LNR1E473MSEN

The LNR1E473MSEN from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNR series, delivering 47,000 µF at a 25 V rating in a φ35 × 100 mm can. It is a polarized, radial can style capacitor designed for general‑purpose power applications that require high bulk capacitance and secure screw‑terminal connections.

Key value comes from its large capacitance in a compact cylindrical package, robust screw‑terminal mounting, established endurance at elevated temperature, and RoHS compliance for broad use in industrial and commercial designs.

Key Features

• Capacitance & Tolerance — 47,000 µF nominal capacitance with ±20% tolerance (at 120 Hz, 20°C), providing substantial energy storage for bulk filtering and smoothing.
• Rated Voltage — 25 V DC rated voltage suitable for low‑voltage power rails and supply stacks.
• Package & Mounting — Radial can with screw terminals (φ35 screw terminal type) for robust electrical connections and easy panel or chassis mounting.
• Operating Temperature — Specified for –40°C to +85°C operation, supporting a wide range of ambient conditions.
• Endurance — Life rating of 5,000 hours at 85°C under specified conditions; capacitance change within ±15% after endurance test when restored to 20°C.
• Leakage Current Limit — After 5 minutes’ application of rated voltage, leakage current is not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20°C).
• Ripple Current Capability — Rated ripple currents of 8.2 A at 120 Hz (low frequency) and 9.43 A at 100 kHz (high frequency) to handle AC components on DC rails.
• Polarized Design — Electrolytic, polarized capacitor for correct orientation in DC circuits.
• RoHS Compliant — Meets RoHS environmental requirements for lead‑restricted applications.

Typical Applications

• General‑Purpose Power Supplies — Provides high bulk capacitance for smoothing and energy storage on 25 V rails in industrial and commercial power supplies.
• DC Link and Bus Stabilization — Large capacitance and rated ripple current support stabilization of DC bus voltages in systems requiring significant charge reservoir.
• Industrial Electronics — Robust screw‑terminal mounting and wide temperature range suit general‑purpose industrial control equipment that needs durable bulk capacitance.

Unique Advantages

• Very high capacitance in a compact can — 47,000 µF in a φ35 × 100 mm package reduces the number of parallel capacitors required for high energy storage.
• Screw‑terminal connections — Provides secure, low‑resistance terminations for high‑current or vibration‑prone installations.
• Documented endurance — 5,000 hours at 85°C with defined limits on capacitance change and leakage current supports predictable long‑term behavior under rated stress.
• Specified leakage behavior — Clear leakage current limits (3√CV µA or 5 mA after 5 minutes at 20°C) simplify design considerations for hold‑up and safety margins.
• Wide operating temperature range — –40°C to +85°C rating enables use across many ambient environments.
• Measured ripple ratings — Separate ripple current figures at 120 Hz and 100 kHz give designers data to size cooling and derating for both low‑ and high‑frequency stress.
