LAS2G121MELZ30ZB

The LAS2G121MELZ30ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAS series designed for general‑purpose power applications. It delivers 120 µF at a 400 V rating with a 105 °C operating temperature limit and a 2000‑hour endurance at 105 °C.

Engineered for reliable high‑voltage operation, this radial can, snap‑in package combines compact dimensions (φ22 × 30 L / L: 3 × D: 2.2 cm) with robust ripple handling and low leakage characteristics, making it suitable for equipment exposed to voltage fluctuation and demanding thermal conditions.

Key Features

• Core Electricals — 120 µF capacitance at 400 V with ±20% tolerance, polarized design for high‑voltage DC applications.
• High‑Temperature Endurance — Rated to operate from −25 °C to +105 °C with a guaranteed 2000 hours endurance at 105 °C under rated conditions.
• Ripple Current Capability — 760 mA at 120 Hz (low frequency) and 874 mA at 10 kHz (high frequency), with frequency coefficient data available for elevated frequencies.
• Low Loss and Leakage — Maximum tan δ of 0.20 (120 Hz, 20 °C) and leakage current specified at 650 µA to help minimize standby and loss currents in the system.
• Package & Mounting — Radial, snap‑in can (snap‑in terminals) in a compact φ22 × 30 L package for board‑level installation; supplied in tray packing and offered in mass production.
• Safety & Stability — LAS series design includes improved safety features for abnormally excessive voltage and stable performance after long‑term ripple/current application.
• Regulatory — RoHS compliant.

Typical Applications

• General‑purpose power designs — Provides a 400 V, 120 µF option for general‑purpose DC applications requiring a high‑voltage snap‑in capacitor.
• Equipment in voltage‑fluctuating environments — LAS series safety features and voltage tolerance are suitable for use in equipment exposed to abnormal or fluctuating voltage conditions.
• High‑temperature installations — Rated to 105 °C with 2000‑hour endurance, appropriate where elevated ambient temperatures are expected.
• Board‑level retrofit or replacement — Compact φ22 × 30 L radial snap‑in package fits applications needing a space‑efficient, high‑voltage electrolytic solution.

Unique Advantages

• Long‑term thermal reliability: 2000‑hour endurance at 105 °C ensures sustained performance under prolonged high‑temperature operating conditions.
• Strong ripple handling: Specified ripple currents of 760 mA (120 Hz) and 874 mA (10 kHz) support designs with significant AC ripple loads.
• Compact snap‑in form factor: φ22 × 30 L radial can with snap‑in terminals simplifies board mounting while conserving PCB space.
• Low loss and controlled leakage: tan δ ≤ 0.20 and leakage current around 650 µA reduce dissipation and standby losses in the system.
• Designed for abnormal voltage resilience: LAS series includes enhanced safety measures for operation in voltage‑fluctuating conditions.
• RoHS compliant and mass production available: Environmentally compliant manufacturing and tray packing for production volumes.
