LKS1E332MESZ

The LKS1E332MESZ is an aluminum electrolytic, snap-in terminal capacitor from Nichicon’s LKS series designed for audio equipment. It combines a compact snap-in can package with specifications targeted for power-supply filtering and tone-quality improvements when replacing smaller standard parts.

Key electrical and mechanical characteristics include a capacitance of 3.3 mF (3300 µF) at 25 V, polarized construction, and RoHS compliance. The part is specified for operation between −40 °C and +85 °C with a rated endurance of 1000 hours at 85 °C.

Key Features

• Capacitance & Rated Voltage — 3.3 mF (3300 µF) nominal capacitance at 25 V, suitable for bulk energy storage and smoothing in audio power supplies.
• Snap‑in Radial Can — Snap-in terminal mounting for secure board installation and reliable mechanical retention in chassis-mounted or PCB applications.
• Compact Dimensions — 22 × 20 mm case footprint (L × D) with a seated height maximum of 20 mm, offering a smaller-sized option for space-constrained audio designs.
• Audio‑focused Performance — LKS series description notes improved tone quality when replacing smaller standard products, aimed at audio equipment upgrades.
• Ripple Current & Loss — Rated ripple current of 1.40 A (120 Hz) and tan δ of 0.30 (measured at 120 Hz, 20 °C) for effective AC filtering in power stages.
• Temperature and Endurance — Operating range −40 °C to +85 °C with endurance specified as 1000 hours at 85 °C under rated voltage; capacitance change and leakage limits are defined for post-endurance performance.
• Leakage Current Specification — Leakage current after 5 minutes at rated voltage (20 °C) is specified as not more than 3√(C·V) µA, where C is rated capacitance (µF) and V is voltage (V).
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Amplifiers — Bulk filtering and reservoir capacitance in amplifier power supplies, with documented tone-quality improvement when replacing smaller standard parts.
• Consumer Audio Systems — Power supply smoothing in receivers, integrated systems, and hi-fi equipment requiring compact snap-in capacitors.
• Audio Signal Power Rails — Decoupling and energy storage on low-voltage audio power rails where polarized electrolytic capacitors are used.

Unique Advantages

• Compact footprint for tighter layouts: 22 × 20 mm case size and snap-in mounting enable space savings compared with larger radial cans.
• Designed for audio upgrades: Series specification highlights an audible tone-quality improvement when used as a replacement for smaller standard products.
• Robust ripple handling: 1.40 A ripple current (120 Hz) supports effective AC filtering in low-frequency power stages.
• Specified endurance: 1000 hours at 85 °C under rated voltage provides a defined reliability expectation for design planning.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements in commercial electronics.
