LKG1C153MESZAK

The LKG1C153MESZAK is a snap-in aluminum electrolytic capacitor from Nichicon's LKG series, engineered for audio equipment where high-fidelity performance is a priority. It delivers large bulk capacitance in a compact snap-in can package for power supply smoothing and decoupling in audio systems and related electronics.

Key value points include a 15,000 µF capacitance at 16 V, a wide operating temperature range from −40 °C to 85 °C, and endurance rated for 1000 hours at 85 °C—combining energy storage, ripple handling, and reliability for audio-grade power systems.

Key Features

• High Capacitance: 15,000 µF nominal capacitance provides substantial bulk energy storage for power supply smoothing and low-frequency stabilization in audio circuits.
• Rated Voltage: 16 V rated working voltage suitable for many low-voltage audio power rails and supply circuits.
• Ripple Handling: Low-frequency ripple current rating of 2.5 A at 120 Hz supports smoothing of rectified power and reduces ripple-related noise in audio paths.
• Loss and Performance: Tangent of loss angle (tan δ) specified at 0.35 (measured at 20 °C, 120 Hz) to characterize AC loss behavior in typical audio operating conditions.
• Reliability and Lifetime: Endurance specified as 1000 hours at 85 °C with defined limits on capacitance change, tan δ, and leakage current after endurance testing.
• Leakage Current: Specified leakage current of 1460 µA provides a quantifiable baseline for standby and quiescent power considerations.
• Package & Mounting: Snap-in radial can package (φ22 × 40 mm length; dimensions L: 4.0 × D: 2.2 cm) for robust board mounting and assembly in power supply modules.
• Temperature Range & Compliance: Operating range −40 °C to 85 °C and RoHS-compliant construction for regulated electronic assemblies.
• Audio-Centric Design: Part of the LKG series developed for audio equipment, prioritizing fidelity and tonal quality in audio designs.

Typical Applications

• High-Fidelity Audio Amplifiers: Bulk supply filtering and reservoir capacitance to support low-noise, stable rails for power amplifiers and preamps.
• Audio Power Supplies: Smoothing rectified AC and reducing low-frequency ripple in dedicated audio power supply modules.
• Professional Audio Equipment: Use in mixers, studio electronics, and other HD audio systems where large capacitance and controlled loss characteristics are required.

Unique Advantages

• Substantial Energy Storage: 15,000 µF provides large capacitance in a compact snap-in form factor to reduce board-level component count for bulk filtering.
• Designed for Audio Quality: LKG series emphasis on high-fidelity sound makes this part appropriate for designs that prioritize tonal integrity.
• Measured AC Characteristics: Specified tan δ at 20 °C/120 Hz and a defined ripple current rating allow predictable behavior in 120 Hz rectified power environments.
• Temperature and Endurance Specified: −40 °C to 85 °C operating range with 1000-hour endurance at 85 °C gives clear, testable reliability parameters for design validation.
• Assembly-Friendly Snap-In Package: Radial snap-in can simplifies mounting for power supply assemblies and reduces installation time compared with discrete leaded parts.
• Clear Marking: Marked with gold-color lettering on a black sleeve for readable identification and polarity inspection during assembly.
