LLG2C122MELZ40

The LLG2C122MELZ40 is a Nichicon LLG series aluminum electrolytic capacitor in a snap-in terminal, radial can package. It provides 1.2 mF capacitance at a 160 V rating and is designed for general-purpose electronic equipment where a smaller case size is required.

Part of the LLG family, this snap-in type is one rank smaller than the LLS series and is suited for equipment downsizing. It is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) rated at 160 V DC, providing bulk capacitance for power systems and general-purpose applications.
• Tolerance & Polarization — Capacitance tolerance ±20% at 120 Hz, 20°C; polarized capacitor for DC applications.
• Ripple Current Handling — Rated ripple current of 3.05 A at 120 Hz and 4.575 A at 100 kHz to support AC ripple on DC bias.
• Operating Temperature & Endurance — Category temperature range includes –40°C to +85°C for the 160 V rating and endurance specified as 2000 hours at 85°C under rated DC bias plus ripple current.
• Leakage & Dissipation — Leakage current defined by I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) spec applies for quality assurance.
• Package & Mounting — Snap-in terminal type in a radial can package for secure PCB mounting in assemblies that accept snap-in components.
• Compact Footprint — Smaller case sizing compared to LLS models to help reduce PCB area in downsized equipment; physical size documented as L: 4 × D: 2.2 cm.
• RoHS Compliance — Complies with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics — Bulk capacitance for a wide range of general-purpose electronic equipment requiring polarized aluminum electrolytic capacitors.
• Equipment Downsizing — Suited for designs where a smaller case size is needed; one rank smaller than LLS to help reduce overall equipment footprint.
• Snap-in PCB Assemblies — Designed for assemblies that use snap-in radial can mounting for reliable board installation.

Unique Advantages

• Space-efficient form factor: One rank smaller case size than LLS and a compact L: 4 × D: 2.2 cm footprint to aid equipment downsizing.
• High-voltage capability: 160 V rating provides margin for mid-voltage power rails and DC bus applications.
• Measured ripple handling: Explicit ripple ratings of 3.05 A (120 Hz) and 4.575 A (100 kHz) allow designers to match the part to expected ripple load conditions.
• Proven endurance at elevated temperature: Endurance specified as 2000 hours at 85°C under rated DC bias plus ripple current, supporting predictable lifetime planning.
• Defined leakage and loss specifications: Leakage current and tan δ limits (including leakage formula I ≤ 3√CV) provide verifiable electrical characteristics for quality control.
• Regulatory compliance: RoHS compliance (2011/65/EU, (EU)2015/863) supports deployment in regulated markets.
