LNT1J334MSE

The LNT1J334MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, offering large bulk capacitance in a rugged radial can with screw terminals. Designed for general-purpose power applications, this part delivers 330,000 µF (330 mF) at a 63 V rating with a high-temperature operating range up to 105°C.

Built for applications that require substantial energy buffering and high ripple handling, the LNT1J334MSE pairs high capacitance with a durable screw-terminal package and proven endurance characteristics from the LNT family.

Key Features

• High Bulk Capacitance — 330,000 µF (330 mF) provides substantial energy storage for smoothing, buffering, and DC link use in general-purpose designs.
• Rated Voltage — 63 V rated voltage suitable for mid-voltage power systems within the LNT series range.
• Screw-Terminal Package — Radial can with screw terminals for secure, low-resistance connections and straightforward mounting of high-current leads.
• High Ripple Current Capability — Rated ripple current of 26.1 A at 120 Hz and 30.02 A at 100 kHz supports demanding AC ripple and transient duty cycles.
• Wide Temperature Range — Operating temperature range from −40°C to +105°C supports elevated-temperature environments.
• Endurance at High Temperature — Load life specified as 2,000 hours at 105°C for rated ripple current and DC bias (per LNT series conditions).
• Polarized Construction — Polar capacitor design for correct DC polarity operation.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact High-Volume Size — Extended size availability up to φ100 × 250L with this part matching the larger-diameter LNT offerings (documented as φ100 × 250L / L: 25 × D: 10 cm and height seated max 9.843 inch).

Typical Applications

• General-purpose power smoothing — Bulk capacitance for smoothing supply rails and reducing voltage ripple in power supplies and converters.
• Energy buffering — Provides large charge storage for transient support and hold-up in systems that need short-term energy delivery.
• DC link and bus stabilization — Suitable for stabilizing DC bus voltages where high capacitance and ripple tolerance are required.

Unique Advantages

• Large single-unit capacitance: 330,000 µF reduces the number of parallel capacitors required, simplifying BOM and board layout for bulk energy storage.
• High ripple handling: Substantial ripple current ratings at both low and high frequencies help maintain temperature rise and reliability under heavy AC load.
• Robust screw-terminal interface: Facilitates secure, low-impedance connections for high-current applications and simplifies installation and maintenance.
• High-temperature endurance: Rated for operation to 105°C with a specified load life of 2,000 hours at that temperature for the applicable voltage range, supporting demanding thermal environments.
• Part of an extended-range series: Belongs to the LNT family which covers rated voltages from 10 V to 500 V and extended sizes up to φ100 × 250L, enabling consistent design choices across voltage and size needs.
• Regulatory compliance: RoHS conformity aids in meeting regulatory requirements for lead-free designs.
