LKS2A332MESC

The LKS2A332MESC is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and general-purpose power filtering. It delivers 3.3 mF (3300 μF) capacitance at a 100 V rating in a smaller-sized, radial can snap-in package suited for board-mounted power applications.

Engineered to serve as a replacement for smaller standard products, this capacitor is intended to contribute to tone-quality improvement in audio designs while offering predictable endurance characteristics and RoHS compliance.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 μF) rated at 100 V with a capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Snap-in Radial Can — Snap-in terminal mounting for secure board attachment in power-supply and chassis-mounted assemblies.
• Size & Mechanical — Compact form factor: L × D = 3.5 × 3.5 cm; seated height maximum specified as 1.378 inch for layout planning.
• Operating Temperature Range — Specified for operation from −40 °C to +85 °C.
• Endurance — Rated lifetime of 1000 hours at 85 °C; after the test, capacitance change is within ±20%, tan δ remains within 200% of initial, and leakage current remains at or below the initial specified value.
• Leakage Current Specification — After 5 minutes’ application of rated voltage at 20 °C, leakage current is specified as not more than 3√CV (μA), where C is capacitance (μF) and V is voltage (V).
• Ripple Current — Rated ripple current of 3.6 A at 120 Hz for AC ripple handling in power applications.
• Polarized — Electrolytic polarity must be observed in circuit installation.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• Audio Amplifiers — Bulk filtering and power-supply decoupling where replacing smaller standard capacitors can help improve perceived tone quality.
• Power Supply Filtering — Smoothing and energy storage in linear and switch-mode power supplies requiring 100 V rated bulk capacitance.
• General-Purpose Industrial Electronics — Board-mounted energy storage and ripple suppression in equipment operating within −40 °C to +85 °C.

Unique Advantages

• Designed for audio upgrades — Intended as a smaller-sized replacement option to improve tone quality when upgrading from small standard capacitors.
• High-voltage bulk capacitance — 100 V rating combined with 3.3 mF capacitance enables use in higher-voltage smoothing and energy-storage roles.
• Robust ripple handling — 3.6 A ripple current at 120 Hz supports effective AC ripple management in power-supply applications.
• Predictable lifetime and endurance — 1000 hours at 85 °C with defined end-of-test limits for capacitance, tan δ, and leakage current simplifies reliability planning.
• Board-ready snap-in package — Radial snap-in can offers a secure mechanical and electrical connection for chassis and PCB installations.
• Regulatory compliance — RoHS conformity supports use in designs targeting restricted-substance compliance.
