LKG1C333MESBAK

The LKG1C333MESBAK is a high-capacitance aluminum electrolytic capacitor in a snap-in radial can designed for audio equipment and related power supply applications. It delivers 33,000 µF at 16 V with snap-in mounting and tray packing for board-level assembly.

Engineered for bulk energy storage and smoothing in audio power chains, the part combines high ripple handling and a usable operating range from −40°C to +85°C with a rated life of 1,000 hours at 85°C.

Key Features

• Bulk Capacitance: 33,000 µF (33 mF) providing substantial energy storage for power-supply smoothing and reservoir applications in audio equipment.
• Rated Voltage: 16 V — suitable for low-voltage audio and power-rail applications requiring large capacitance at moderate voltage.
• Ripple Handling: 3.7 A ripple current (measured at 120 Hz) to support AC ripple in power-supply and amplifier circuits.
• Leakage and Loss: Specified leakage current of 2,170 µA and a tangent of loss angle (tan δ) of 0.57, enabling designers to evaluate standby and dissipation impacts.
• Reliability and Lifetime: Rated for 1,000 hours at 85°C; endurance performance meets the series’ defined criteria for capacitance, tan δ and leakage after the life test.
• Operating Range: −40°C to +85°C to cover typical environmental conditions for professional and consumer audio equipment.
• Mounting and Package: Snap‑in radial can (φ30 × 45 mm length) for secure board retention and mechanical stability; supplied in tray packing.
• Polarized Construction: Polar capacitor suitable for DC smoothing and reservoir duties in power circuits.
• RoHS Compliant: Meets RoHS directive requirements as documented for the LKG series.

Typical Applications

• Professional Audio Power Supplies: Bulk reservoir and smoothing capacitor for amplifier and mixer supply rails where large stored energy is required.
• Power Amplifiers: Supply decoupling and ripple absorption to support stable amplifier performance during dynamic audio loads.
• Studio and Broadcast Equipment: Energy storage and filtering in control consoles, preamps and other rack‑mounted audio electronics.
• Speaker Crossovers and Active Filters: Where large capacitance values are used for low-frequency filtering and transient energy support.

Unique Advantages

• Substantial Energy Capacity: 33,000 µF provides extensive reservoir capability to maintain stable DC rails under dynamic audio demand.
• High Ripple Endurance: 3.7 A ripple rating at 120 Hz reduces voltage modulation and heating in high-current audio power stages.
• Engineered for Audio: Series-level design intent for audio equipment prioritizes fidelity-focused applications.
• Robust Operating Range: −40°C to +85°C and a 1,000‑hour life at 85°C offer predictable performance across typical equipment environments.
• Board-Ready Packaging: Snap-in radial can with tray packing simplifies assembly and secures the component to the PCB.
