LKG1V332MESBCK

The LKG1V332MESBCK is a snap-in terminal aluminum electrolytic capacitor from the Nichicon LKG series, tailored for audio equipment. It provides 3.3 mF of bulk capacitance in a radial snap-in can designed for secure PCB mounting and power filtering roles in audio systems.

Key electrical characteristics include a 35 V rated voltage, low loss (tan δ = 0.22 measured at 120 Hz, 20°C), 2.7 A ripple current (120 Hz), and a rated lifetime of 1000 hours at 85°C. The part is RoHS compliant and is supplied in tray packing. Note: this part is marked End of Life.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) rated at 35 V with ±20% tolerance for bulk energy storage and smoothing in power rails.
• Low Loss Performance — tan δ = 0.22 (measurement at 120 Hz, 20°C) to support low-loss operation in audio signal and power applications.
• Ripple Handling — 2.7 A ripple current specified at 120 Hz for acceptance of AC stress in power supply filtering.
• Leakage Current — Specified leakage current: 1010 µA, suitable for design margining and end-of-line verification.
• Mechanical & Mounting — Snap-in radial can (φ30 × 40 mm; L: 4.0 cm × D: 3.0 cm) for robust board retention and easy assembly from the component side; supplied in tray packing.
• Temperature & Reliability — Operating range −40°C to +85°C with endurance: 1000 hours at 85°C under rated voltage.
• Polarized — Polar capacitor intended for DC power and audio power applications.
• Environmental — RoHS compliant.

Typical Applications

• High-fidelity audio power supplies — Bulk smoothing and decoupling for amplifier and preamplifier rails to support stable supply under varying load.
• Audio amplifier stages — Energy reservoir for power amplifiers where sustained capacitance and ripple handling are required.
• Active crossover networks and filters — Low-loss capacitance for low-frequency coupling and filtering in speaker systems.
• Analog audio circuitry — Power conditioning for analog front-ends where low tan δ supports cleaner power delivery.

Unique Advantages

• High bulk capacitance: 3.3 mF provides significant energy storage for low-frequency decoupling and reservoir needs in audio power rails.
• Audio-focused design: LKG series is specified for audio use and is described as giving priority to high-fidelity sound quality, supporting designs where sonic performance matters.
• Robust ripple capability: 2.7 A ripple rating at 120 Hz reduces stress on upstream regulators and improves stability under dynamic audio loads.
• Secure snap-in mounting: Radial snap-in can offers strong mechanical retention for through-hole power boards and easier assembly handling.
• Thermal endurance: Rated for 1000 hours at 85°C, enabling predictable aging characteristics in thermal-stressed audio equipment.
• Regulatory compliance: RoHS compliant for environmentally conscious designs and manufacturing requirements.
