LNT1E473MSEN

The LNT1E473MSEN is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNT series. It delivers high bulk capacitance in a radial can with screw terminals, optimized for general‑purpose power electronics requiring robust electrical and mechanical connections.

Key attributes include 47,000 µF capacitance at 25 V, high ripple current capability, low leakage, and a wide operating temperature range, making this part suitable for power‑smoothing, energy buffering, and DC bus support in industrial and commercial systems.

Key Features

• Capacitance & Voltage — 47 mF (47,000 µF) rated at 25 V with ±20% tolerance (measured at 120 Hz, 20°C), providing substantial bulk energy storage for DC systems.
• High Ripple Current — 8.3 A at 120 Hz (low frequency) and 9.545 A at 100 kHz (high frequency), supporting continuous ripple handling in power supply and inverter applications.
• Dielectric Loss (tan δ) — 0.5 (DF) specified at 20°C and 120 Hz, enabling designers to assess dissipation and heating under AC ripple conditions.
• Low Leakage Current — Specified leakage current of 3,250 µA, suitable for power systems where controlled leakage is required.
• Thermal Endurance & Operating Range — Rated for operation from −40°C to +105°C with a 2,000‑hour endurance at 105°C, supporting sustained elevated‑temperature service.
• Robust Mechanical Package — Radial can with screw terminals (φ51 × 80L); the φ51 size in the LNT series uses an M5 nominal terminal bolt for secure electrical connections.
• Compliance & Production — RoHS‑compliant and in mass production; supplied with cardboard packing.

Typical Applications

• Power‑supply bulk smoothing — High capacitance and rated ripple current make this capacitor well suited for DC link and bulk energy storage in power supplies.
• Industrial power electronics — Screw‑terminal mounting and high ripple capability provide reliable connections for inverters, motor drives, and industrial converters.
• Backup and energy buffering — Large stored charge supports short‑term energy buffering and hold‑up in UPS, standby power, and energy‑harvesting subsystems.
• High‑power filtering — Suitable for filtering and decoupling in systems where significant AC ripple is present at both low and high frequencies.

Unique Advantages

• Substantial bulk capacitance in a compact can: 47,000 µF in a φ51 × 80L package reduces the need for multiple smaller capacitors and saves PCB/assembly space.
• High ripple tolerance across frequencies: Specified ripple current at 120 Hz and 100 kHz enables designers to address both line‑frequency and switching‑frequency stresses with a single part.
• Screw‑terminal reliability: M5 screw terminals provide secure, low‑impedance connections for high‑current applications and simplify field wiring and assembly.
• Thermal durability: Rated for −40°C to +105°C with a 2,000‑hour life at 105°C, offering predictable end‑of‑life behavior in elevated‑temperature environments.
• Production readiness and compliance: RoHS‑compliant and currently in mass production, with standard cardboard packing for shipment and storage.
