LAK2G101MELC20

The LAK2G101MELC20 is an aluminum electrolytic capacitor in a snap-in terminal radial can designed for general-purpose power applications. It combines a 400 V rated voltage with a 100 µF capacitance and is specified for operation from −25 °C to +105 °C.

Engineered for environments with supply variation, this part offers extended voltage capability and enhanced safety features to tolerate abnormally excessive voltage conditions while maintaining long-term ripple endurance.

Key Features

• Snap-In Terminal Package Robust radial, can-style snap-in mounting for secure PCB retention and reliable mechanical connection.
• High Voltage Rating Rated voltage: 400 V, suitable for higher-voltage general-purpose power circuits.
• Capacitance and Tolerance 100 µF nominal capacitance with ±20% tolerance (at 120 Hz, 20 °C).
• High Temperature Endurance Specified operating temperature range −25 °C to +105 °C and endurance demonstrated as 2000 hours at 105 °C with rated ripple and DC bias applied.
• Ripple Current Capability Rated ripple current: 550 mA at 120 Hz and 632.5 mA at 10 kHz for the part’s size and rating.
• Leakage and Loss Characteristics Leakage current specification: I ≤ 3√CV (µA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20 °C.
• Safety Features Designed with improved safety performance and a pressure-relief vent to operate without dangerous conditions under abnormal voltage events; for 400 V, the limited DC current rating for 100 µF parts falls into the 4 A category as specified in the series safety table.
• RoHS Compliant Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power circuits — Bulk decoupling and smoothing in higher-voltage general-purpose equipment where robust capacitance and voltage handling are required.
• Equipment subject to voltage fluctuations — Suited for systems operating in environments with variable supply voltages due to its extended voltage range and improved safety features.
• High-temperature installations — Applications that require sustained ripple endurance at elevated temperatures up to 105 °C.

Unique Advantages

• Long ripple endurance: 2000 hours at 105 °C under rated ripple and DC bias ensures durability in demanding thermal and electrical conditions.
• High-voltage capability: 400 V rating provides design headroom for higher-voltage power rails and filtering tasks.
• Safety-oriented design: Pressure-relief vent and series-level protections reduce the risk associated with abnormal over-voltage events.
• Measured ripple performance: Specified ripple currents at both low and high frequencies (550 mA at 120 Hz, 632.5 mA at 10 kHz) let designers align thermal and ripple budgets to real-world operating conditions.
• RoHS compliance: Meets current environmental directive requirements for lead-free applications.
• Snap-in form factor: Provides secure mechanical mounting for robust assembly in power electronics enclosures.
