LAK2D122MELC50

The LAK2D122MELC50 is an aluminum electrolytic, snap-in terminal capacitor specified for 200 V operation with 1200 µF capacitance and ±20% tolerance. It is a radial, can-type snap-in component designed for general-purpose electronic equipment where high voltage endurance and reliable ripple handling are required.

Engineered for elevated operating temperatures, the LAK series offers improved safety features for abnormally excessive voltage and is RoHS compliant. This part is intended for designs that require sustained performance at up to 105°C and endurance under rated ripple current.

Key Features

• Electrical Performance — 200 V, 1200 µF: Rated capacitance of 1.2 mF (1200 µF) at 200 V with ±20% tolerance, suitable where high capacitance and mid‑hundreds volt ratings are required.
• High-temperature Endurance: Specified operating temperature range of −25°C to +105°C and a rated life of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability: Rated ripple current handling of 2.3 A at 120 Hz and 2.76 A at 10 kHz, supporting continuous AC ripple conditions within the specified limits.
• Snap-in, Radial Can Package: Snap-in terminal mounting provides robust mechanical retention for power assemblies and chassis-mounted applications.
• Improved Safety Design: Includes safety measures for abnormal overvoltage conditions; the pressure relief vent is designed to operate without dangerous flame or dispersion of parts.
• Regulatory Compliance: RoHS compliant per the stated directive.

Typical Applications

• General-purpose electronic equipment: Suitable for a wide range of general-purpose circuits requiring bulk capacitance at 200 V.
• Equipment used in voltage-fluctuating areas: Designed with extended voltage range options and safety features that make it well suited for applications exposed to fluctuating supply voltages.
• High-temperature systems: Operates across −25°C to +105°C and maintains specified performance after 2000 hours at 105°C under rated ripple current.
• Systems requiring sustained ripple handling: Capacitor provides continuous ripple current capability (2.3 A @120 Hz, 2.76 A @10 kHz) for designs that must manage steady AC ripple on DC rails.

Unique Advantages

• High-voltage and high-capacitance combination: 200 V rating with 1200 µF capacitance supports energy storage and smoothing needs in mid-voltage designs.
• Long-duration high-temperature reliability: Rated 2000 hours at 105°C under rated ripple current to preserve capacitance, tan δ and leakage current within specified limits after endurance testing.
• Robust snap-in mounting: Snap-in terminals and radial can construction provide secure mechanical retention for chassis and power module assemblies.
• Built-in safety measures: Pressure relief venting and improved abnormal-voltage handling reduce risk of hazardous failure modes under overvoltage conditions.
• Verified ripple performance: Specified ripple current values at both low and high frequencies allow designers to match capacitor selection to expected operating frequencies.
• RoHS compliant: Conforms to the RoHS directive for restricted substances, facilitating regulatory alignment in many markets.
