LLG2Z681MELZ30

The LLG2Z681MELZ30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LLG series, offering 680 µF nominal capacitance at 180 V. It delivers high bulk capacitance in a reduced case size—one rank smaller than the LLS series—making it well suited for equipment downsizing while maintaining electrolytic performance.

Designed for general‑purpose use, the LLG2Z681MELZ30 provides polarized, snap‑in mounting in a radial can package and is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage: 680 µF rated capacitance at 180 V for bulk energy storage and smoothing.
• Compact Snap‑In Package: Radial, can snap‑in termination sized 22 × 30 mm (L × D, 3.0 × 2.2 cm) to support equipment miniaturization; one rank smaller case than LLS.
• Operating Temperature & Lifetime: Rated for –40°C to +85°C with endurance specified as 2000 hours at 85°C under DC bias plus rated ripple current.
• Ripple Current Capability: 1.9 A at 120 Hz and 2.85 A at 100 kHz to support AC ripple handling in power applications.
• Electrical Characteristics: Capacitance tolerance ±20%; tan δ (max.) 0.15 at 120 Hz, 20°C for rated voltages 160–400 V; leakage current governed by I ≤ 3√CV (μA) after 5 minutes at 20°C.
• Durability & Shelf Life: Endurance and shelf life defined in the datasheet: after 2000 hours at 85°C under specified conditions, capacitance change remains within ±20%, tan δ within 200% of initial, and leakage current does not exceed initial specified value. Shelf life condition: 1000 hours at 85°C followed by voltage treatment per JIS C 5101-4 clause 4.1.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Identification: Marked with white print on a black sleeve for easy identification.

Typical Applications

• Compact Power Supplies: Bulk energy storage and smoothing where a smaller capacitor case supports equipment downsizing efforts.
• General‑Purpose Industrial Electronics: DC link and filtering duties in industrial control equipment requiring robust polarized capacitance.
• Power Conversion Modules: Bulk and ripple handling in power modules that benefit from snap‑in mounting and defined ripple ratings at 120 Hz and 100 kHz.

Unique Advantages

• Reduced Footprint: One rank smaller case than LLS enables denser board layouts and contributes to equipment miniaturization.
• High Ripple Performance: Specified ripple current at both low and high frequencies helps maintain capacitor stability under AC stress.
• Defined Endurance: 2000 hours at 85°C under rated conditions provides a clear reliability expectation for thermal and electrical stress.
• Wide Temperature Range: –40°C to +85°C operating range supports deployments across varied ambient conditions.
• Traceable Electrical Limits: Tangent of loss angle and leakage current limits (including I ≤ 3√CV after 5 minutes) offer measurable acceptance criteria for design validation.
• RoHS Compliance: Conforms to applicable RoHS directives for environmental compliance in regulated markets.
