LLS2E821MELC

The LLS2E821MELC is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LLS series, specified for 250 V and 820 µF with ±20% tolerance. It is engineered for general‑purpose power applications that require bulk capacitance and sustained ripple current capability in a radial, snap‑in can package.

Key value propositions include high rated ripple current capability (2.96 A at 120 Hz and 4.44 A at 50 kHz), long endurance (3,000 hours at 85°C under rated ripple conditions), and a wide operating temperature range of –40°C to +85°C. The part is RoHS compliant and available in tray packing for mass production use.

Key Features

• Electrical Rating — 820 µF capacitance at a 250 V rated voltage with ±20% tolerance, suitable for high‑voltage bulk energy storage needs within its rating.
• High Ripple Current Capability — Rated for 2.96 A at 120 Hz (low frequency) and 4.44 A at 50 kHz (high frequency), supporting sustained AC ripple under load.
• Endurance and Reliability — Designed to withstand 3,000 hours of DC bias plus rated ripple current at 85°C with capacitance remaining within ±20% of initial value and leakage current within initial specified limits.
• Loss Characteristics — Specified tan δ (loss tangent) of 0.15 at 20°C and 120 Hz for the 250 V rating, providing a defined dissipation characteristic for circuit design.
• Leakage Current — Rated leakage current of 1,350 µA as specified for this part, with series guidance on leakage behavior under rated voltage.
• Mechanical & Mounting — Snap‑in, radial can package (φ35 × 30 mm length) for secure board mounting; designed for tray packing to support production workflows.
• Environmental Range & Compliance — Operating temperature from –40°C to +85°C and RoHS compliant per series documentation.

Typical Applications

• General Purpose Power Systems — Bulk capacitance and smoothing in power supplies where a 250 V, high‑capacitance snap‑in solution is required.
• Industrial Electronics — Energy storage and ripple handling in industrial power modules that operate within –40°C to +85°C and require long service endurance.
• Board‑Level Snap‑in Installations — Applications needing a radial, snap‑in can for secure mounting and simplified assembly in production environments.

Unique Advantages

• High ripple tolerance: Explicit ripple ratings (2.96 A at 120 Hz, 4.44 A at 50 kHz) support designs with sustained AC loading.
• Long endurance under load: 3,000 hours at 85°C with rated ripple current ensures predictable performance over extended operating periods.
• Clear electrical characterization: Specified tan δ and leakage current values allow engineers to size and model dissipation and standby leakage accurately.
• RoHS compliant: Meets RoHS directive requirements as documented for the LLS series.
• Production‑ready packaging: Tray packing and mass production status facilitate repeatable procurement and assembly processes.
• Snap‑in mechanical retention: Radial can with snap‑in terminals provides secure board attachment for higher‑force or vibration‑tolerant assemblies.
