LAS2G151MELZ35ZB

The LAS2G151MELZ35ZB is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 150 µF capacitance at a 400 V rating in a compact φ22 × 35 mm can, optimized for equipment exposed to voltage fluctuation and continuous ripple stress.

Built for sustained operation up to 105°C with a rated endurance of 2000 hours at that temperature, this part combines high voltage capability, measurable high‑frequency ripple performance, and RoHS compliance for reliable performance in demanding commercial and industrial equipment.

Key Features

• Core Type Snap‑in terminal aluminum electrolytic capacitor, radial can package suitable for board‑level bulk capacitance.
• Electrical Rating 150 µF nominal capacitance with ±20% tolerance and a 400 V rated DC voltage.
• High Temperature Endurance Rated for operation from −25°C to +105°C with an endurance specification of 2000 hours at 105°C under rated ripple and DC bias.
• Ripple Current Performance Low‑frequency ripple current of 880 mA at 120 Hz and high‑frequency ripple capability of 1.012 A at 10 kHz, supporting both mains‑frequency and higher‑frequency smoothing.
• Leakage and Dissipation Specified leakage current of 730 µA and a tangent of loss angle (tan δ) of 0.20 (max) measured at 20°C, 120 Hz.
• Compact Can Package φ22 × 35 mm can size with snap‑in mounting for secure board retention and high current handling.
• Safety & Robustness Designed with improved safety features for abnormally excessive voltages and a pressure relief vent that operates without creating dangerous conditions.
• Regulatory Compliance RoHS compliant as declared in the product data.

Typical Applications

• Power supply smoothing — Bulk filtering and energy storage in high‑voltage DC power supplies where 400 V rating and sustained ripple handling are required.
• Industrial equipment — Filtering and decoupling in equipment subject to temperature up to 105°C and voltage fluctuation, leveraging the 2000 h endurance at elevated temperature.
• Voltage‑fluctuating environments — Applications that demand capacitors with improved safety features and tolerance to abnormal voltage conditions.

Unique Advantages

• High voltage capability: 400 V rated voltage supports higher‑voltage DC systems without overspecifying extra components.
• Long endurance at elevated temperature: 2000 hours at 105°C under rated conditions provides predictable life in hot operating environments.
• Broad ripple bandwidth: Specified ripple currents at 120 Hz and 10 kHz enable use across mains‑frequency and higher‑frequency converter stages.
• Compact snap‑in form factor: φ22 × 35 mm can and snap‑in terminals simplify board integration while supporting high current flow.
• Measured electrical stability: Capacitance tolerance of ±20% and tan δ ≤ 0.20 (120 Hz, 20°C) allow for predictable filter design and impedance budgeting.
• Safety‑oriented design: Pressure relief vent and enhanced protection against abnormal voltage events improve operational safety.
