LLG2G561MELB40

The LLG2G561MELB40 is a polarized aluminum electrolytic capacitor from Nichicon's LLG series, featuring a 560 µF capacitance and a 400 V rated voltage in a snap-in radial can package. Designed as a smaller-sized LLG series device, it supports general-purpose applications that require a compact, high-voltage electrolytic solution.

Key value points include snap-in mounting for secure board attachment, a compact φ30 × 40 mm case size, RoHS compliance, and an endurance specification of 2000 hours at 85 °C under rated conditions—properties that make it suited for mass-production assemblies supplied in tray packing.

Key Features

• Electrical — 560 µF nominal capacitance with a tolerance of ±20% and a 400 V rated voltage; polarized construction for high-voltage general-purpose use.
• Package & Mounting — Snap-in terminal, radial can (snap-in) package in φ30 × 40 mm (L: 4 cm × D: 3 cm) form factor; tray packing for mass production. Maximum seated height: 1.575 inch.
• Temperature & Endurance — Operating temperature range of –25 °C to +85 °C (category rating for 400 V devices) with an endurance rating of 2000 hours at 85 °C when subjected to DC bias plus rated ripple current.
• Ripple Current — Rated ripple current of 2.39 A at 120 Hz and 3.418 A at 100 kHz for AC stress planning.
• Leakage & Loss Characteristics — Leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) maximum 0.15 for 160–400 V (measured at 120 Hz, 20 °C).
• Low-temperature Stability — Impedance ratio Z(–25 °C) / Z(+20 °C) maximum of 8 for 400 V parts, aiding performance expectations in lower-temperature operation.
• Regulatory & Identification — RoHS compliant; capacitors are marked with white lettering on a black sleeve for clear identification.

Typical Applications

• General-purpose electronic equipment — Suited to designs that require a 560 µF, 400 V polarized snap-in aluminum electrolytic capacitor in a compact LLG form factor.
• High-voltage power assemblies — Applicable where a 400 V rated electrolytic with specified ripple current capability and endurance is required for general-purpose use.
• Mass-production assemblies — Tray packing and snap-in mounting make the part appropriate for production lines requiring consistent handling and mechanical retention.

Unique Advantages

• Compact LLG sizing — One rank smaller case than LLS in the LLG series, helping reduce component footprint in space-constrained designs.
• High-voltage, high-capacitance combination — 560 µF at 400 V provides substantial capacitance in a 400 V-rated snap-in package for general-purpose applications.
• Defined endurance specification — 2000 hours at 85 °C under rated conditions provides a clear reliability expectation for thermal and electrical stress planning.
• Measured electrical limits — Explicit leakage current formula (I ≤ 3√CV) and tan δ maximum (0.15 at 400 V) let engineers design with verifiable electrical limits.
• Production-ready packaging — Tray packing and snap-in terminals streamline assembly for high-volume manufacturing.
• RoHS compliant — Conforms to RoHS directive requirements for restricted substances.
