LLS2C821MELA

The LLS2C821MELA is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It provides 820 µF capacitance at a 160 V rated voltage in a radial, can-style snap‑in package.

Engineered for sustained ripple handling and long endurance, this part targets power supply filtering and bulk energy storage in industrial and general‑purpose electronic equipment while offering RoHS compliance and tray packing for production use.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance with ±20% tolerance and a 160 V rated voltage for higher‑voltage power rails.
• Ripple Current & Loss: Rated ripple current of 2.65 A at 120 Hz and 3.975 A at 50 kHz; tangent of loss angle (tan δ) specified at 0.15 (20 °C, 120 Hz) for predictable dissipation characteristics.
• Leakage Current: Specified leakage current of 1080 µA, measured per product test conditions.
• Endurance & Reliability: Designed to withstand 3000 hours of rated ripple current at 85 °C with defined limits: capacitance change within ±20%, tan δ ≤ 200% of the initial specification, and leakage current at or below initial specified value after test.
• Temperature Performance: Operating temperature range from −40 °C to +85 °C; low‑temperature impedance behavior for the 160–250 V range is specified (Z(−25 °C)/Z(+20 °C) ≤ 3; Z(−40 °C)/Z(+20 °C) ≤ 12).
• Package & Mounting: Snap‑in terminal, radial can package (φ25 × 30L / L: 3 cm × D: 2.5 cm) suitable for secure PCB mounting; supplied in tray packing and available in mass production.
• Compliance: RoHS‑compliant construction.

Typical Applications

• General‑purpose power filtering: Bulk capacitance and ripple handling for smoothing and decoupling on higher‑voltage rails where 160 V rating is required.
• Power supply energy storage: Use in switch‑mode and linear power supplies to support transient energy demands and maintain rail stability.
• Industrial electronics: Applications that require robust endurance at elevated temperature (85 °C) and consistent long‑term performance under rated ripple current.

Unique Advantages

• High ripple capability: Dual ripple ratings (2.65 A at 120 Hz and 3.975 A at 50 kHz) enable reliable operation across low and high frequency power domains.
• Long endurance verified: 3000‑hour endurance at 85 °C with defined post‑test limits provides predictable life characteristics for design planning.
• Voltage headroom: 160 V rating supports designs requiring elevated DC bus capability without series stacking.
• Stable dissipation behavior: tan δ specified at 0.15 (20 °C, 120 Hz) provides a measurable baseline for thermal and loss budgeting.
• Snap‑in package for secure mounting: Radial can snap‑in termination simplifies mechanical retention and assembly in production environments.
• RoHS compliance and mass production availability: Environmentally compliant and supplied in tray packaging for consistent production workflows.
