LGL2G471MELA45

The LGL2G471MELA45 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It provides 470 µF capacitance at a 400 V rating in a compact snap-in can package engineered for operation from –25°C to +105°C.

Designed for engineers who need high-voltage bulk capacitance with elevated-temperature endurance and reliable PCB retention, this part combines high ripple handling and long-term stability for demanding industrial and power-supply environments.

Key Features

• Electrical Rating — 470 µF capacitance at a 400 V rated voltage, ±20% tolerance (120 Hz, 20°C).
• High Temperature Operation — Rated for continuous use from –25°C to +105°C, with endurance specified for 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Snap-In Mounting — Radial, can-type snap-in termination for secure PCB retention and straightforward assembly in power assemblies.
• Ripple Current Capability — Rated ripple 1500 mArms; measured ripple current examples include 1.5 A at 120 Hz and 2.145 A at 50 kHz (frequency coefficient applied).
• Leakage Current — Part-specific leakage current listed as 1.30 mA for the 470 µF, 400 V size.
• Low-Temperature Stability — Impedance ratio Z(–25°C)/Z(+20°C) up to 8 (120 Hz measurement), supporting use across the specified temperature range.
• Dissipation Factor — tan δ max. 0.15 at 400 V (measured at 120 Hz, 20°C) for predictable AC behavior.
• Endurance and Shelf Life — After 2000 hours at 105°C under rated conditions, capacitance change remains within ±20%, with tan δ and leakage current meeting specified limits; shelf life conditions also specified (1000 hours at 105°C plus voltage treatment).
• Compact Footprint — Physical size 25 × 45 mm (diameter × length) providing high capacitance in a smaller snap-in form factor.

Typical Applications

• General-purpose power supplies — Bulk filtering and energy storage where 400 V, 470 µF capacitance and elevated-temperature endurance are required.
• Industrial power electronics — DC link and smoothing applications that benefit from snap-in mounting and specified ripple current handling at both low and high frequencies.
• High-voltage assemblies — Systems needing compact high-voltage capacitors with defined leakage, dissipation, and low-temperature impedance characteristics.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage DC circuits without series stacking.
• Elevated-temperature endurance: 2000 hours at 105°C specification provides a clear, verifiable endurance metric for thermal reliability planning.
• Robust ripple performance: 1500 mArms rated ripple and documented frequency coefficients support predictable behavior across frequencies up to 50 kHz and beyond.
• Secure snap-in mounting: Radial snap-in terminals simplify board assembly while providing mechanical stability in power modules and large PCBs.
• Compact form factor: 25 × 45 mm size delivers substantial capacitance in a smaller envelope for space-constrained designs.
• Measured electrical characteristics: Specified leakage current and tan δ values permit accurate loss and thermal budgeting during design.
