LNT1H683MSEN

The LNT1H683MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series. It provides 68,000 µF capacitance at a 50 V rated voltage in a φ63.5 × 120 mm can with radial screw terminals for secure, high-current connections.

Designed for general-purpose power applications, this part offers high ripple current capability, a wide operating temperature range of −40 °C to +105 °C, and a specified endurance of 2,000 hours at 105 °C for the 10–250 V range.

Key Features

• Capacitance & Rated Voltage — 68,000 µF nominal capacitance, rated for 50 V with ±20% tolerance at 20 °C, 120 Hz.
• High Ripple Current — Low-frequency ripple current 12.8 A (120 Hz) and high-frequency ripple current 14.72 A (100 kHz), supporting heavy AC ripple conditions.
• Temperature & Endurance — Operating temperature range −40 °C to +105 °C; rated life 2,000 hours at 105 °C when subjected to rated ripple current and DC bias (per LNT series specification for 10–250 V).
• Electrical Losses & Leakage — Tangent of loss angle (tan δ) 0.35 measured at 20 °C, 120 Hz; leakage current specified at 5,000 µA.
• Screw-terminal, Radial Can Package — φ63.5 × 120 mm can with screw terminals suitable for M5 nominal bolt mounting (per LNT series dimensional table for φ63.5).
• Compliance & Packaging — RoHS compliant; supplied in cardboard packing and listed as mass production status.

Typical Applications

• General-purpose bulk energy storage — Large capacitance and high ripple current handling make it suitable for bulk smoothing and energy buffering in general-purpose power designs.
• Power supply filtering — High ripple current ratings at both low and high frequencies support suppression of AC ripple on DC rails.
• High-temperature environments — Rated for operation to +105 °C with specified endurance, appropriate where elevated ambient temperatures occur.

Unique Advantages

• Very large capacitance at 50 V — 68,000 µF provides substantial bulk storage in a single radial can, reducing the need for multiple smaller capacitors.
• High ripple-current capability — 12.8 A (120 Hz) and 14.72 A (100 kHz) ratings support demanding AC ripple conditions across a range of frequencies.
• 105 °C endurance rating for 10–250 V range — Specified 2,000-hour life at 105 °C under rated conditions per the LNT series specification for this voltage class.
• Screw-terminal mounting with M5 nominal bolt — Radial screw terminals and documented terminal dimensions for φ63.5 simplify mechanical integration and secure connections.
• Clear electrical characterization — Provided tan δ (0.35 at 20 °C, 120 Hz) and leakage current (5,000 µA) figures support accurate thermal and electrical design calculations.
• RoHS compliant and production-ready — Meets RoHS requirements and is listed as mass production, facilitating procurement and manufacturing planning.
