LAK2G470MELZ25

The LAK2G470MELZ25 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It combines a high rated voltage (400 V) with a compact radial can snap‑in package (φ22 × 25 mm) for board‑level power filtering and energy storage.

Engineered for robust operation in elevated temperatures and fluctuating voltage environments, this part delivers long endurance (2000 hours at 105°C), defined ripple handling, low loss (tan δ ≤ 0.20 at 120 Hz), and RoHS compliance.

Key Features

• Capacitance and Voltage — 47 µF capacitance rated at 400 V DC with ±20% tolerance, suitable for DC power filtering and smoothing.
• High‑temperature Endurance — Rated for 2000 hours at 105°C; endurance verified per datasheet conditions to retain capacitance within specified limits after testing.
• Ripple Current Handling — 350 mA ripple current at 120 Hz and 402.5 mA at high frequency (specification at 10 kHz), enabling effective AC ripple suppression in power stages.
• Low Loss — Tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C for stable performance and reduced heating under AC stress.
• Leakage Current — Low specified leakage current (410 µA) after voltage application, supporting efficient energy retention in DC circuits.
• Robust Safety Design — Snap‑in can with pressure relief vent and improved safety features for abnormal excessive voltage, suitable for equipment operating in fluctuating voltage areas.
• Form Factor & Mounting — Radial can, snap‑in terminal type (tray packing) for secure board mounting and straightforward assembly.
• Operating Range & Compliance — Rated for −25°C to +105°C and compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk and smoothing capacitor for power supplies, providing steady DC filtering at up to 400 V.
• Equipment in fluctuating‑voltage environments — Designed for use in systems subject to voltage fluctuation, leveraging enhanced safety features and abnormal voltage tolerance.
• High‑temperature, long‑life systems — Applicable where sustained operation at elevated temperatures is required, supported by 2000‑hour endurance at 105°C.

Unique Advantages

• Long high‑temperature life: 2000 hours at 105°C provides predictable ageing and extended operational life under thermal stress.
• High voltage capability: 400 V rating supports higher DC bus voltages without additional series components.
• Measured ripple performance: Specified ripple current ratings at both low (120 Hz) and high frequencies (10 kHz) allow designers to size capacitors against real operating conditions.
• Safety‑oriented design: Pressure relief vent and improved abnormal‑voltage protections reduce risk in fluctuating voltage applications.
• Compact snap‑in package: φ22 × 25 mm radial can with snap‑in terminals simplifies board retention and assembly for medium‑power designs.
• Regulatory compliance: RoHS compliant material selection for use in regions requiring restricted substance conformity.
