LLG2C561MELZ25

The LLG2C561MELZ25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LLG series. It delivers 560 µF capacitance at a 160 V rating in a compact, snap‑in can designed for equipment downsizing and general‑purpose power applications.

Key value comes from a small case size (one rank smaller than LLS), robust ripple handling, and specified endurance at elevated temperature, making it suitable for designs that require compact bulk capacitance with rated performance across −40 °C to +85 °C.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a 160 V rated voltage and ±20% tolerance, specified at 120 Hz, 20 °C.
• Compact Snap‑in Package — Radial, snap‑in can with size 22 × 25 mm (φD × L) and a seated height maximum of 2.5 cm, enabling equipment downsizing compared with LLS series.
• Ripple Current Capability — Rated ripple current of 2.25 A at 120 Hz and 3.375 A at 100 kHz, supporting AC ripple filtering and bulk energy tasks.
• Temperature Range & Endurance — Operating temperature −40 °C to +85 °C with an endurance rating of 2000 hours at 85 °C under DC bias plus rated ripple current; capacitance change within ±20% after endurance test per the datasheet.
• Leakage & Loss Characteristics — Leakage current meets I ≤ 3√(C·V) µA after 5 minutes at 20 °C; tangent of loss angle (tan δ) max 0.15 for 160 V rating (measurement at 120 Hz, 20 °C).
• Low‑temperature Stability — Impedance stability specified with Z(−25 °C)/Z(+20 °C) ≤ 4 for the 160 V range, aiding low‑temperature performance assessment.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling in general‑purpose electronic equipment that requires 560 µF at 160 V.
• Compact power supplies — Used where equipment downsizing is a priority; the LLG series is one rank smaller than LLS, helping reduce PCB footprint while providing rated bulk capacitance.
• Snap‑in PCB assemblies — Snap‑in terminal mounting for secure through‑hole retention in assemblies requiring robust mechanical stability.

Unique Advantages

• Smaller case for space savings: One rank smaller case than LLS enables more compact power designs without changing rated capacitance or voltage.
• High voltage bulk capacitance: 560 µF at 160 V supports applications needing substantial energy storage at elevated DC voltage levels.
• Measured ripple performance: Specified ripple ratings at both 120 Hz (2.25 A) and 100 kHz (3.375 A) provide clear guidance for AC ripple handling in design calculations.
• Documented endurance and recovery: Endurance of 2000 hours at 85 °C with defined recovery limits (capacitance within ±20%, tan δ ≤ 200% of initial, leakage ≤ initial) offers verifiable reliability metrics.
• Leakage current specification: Leakage current bounded by I ≤ 3√(C·V) µA after initial application of rated voltage, enabling predictable standby and loss estimates.
• Low‑temperature impedance data: Z(−25 °C)/Z(+20 °C) ≤ 4 for 160 V provides a quantified view of low‑temperature behavior for designers.
