LNT2A472MSE

The LNT2A472MSE is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications. It is a polarized radial can with screw terminals, rated 4.7 mF at 100 V and specified for operation from –40 °C to +105 °C.

Engineered for high ripple current and robust thermal endurance, this RoHS-compliant capacitor suits designs that require secure terminal connections, elevated operating temperature, and predictable life performance at rated conditions.

Key Features

• Capacitance & Voltage — 4.7 mF capacitance at a rated voltage of 100 V with ±20% tolerance, providing defined bulk energy storage for power filtering and decoupling.
• Screw Terminal Mounting — Radial can package with screw terminals for secure, low-resistance connections in chassis- or bus-mounted power systems.
• High Ripple Current — Rated ripple current of 3.8 A at 120 Hz and 4.37 A at 100 kHz, enabling effective smoothing under high AC ripple conditions.
• Temperature & Endurance — Operating range –40 °C to +105 °C and specified load life of 2,000 hours at 105 °C for the 100 V class, offering predictable performance in elevated-temperature environments.
• Package Dimensions — Compact radial can size with body dimensions L: 10 × D: 3.5 cm, supporting installation where a screw-terminal footprint is required.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction in DC power supplies where high ripple current handling is required.
• Industrial Power Modules — Chassis- or bracket-mounted energy storage and decoupling for motor drives and control power buses using secure screw-terminal connections.
• Backup & Hold-up Circuits — Energy reservoir for short-term hold-up and ride-through functions at elevated ambient temperatures.

Unique Advantages

• Secure Mechanical Connection: Screw terminals provide reliable, low-impedance attachment ideal for high-current bus or field-serviceable assemblies.
• High Ripple Capability: Defined ripple current ratings at both 120 Hz and 100 kHz allow designers to match capacitor performance to real-world power waveforms.
• High-Temperature Endurance: Rated for operation to +105 °C with an established load life (2,000 hours at 105 °C for 10–250 V range), supporting designs exposed to sustained heat.
• Compact Radial Can: The L: 10 × D: 3.5 cm package balances capacitance with a moderate chassis footprint for space-conscious power assemblies.
• Regulatory Compliance: RoHS compliance helps meet environmental and supply-chain requirements.

Why Choose LNT2A472MSE?

The LNT2A472MSE positions itself as a practical, specification-driven choice for engineers needing a screw-terminal aluminum electrolytic capacitor that combines substantial capacitance (4.7 mF) with a 100 V rating, high ripple current capability, and operation to +105 °C. Its construction and mounting style simplify integration into power systems that demand robust electrical and mechanical connections.

This part is well suited to procurement for industrial and power electronics designs where clear, verifiable performance (ripple current, temperature range, and load life) and RoHS conformance are required. The documented endurance at 105 °C and the screw-terminal form factor support reliable long-term operation in high-demand environments.
