑purpose circuits where large capacitance is required.
• Designed for sustained thermal stress — 2000 hours endurance at 105 °C demonstrates long‑term reliability under high temperature and DC bias conditions.
• Measured ripple performance — Specified ripple currents at both low and high frequencies (120 Hz and 100 kHz) provide quantifiable handling for real‑world filtering and decoupling loads.
• Predictable electrical behavior — Clear leakage current formula and tan δ limits enable accurate design margin and verification during qualification.
• Regulatory compliance — RoHS compliance supports use in products targeting restricted‑substance requirements.
