LLG2D122MELC25

The LLG2D122MELC25 is a Nichicon LLG series aluminum electrolytic capacitor in a snap-in terminal radial can. It provides 1.2 mF capacitance at a 200 V rating and is intended for general-purpose power applications where secure board mounting and compact packaging are required.

Designed one rank smaller than the LLS series to support equipment downsizing, this component delivers sustained performance across an operating range of –40 °C to +85 °C, with a specified endurance of 2000 hours at 85 °C. It is RoHS compliant.

Key Features

• Core Capacitance & Voltage: 1.2 mF (1200 μF) at 200 V for bulk energy storage and smoothing in DC power rails.
• Package & Mounting: Radial can with snap-in terminals provides secure, board-friendly mounting for through-hole power assemblies.
• Compact Size: Smaller case size compared to the LLS series to help reduce system footprint (size dimension L: 2.5 × D: 3.5 cm).
• Temperature Range & Endurance: Operating temperature –40 °C to +85 °C with a rated lifetime of 2000 hours at 85 °C under specified test conditions.
• Ripple Current Capability: Rated ripple current of 2.81 A at 120 Hz and 4.215 A at 100 kHz to support moderate AC ripple and switching environments.
• Electrical Characteristics: Capacitance tolerance ±20% (at 120 Hz, 20 °C); leakage current conforms to I ≤ 3√CV (μA) after 5 minutes at 20 °C; tan δ (max.) 0.15 at applicable rated voltages.
• Polarized Electrolytic: Polarized type suitable for DC applications requiring polarized bulk capacitance.
• Regulatory: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy storage on 200 V DC rails for regulated power modules and converters.
• Power Conversion: DC link and filtering in switched-mode power supplies and converters where ripple current handling is required.
• Compact Equipment Designs: Use in space-constrained power assemblies—one-rank smaller case size helps reduce overall system footprint.
• General-Purpose Electronics: Bulk capacitance and decoupling in instrumentation, control panels, and other general-purpose electronic equipment.

Unique Advantages

• Smaller Case, Same Functionality: One rank smaller than LLS-series cases to enable downsized equipment without sacrificing capacitance.
• Robust Ripple Handling: Specified ripple currents at both 120 Hz and 100 kHz to accommodate low- and high-frequency ripple in power systems.
• Designed for Long Operation at Elevated Temperature: 2000-hour endurance at 85 °C provides predictable aging and performance for sustained operation.
• Board-Retentive Snap-In Terminals: Snap-in mounting secures the capacitor for reliable mechanical and electrical connection in through-hole assemblies.
• Verifiable Electrical Limits: Leakage current defined by I ≤ 3√CV and tan δ maximum specified, enabling straightforward design validation and QA testing.
• RoHS Compliance: Meets applicable RoHS directives for regulatory compliance in commercial and industrial products.
