LNT1J333MSEN

The LNT1J333MSEN is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNT series, offering 33,000 µF capacitance at a 63 V rating in a radial can with screw terminals (φ63.5 × 100 mm). It is designed for general-purpose applications that require large bulk capacitance, DC bias handling and high ripple-current capability.

Key performance attributes include rated capacitance of 33 mF, a usable temperature range from −40°C to +105°C, rated endurance of 2000 hours at 105°C under rated ripple, and robust ripple-current specifications for both low and high frequency operation.

Key Features

• High Capacitance — 33,000 µF rated capacitance provides substantial bulk energy storage and decoupling in power systems.
• 63 V Rated Voltage — Suitable for applications requiring up to 63 V DC working voltage.
• Screw-Terminal Package — Radial can with screw terminals simplifies secure, low-impedance connections for high-current paths; terminal hardware nominally M5 for the φ63.5 size.
• Wide Operating Temperature — Rated for −40°C to +105°C to support elevated ambient conditions and thermal stress.
• Endurance at Elevated Temperature — 2000 hours life at 105°C under rated ripple current, per series endurance specification for the 10–250 V range.
• High Ripple-Current Capability — 9.4 A at 120 Hz (low frequency) and 10.81 A at 100 kHz (high frequency) to handle sustained AC ripple currents.
• Leakage and Dissipation — Specified leakage current of 4,320 µA and tan δ (DF) of 0.3 measured at 20°C, 120 Hz.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20°C.
• RoHS Compliant — Conforms to applicable RoHS directives.

Typical Applications

• Power supply bulk filtering — Large capacitance and high ripple-current ratings make it suitable for bulk DC filtering in general-purpose power systems.
• Energy buffering — Provides bulk energy storage where high capacitance and secure screw-terminal connections are required.
• Industrial and general electronic equipment — Robust temperature range and endurance support use in equipment that subjects capacitors to elevated operating temperatures and continuous ripple stress.

Unique Advantages

• Large stored energy per package: 33,000 µF at 63 V delivers significant bulk capacitance for smoothing and buffering tasks.
• Dual-frequency ripple handling: Rated ripple currents of 9.4 A (120 Hz) and 10.81 A (100 kHz) allow reliable performance across low and high frequency ripple environments.
• Mechanical reliability of screw terminals: Radial can with screw-terminal mounting and M5 nominal bolt sizing for φ63.5 enables robust connections for high-current bus wiring.
• High-temperature endurance: Rated 2000 hours at 105°C under rated ripple conditions, supporting designs that operate at elevated temperatures.
• Clear electrical limits: Specified leakage current (4,320 µA), tan δ (0.3 at 20°C, 120 Hz) and ±20% tolerance enable predictable electrical design margins.
• Regulatory compliance: RoHS compliance simplifies use in regions requiring restricted substances conformance.
