The LGA2W561MELB50 from Nichicon is a snap‑in, radial can aluminum electrolytic capacitor in the LGA series offering high capacitance and rated for 450 V. It is designed for general‑purpose applications that require high bulk capacitance, high ripple current handling and extended operational life at elevated temperature.

Key engineered attributes include 560 µF capacitance, operation across −40 °C to 105 °C, and endurance proven to withstand 5000 hours of rated ripple current at 105 °C. The part is RoHS‑compliant and supplied in a snap‑in mounting style for board installation.

Key Features

• High Capacitance: 560 µF nominal capacitance for substantial bulk energy storage in high‑voltage circuits.
• 450 V Rated Voltage: Rated for 450 V operation to support high‑voltage smoothing and decoupling use cases.
• High Ripple Current Capability: Rated ripple current of 3.18 A at 120 Hz (105 °C); effective ripple rises with frequency (e.g., ~4.55 A at 50 kHz based on frequency coefficient).
• Long Life at Elevated Temperature: Endurance specification: withstands 5000 hours application of rated ripple current at 105 °C with defined limits on capacitance change, tan δ and leakage current.
• Wide Operating Temperature Range: Specified for −40 °C to 105 °C to cover a broad range of operating environments.
• Leakage Current and Loss Characteristics: Leakage current specified as I ≤ 3√CV (μA) after 5 minutes at 20 °C; tan δ ≤ 0.20 (120 Hz, 20 °C).
• Snap‑In Radial Can Package: Snap‑in terminal type and radial can package for straightforward board mounting; size approximately 30 × 50 mm (L: 5 × D: 3 cm).
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply smoothing and bulk filtering: High capacitance and rated ripple current make this part suitable for smoothing high‑voltage rails and providing bulk energy storage.
• High‑voltage DC link support: 450 V rating and 560 µF capacitance provide substantial DC link capacitance where elevated voltage and ripple endurance are required.
• Industrial and general‑purpose electronics: Designed for demanding general‑purpose use where extended life at 105 °C and reliable ripple handling are necessary.

Unique Advantages

• Proven long‑life endurance: Endurance tested to 5000 hours at 105 °C under rated ripple current, providing predictable performance retention over time.
• High ripple handling with frequency scaling: Rated ripple current at 120 Hz is 3.18 A and increases with frequency (frequency coefficients provided), enabling designers to assess ripple performance across operating frequencies.
• Clear electrical limits and stability data: Datasheet defines leakage current, tan δ limits, impedance stability at low temperature and endurance/shelf‑life criteria for reliable design validation.
• Board‑friendly snap‑in mounting: Snap‑in radial can simplifies installation into through‑hole PCBs while providing robust mechanical and electrical connection.
• RoHS compliance: Meets RoHS directive requirements for conservation of restricted substances in finished assemblies.
