LAK2G151MELB30

The LAK2G151MELB30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAK series. It provides 150 µF capacitance at a 400 V rated voltage in a radial, can-style snap‑in package (φ30 × 30 mm).

Designed for high‑voltage, general‑purpose power applications, this capacitor offers extended voltage options (200 V, 400 V and 420 V), improved safety features for abnormal voltage conditions, and endurance for sustained ripple duty at elevated temperature.

Key Features

• Rated Capacitance and Tolerance — 150 µF nominal with ±20% tolerance at 120 Hz, 20°C.
• High Voltage Rating — 400 V rated voltage, with the LAK series offering extended voltage options including 200 V and 420 V.
• High‑Temperature Endurance — Specified to withstand 2000 hours of rated ripple current at 105°C when operated under DC bias plus rated ripple current.
• Ripple Current Capability — 700 mA at 120 Hz and 805 mA at 10 kHz, supporting bulk filtering and smoothing in high‑voltage power circuits.
• Operating Temperature Range — −25°C to +105°C to cover a wide range of industrial thermal conditions.
• Safety Performance — Improved safety features and a pressure‑relief vent design that operate under abnormal excessive voltage without producing flames or dangerous dispersion of case pieces.
• Leakage and Dissipation Characteristics — Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ ≤ 0.20 (120 Hz, 20°C).
• Package and Mounting — Radial, snap‑in can package (φ30 × 30 mm) for secure PCB mounting and robust mechanical retention.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies — Bulk filtering and smoothing in high‑voltage AC/DC and DC/DC power stages where robust ripple handling and high voltage rating are required.
• Motor drives and inverters — Energy storage and decoupling for intermediate DC links and power conversion circuits operating near 400 V.
• UPS and power conditioning — Support for backup power systems and voltage‑fluctuating environments thanks to extended voltage range and enhanced safety features.
• General‑purpose high‑voltage equipment — Use in industrial electronics and equipment deployed in areas with fluctuating supply voltages where long ripple endurance and safety under abnormal conditions matter.

Unique Advantages

• High ripple endurance at elevated temperature: Rated to endure 2000 hours of rated ripple current at 105°C, enabling reliable long‑term operation under sustained stress.
• Extended high‑voltage options: Part of a series offering 200 V, 400 V and 420 V ratings, simplifying selection for different system voltage requirements.
• Enhanced safety design: Pressure‑relief venting and improved protection against abnormal excessive voltage reduce risk of hazardous failure modes.
• Clear electrical characterization: Specified leakage current formula (I ≤ 3√CV µA) and tan δ limits allow predictable performance during design and validation.
• Snap‑in package for robust mounting: Radial snap‑in construction provides secure PCB retention for high‑vibration or high‑current assemblies.
• RoHS compliance: Conforms to current RoHS directives for use in regulated manufacturing environments.
