LLS2C681MELB

The LLS2C681MELB is an aluminum electrolytic, snap‑in terminal capacitor in Nichicon’s LLS series designed for general‑purpose electronic equipment. It delivers 680 µF capacitance at a 160 V rating in a radial, snap‑in can package suited to through‑hole assemblies.

Key value comes from its combination of high voltage capability, low loss (tan δ), robust ripple current ratings across low and high frequencies, and a demonstrated 3000‑hour endurance at 85°C for reliable bulk energy storage and smoothing in general‑purpose designs.

Key Features

• Capacitance & Voltage — 680 µF capacitance rated at 160 V for higher‑voltage bulk energy applications.
• Tolerance — ±20% capacitance tolerance at 120 Hz, 20°C for predictable sizing in designs.
• Low Loss — tan δ = 0.15 (max.) measured at 20°C, 120 Hz for the 160 V rating, minimizing dissipation in AC conditions.
• Ripple Current Capability — 2.33 A at 120 Hz (low frequency) and 3.495 A at 50 kHz (high frequency) to support smoothing under varying ripple conditions.
• Leakage Current — Specified leakage current of 980 µA after voltage application, enabling predictable standby behavior.
• Durability & Life — Endurance of 3000 hours at 85°C when subjected to rated DC bias plus rated ripple current, meeting the LLS series endurance criteria.
• Mechanical & Mounting — Snap‑in terminal, radial can (φ30 × 25 mm), designed for secure through‑hole mounting and board retention.
• Operating Range — Rated for operation from −40°C to +85°C in accordance with series category temperature limits.
• RoHS Compliant — Meets RoHS requirements for lead‑free material compliance.

Typical Applications

• General‑Purpose Electronic Equipment — Bulk capacitance and smoothing in a wide range of electronic systems where a radial, snap‑in electrolytic capacitor is appropriate.
• Power Filtering — Use in circuits requiring DC bias handling up to 160 V with specified ripple current capability at both low and high frequencies.
• Industrial and Assembly‑Level Builds — Through‑hole snap‑in package facilitates secure mounting and mechanical retention for mass production assemblies.

Unique Advantages

• High Voltage Handling: 160 V rated voltage supports higher DC bus applications without series stacking.
• Measured Low Loss: 0.15 tan δ (max.) at 20°C, 120 Hz for the 160 V rating, reducing internal heat generation under AC ripple.
• Wide Ripple Current Range: Distinct low‑ and high‑frequency ripple current specifications (2.33 A @ 120 Hz; 3.495 A @ 50 kHz) provide predictable performance across switching and line‑frequency environments.
• Proven Endurance: Rated for 3000 hours at 85°C with applied rated ripple and DC bias, supporting long operational life in elevated ambient conditions.
• Secure Snap‑in Mounting: Radial, can‑type snap‑in package (φ30 × 25 mm) for reliable board retention in through‑hole assemblies and tray packing for production handling.
• Compliance: RoHS‑compliant construction for regulatory alignment in standard commercial and industrial applications.
