• Thermal and Endurance — Rated for operation from −25°C to +105°C (category range for 315 V class) and specified to withstand 3000 hours of rated ripple current at 105°C.
• Ripple Current Capability — Rated ripple currents include 750 mA at 120 Hz and 1.073 A at 50 kHz, supporting AC ripple filtering and smoothing duties at multiple frequencies.
• Package and Mounting — Radial can snap-in package with snap-in terminals for secure board retention; nominal dimensions L: 2.5 × D: 2.2 cm and maximum seated height 2.5 cm.
• Reliability Characteristics — Endurance and shelf-life specifications: capacitance change within ±20% after endurance testing and defined leakage current and tan δ limits per the LGU series datasheet.
• Regulatory — RoHS compliant.
• Identification — Marked with white lettering on a black sleeve for clear part identification.

Typical Applications

• High-Voltage Power Supplies — 315 V rating and 120 µF capacitance make the LGU2F121MELZ suitable for bulk filtering and smoothing in high-voltage DC rails.
• Industrial Power Conversion — Designed to tolerate elevated temperatures (up to 105°C) and continuous ripple, helping stabilize DC bus voltages in industrial converters and inverters.
• DC Link and Energy Storage — Bulk capacitance and specified ripple current support energy storage and transient buffering on DC link applications.
• General-Purpose Electronic Equipment — A robust, RoHS-compliant snap-in capacitor choice for a wide range of commercial and industrial electronics requiring polarized, high-voltage capacitance.
