LLS2E821MELB

The LLS2E821MELB is an aluminum electrolytic, snap‑in terminal capacitor designed for general‑purpose electronic equipment. It combines a 250 V rated voltage with 820 µF capacitance in a radial, snap‑in can package to support power‑stage filtering and bulk energy storage needs.

Engineered for sustained ripple duty, the part delivers specified low‑ and high‑frequency ripple current capability with a 3000‑hour endurance at 85°C, offering a reliable solution for designs that require long operational life under applied ripple current.

Key Features

• Capacitance & Tolerance — 820 µF with ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk smoothing and decoupling tasks.
• Rated Voltage — 250 V DC rating for higher‑voltage power rails and intermediate DC links.
• Snap‑in Terminal Package — Radial, can‑type snap‑in mounting for secure mechanical retention in PCB power assemblies; supplied in tray packing for production handling.
• Ripple Current Capability — 2.98 A at 120 Hz (low frequency) and 4.47 A at 50 kHz (high frequency), supporting continuous ripple loading within specified limits.
• Leakage & Dissipation — Specified leakage current of 1350 µA and tangent of loss angle (tan δ) of 0.15 at 20°C/120 Hz for predictable electrical behavior in DC‑biased applications.
• Endurance & Temperature Range — Withstands 3000 hours at 85°C under rated ripple/current conditions; operating temperature range −40°C to +85°C.
• Form Factor — Physical size φ30 × 35 mm (L: 3.5 cm × D: 3.0 cm) providing a compact footprint for high‑voltage, high‑capacitance requirements.
• Compliance & Production Status — RoHS compliant and available in mass production quantities.

Typical Applications

• General‑purpose electronic equipment — Use where a 250 V, 820 µF polarized capacitor is required for bulk smoothing and energy buffering.
• Power supply filtering — Suitable for DC bus smoothing and ripple management given its rated ripple current and endurance at 85°C.
• High‑voltage power stages — Appropriate for applications that require a compact, high‑voltage electrolytic solution in a snap‑in package.

Unique Advantages

• High ripple‑current handling: Rated ripple currents of 2.98 A (120 Hz) and 4.47 A (50 kHz) allow sustained operation under AC ripple loads common in power electronics.
• Long operational endurance: Rated to withstand 3000 hours at 85°C with applied ripple and DC bias, supporting longer service life in demanding thermal conditions.
• Low dissipation at 120 Hz: tan δ of 0.15 at 20°C/120 Hz for the 250 V rating, enabling predictable loss behavior in filtering applications.
• Compact, secure mounting: Snap‑in radial can design simplifies mechanical retention on the board while keeping a small footprint for high‑voltage capacitance.
• RoHS compliant and production ready: Conforms to RoHS requirements and is available in tray packing for streamlined assembly and procurement.
