LNT1K333MSE

The LNT1K333MSE is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It delivers very high capacitance (33,000 µF) at an 80 V rating in a robust φ76.2 × 100 mm package with a −40 °C to +105 °C operating range.

Its combination of high capacitance, substantial ripple-current capability and 2,000‑hour endurance at 105 °C makes it suited to systems that require bulk energy storage and sustained performance under elevated temperature and continuous ripple loading.

Key Features

• Capacitance & Voltage — 33,000 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance, providing large bulk storage for DC bus and smoothing applications.
• High-Temperature Endurance — Rated for operation from −40 °C to +105 °C with a specified life of 2,000 hours at 105 °C under rated ripple conditions.
• High Ripple Current Capacity — 9.9 A at 120 Hz (low frequency) and 11.38 A at 100 kHz (high frequency) to support heavy AC ripple and dynamic load conditions.
• Leakage & Loss Characteristics — Specified leakage current of 4,870 µA and a tangent of loss angle (tan δ) of 0.3 at 20 °C and 120 Hz for predictable dissipation and performance planning.
• Mechanical & Mounting — Screw terminal, radial can package (φ76.2 × 100 mm) with a robust mounting footprint suited to cabling and bracketed installations.
• Compliance & Availability — RoHS‑compliant construction and mass production status for consistent supply and regulatory adherence.
• Packaging — Supplied in cardboard packing for straightforward handling and storage.

Typical Applications

• Power supply bulk filtering — Large capacitance and high ripple-current ratings support DC bus smoothing and energy storage in commercial and industrial power supplies.
• Motor drives and inverters — 80 V rating and high ripple capability suit intermediate-voltage DC link and filtering duties in motor control and inverter systems.
• Industrial power systems — Extended temperature range and 2,000‑hour endurance at 105 °C allow sustained operation in factory and plant power electronics environments.
• UPS and energy buffering — High capacitance for short-term energy buffering and stabilization of supply rails under transient loads.

Unique Advantages

• Substantial bulk storage: 33,000 µF provides large energy reserve in a single component, reducing the need for parallel arrays.
• Robust ripple handling: Nearly 10–11.4 A ripple capability at representative frequencies minimizes heating and extends service life in ripple-intensive applications.
• High-temperature rated: Qualified for −40 °C to +105 °C operation with 2,000‑hour endurance at 105 °C for reliable performance in elevated-temperature installations.
• Secure screw-terminal mounting: Radial can with screw terminals simplifies electrical connections and mechanical retention for high-current applications.
• Regulatory-ready supply: RoHS compliance and mass production status help assure regulatory conformity and consistent availability.
• Predictable leakage and dissipation: Specified leakage current (4,870 µA) and tan δ (0.3 at 120 Hz, 20 °C) support accurate thermal and standby-loss calculations.
