LAK2G181MELA40ZB

The LAK2G181MELA40ZB is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications that require high voltage capability and extended high‑temperature endurance. It combines a 180 µF capacitance at 400 V rating with snap‑in radial can packaging (φ25×40 mm) for secure through‑hole mounting in mass‑production assemblies.

Built for operation from −25 °C to +105 °C and specified for 2000 hours endurance at 105 °C, this part is suitable for equipment exposed to voltage fluctuations and environments that demand predictable long‑term performance and safety features for abnormal overvoltage events.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 400 V rated DC voltage and ±20% tolerance (at 120 Hz, 20 °C).
• High‑temperature Endurance — Rated for operation from −25 °C to +105 °C with 2000 hours endurance at 105 °C when subjected to DC bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 800 mA at 120 Hz and 920 mA at 10 kHz to support power smoothing and ripple handling in AC/DC environments.
• Leakage Current Specified — Leakage current defined by I ≤ 3√(C·V) (µA) after 5 minutes at 20 °C, providing a measurable electrical baseline for design verification.
• Safety Design — Improved safety features for abnormal overvoltage conditions; pressure‑relief vent operation is specified to avoid dangerous outcomes such as flame, ignition, or part dispersion.
• Package & Mounting — Radial, snap‑in can (φ25 × 40 mm) designed for secure snap‑in PCB mounting; supplied in tray packing for mass production.
• RoHS Compliant — Meets applicable RoHS directive requirements.

Typical Applications

• General‑Purpose Power Systems — Bulk capacitance and voltage support in general power electronics where a 400 V rating and 180 µF are required.
• Equipment in Voltage‑Fluctuating Environments — Suited to systems exposed to fluctuating supply voltages thanks to improved safety features and rated endurance at elevated temperature.
• High‑Temperature Applications — Modules that require continuous operation up to 105 °C with a 2000‑hour endurance specification.
• Through‑Hole Power Assemblies — Snap‑in radial can packaging simplifies secure mounting in high‑power PCB designs and supports mass production handling (tray packing).

Unique Advantages

• High‑Voltage Capability: 400 V rating provides margin for high‑voltage power circuits without up‑rating multiple components.
• Long‑Term Reliability at Elevated Temperature: 2000 hours endurance at 105 °C under rated ripple and DC bias supports stable long‑term operation in hot environments.
• Measurable Ripple Performance: Published ripple current values (800 mA @ 120 Hz, 920 mA @ 10 kHz) let designers size thermal and ripple requirements directly from the datasheet values.
• Predictable Electrical Baseline: Leakage current specified as I ≤ 3√(C·V) (µA) after 5 minutes at 20 °C and tan δ ≤ 0.20 at 120 Hz provide verifiable parameters for circuit design and QA.
• Safety‑Focused Construction: Pressure relief vent and improved safety measures reduce the risk of hazardous failure modes during abnormal overvoltage events.
• Production‑Ready Packaging: Tray packing and snap‑in radial can format support high‑volume assembly workflows.
