LNT1J334MSEB

The LNT1J334MSEB is a screw-terminal aluminum electrolytic capacitor offering 330000 µF (330 mF) capacitance at a 63 V rating in a φ100 × 250L can. Designed for general-purpose power applications, its screw-terminal package supports robust, low-impedance connections for high-current systems.

Engineered for elevated-temperature operation, this capacitor is specified for operation up to +105°C with a rated load life of 2000 hours at +105°C. The LNT series also provides an extended voltage range across the family, and the part is RoHS compliant.

Key Features

• High Capacitance (330000 µF): Large bulk energy storage suitable for smoothing, filtering, and bulk decoupling in high-capacity power systems.
• 63 V Rated Voltage: Specified for 63 V DC continuous operation; the LNT series supports rated voltages from 10 V up to 500 V.
• Screw Terminal Package: Radial can with screw terminals provides secure, low-resistance terminations for high-current connections and easy field installation.
• High Temperature Endurance: Rated for operation up to +105°C with a specified load life of 2000 hours at +105°C for this voltage range.
• High Ripple Current Capability: Handles ripple currents of 26.1 A at 120 Hz and 30.02 A at 100 kHz, supporting demanding power-conditioning applications.
• Wide Operating Temperature Range: −40 °C to +105 °C operational range for broad environmental tolerance.
• Polarized Electrolytic Construction: Standard polarized design for DC energy storage and smoothing tasks.
• Capacitance Tolerance and Stability: ±20% tolerance at 120 Hz, 20 °C; endurance criteria ensure capacitance remains within ±20% after the rated life.
• RoHS Compliant: Manufactured in compliance with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply bulk smoothing: High capacitance and substantial ripple-current capability make this part suited for bulk filtering and energy storage in industrial and commercial power supplies.
• DC link / power-conditioning networks: Screw-terminal mounting and high ripple rating support use in DC link circuits and power-conditioning subsystems that require robust terminal connections.
• Uninterruptible power and backup systems: Large capacitance provides bulk energy to support hold-up and short-term backup requirements in UPS and standby power designs.
• High-capacity filtering in large equipment: Useful where substantial bulk capacitance and reliable high-temperature performance are required, such as large drives and power racks.

Unique Advantages

• Substantial bulk energy storage: 330000 µF reduces the need for parallel arrays to achieve large capacitance values, simplifying BOM and layout.
• Robust screw-terminal connections: Facilitates secure, low-impedance terminations for high-current wiring and on-site assembly.
• Designed for high-temperature duty: Rated for operation to +105 °C with a defined 2000-hour load life at that temperature, helping ensure long-term reliability in elevated-temperature environments.
• High ripple-current handling: Specified ripple currents at both 120 Hz and 100 kHz support a range of power-frequency and high-frequency filtering requirements.
• Series flexibility: The LNT family covers a wide voltage range (10 V to 500 V) and large can sizes up to φ100 × 250L, allowing design scalability within the same series.
• Regulatory compliance: RoHS conformity simplifies integration into products needing restricted-substance compliance.
