LNC2W472MTEH

The LNC2W472MTEH is a screw‑terminal aluminum electrolytic capacitor designed for high‑voltage inverter and industrial power applications. It provides 4.7 mF (4700 µF) capacitance at a 450 V rating in a compact, radial can with screw terminals and stud‑bolt mounting for robust mechanical attachment.

Engineered for high ripple current and high‑frequency charge/discharge duty, this capacitor is suited to industrial power supplies, inverter circuitry and regenerative voltage environments where long life and reliable performance at up to 85°C are required.

Key Features

• Electrical Performance — 4.7 mF (4700 µF) nominal capacitance with ±20% tolerance and a 450 V rated voltage for high‑energy storage and DC bus filtering.
• High Ripple Current — Rated ripple current of 19.2 A at 120 Hz and 26.88 A at 100 kHz to support heavy AC ripple and high‑frequency regenerative loads.
• Thermal and Lifetime — Operating temperature range −40°C to +85°C with a rated load life of 5000 hours at 85°C when exposed to rated ripple current and DC bias.
• Robust Endurance — Designed to withstand charge‑discharge cycling; endurance test includes 50 million cycles (ΔV = rated voltage × 0.3 at 3 Hz) with limits on capacitance change, tan δ, and leakage current.
• Mounting & Package — Radial can with screw terminals and stud bolt mount option for secure mechanical fixation in industrial assemblies.
• Leakage & Safety Characteristics — Leakage current after 5 minutes at rated voltage is specified as not exceeding 3√V (µA) or 5 mA, whichever is smaller (measured at 20°C).
• Compact Size — Smaller package compared with similar series options; dimensional footprint L: 11.5 × D: 7.62 cm (height seated max: 4.528 in) to aid denser power module layouts.
• RoHS Compliant — Conforms to RoHS Directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and DC bus smoothing in high‑voltage power conversion systems.
• Inverter Circuitry — Supports high ripple currents and fast charge/discharge cycles common in motor drive and inverter stages.
• AC Servomotor Regeneration — Handles high‑frequency regenerative voltages in servomotor drives and regenerative braking systems.
• General Inverter Systems — Energy buffering and filtering for general purpose inverters requiring reliable performance at elevated temperatures.

Unique Advantages

• High Ripple Capacity: Ripple current ratings at both 120 Hz and 100 kHz provide design headroom for AC ripple and high‑frequency switching environments.
• Long Operational Life: 5000‑hour load life at 85°C under rated ripple conditions supports sustained operation in industrial applications.
• Compact Screw‑Terminal Package: Radial can with screw terminals and stud mounting delivers secure electrical and mechanical connections while conserving board or chassis space.
• Designed for Charge‑Discharge Duty: Proven endurance for repeated charge/discharge cycles (50 million cycles test) suitable for high‑speed switching applications.
• Predictable Leakage Behavior: Leakage current specification (3√V µA or 5 mA max after 5 minutes at 20°C) enables predictable design margins for power systems.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products requiring restricted substance conformance.
