LLG2E122MELB40

The LLG2E122MELB40 is an aluminum electrolytic capacitor in Nichicon’s LLG series, featuring a snap‑in terminal radial can designed for general‑purpose use. It delivers 1.2 mF capacitance at a 250 V rating and is intended for equipment designs that require reliable bulk capacitance in a reduced package footprint.

As part of the LLG family, this part is one rank smaller in case size than the LLS series and is explicitly suited for equipment downsizing. The device is RoHS compliant and built for standard industrial operating conditions.

Key Features

• Capacitance & Voltage — 1.2 mF nominal capacitance with a 250 V rated voltage, suitable for general‑purpose bulk energy storage and smoothing.
• Snap‑in Radial Package — Radial, can type with snap‑in terminals for robust mounting and simplified PCB installation.
• Compact Footprint — One rank smaller case size than LLS, aiding equipment downsizing while maintaining capacitance.
• Operating Temperature — Specified for −40 °C to +85 °C operation, aligned with the LLG series’ 85 °C category temperature.
• Endurance — Rated lifetime of 2000 hours at 85 °C under DC bias plus rated ripple conditions, with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Ripple Current Capability — Handles 3.84 A at 120 Hz and 5.76 A at 100 kHz, enabling effective performance in applications with significant AC ripple.
• Tolerance & Polarity — Capacitor is polarized with a capacitance tolerance of −20% to +20%.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Dimensions — Size listed as L: 4 × D: 3 cm, provided for mechanical planning and board layout considerations.

Typical Applications

• General Purpose Power Electronics — Provides bulk capacitance for smoothing and energy storage at 250 V in a wide range of general‑purpose equipment.
• Compact / Downsized Equipment — The smaller case size relative to LLS makes it suitable where board space and enclosure volume are constrained.
• High‑ripple Power Circuits — Designed to handle specified ripple currents at both low (120 Hz) and high (100 kHz) frequencies, useful for circuits with substantial ripple components.

Unique Advantages

• Space‑saving form factor — One rank smaller case than LLS enables designers to retain capacitance while reducing overall equipment size.
• Robust ripple handling — Specified ripple current ratings at 120 Hz and 100 kHz support reliable operation in ripple‑laden power circuits.
• Proven endurance at elevated temperature — 2000 hours at 85 °C endurance specification provides predictable aging characteristics for design planning.
• Snap‑in mounting — Snap‑in terminals simplify assembly and provide a secure mechanical connection for through‑hole boards.
• Regulatory compliance — RoHS compliance supports use in regions and products that require restricted substance conformance.
• Clear electrical specification — Polarized device with defined tolerance (−20% to +20%) and leakage/tan δ performance for predictable circuit behavior.
