LGA2W471MELB45

The LGA2W471MELB45 is a Nichicon snap-in aluminum electrolytic capacitor offering 470 µF capacitance at a 450 V rated voltage in a radial, snap-in can package. It is designed for general-purpose applications that require high capacitance, substantial ripple handling and extended operational life.

Key electrical and mechanical attributes include snap-in mounting, a wide operating temperature range of -40 °C to 105 °C, rated ripple current capability, RoHS compliance, and a rated lifetime of 5000 hours at 105 °C. The part is supplied in tray packing and is released for mass production.

Key Features

• Capacitance & Voltage — 470 µF capacitance with a 450 V rated voltage for bulk energy storage and decoupling where high voltage and capacitance are required.
• Long Life — Endurance rating of 5000 hours at 105 °C when subjected to DC bias plus rated ripple current, with specified limits for capacitance change, tan δ and leakage current.
• Wide Temperature Range — Rated for operation from -40 °C to +105 °C, supporting applications across elevated and sub-zero ambient conditions.
• High Ripple Current Capability — Rated ripple current of 2.85 A at 120 Hz (105 °C) and 4.075 A at 100 kHz, supporting circuits with significant AC ripple stress.
• Snap-In Radial Can Package — Snap-in terminal type and radial can construction for secure PCB mounting and mechanical stability.
• Tight Manufacturing Controls — Supplied in tray packing and released for mass production to support volume assembly processes.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• General-purpose power circuits — Used where a 470 µF, 450 V electrolytic capacitor with high ripple capability and 5000-hour life at 105 °C is required for bulk filtering or energy buffering.
• High-ripple environments — Suitable for circuits that impose sustained AC ripple stresses, leveraging the specified 2.85 A (120 Hz) and 4.075 A (100 kHz) ripple ratings.
• Heat-exposed systems — Applicable in assemblies operating up to 105 °C thanks to the capacitor's rated temperature range and endurance at elevated temperature.

Unique Advantages

• Proven longevity: 5000-hour endurance at 105 °C with defined recovery criteria ensures stable capacitance, tan δ and leakage performance over long-duration operation.
• Robust ripple handling: Explicit ripple current ratings for both low and high frequencies allow designers to size capacitors confidently for thermal and ripple stress.
• Wide thermal tolerance: -40 °C to +105 °C operating range supports deployment across diverse ambient conditions without derating the specified lifetime.
• Production-ready packaging: Tray packing and release for mass production simplify procurement and high-volume assembly integration.
• Secure PCB attachment: Snap-in radial can package delivers mechanical stability on the board and familiar assembly workflow for power components.
• Regulatory compliance: RoHS compliance supports use in regions and products requiring restricted-substance adherence.
