LNT1E333MSE

The LNT1E333MSE is a Nichicon LNT series aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It provides high bulk capacitance (33,000 µF) at a 25 V rating with screw terminals for secure, low-resistance connections in industrial and power-supply environments.

Key value comes from its combination of large capacitance, high ripple-current capability, broad operating temperature range (−40°C to +105°C) and a confirmed endurance rating at elevated temperature, making it suitable for systems that require robust energy buffering and smoothing.

Key Features

• High Capacitance: 33,000 µF (33 mF) bulk capacitance for effective energy storage and smoothing in power rails.
• Rated Voltage: 25 V DC rating suitable for low-voltage power systems and DC bus applications.
• Mounting & Termination: Screw terminal radial can package provides secure, serviceable connections for high-current installations.
• Ripple Current Capability: 6.2 A at 120 Hz and 7.13 A at 100 kHz, supporting significant AC ripple on DC rails.
• Temperature Range & Endurance: Operates from −40°C to +105°C with a life/endurance rating of 2000 hours at 105°C under rated ripple and bias conditions.
• Leakage Current & Tolerance: Specified leakage current of 2720 µA and capacitance tolerance of ±20% (120 Hz, 20°C).
• Polarized Construction: Polarized electrolytic design for correct DC orientation in circuits.
• Compliance & Packaging: RoHS compliant and supplied in cardboard packing; product is in mass production.

Typical Applications

• Power Supply Filtering: Bulk smoothing and decoupling on low-voltage DC rails where high capacitance is required to reduce ripple and stabilize output.
• Energy Buffering: Hold-up and energy storage in industrial power modules and backup circuits that need large charge reservoirs.
• Power Electronics: Bulk capacitance for inverter controls, motor drives, and converters where screw-terminal mounting simplifies high-current connections and serviceability.
• Industrial Controls and UPS: Smoothing and transient absorption in control cabinets and uninterruptible power supplies operating across a wide temperature range.

Unique Advantages

• Large Stored Energy: 33,000 µF provides substantial energy density for smoothing and buffering, reducing the need for parallel components.
• High Ripple Handling: Rated ripple currents (6.2 A @120 Hz, 7.13 A @100 kHz) permit reliable operation under significant AC stress on DC buses.
• Rugged Thermal Performance: −40°C to +105°C operating range and 2000-hour endurance at 105°C deliver predictable behavior in demanding thermal environments.
• Secure Screw-Terminal Interface: Screw terminals simplify heavy-current connections and maintenance compared with leaded or solder-only options.
• Manufacturing-Ready Supply: RoHS compliance, cardboard packing, and mass-production status support volume procurement and assembly workflows.
• Clear Specification Set: Defined leakage current (2720 µA) and ±20% tolerance allow designers to budget margins and predict in-circuit performance.
