LLS2G561MELC

The LLS2G561MELC is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LLS series, designed for general‑purpose power applications. It delivers 560 µF at a 400 V rating in a radial can snap‑in package with polarized terminals and is specified for operation from –25°C to 85°C.

Engineered for sustained ripple handling, this part is rated to withstand 3000 hours of applied rated ripple current at 85°C and is RoHS‑compliant, making it suitable for industrial and commercial equipment requiring robust bulk energy storage and filtering.

Key Features

• Electrical Performance — 560 µF capacitance with ±20% tolerance (measured at 120 Hz, 20°C) and a 400 V rated voltage for high‑voltage power circuits.
• Ripple Current Capability — Rated ripple currents of 2.85 A at 120 Hz and 4.075 A at 50 kHz, and designed to endure 3000 hours of rated ripple current at 85°C.
• Reliability & Endurance — Endurance specification: after 3000 hours at 85°C with DC bias plus rated ripple current, capacitance change within ±20%, tan δ up to 200% of initial spec, and leakage current not exceeding initial specification.
• Temperature & Low‑Temperature Behavior — Operating temperature range –25°C to 85°C for 350–450 V parts; impedance ratio Z(–25°C)/Z(+20°C) specified (350–450 V) at up to 8, supporting stable performance across the rated temperature range.
• Leakage and Dissipation — Leakage current defined by I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ (loss tangent) for 400 V rated parts specified with a maximum of 0.20 at 120 Hz, 20°C.
• Package & Mounting — Radial can, snap‑in terminal type for secure through‑hole mounting; physical size approximately L: 4 cm × D: 3.5 cm with a seated height specification for board layout.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply smoothing and bulk storage — Provides bulk capacitance and ripple handling in high‑voltage power supplies and industrial power modules.
• DC link and energy buffering — Used where polarized high‑voltage capacitance is required for energy buffering and decoupling in general‑purpose equipment.
• Industrial electronics — Suitable for general‑purpose industrial control and power conversion systems that require long‑life ripple endurance at elevated temperatures.

Unique Advantages

• High‑voltage capability: 400 V rated voltage enables use in higher‑voltage circuits without additional series stacking.
• Long ripple endurance: Specified to withstand 3000 hours of rated ripple current at 85°C, supporting designs that require sustained ripple handling.
• Quantified reliability metrics: Endurance and shelf‑life limits (capacitance, tan δ, leakage) are specified, simplifying qualification and lifetime planning.
• Clear leakage specification: Leakage current defined by I ≤ 3√CV (µA) after 5 minutes at 20°C, allowing predictable standby loss budgeting.
• RoHS compliance: Meets RoHS directives for environmentally regulated production environments.
