LNT1A333MSEN

The LNT1A333MSEN is a Nichicon LNT-series aluminum electrolytic capacitor in a screw-terminal radial can format. It delivers 33,000 µF capacitance at a 10 V rating and is supplied in a φ35 × 80 mm can with screw terminals for robust electrical and mechanical connections.

Designed for general-purpose power-electronics use, this capacitor combines high bulk capacitance, substantial ripple-current capability and a wide operating temperature range (−40 °C to +105 °C) to support demanding smoothing, filtering and energy-storage roles in industrial and commercial systems.

Key Features

• High Capacitance — 33,000 µF Large bulk capacitance for smoothing and energy-storage requirements where sustained charge reservoir is needed.
• Rated Voltage — 10 V Low-voltage, high-capacitance option for DC-link and low-voltage power rails.
• Screw Terminal Mounting Radial can with screw terminals provides secure, low-impedance connections suitable for repeated service and high-current bus wiring.
• High Ripple-Current Capability Handles 4.8 A at 120 Hz (low frequency) and 5.52 A at 100 kHz (high frequency), supporting applications with significant AC ripple or switching noise.
• Wide Temperature Range and Endurance Operating range of −40 °C to +105 °C with a rated life of 2,000 hours at 105 °C (per series specification for 10 V parts).
• Electrical Characteristics Capacitance tolerance ±20%; tangent of loss angle (tan δ) specified as 0.65 (measured at 20 °C, 120 Hz) and leakage current listed at 1,720 µA.
• Compact Mechanical Footprint Physical size L: 8.0 cm × D: 3.5 cm (φ35 × 80L) provides a high-capacitance solution in a relatively small can for its rating.
• RoHS Compliant Conforms to RoHS environmental requirements.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy buffering on low-voltage DC rails where high capacitance and sustained ripple handling at elevated temperatures are required.
• DC-DC Converter Input/Output — Supports input filtering and output stabilization for converters with substantial low- and high-frequency ripple components, leveraging its 4.8 A (120 Hz) and 5.52 A (100 kHz) ripple ratings.
• Energy Storage Modules and Backup Systems — Provides high-capacitance charge storage for short-term hold-up and transient support in compact assemblies operating up to 105 °C.
• Power Filtering in Industrial Electronics — Suitable for smoothing and decoupling tasks in equipment that demands durable screw-terminal connections and reliable performance across −40 °C to +105 °C.

Unique Advantages

• Large-capacity solution in a compact can: 33,000 µF in a φ35 × 80 mm package minimizes board space for high-energy applications.
• Secure, serviceable connections: Screw terminals enable robust mechanical fastening and low-impedance current paths for high-current or field-serviceable installations.
• Designed for elevated temperature operation: Rated to +105 °C with a 2,000-hour endurance at that temperature for 10 V parts, supporting long-term use in warm environments.
• Dual-frequency ripple handling: Specified ripple current at both 120 Hz and 100 kHz addresses performance needs across mains-rectified and high-frequency switching domains.
• Manufacturing availability: Listed as mass production, providing predictable supply for volume designs.
