LGL2W121MELZ25

The LGL2W121MELZ25 is an aluminum electrolytic capacitor in a snap-in terminal can designed for general-purpose electronic applications. It delivers 120 µF capacitance at a 450 V rated voltage in an ultra-smaller-sized package (φ22 × 25 mm) with tray packing for mass production.

Engineered for elevated operating temperatures, the capacitor is specified for –25°C to +105°C and an endurance of 2000 hours at 105°C, offering reliable performance where high voltage, compact size, and through-hole snap-in mounting are required.

Key Features

• Capacitance & Voltage: 120 µF rated capacitance at 450 V, suitable for high-voltage energy storage and smoothing within the device’s rated limits.
• High Temperature Endurance: Specified operating range of –25°C to +105°C with an endurance rating of 2000 hours at 105°C when tested under DC bias plus rated ripple current.
• Compact Snap‑in Package: φ22 × 25 mm aluminum can with snap-in terminals for secure board mounting and tray packing for production handling.
• Ripple Current Performance: Rated ripple current specified as 690 mA at 120 Hz and 986.7 mA at 50 kHz; frequency coefficients provided in the series datasheet allow ripple scaling across frequencies.
• Electrical Stability: Capacitance tolerance ±20% at 120 Hz, 20°C; tan δ for 450 V grades specified up to 0.20 (max) at 120 Hz, 20°C.
• Leakage & Reliability: Leakage current specified by series formula I ≤ 3√(C) µA after 5 minutes at rated voltage and 20°C; shelf-life and endurance limits are defined with post-test recovery criteria.
• Polarized Electrolytic: Polarized construction for standard DC applications where polarity is maintained.

Typical Applications

• General-purpose high-voltage circuits: Provides 120 µF at 450 V for energy storage and smoothing in circuits that require a compact, high-voltage electrolytic capacitor.
• Board-mounted power components: Snap-in terminal design enables secure through-hole mounting for assemblies produced in tray-packed volumes.
• High-temperature environments: Rated for continuous operation up to 105°C with defined endurance performance (2000 hours at 105°C) for designs that demand elevated temperature reliability.

Unique Advantages

• High Voltage in a Small Footprint: 450 V rating combined with a φ22 × 25 mm can delivers substantial capacitance where PCB space is limited.
• Robust Thermal Endurance: Endurance specifications (2000 hours at 105°C) provide predictable aging and performance under elevated-temperature stress.
• Production-Friendly Packaging: Tray packing tailored for mass production reduces handling complexity during assembly.
• Snap‑in Mounting Security: Snap-in terminal package gives a reliable mechanical and electrical board connection for through-hole assemblies.
• Frequency-aware Ripple Handling: Published ripple current values and frequency coefficients allow designers to size capacitors for expected ripple profiles across frequencies.
