LNT1A473MSEN

The LNT1A473MSEN is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNT series, offering 47,000 µF capacitance at 10 V in a radial can with screw terminals. It is designed for general‑purpose power applications that require large bulk capacitance, reliable ripple handling, and extended operation up to 105°C.

With high ripple current capability, a wide operating temperature range (−40°C to +105°C) and a rated endurance of 2,000 hours at 105°C, this component suits designs where robust energy storage and sustained performance under thermal stress are required.

Key Features

• High Capacitance — 47,000 µF (47 mF) nominal capacitance for bulk energy storage and smoothing in low‑voltage power stages.
• Rated Voltage — 10 V working voltage suitable for low‑voltage power rails and storage applications.
• Screw‑Terminal, Radial Can Package — φ35 × 100 mm can with screw terminals for secure wiring and high‑current connections.
• Wide Temperature Range — Operates from −40°C to +105°C, supporting demanding ambient conditions.
• Endurance — Rated life of 2,000 hours at 105°C under rated ripple current and DC bias.
• High Ripple Current Capability — 6.2 A at 120 Hz (low frequency) and 7.13 A at 100 kHz (high frequency), enabling effective ripple absorption across frequencies.
• Leakage Current — Specified leakage current of 2,050 µA.
• Loss Tangent (tan δ) — tan δ = 0.65 (measured at 20°C, 120 Hz), providing a defined dissipation characteristic for design calculations.
• Capacitance Tolerance & Polarization — ±20% tolerance at 120 Hz, 20°C; polarized device.
• RoHS Compliant & Production Status — RoHS compliant and available in mass production with cardboard packing.

Typical Applications

• General‑Purpose Power Supplies — Bulk smoothing and energy buffering on low‑voltage rails where large capacitance and robust ripple handling are required.
• Industrial Power Electronics — Energy storage and decoupling in control power systems operating across wide ambient temperatures.
• Backup and Hold‑up Circuits — Providing stored charge for short‑duration hold‑up where high capacitance at low voltage is necessary.

Unique Advantages

• Substantial Energy Storage: 47,000 µF provides significant bulk capacitance for smoothing and transient support, reducing the need for large arrays of smaller capacitors.
• Robust Ripple Handling: Specified ripple currents at both 120 Hz and 100 kHz allow designers to quantify thermal stress and ESR heating across low and high frequency components of ripple.
• Thermal Endurance: Rated 2,000 hours at 105°C under rated conditions, enabling deployment in thermally demanding environments with predictable aging behavior.
• Secure Connections: Screw‑terminal mounting provides reliable mechanical and electrical contact for high‑current wiring and easier serviceability.
• Clear Electrical Parameters: Defined leakage current and tan δ (0.65 at 20°C, 120 Hz) simplify thermal and loss budgeting during design verification.
• Regulatory Compliance & Availability: RoHS compliant and in mass production with cardboard packing for standard procurement and assembly handling.
