LLG2G151MELZ25

The LLG2G151MELZ25 is a Nichicon LLG series aluminum electrolytic capacitor in a snap‑in terminal configuration. It provides 150 µF capacitance at a 400 V rated voltage in a compact φ22 × 25 mm can designed for general‑purpose electrical designs.

Built for space‑conscious equipment, the LLG series offers a smaller case than comparable types and is RoHS compliant. The part is supplied in tray packing and is currently in mass production.

Key Features

• Core Electricals: 150 µF nominal capacitance with a tolerance of −20% to +20% and polarized construction for DC applications.
• Voltage Rating: 400 V rated voltage suitable where high DC voltage handling is required.
• Loss Characteristics: tanδ (DF) ≤ 0.15 measured at 20°C, 120 Hz, providing predictable dissipation characteristics under standard test conditions.
• Ripple Current Capability: Low‑frequency ripple current 1.03 A (120 Hz) and high‑frequency ripple current 1.473 A (100 kHz), specified for managing AC ripple in power circuits.
• Leakage Current: Specified leakage current of 730 µA, defined under rated conditions.
• Reliability & Lifetime: Endurance rated 2000 hours at 85°C with DC bias plus rated ripple current, meeting the LLG series endurance criteria when restored to 20°C.
• Thermal Range: Operating temperature range −25°C to +85°C for the 400 V variants in the series.
• Package & Mounting: Snap‑in terminal (radial, can – snap‑in) in a compact φ22 × 25 mm body; supplied in tray packing for production handling.
• Environmental Compliance: RoHS compliant per the LLG series declaration.

Typical Applications

• General‑purpose power modules: Useful in designs requiring a polarized aluminum electrolytic capacitor with 150 µF / 400 V ratings for general‑purpose DC circuits.
• Compact equipment designs: The LLG series provides a one‑rank smaller case size than LLS, making this part suited for equipment downsizing where board space is constrained.
• Snap‑in PCB assemblies: Snap‑in terminals enable secure insertion and mechanical stability for printed circuit board mounting in production environments.

Unique Advantages

• Compact high‑voltage solution: 150 µF at 400 V in a φ22 × 25 mm package helps conserve chassis and PCB space while maintaining voltage capability.
• Measurable ripple handling: Specified ripple current values at both 120 Hz and 100 kHz let designers assess thermal and ripple performance across frequency ranges.
• Clearly defined AC loss: tanδ specified at 0.15 (20°C, 120 Hz) for predictable dielectric loss under standard conditions.
• Long endurance at elevated temperature: 2000 hours at 85°C under rated conditions supports designs requiring sustained operation at elevated ambient temperatures.
• Production‑ready supply: Tray packing and mass production status support consistent manufacturing throughput and handling.
• Regulatory alignment: RoHS compliance supports deployment in products requiring restricted‑substance conformity.
