LGL2W151MELA25

The LGL2W151MELA25 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGL series, engineered for 105°C operation in a compact, ultra-smaller-sized radial can. It provides 150 µF capacitance at a 450 V rating with snap-in mounting and tray packaging for mass production.

Designed for general-purpose applications, this component delivers high-voltage energy storage and ripple handling with defined endurance and temperature characteristics suitable for many power-electronics designs.

Key Features

• Capacitance & Voltage: 150 µF nominal capacitance with a 450 V rated voltage for high-voltage DC bus and energy-storage requirements.
• Snap-in Radial Can Package: Snap-in terminal type in a 25 × 25 mm (Ø × L) radial can for secure mechanical retention and straightforward PCB assembly in through-hole layouts.
• High Temperature Endurance: Rated for operation from −25°C to +105°C with an endurance of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability: Specified ripple current of 740 mA at 120 Hz (low frequency) and 1.058 A at 50 kHz (high frequency), supporting both mains-frequency and higher-frequency applications.
• Leakage and Loss Characteristics: Typical leakage current listed as 770 µA; tangent of loss angle (tan δ) ≤ 0.20 at 20°C and 120 Hz for the 450 V rating.
• Capacitance Tolerance & Polarization: ±20% capacitance tolerance at 120 Hz, 20°C; polarized device for DC applications.
• Packaging & Production: Tray packing prepared for mass production volumes.

Typical Applications

• General-Purpose Power Electronics: Suitable for circuits requiring 150 µF at high DC voltages with snap-in mounting for robust assembly.
• High-Voltage Energy Storage: Used where compact, 450 V-rated electrolytic capacitance is required in a radial can form factor.
• Industrial and Commercial Equipment: Applicable to general-purpose designs that demand 105°C-rated operation and defined endurance (2000 h at 105°C).

Unique Advantages

• High Voltage Rating: 450 V rating enables use on higher-voltage DC buses without series stacking.
• Compact, Ultra-Smaller Size: 25 × 25 mm (Ø × L) dimensions deliver 150 µF capacitance in a small radial can footprint for space-constrained designs.
• Defined High-Temperature Endurance: 2000 hours at 105°C provides predictable aging and performance retention under elevated temperatures.
• Dual-Frequency Ripple Performance: Specified ripple currents at both 120 Hz and 50 kHz support designs that operate across a range of switching frequencies.
• Manufacturing-Ready Packaging: Tray packing and snap-in termination simplify handling and installation in mass-production assembly flows.
