LQS2W151MELA30

The LQS2W151MELA30 is an aluminum electrolytic snap‑in capacitor designed for high-voltage power applications. It provides 150 µF capacitance at a 450 V rating with a ±20% tolerance and a polarized, radial can snap‑in package.

Engineered for systems subject to fluctuating voltages and high-frequency charge‑discharge cycles, this capacitor is suited for regenerative circuits in AC servomotors, general inverters, and rectifier circuits such as voltage doublers. It is RoHS compliant and rated for operation from −25°C to +105°C.

Key Features

• Rated Voltage & Capacitance — 450 V rated voltage with 150 µF nominal capacitance and ±20% tolerance for high-voltage energy storage and smoothing.
• High Temperature Operation — Specified operating range from −25°C to +105°C with an endurance specification of 3000 hours at 105°C, supporting sustained elevated-temperature use.
• Snap‑In Radial Can Package — Snap‑in terminal mounting designed for secure chassis or PCB installation in power assemblies.
• High-Frequency Performance — Rated ripple current of 790 mA at 120 Hz and 1.13 A at 50 kHz, supporting both low- and high-frequency ripple handling in power conversion circuits.
• Charge‑Discharge Durability — Series-level charge‑discharge endurance testing (50 million cycles, 6 Hz, room temperature) verifies stability of capacitance, tan δ, and leakage after repetitive cycling.
• Polarized Design — Polar capacitor construction suitable for DC and rectified applications where polarity is maintained.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servomotor Regeneration — Absorbs and smooths high-frequency regenerative voltages in servo drive regenerative circuits.
• General Inverters — Provides DC link energy storage and ripple suppression in inverter front ends and power conversion stages.
• Voltage Doubler Rectifiers — Suited for rectifier circuits that use voltage doubler topologies where high DC voltage capability is required.
• Equipment in Fluctuating Voltage Environments — Designed for systems exposed to varying supply conditions, providing stable capacitance and leakage performance under stress.

Unique Advantages

• High DC Voltage Handling — 450 V rating enables use in high-voltage power rails and rectifier outputs without additional series stacking.
• Designed for Repetitive Cycling — Endurance to extensive charge‑discharge cycles helps maintain performance in regenerative and pulsed-power applications.
• Robust Thermal Endurance — 3000‑hour rating at 105°C provides predictable lifetime for elevated-temperature installations.
• Broad Frequency Ripple Capability — Specified ripple current at both 120 Hz and 50 kHz supports mixed-frequency power systems and reduces thermal stress from ripple.
• Secure Snap‑In Mounting — Snap‑in terminal format simplifies mechanical retention in power assemblies and chassis-mounted configurations.
• Regulatory Compliance — RoHS conformity supports use in products requiring lead‑restricted component selection.
