LAS2G151MELB25

The LAS2G151MELB25 is a snap‑in terminal aluminum electrolytic capacitor rated at 150 µF and 400 V, offered in a compact radial can (φ30×25 mm). It is a general‑purpose power capacitor designed for equipment operating in environments with voltage fluctuations.

Key value propositions include a 105 °C endurance with 2,000 hours of rated ripple current capability, a smaller case size with higher ripple handling than the LAQ series, and enhanced safety features to mitigate abnormal overvoltage events. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High-Temperature Endurance — Specified for operation from −25 °C to +105 °C and guaranteed for 2,000 hours under rated ripple current at 105 °C.
• Ripple Current Performance — Rated ripple current of 880 mA at 120 Hz and 1.012 A at 10 kHz; frequency coefficient increases from 0.88 at 50 Hz to 1.15 at 10 kHz or more.
• Snap‑In Radial Can Package — Snap‑in terminal, radial can package for secure board mounting and robust mechanical retention.
• Safety Features — Improved safety design for abnormally excessive voltage, including a pressure relief vent that operates without producing dangerous conditions.
• Leakage and Dissipation — Leakage current and tan δ meet the series specifications (leakage: 1 ≤ 3√C µA after 5 minutes at 20 °C; tan δ ≤ 0.20 at 120 Hz, 20 °C).

Typical Applications

• Power electronics in fluctuating-voltage environments — Suited for equipment operating where supply voltages vary, leveraging the series’ enhanced safety and endurance.
• General-purpose industrial equipment — Use where long high-temperature life (2,000 hours at 105 °C) and elevated ripple current capability are required.
• Boards requiring secure mounting — Snap-in radial can package provides reliable mechanical retention for assemblies exposed to vibration or handling.

Unique Advantages

• Long high-temperature life: 2,000 hours at 105 °C under rated ripple current supports sustained operation in hot environments.
• Elevated ripple handling: Higher ripple current capability (880 mA at 120 Hz; 1.012 A at 10 kHz) improves performance in power filtering and smoothing roles.
• Compact footprint: Smaller case size than the LAQ series enables tighter board layouts while maintaining performance.
• Improved overvoltage safety: Built-in safety features and a pressure relief vent reduce risk during abnormal voltage conditions.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
