LGL2G681MELC35

The LGL2G681MELC35 is an aluminum electrolytic, snap-in terminal capacitor rated at 680 µF and 400 V, designed for general-purpose applications. It features an ultra-smaller-sized φ35 × 35 mm can and is specified for operation up to 105°C.

Key value propositions include high-temperature endurance, defined ripple-current performance across frequencies, and a compact snap-in package for efficient board or chassis mounting.

Key Features

• Capacitance & Voltage  680 µF nominal capacitance with a 400 V rated voltage and ±20% capacitance tolerance at 120 Hz, 20°C.
• High-temperature Endurance  Rated for operation from –25°C to +105°C with an endurance specification of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Snap-in Mounting  Radial, can-type snap-in terminals for secure, repeatable chassis/PCB mounting.
• Compact Package  Ultra-smaller-sized can: φ35 × 35 mm (L: 3.5 × D: 3.5 cm), suitable where high-voltage bulk capacitance must fit a constrained footprint.
• Ripple Current Performance  Rated ripple current of 1.74 A at 120 Hz (low frequency) and 2.488 A at 50 kHz (high frequency), with frequency coefficients provided for scaling across operating frequencies.
• Electrical Stability  Leakage current specified by I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ max 0.15 at 400 V (measured at 120 Hz, 20°C).
• Low-temperature Behavior  Impedance stability characterized with Z(–25°C)/Z(+20°C) ≤ 8, for defined low-temperature performance.

Typical Applications

• General-purpose systems  Suited for designs requiring a 400 V, 680 µF snap-in capacitor for general-purpose smoothing and bulk energy storage.
• High-temperature operating environments  Appropriate where sustained operation up to 105°C and 2000-hour endurance at that temperature are required.
• Compact high-voltage assemblies  Used where a smaller φ35 × 35 mm snap-in can is needed to deliver high-voltage bulk capacitance in constrained spaces.

Unique Advantages

• High-voltage bulk capacitance: Provides 680 µF at 400 V for designs that require substantial stored charge in a single component.
• Defined high-temperature lifetime: 2000 hours at 105°C under rated conditions delivers a clear, verifiable endurance characteristic for thermal-stressed designs.
• Frequency-aware ripple handling: Published ripple-current values at 120 Hz and 50 kHz plus frequency coefficients allow designers to size capacitors against actual operating spectra.
• Compact, snap-in form factor: φ35 × 35 mm radial can with snap-in terminals simplifies mounting and integration in space-constrained power or control assemblies.
• Measured electrical characteristics: Specified limits for leakage current and tan δ enable predictable electrical behavior and easier qualification in designs.
