LAK2D181MELB20

The LAK2D181MELB20 is an aluminum electrolytic capacitor in a snap‑in terminal can, rated 200 V with 180 µF capacitance. It is a general‑purpose, high‑voltage electrolytic designed for applications that require sustained ripple handling and stable performance at elevated temperatures.

Key value comes from its high‑temperature endurance and safety features: rated for operation from −25 °C to +105 °C with a 2000‑hour endurance at 105 °C, defined dissipation factor and controlled leakage current to support reliable operation in equipment exposed to voltage fluctuations.

Key Features

• Electrical core — 180 µF capacitance at 200 V with a tolerance of ±20%, providing predictable bulk capacitance for high‑voltage circuits.
• Dissipation factor (tan δ) — Specified tan δ ≤ 0.20 at 120 Hz and 20 °C to characterize loss behavior under AC excitation.
• Leakage current — Typical leakage current of 0.56 mA, measured after application of rated voltage, supporting stable bias conditions.
• Ripple current capability — Rated for 700 mA at 120 Hz and 840 mA at 10 kHz, enabling effective AC ripple absorption in power applications.
• Thermal and endurance — Operating temperature range −25 °C to +105 °C and endurance of 2000 hours at 105 °C when subjected to rated DC bias plus rated ripple current.
• Safety design — Snap‑in can features improved safety for abnormally excessive voltage and a pressure relief vent designed to operate without producing dangerous conditions.
• Package and mounting — Radial can, snap‑in terminal type with dimensions φ30 × 20 mm (L); supplied in tray packing for production handling.
• Environmental compliance — RoHS compliant.

Typical Applications

• General‑purpose power systems — Suitable for high‑voltage circuits that require bulk capacitance and defined ripple handling at 200 V.
• Equipment in voltage‑fluctuating environments — Designed and specified for applications exposed to fluctuating voltages, with enhanced safety measures for abnormal overvoltage conditions.
• High‑temperature enclosures — Components requiring reliable performance up to 105 °C and long endurance under rated ripple conditions.

Unique Advantages

• 200 V / 180 µF combination: Provides substantial capacitance for high‑voltage designs without increasing system voltage complexity.
