LLG2D122MELA40

The LLG2D122MELA40 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LLG series, designed as a one‑rank smaller case size than the LLS series to support equipment downsizing. It provides 1.2 mF capacitance at a 200 V rating and is intended for general‑purpose use in electronic equipment.

Key electrical and mechanical attributes include polarized aluminum electrolytic construction, snap‑in radial can package, RoHS compliance, an operating temperature range that supports –40 °C to +85 °C, and a defined 2000‑hour endurance at 85 °C under rated conditions.

Key Features

• Capacitance and Voltage — 1.2 mF nominal capacitance with a 200 V rated voltage and ±20% tolerance for bulk energy storage and smoothing in general‑purpose circuits.
• Snap‑in Radial Package — Radial, can snap‑in mounting for secure PCB retention and straightforward assembly in down‑sized equipment layouts.
• Temperature and Endurance — Rated for operation from –40 °C to +85 °C with a specified lifetime of 2000 hours at 85 °C when subjected to DC bias plus rated ripple current.
• Ripple Current Performance — Handles 2.81 A at 120 Hz and 4.215 A at 100 kHz (specified ripple current values) for AC ripple and high‑frequency applications within the rated limits.
• Leakage and Stability — Leakage current defined by I ≤ 3√CV (μA) after 5 minutes at 20 °C; endurance and shelf‑life limits require capacitance within ±20%, tan δ ≤ 200% of initial spec, and leakage current ≤ initial specified value after conditioning.
• RoHS Compliance and Marking — Compliant with RoHS directives (2011/65/EU, (EU)2015/863) and marked with white print on a black sleeve for clear identification.
• Polarized Construction — Polarized capacitor intended for DC bias applications where polarity is observed.

Typical Applications

• General‑Purpose Power Supplies — Bulk filtering and energy storage for power supply rails in commercial and industrial equipment.
• Power Conversion Modules — DC‑link and smoothing applications where a compact 1.2 mF / 200 V capacitor aids in equipment size reduction.
• Industrial and Commercial Electronics — General‑purpose decoupling, buffering, and ripple attenuation in equipment requiring reliable electrolytic capacitance.

Unique Advantages

• Compact Case for Downsized Designs — One rank smaller case size than the LLS series enables reduced PCB footprint and enclosure size without sacrificing bulk capacitance.
• High Rated Capacitance at 200 V — 1.2 mF nominal value at 200 V provides substantial energy storage for smoothing and buffering in DC circuits.
• Measured Ripple Handling — Specified ripple currents at 120 Hz and 100 kHz support predictable thermal and electrical behavior under AC superposition.
• Defined Endurance and Shelf Life — 2000 hours at 85 °C endurance and documented shelf‑life recovery requirements give clear expectations for long‑term performance.
• Regulatory Compliance — RoHS compliance simplifies material‑restriction management in product development and procurement.
• Robust Mounting — Snap‑in radial can provides secure mechanical retention for assemblies subject to handling and vibration within equipment specifications.
