LNR1A684MSEN

The LNR1A684MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNR series, offering very high capacitance in a robust radial can package. Engineered for general-purpose power systems, it provides bulk energy storage and smoothing at a rated voltage of 10 V with a capacitance of 680000 µF (680 mF).

Key value comes from its combination of extreme capacitance, high ripple-current capability, long endurance at elevated temperature, and a wide operating temperature range, making it suitable for demanding power applications that require reliable bulk capacitance and stable performance over time.

Key Features

• High Capacitance — 680000 µF (680 mF) provides substantial bulk energy storage for power smoothing and hold-up functions.
• Rated Voltage — 10 V nominal rating suitable for low-voltage power rails and DC bus applications where large capacitance is required.
• Screw Terminal Mounting — Radial can with screw terminals enables secure mechanical and electrical connections for high-current installations.
• Ripple Current Handling — Rated ripple current of 22.8 A at 120 Hz and 26.22 A at 100 kHz supports sustained AC ripple duty in power circuits.
• Endurance and Stability — Specified endurance of 5000 hours at 85°C with capacitance change within ±15% and leakage current remaining within initial specified limits after test.
• Operating Range — Designed to operate from −40°C to +85°C, matching the LNR series category temperature for 10 V devices.
• Measured Leakage — Initial leakage current specified at 5000 µA (5 mA), consistent with series leakage criteria.
• Package & Mounting Options — φ76.2 mm diameter × 120 mm length radial can; standard provision for 3-leg mounting bracket on larger diameters per series drawing.
• RoHS Compliant — Manufactured to meet RoHS environmental requirements.

Typical Applications

• General-Purpose Power Systems — Bulk energy storage and smoothing on low-voltage DC rails where very high capacitance is required.
• Power Supply Hold-Up — Provides temporary energy reserve and ripple suppression in power supply and DC bus applications subject to sustained ripple currents.
• Industrial Electronics — Robust screw-terminal mounting and high ripple capability make it suitable for industrial power modules and control equipment that need reliable bulk capacitance.

Unique Advantages
