LLS2G101MELZ

The LLS2G101MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LLS series, designed for general‑purpose power applications. It delivers a 400 V rated voltage with 100 µF nominal capacitance in a compact φ22 × 25L radial can, offering a balance of high‑voltage capability, ripple handling and long endurance.

Engineered for systems that require reliable bulk energy storage and ripple suppression at elevated temperatures, this part is in mass production and RoHS compliant, making it suitable for procurement into production builds.

Key Features

• High voltage & capacitance — Rated at 400 V with 100 µF nominal capacitance and ±20% tolerance for bulk energy storage in high‑voltage circuits.
• Low loss characteristic — Tangent of loss angle (tan δ) specified at 0.15 max (20°C, 120 Hz), supporting efficient performance at the measurement frequency.
• Robust ripple current handling — 950 mA at 120 Hz (low frequency) and 1.359 A at 50 kHz (high frequency) to accommodate common AC ripple conditions.
• Controlled leakage — Leakage current specified at 600 µA, enabling predictable quiescent behavior.
• Endurance at elevated temperature — Designed to withstand 3000 hours at 85°C with rated ripple current applied, per LLS series endurance specification.
• Operating range & polarity — Polarized capacitor specified for operation from −25°C to +85°C.
• Package & mounting — Snap‑in radial can (φ22 × 25L) with tray packing for reliable board mounting and production handling.
• RoHS compliant — Meets RoHS directive requirements for lead‑free manufacturing environments.

Typical Applications

• High‑voltage power supplies — Bulk smoothing and energy storage in circuits operating up to 400 V DC where a polarized high‑voltage capacitor is required.
• Industrial power electronics — Ripple suppression and buffering in converter and inverter designs that expose capacitors to sustained ripple currents.
• General‑purpose power systems — Reliable polarized capacitance for a wide range of general‑purpose power designs needing a compact snap‑in solution.

Unique Advantages

• High‑voltage capability: 400 V rating enables use on higher DC buses without series stacking.
• Dual‑frequency ripple performance: Specified ripple current at both 120 Hz and 50 kHz allows designers to size for low‑ and high‑frequency ripple environments.
• Long endurance at temperature: 3000 hours at 85°C under rated ripple ensures predictable lifetime in elevated‑temperature applications.
• Predictable leakage behavior: 600 µA leakage current provides stable standby characteristics and easier thermal/power budgeting.
• Compact snap‑in form factor: φ22 × 25L radial can simplifies mechanical retention and board layout for through‑hole assemblies.
• RoHS compliance and mass production availability: Streamlines procurement and regulatory alignment for volume manufacturing.
