LLG2G181MELA25

The LLG2G181MELA25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LLG series, offering a compact, high‑voltage solution with a 180 µF nominal capacitance and a 400 V rated voltage. Designed one rank smaller than the LLS series, it is suited for equipment downsizing where high-voltage filtering and energy storage are required.

Built for general‑purpose power applications, the device combines a compact radial can, polarized construction and RoHS compliance to support reliable performance in commercial and industrial designs operating within –25 °C to +85 °C.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 400 V rated voltage for high‑voltage energy storage and filtering.
• Snap‑in Terminal Package — Radial, can‑type snap‑in mounting for secure PCB installation in power assemblies.
• Compact Size for Downsizing — One rank smaller case than the LLS series, enabling reduced board footprint in space‑constrained designs; nominal size 2.5 × 2.5 cm.
• Operating Temperature & Endurance — Specified for operation from –25 °C to +85 °C with an endurance rating of 2000 hours at 85 °C under DC bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 1.16 A at 120 Hz and 1.659 A at 100 kHz for handling AC ripple in power circuits.
• Leakage Current Specification — Leakage current limited by the formula I ≤ 3√CV (µA) after 5 minutes at 20 °C, enabling predictable leakage behavior for design calculations.
• Electrical Stability — Capacitance tolerance ±20% (at 120 Hz, 20 °C) and dielectric loss tangent (tan δ) maximum of 0.15 at rated voltages up to 400 V (measured at 120 Hz, 20 °C).
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substance requirements.

Typical Applications

• Power supply smoothing — Use as bulk capacitors or output filters where 400 V rating and 180 µF capacitance provide DC link smoothing and energy buffering.
• Power conversion — Suitable for DC‑link or intermediate bus filtering in industrial and commercial power converters where compact high‑voltage capacitors are needed.
• Industrial equipment — Applied in general‑purpose industrial electronics requiring reliable high‑voltage capacitance with elevated temperature endurance.

Unique Advantages

• Space‑saving form factor — One rank smaller case compared with the LLS series helps reduce overall equipment size without sacrificing rated voltage or capacitance.
• Robust ripple handling — Specified ripple current at both low and high frequencies supports predictable thermal and electrical performance under AC loading.
• Designed for high‑voltage applications — 400 V rating enables use in high‑voltage DC link and filtering roles where lower‑voltage electrolytics are unsuitable.
• Verified endurance and shelf life — Endurance defined at 2000 hours at 85 °C and a shelf‑life characterization that includes 1000 hours at 85 °C storage, supporting long‑term reliability planning.
• Measurable leakage and loss characteristics — Clear leakage current formula and tan δ limits provide engineering‑useful parameters for system modeling and part selection.
• Regulatory compliance — RoHS conformity reduces material compliance risk in global commercial and industrial products.
