LKS1K332MESB

The LKS1K332MESB from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LKS series, designed for general-purpose power filtering and bulk energy storage. It provides 3.3 mF capacitance at an 80 V rating in a compact φ30 × 30 mm radial, can-style snap-in package.

Built for applications that require high-capacitance filtering with robust ripple handling, this part combines a wide operating temperature range and defined endurance characteristics for reliable operation in industrial and audio-related equipment.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance for bulk energy storage and decoupling.
• Snap-in Radial Package — Radial, can-style snap-in mounting (φ30 × 30 mm) suitable for secure chassis or board retention and high-current paths.
• Ripple Current Handling — Rated for 3.0 A ripple current at 120 Hz, supporting applications with significant AC ripple on DC bus lines.
• Leakage Current — Specified leakage current of 1540 µA (measured conditions per product data), enabling predictable quiescent behavior in power designs.
• Temperature & Endurance — Operating range of −40°C to +85°C with a rated lifetime of 1000 hours at 85°C, meeting defined endurance requirements after high-temperature stress.
• Polarized Electrolytic — Polarized device intended for DC applications where correct polarity is observed.
• RoHS Compliant — Manufactured to meet RoHS requirements for environmental compliance.
• Packaging — Supplied in tray packing for handling and assembly efficiency. Product currently listed with end-of-life status.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling on DC rails in a variety of electronic equipment.
• Audio equipment — Series LKS is specified for smaller-sized, audio-oriented applications where high-capacitance filtering is required.
• Industrial power supplies — Energy storage and ripple suppression on intermediate DC link circuits and power converters.
• Control and instrumentation — Bulk decoupling in general-purpose control electronics operating within −40°C to +85°C.

Unique Advantages

• High-voltage capability: 80 V rating allows use on higher-voltage DC rails without series stacking.
• Large capacitance in compact footprint: 3.3 mF in a φ30 × 30 mm snap-in can provides substantial energy storage where board or chassis space is constrained.
• Defined ripple performance: 3.0 A ripple current rating at 120 Hz supports designs with significant AC ripple requirements.
• Endurance-backed reliability: 1000 hours at 85°C endurance rating provides predictable aging and performance after high-temperature exposure.
• RoHS-compliant manufacturing: Conforms to RoHS requirements for environmental compliance in modern electronic assemblies.
