LLG2G102MELC50

The LLG2G102MELC50 is a Nichicon LLG series aluminum electrolytic capacitor in a snap‑in terminal, radial can package. It provides 1 mF capacitance at a 400 V rated voltage with polarized construction and is RoHS compliant.

Designed one rank smaller than the LLS series and explicitly suited for equipment downsizing, this part balances compact size with high‑voltage capability and defined ripple handling for general‑purpose power applications.

Key Features

• Capacitance & Voltage — 1 mF nominal capacitance with a 400 V rated voltage, suitable where high DC voltage handling is required.
• Compact Snap‑In Package — Radial can, snap‑in terminal mounting in an L: 5 × D: 3.5 cm envelope; one rank smaller case size than LLS for equipment downsizing.
• Operating Temperature & Lifetime — Rated for operation from −25 °C to +85 °C with an endurance of 2000 hours at 85 °C under rated DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 3.3 A at 120 Hz (low frequency) and 4.719 A at 100 kHz (high frequency), supporting AC superposition on DC in filtering applications.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20% and polarized construction; intended for circuits designed for polarized electrolytic capacitors.
• Leakage Current Specification — Leakage current conforms to the manufacturer’s formula I ≤ 3√(C·V) μA after 5 minutes at 20 °C, providing predictable leakage behavior for design calculations.
• RoHS Compliance — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — For general‑purpose capacitor needs where a 1 mF, 400 V polarized electrolytic is appropriate.
• Equipment Downsizing — Suited to designs targeting reduced case size thanks to a one‑rank smaller case than the LLS series.
• High‑Voltage Filtering and Smoothing — Used where 400 V DC filtering or smoothing is required and defined ripple current ratings are needed.

Unique Advantages

• Space‑Efficient Form Factor — One rank smaller case than LLS allows designers to reduce enclosure size without changing capacitor family.
• Clear Endurance Data — 2000 hours at 85 °C endurance rating gives predictable life expectations under specified stress conditions.
• Dual‑Frequency Ripple Ratings — Specified ripple current at both 120 Hz and 100 kHz supports performance assessment across common operating conditions.
• Predictable Leakage Behavior — Leakage current governed by I ≤ 3√CV after five minutes at 20 °C enables straightforward thermal and standby current budgeting.
• Secure Mounting — Snap‑in terminals provide robust mechanical retention for radial, can‑style installations.
• Regulatory Compatibility — RoHS compliance supports use in regions requiring restricted substances adherence.
