LQS2V221MELZ35

The LQS2V221MELZ35 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor rated at 220 µF and 350 V. Built for general‑purpose power applications, it combines high ripple handling and a 105°C endurance rating for use in equipment with fluctuating voltages and high‑frequency charge/discharge demands.

As part of the LQS series, this radial can (snap‑in) capacitor is optimized for high ripple and long life: rated ripple current, controlled dissipation factor, and a 3000‑hour endurance at 105°C support robust performance in power electronics designs.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 350 V DC rating and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Handling — Rated ripple current of 1.0 A at 120 Hz and 1.43 A at 50 kHz provides effective smoothing and energy buffering in rectifier, inverter, and regenerative circuits.
• Temperature & Lifetime — Operational range from −25°C to +105°C with an endurance specification of 3000 hours at 105°C under rated bias plus ripple current.
• Charge/Discharge Endurance — Series‑level charge/discharge endurance: specified behavior after 50 million cycles (6 Hz) at room temperature with applied charge/discharge voltage equal to rated voltage + 0.35 V.
• Electrical Loss & Leakage — Dissipation factor (tan δ) up to 0.15 at 20°C and 120 Hz; measured leakage current listed as 830 µA for this part.
• Package & Mounting — Snap‑in, radial can package (φ22 × 35 mm) for secure PCB mounting and tray packing suitable for production assembly.
• RoHS Compliant — Conforms to RoHS requirements as indicated in the LQS series documentation.

Typical Applications

• Power Inverters and Drives — Energy buffering and smoothing in inverter DC link circuits and AC servomotor systems where high ripple current and voltage fluctuations occur.
• Regenerative Systems — Support for high‑frequency regenerative voltage applications and charge/discharge cycles in equipment with bidirectional energy flow.
• Rectifier Circuits — Use in rectifier and voltage‑doubler circuits requiring high voltage rating and stable capacitance under ripple load.

Unique Advantages

• High Voltage Capability: 350 V rating enables use in medium‑voltage DC link and rectifier applications without series stacking.
• Robust Ripple Performance: Dual ripple current specs (1.0 A at 120 Hz; 1.43 A at 50 kHz) provide design flexibility across low and higher frequency power stages.
• Extended High‑Temperature Endurance: 3000 hours at 105°C under rated conditions ensures predictable lifetime in thermally demanding environments.
• Proven Charge/Discharge Durability: Series endurance data for 50 million cycles at defined test conditions supports applications with frequent energy cycling.
• Serviceable Form Factor: Snap‑in radial can (φ22 × 35 mm) offers a compact, mechanically stable solution for PCB installation in production systems.
