LAQ2G101MELA25ZB

The LAQ2G101MELA25ZB is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose electronic applications that require a compact, high‑voltage smoothing element. This radial, can‑style capacitor delivers 100 µF at a 400 V rated voltage in a 25 × 25 mm package and is offered in tray packing for mass production.

Engineered for continuous operation up to 105°C and specified for substantial ripple currents, this part targets power electronics designs where voltage endurance, thermal capability, and reliable ripple handling are required.

Key Features

• Capacitance & Voltage: 100 µF capacitance with a 400 V rated voltage for high‑voltage DC applications.
• Snap‑In Radial Package: Snap‑in terminal, radial can package (25 mm × 25 mm) for robust PCB mounting and ease of assembly in tray packing.
• Operating Temperature Range: −25°C to +105°C rated operating range to support elevated temperature environments.
• Endurance: 2000 hours at 105°C when DC bias plus rated ripple current is applied; capacitance change remains within ±20%, tan δ ≤ 200% of initial spec, and leakage current ≤ initial specified value.
• Ripple Current Capability: 660 mA at 120 Hz (low frequency) and 759 mA at 10 kHz (high frequency), enabling effective smoothing of AC ripple under real operating conditions.
• Leakage and Loss Characteristics: Specified leakage current of 600 µA and a maximum tan δ of 0.20 at 120 Hz and 20°C for predictable dissipation and stability.
• Tolerance: ±20% capacitance tolerance at 120 Hz, 20°C for design margining.
• Safety Feature – Pressure Relief Vent: Built‑in pressure relief vent for safe performance under abnormal conditions, as specified in the series documentation.

Typical Applications

• High‑voltage smoothing: For circuits requiring 400 V DC smoothing where 100 µF bulk capacitance and controlled ripple handling are needed.
• Power electronics modules: Suitable where elevated operating temperatures (up to 105°C) and substantial ripple currents are present.
• Board‑level bulk capacitance: Snap‑in radial mounting provides a durable option for PCB implementations requiring compact high‑voltage capacitors.

Unique Advantages

• High voltage capability: 400 V rating supports higher DC bus voltages, reducing the need for multiple parallel components.
• Compact, manufacturable form factor: 25 × 25 mm radial snap‑in can in tray packing simplifies handling and assembly for volume production.
• Robust thermal endurance: 2000 hours at 105°C endurance rating helps ensure long‑term stability in thermally demanding applications.
• Defined ripple performance: Separate low‑ and high‑frequency ripple specs (660 mA at 120 Hz and 759 mA at 10 kHz) allow designers to size capacitors against real ripple environments.
• Predictable electrical characteristics: Specified tan δ ≤ 0.20 and defined leakage current enable reliable power loss and leakage budgeting in designs.
• Safety focus: Pressure relief vent behavior specified to avoid hazardous conditions in abnormal events.
