LNR1E334MSE

The LNR1E334MSE is a screw-terminal aluminum electrolytic capacitor delivering 330,000 µF (330 mF) at 25 V in a radial can package. Designed for general-purpose power applications, it provides high bulk storage and robust ripple handling where large capacitance and reliable DC filtering are required.

Its core architecture pairs a large capacitance with high allowable ripple currents and a screw-terminal mounting system, making it suitable for industrial power supplies, UPS and backup systems, and other power-electronic equipment where secure termination and long endurance are important.

Key Features

• High Capacitance: 330,000 µF (330 mF) provides substantial bulk energy storage for smoothing and hold-up in power systems.
• Rated Voltage and Tolerance: 25 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20°C for predictable design margins.
• High Ripple Current Handling: Supports 24.8 A ripple at 120 Hz and 28.52 A at 100 kHz, enabling effective filtering across low and high frequency components.
• Endurance and Temperature Range: 5,000 hours rated life at 85°C and an operating range of −40°C to +85°C to meet sustained thermal stress requirements.
• Electrical Loss Characteristics: tan δ (DF) of 0.75 at 20°C and 120 Hz for loss-angle specification during AC testing.
• Leakage Current: Specified leakage current up to 5,000 µA after application of rated voltage, supporting predictable standby behavior.
• Screw-Terminal Package: Radial can with screw terminals and standard 3-leg mounting bracket for φ76.2 housings; terminal pitch 31.8 mm and nominal bolt size M5 for secure electrical and mechanical connections.
• Physical Size & Packaging: Body diameter φ76.2 mm × length 120 mm (L: 12.0 cm × D: 7.62 cm); supplied in cardboard packing and available in mass-production status.
• RoHS Compliant: Conforms to RoHS environmental requirements.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and hold-up for large DC bus capacitors to stabilize voltage and reduce ripple under load.
• Uninterruptible Power Supplies (UPS): Energy storage for short-term backup and ride-through, leveraging high capacitance and rated ripple capability.
• Motor Drives and Inverters: DC-link filtering and energy buffering in drives and inverter systems where robust ripple handling is required.
• Power Distribution Modules: Local decoupling and transient absorption in distributed power systems, using screw-terminal mounting for secure installation.

Unique Advantages

• Large energy reservoir: 330,000 µF provides extensive bulk capacitance to reduce voltage sag and extend hold-up time in power systems.
• Strong ripple endurance: 24.8 A @120 Hz and 28.52 A @100 kHz ripple ratings allow reliable operation under continuous AC stress across a wide frequency range.
• Long service life at elevated temperature: 5,000 hours rated life at 85°C supports designs that must operate under sustained thermal load.
• Secure, serviceable termination: Screw-terminal construction with M5 bolt accommodation and standard 3-leg bracket simplifies installation and maintenance in fielded equipment.
• Predictable electrical behavior: Specified tan δ and leakage current figures enable accurate loss and standby current budgeting in system-level design.
• Production-ready supply: Cardboard-packed and listed as mass production status for predictable procurement and inventory planning.
