LAK2D391MELA30

The LAK2D391MELA30 is a Nichicon LAK series aluminum electrolytic capacitor in a snap‑in terminal, radial can package. It delivers 390 µF at a 200 V rating with a compact 25 mm diameter by 30 mm length footprint and is intended for general‑purpose electronic and electrical equipment.

Designed for applications exposed to fluctuating voltages, this snap‑in capacitor combines high ripple handling and a 105 °C permissible operating temperature to provide dependable decoupling and energy storage where robust performance and long endurance are required.

Key Features

• Capacitance & Voltage: 390 µF nominal capacitance at a 200 V rated voltage, with ±20% tolerance for predictable charge storage and sizing.
• Package & Mounting: Snap‑in terminal, radial can design (φ25 × 30 mm) for secure board retention and ease of installation in power assemblies.
• 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 conditions.
• Ripple Current Capability: 1.2 A at 120 Hz (low frequency) and 1.44 A at 10 kHz (high frequency), supporting substantial AC ripple handling in power circuits.
• Leakage & Loss Characteristics: Specified leakage current of 830 µA and tan δ (dissipation factor) ≤ 0.20 at 20 °C, 120 Hz for predictable electrical behavior.
• Safety Feature: Pressure relief vent incorporated to mitigate abnormal overvoltage conditions and enhance operational safety.
• Compliance: RoHS‑compliant construction for adherence to lead‑restriction environmental requirements.

Typical Applications

• General‑purpose power equipment: Suitable for electronic and electrical systems requiring a 200 V electrolytic capacitor with robust ripple handling and extended operating temperature.
• Industrial equipment exposed to voltage fluctuation: Engineered for environments where supply voltage can vary, leveraging its safety venting and endurance rating.
• Power supply modules and converters: Provides bulk energy storage and ripple smoothing at 200 V system levels while supporting continuous ripple current at both low and high frequencies.

Unique Advantages

• Long high‑temperature life: 2000 hours endurance at 105 °C ensures stable capacitance and leakage over extended high‑temperature operation.
• Wide operating temperature range: −25 °C to +105 °C supports deployments across varied ambient conditions without derating beyond specified limits.
• High ripple tolerance: 1.2 A (120 Hz) and 1.44 A (10 kHz) ratings enable effective handling of AC ripple in demanding power circuits.
• Predictable electrical performance: Specified tan δ ≤ 0.20 and defined leakage current deliver consistent dissipation and self‑discharge behavior for design certainty.
• Snap‑in mounting convenience: Radial, snap‑in can simplifies mechanical retention for assemblies requiring secure board mounting.
• Safety‑oriented design: Pressure relief vent operation reduces risk under abnormal voltage conditions, aligning with safe system design practices.
