LAK2D470MELZ20ZB

The LAK2D470MELZ20ZB is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose electronic applications requiring a 47 µF capacitance at 200 V. Its compact 22 × 20 mm can, polarized construction and snap-in mounting simplify installation in assemblies that demand reliable bulk capacitance.

This part is engineered for robust thermal and ripple performance with rated operation from -25°C to +105°C, endurance of 2000 hours at 105°C under rated ripple current, and RoHS compliance for environmental compatibility.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance at 200 V, specified with ±20% tolerance for predictable DC energy storage.
• Mounting & Package — Snap-in terminal type in a radial can package (22 mm diameter × 20 mm length) for secure board anchoring and straightforward assembly.
• Thermal Endurance — Rated for operation from -25°C to +105°C with a 2000-hour endurance rating at 105°C when subjected to DC bias plus rated ripple current.
• Ripple Current Performance — 350 mA ripple current at 120 Hz and 420 mA at 10 kHz, supporting applications with continuous AC ripple on DC rails.
• Low Leakage & Loss — Low leakage current of 0.29 mA (typical for this size and rating) and a maximum tanδ of 0.20 at 120 Hz, 20°C for controlled dissipation.
• Safety & Abnormal Voltage Handling — Designed with improved safety features for abnormally excessive voltage and a pressure relief vent to mitigate unsafe conditions.
• Compliance — RoHS compliant for restricted substances standards.

Typical Applications

• General Purpose Electronics — For circuits requiring a 47 µF, 200 V polarized capacitor with snap-in mounting in general-purpose assemblies.
• High-Temperature Systems — Suitable for equipment operating up to +105°C, backed by a 2000-hour endurance specification at 105°C.
• High Ripple Environments — Appropriate where rated ripple currents (350 mA at 120 Hz, 420 mA at 10 kHz) are present on DC rails.

Unique Advantages

• Long-Term High-Temperature Reliability: 2000 hours endurance at 105°C under rated ripple current provides extended service life in elevated-temperature applications.
• Robust Ripple Handling: Specified ripple currents at both low and high frequencies (350 mA at 120 Hz, 420 mA at 10 kHz) reduce the risk of premature heating under AC stress.
• Compact Snap-In Form Factor: 22 × 20 mm can with snap-in terminals simplifies mechanical retention and board assembly compared to other large electrolytic formats.
• Controlled Leakage and Loss: Low leakage current (0.29 mA) and tanδ ≤ 0.20 help maintain efficiency and predictable behavior in DC circuits.
• Enhanced Safety Design: Pressure relief venting and improved tolerance to abnormal voltage conditions reduce risk in overvoltage events.
• Regulatory Compatibility: RoHS compliance supports environmental requirements in modern electronics manufacturing.
