LQR2V102MSEC

The LQR2V102MSEC is a screw‑terminal aluminum electrolytic capacitor designed for high‑speed charge/discharge and demanding power applications. It delivers 1000 µF capacitance at 350 V with a screw terminal package (φ35×100L) suited for robust industrial assemblies.

Manufactured for applications such as AC servomotor regenerative circuits, general inverters and voltage‑fluctuating equipment, the part offers high ripple handling, extended endurance, and RoHS compliance for reliable system-level performance.

Key Features

• Capacitance & Voltage — 1000 µF rated capacitance at 350 V for bulk energy storage and DC link applications.
• Screw Terminal Package — Radial can with screw terminals for secure, low‑impedance power connections in chassis or bracketed installations (φ35x100L).
• High Ripple Current — 4.3 A at 120 Hz (low frequency) and 6.02 A at 10 kHz (high frequency) to support regenerative and inverter switching loads.
• Loss Tangent (tan δ) — tanδ (DF) of 0.15 at measurement conditions, aiding predictable dissipation characteristics.
• Leakage & Tolerance — 1770 µA specified leakage current and ±20% capacitance tolerance at 20°C, 120 Hz.
• Operating Range & Endurance — Rated for −25°C to +85°C operating temperature and 5000 hours endurance at 85°C under rated conditions.
• Compliance & Production — RoHS‑compliant construction and offered in mass production quantities with cardboard packing.

Typical Applications

• AC Servomotor Regenerative Circuits — Handles high‑frequency regenerative voltage and rapid charge/discharge cycles common in servo drives.
• General Inverters — Used as DC link and smoothing capacitors where high ripple current capability and endurance are required.
• Voltage Doubler / Rectifier Circuits — Suited for rectifier stages including voltage doubler topologies that experience fluctuating voltages.
• Voltage‑Fluctuating Equipment — Intended for systems operating in environments with variable supply conditions, providing energy buffering and stability.

Unique Advantages

• Robust ripple handling: Specified 4.3 A (120 Hz) and 6.02 A (10 kHz) ripple current ratings reduce thermal stress under both low‑ and high‑frequency switching.
• Long endurance at elevated temperature: 5000 hours at 85°C provides predictable lifetime for industrial applications operating near the upper temperature limit.
• Screw terminal convenience: Heavy‑duty screw connections simplify assembly and provide secure electrical and mechanical mounting in power enclosures.
• Clear electrical characteristics: Provided tanδ (0.15) and leakage current (1770 µA) values support thermal and leakage budgeting during system design.
• RoHS compliant and production ready: Environmental compliance and mass production availability streamline procurement and integration.
