LQS2V471MELA50

The LQS2V471MELA50 is a Nichicon LQS series aluminum electrolytic capacitor in a snap‑in terminal radial can designed for high‑speed charge–discharge applications. It is a polarized 470 µF, 350 V device specified for operation from –25 °C to 105 °C and built for demanding power‑conversion environments.

Engineered for high‑frequency regenerative voltage and fluctuating voltage conditions, this part targets industrial power electronics such as AC servomotor drives, general inverters and rectifier circuits (including voltage doubler configurations). It is RoHS‑compliant and optimized for reliability under heavy ripple and cycling loads.

Key Features

• Capacitance & Rated Voltage: 470 µF nominal capacitance at a rated voltage of 350 V, with a tolerance of ±20% (120 Hz, 20 °C).
• High‑temperature operation: Rated for –25 °C to +105 °C operating temperature, with an endurance rating of 3000 hours at 105 °C under rated DC bias plus rated ripple current.
• Snap‑in radial can package: Snap‑in terminal mounting for secure PCB installation in compact radial can form factor (size L: 5 × D: 2.5 cm).
• High‑speed charge–discharge endurance: Designed for high frequency charge–discharge duty—endurance validated for 50 million charge‑discharge cycles at room temperature with capacitance, dissipation factor and leakage current remaining within specified limits.
• Ripple current capability: Specified ripple performance of 1.4 A at 120 Hz and 2.002 A at 50 kHz, supporting both line‑frequency and high‑frequency applications.
• Leakage current specification: Leakage current after 5 minutes at 20 °C is limited by I ≤ 3√(C·V) µA (C in µF, V in V), providing predictable self‑discharge behavior for power designs.
• Durability and shelf life: Shelf life and endurance are defined in the datasheet (including a 1000‑hour shelf test at 105 °C followed by voltage treatment), supporting predictable lifecycle planning.

Typical Applications

• AC servomotor drives: Handles high‑frequency regenerative voltage and fast charge–discharge cycles encountered in motor control systems.
• General inverters and power converters: Provides bulk energy storage and smoothing for inverter DC links and intermediate circuits subject to fluctuating voltages.
• Voltage doubler rectifier circuits: Suited for rectifier stages in voltage doubler topologies where robust DC blocking and ripple handling are required.
• Industrial equipment in unstable grids: Reliable performance for equipment operating in voltage‑fluctuating environments due to high‑temperature rating and rated endurance.

Unique Advantages

• Engineered for high‑temperature duty: 105 °C continuous rating and 3000‑hour endurance at that temperature reduce risk of premature aging in hot enclosures.
• Proven charge–discharge robustness: Specified endurance for 50 million charge–discharge cycles ensures stable capacitance, dissipation factor and leakage after extensive cycling.
• High‑frequency ripple support: Explicit ripple current ratings at both 120 Hz and 50 kHz make the part suitable across a wide range of converter and regenerative scenarios.
• Predictable leakage behavior: Leakage current limit defined by I ≤ 3√CV (µA) after voltage application enables accurate power‑loss and hold‑up calculations.
• Snap‑in mounting for secure assembly: Radial, snap‑in can simplifies board retention and mechanical stability in industrial assemblies.
• RoHS compliant: Conforms to RoHS directives (2011/65/EU, (EU)2015/863) for restrictions on hazardous substances.
