LLS2A122MELZ

The LLS2A122MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LLS series, rated 1.2 mF (1200 µF) at 100 V with ±20% tolerance. It is a general‑purpose, radial can (snap‑in) package designed for applications requiring high capacitance, elevated ripple handling and long endurance at up to 85°C.

Key value propositions include robust ripple current capability at both low and high frequencies, a low dissipation factor (tan δ = 0.20 at 20°C/120 Hz), RoHS compliance, and a 3000‑hour endurance rating at 85°C for sustained performance in continuous‑use environments.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a 100 V rated voltage and ±20% tolerance.
• Terminal & Package — Snap‑in terminal type in a radial, can snap‑in package (size φ22 × 30 mm length) for secure mechanical mounting.
• Endurance — Rated for 3000 hours at 85°C with DC bias plus rated ripple current applied, meeting the LLS series endurance specification.
• Ripple Current Performance — 2120 mA at 120 Hz (low frequency) and 2438 mA at 50 kHz (high frequency) for improved ripple handling across a range of operating frequencies.
• Low Loss — Dissipation factor (tan δ) of 0.20 maximum at 20°C and 120 Hz (rated voltage 100 V), supporting lower AC loss in filtering applications.
• Leakage Current — Specified leakage current of 1030 µA (measured conditions shown in product data).
• Operating Temperature — −40°C to +85°C operating range for broad environmental compatibility.
• Compliance & Packaging — RoHS‑compliant and supplied in tray packing; product is in mass production status.

Typical Applications

• General Purpose — Use where a 1.2 mF, 100 V electrolytic capacitor is required and a snap‑in mounting is preferred for secure board attachment.
• High‑ripple Environments — Suited to circuits that require substantial ripple current handling at both 120 Hz and higher frequencies (spec'd ripple currents: 2.12 A at 120 Hz, 2.438 A at 50 kHz).
• Elevated‑temperature Service — Designed for continuous operation up to 85°C with a 3000‑hour endurance rating for sustained reliability.

Unique Advantages

• High voltage capability: 100 V rating enables use in higher‑voltage circuits where standard low‑voltage electrolytics are insufficient.
• Strong ripple performance: Specified ripple currents at both low and high frequencies provide flexibility across filter and smoothing applications.
• Long endurance at temperature: 3000 hours at 85°C ensures stability of capacitance, tan δ and leakage current after extended operation.
• Low dissipation factor: tan δ = 0.20 (20°C/120 Hz) minimizes AC losses and heat generation under ripple conditions.
• Rugged snap‑in mounting: Radial snap‑in package provides reliable mechanical retention in assemblies and straightforward assembly handling.
• RoHS‑compliant and production‑ready: Tray packing and mass production status simplify procurement and production planning.
