LQS2V331MELZ45

The LQS2V331MELZ45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LQS series designed for high‑speed charge/discharge and robust power conditioning. It is a polarized, radial can device specified at 330 µF and 350 V, packaged for snap‑in mounting and tray packing for efficient assembly.

Engineered for power electronics and inverter systems, this capacitor delivers high ripple handling, a wide operating temperature range, and 3,000 hours of endurance at 105°C — offering reliable energy buffering for equipment operating in fluctuating voltage and high‑frequency environments.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 350 V provides energy storage suitable for DC link and charge/discharge applications.
• High‑frequency performance — Specified loss tangent (tan δ) of 0.15 at 20°C and 120 Hz supports stable AC behavior under ripple and switching conditions.
• High ripple current capability — Rated for 1.2 A (120 Hz) and 1.716 A (50 kHz) ripple current to handle both low‑ and high‑frequency ripple in power conversion circuits.
• Robust endurance — 3,000 hours life at 105°C under rated ripple and DC bias, with capacitance and leakage limits defined for reliable long‑term operation.
• Wide operating temperature — Specified for −25°C to +105°C to accommodate a broad range of industrial ambient conditions.
• Snap‑in radial can — 22 mm diameter × 45 mm length, snap‑in terminals for secure PCB mounting and simplified assembly; tray packing for production workflows.
• Leakage current and tolerance — Leakage current listed at 1010 µA and capacitance tolerance of ±20% at 120 Hz, 20°C for predictable sizing in designs.
• RoHS compliant — Meets applicable RoHS requirements for environmental compliance.

Typical Applications

• AC servo and motor drives — Energy buffering and regenerative voltage handling in high‑frequency regenerative circuits for servomotor control.
• Inverters and power converters — DC link smoothing and ripple absorption in general inverter topologies where voltage fluctuations occur.
• Rectifier and voltage doubler circuits — Use in rectifier stages and voltage doubler rectification to stabilize DC output under dynamic loads.

Unique Advantages

• Designed for fast charge/discharge: Series emphasis on high‑speed charge/discharge behavior makes this part suitable for regenerative and switching power applications.
• High ripple tolerance across frequencies: Dual ripple specifications at 120 Hz and 50 kHz provide clear margins for both mains‑frequency and switching‑frequency stress.
• Thermal endurance for demanding environments: 3,000 hours at 105°C ensures sustained performance in high‑temperature installations and continuous operation.
• Compact snap‑in package: 22 × 45 mm radial can with snap‑in terminals streamlines board mounting and mechanical retention in production assemblies.
• Predictable electrical characteristics: Specified tan δ, leakage current, and ±20% tolerance allow engineers to model ESR/impedance and hold‑up time reliably.
• RoHS compliance: Environmentally compliant construction supports regulatory needs for commercial and industrial equipment.
