LNT2H331MSEFBB

The LNT2H331MSEFBB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose applications that require high voltage and elevated temperature operation. This part provides 330 µF capacitance at a 500 V rating, polarized construction, and screw-terminal mounting for secure electrical connections.

Engineered for robust thermal and ripple performance, the LNT series supports extended voltage ranges up to 500 V and is specified for operation to +105°C, making this part suitable where sustained high-voltage filtering and energy buffering are required in general-purpose systems.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 500 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High-temperature endurance: Rated for operation up to 105°C with a specified load life of 2000 hours at 105°C for 500 V parts.
• Ripple current handling: Specified ripple current performance of 2.7 A at 120 Hz and 3.78 A at 100 kHz to support smoothing and decoupling under AC stress.
• Mounting & package: Screw-terminal radial can package provides secure mechanical and electrical connections for higher-current or removable installations.
• Polarized design: Polar capacitor construction suitable for DC bias applications.
• RoHS compliance: Conforms to the RoHS directive as indicated for the LNT series.
• Size: Physical dimensions listed as L: 8 × D: 5.1 cm for board- or chassis-layout planning.

Typical Applications

• General-purpose high-voltage systems: Use where a 500 V rated electrolytic capacitor is required for high-voltage filtering or energy storage in general-purpose equipment.
• High-temperature environments: Applications that require operation up to +105°C and sustained performance over extended elevated-temperature lifetimes.
• Screw-terminal installations: Systems that benefit from secure, serviceable screw-terminal connections for power bus or bulk capacitance.

Unique Advantages

• 500 V rated capability: Supports high-voltage designs without series-parallel capacitor arrangements, simplifying BOM and layout.
• Designed for elevated temperature life: Load life specified at 2000 hours at 105°C for 500 V parts, providing predictable long-term performance under thermal stress.
• Measured ripple performance: Clear ripple current ratings at both low and high frequencies (2.7 A at 120 Hz, 3.78 A at 100 kHz) to help size capacitors for filtering and ripple management.
• Screw-terminal radial can: Robust mechanical termination for reliable connections in removable or high-current assemblies.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
• Compact footprint for its class: 330 µF at 500 V in a radial screw-terminal can offers dense energy storage for constrained spaces (L: 8 × D: 5.1 cm).
