LNR2A333MSEB

The LNR2A333MSEB is a screw-terminal aluminum electrolytic capacitor designed to deliver large bulk capacitance and robust ripple-handling in a radial can with screw terminals. With a rated capacitance of 33,000 µF at 100 V and polarization for DC applications, it is intended for general-purpose use where high energy storage and secure mechanical mounting are required.

Key value propositions include high ripple current capability at both low and high frequencies, a wide operating temperature range from –40 °C to 85 °C, and endurance validated to 5,000 hours at 85 °C, making it suitable for demanding industrial and power-electronics environments that require durable bulk capacitance.

Key Features

• Bulk Capacitance & Voltage — 33,000 µF nominal capacitance rated at 100 V, providing substantial energy storage for DC systems.
• High Ripple Current Handling — Low-frequency ripple current of 10,000 mA (10 A) at 120 Hz and high-frequency ripple current of 11,500 mA (11.5 A) at 100 kHz, supporting effective smoothing under continuous ripple conditions.
• Temperature Range & Endurance — Rated for operation from –40 °C to 85 °C with an endurance specification of 5,000 hours at 85 °C when subjected to D.C. bias plus rated ripple current.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20 °C, for predictable sizing and design margining.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current is specified as not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C), to aid in power budgeting and safety considerations.
• Durable Screw-Terminal Package — Radial can with screw terminals (φ51 body diameter, L: 140 mm) and standard bracket mounting for secure electrical and mechanical connections in panel- and chassis-mounted systems.
• Shelf Life & Reliability — Shelf life characterization includes storage at 85 °C for 1,000 hours with subsequent voltage treatment per JIS C 5101-4; capacitance, tan δ and leakage requirements are defined to ensure long-term reliability.
• RoHS Compliant — Conforms to RoHS status as provided in product data.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing in DC power supplies where large capacitance and high ripple capability are required.
• Industrial power electronics — Applications requiring secure screw-terminal mounting and sustained ripple performance at elevated temperatures.
• Backup and hold-up circuits — Providing large capacitance for short-term energy hold-up in systems that must ride through brief power interruptions.

Unique Advantages

• High bulk energy capacity: 33,000 µF at 100 V supplies significant stored charge for smoothing and hold-up functions.
• Dual-frequency ripple performance: Specified ripple currents at 120 Hz and 100 kHz (10 A and 11.5 A) let designers account for both low- and high-frequency ripple in their thermal and lifetime calculations.
• Robust mounting and electrical connection: Screw terminal package and radial can construction provide reliable mechanical fastening and low-resistance current paths for high-current applications.
• Validated endurance at elevated temperature: 5,000-hour endurance at 85 °C under D.C. bias plus rated ripple current supports predictable long-term operation.
• Clear leakage and tolerance specifications: Defined leakage current formula and ±20% capacitance tolerance enable accurate system-level planning and derating.
• RoHS compliance: Meets environmental compliance requirements indicated in the product data.
