LLS2Z182MELB

The LLS2Z182MELB is an aluminum electrolytic capacitor from Nichicon’s LLS series featuring a snap‑in terminal package and 85°C standard rating. It provides 1800 µF capacitance at a 180 V rating with polarized construction and is manufactured for general‑purpose applications.

Designed for applications that require high ripple current handling and extended endurance, this snap‑in can supports prolonged operation with a 3000‑hour life at 85°C while delivering low dissipation factor and defined leakage characteristics.

Key Features

• Capacitance & Voltage: 1.8 mF (1800 µF) rated at 180 V with ±20% tolerance for predictable energy storage and bulk decoupling.
• Snap‑in Package: Radial, can snap‑in termination designed for through‑hole mounting; physical size φ30 × 45L (L: 4.5 × D: 3 cm) for compact board placement.
• Endurance & Temperature: Rated for 3000 hours at 85°C; operating temperature range −40°C to 85°C for sustained performance across typical industrial environments.
• High Ripple Current Capability: 4.55 A at 120 Hz (low frequency) and 6.825 A at 50 kHz (high frequency) to support applications with substantial AC ripple stress.
• Electrical Loss & Leakage: Tanδ (DF) 0.15 max at 20°C and 120 Hz; specified leakage current 1700 µA for predictable dissipation and startup behavior.
• Reliability & Compliance: Withstanding rated ripple for 3000 hours at 85°C and RoHS‑compliant construction; available in tray packing and currently in mass production.
• Polarized Design: Polar capacitor suitable for DC bus and smoothing applications where polarity is observed.

Typical Applications

• Power supply filtering: Bulk decoupling and smoothing in power conversion circuitry that requires 1800 µF at 180 V and high ripple current handling.
• Industrial electronics: General‑purpose energy storage and ripple mitigation in industrial control and power modules operating within −40°C to 85°C.
• DC bus and energy buffering: DC link smoothing where sustained ripple endurance and defined leakage characteristics are necessary.

Unique Advantages

• High ripple tolerance: Specified low‑ and high‑frequency ripple currents (4.55 A @120 Hz, 6.825 A @50 kHz) support demanding AC stress profiles.
• Long endurance: Rated to withstand 3000 hours at 85°C with defined post‑test limits on capacitance, tanδ and leakage for predictable lifecycle performance.
• Compact snap‑in form factor: φ30×45L package offers a space‑efficient through‑hole solution with robust mechanical retention.
• Controlled loss characteristics: Tanδ of 0.15 at 20°C and 120 Hz provides low dissipation for improved thermal stability under load.
• RoHS compliant & production ready: Meets RoHS requirements and is available in tray packing for streamlined procurement and assembly.
