LLS2C681MELZ

The LLS2C681MELZ from Nichicon is a snap‑in aluminum electrolytic capacitor in the LLS series, offering 680 µF capacitance at a 160 V rating. Optimized for general‑purpose power applications, it delivers sustained ripple handling and long endurance for designs that require robust bulk capacitance in a compact radial can.

Designed for board‑mounted snap‑in installation, this part combines a 3000‑hour endurance at 85°C with measured electrical characteristics (tan δ, leakage current and ripple current) that facilitate predictable performance in power supply filtering and energy storage roles.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance with a 160 V working voltage and a capacitance tolerance of ±20% at 20°C, 120 Hz.
• High Ripple Current Performance — Low‑frequency ripple current of 2.35 A (120 Hz) and high‑frequency ripple current of 3.525 A (50 kHz) to support active power filtering and smoothing under AC ripple stress.
• Endurance & Reliability — Specified for 3000 hours at 85°C with the ability to withstand rated ripple current during that period, providing stable capacitance, controlled tan δ and acceptable leakage over life.
• Loss & Leakage Characteristics — Loss tangent (tan δ) of 0.15 (measured at 20°C, 120 Hz) and a measured leakage current of 980 µA for predictable dissipation and standby behavior.
• Package & Mounting — Radial, snap‑in can (φ22 × 35 mm L) in tray packing for reliable mechanical retention and efficient assembly.
• Temperature Range & Compliance — Operating temperature range from −40°C to +85°C and RoHS‑compliant construction.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple attenuation where 160 V blocking voltage and multi‑amp ripple capability are required.
• Energy storage for industrial electronics — Short‑term energy buffering and decoupling in general‑purpose power systems operating within −40°C to +85°C.
• Board‑mounted power modules — Snap‑in mounting for secure mechanical retention and space‑efficient bulk capacitance on power conversion boards.

Unique Advantages

• Proven endurance specification — Rated 3000 hours at 85°C with applied rated ripple current, offering long life under continuous thermal and electrical stress.
• Quantified ripple capability — Explicit low‑ and high‑frequency ripple current ratings (2.35 A at 120 Hz, 3.525 A at 50 kHz) allow designers to match the capacitor to application ripple profiles.
• Predictable electrical behavior — Measured tan δ (0.15 at 20°C, 120 Hz) and specified leakage current (980 µA) provide clear parameters for thermal and standby loss budgeting.
• Secure snap‑in mounting — Radial snap‑in can package simplifies board retention for heavy‑duty power components and high‑vibration environments.
• RoHS‑compliant — Conforms to environmental requirements for regulated materials.
• Production readiness — Product is in mass production and supplied in tray packing for efficient handling.
