LLG2Z222MELB45

The LLG2Z222MELB45 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LLG series, offering 2200 µF capacitance at 180 V in a compact φ30×45L can. It is designed as a smaller-sized snap-in solution to support equipment downsizing while delivering bulk energy storage and filtering capability for general-purpose power applications.

Key electrical characteristics include high ripple current capability, defined endurance at elevated temperature, and predictable loss and leakage figures, making this part suitable for applications that require reliable DC smoothing and energy buffering in 180 V systems.

Key Features

• Capacitance & Rated Voltage — 2200 µF nominal capacitance with a rated voltage of 180 V and capacitance tolerance of ±20% (120 Hz, 20°C).
• High Ripple Current — Supports 4.3 A at 120 Hz (low frequency) and 6.45 A at 100 kHz (high frequency), enabling effective smoothing under significant AC ripple loads.
• Endurance at Elevated Temperature — Specified for 2000 hours at 85°C under DC bias plus rated ripple current, with limits on capacitance change, tan δ, and leakage current after test.
• Operating Temperature Range — Rated for –40°C to +85°C operation, suitable for a wide ambient range within its rated voltage class.
• Low Loss & Leakage — Maximum tan δ of 0.15 at 20°C, 120 Hz, and a measured leakage current of 1880 µA for this part, supporting predictable performance.
• Snap‑in Radial Can Package — φ30×45L radial snap-in can for secure mounting and compact footprint; supplied in tray packing for mass production procurement.
• RoHS Compliant — Conforms to applicable RoHS directives as specified in the LLG series documentation.

Typical Applications

• Industrial power supplies — Bulk energy storage and DC smoothing in 180 V power rails where high ripple handling and compact snap‑in packaging are required.
• Power conversion and DC–DC systems — Filtering and ripple suppression in converters that demand high ripple current capability and predictable loss characteristics.
• Equipment downsizing projects — Replacement or redesigns targeting reduced case size, leveraging the LLG series’ smaller-sized footprint compared to larger family variants.

Unique Advantages

• Compact snap‑in format: φ30×45L can and snap‑in terminals support secure mounting while saving board space for downsized equipment designs.
• High ripple endurance: Rated ripple currents of 4.3 A (120 Hz) and 6.45 A (100 kHz) allow robust smoothing under heavy AC ripple conditions.
• Defined high‑temperature life: 2000 hours endurance at 85°C under rated conditions provides predictable aging and reliability metrics for design planning.
• Predictable electrical behavior: Low tan δ (0.15 max at 20°C, 120 Hz) and specified leakage current support stable performance in power applications.
• Production-ready packaging: Tray packing and mass production availability simplify procurement and assembly for volume builds.
