LKG1H152MESZBK

The LKG1H152MESZBK from Nichicon is a snap-in, radial can aluminum electrolytic capacitor specifically developed for audio equipment. It delivers 1.5 mF (1500 µF) capacitance at a 50 V rating with polarized construction and is part of Nichicon's LKG series tailored for high-grade audio applications.

Engineered for audio circuitry where bulk energy storage, smoothing and low-frequency ripple handling are required, this capacitor combines an audio-focused design ethos with practical mounting and reliability characteristics for production assemblies.

Key Features

• Capacitance & Voltage – 1.5 mF (1500 µF) rated at 50 V, providing bulk energy storage for audio power rails and smoothing duties.
• Tolerance & Electrical Loss – ±20% capacitance tolerance and specified tan δ of 0.3, supporting predictable performance in filter and reservoir applications.
• Audio-focused Grade – Part of the LKG series designed for audio equipment; the BK code aligns this unit with the TYPE-II grade intent for tonal performance in high-fidelity designs.
• Mounting & Package – Snap-in radial can package for secure chassis or PCB-mounted installations with simplified mechanical assembly.
• Operating Range & Lifetime – Rated for operation from −40 °C to +85 °C with endurance specified as 1000 hours at 85 °C, enabling reliable service in typical audio-enclosure environments.
• Ripple Handling – Low-frequency ripple current rating of 1.8 A at 120 Hz, suitable for smoothing and power-supply ripple reduction in amplifier and preamplifier circuits.
• RoHS Compliant – Conforms to RoHS directive requirements for materials compliance.
• Physical Size – Compact form factor with dimensions approximately L: 30 mm × D: 22 mm and a seated height of 1.181 inches, facilitating placement in constrained audio assemblies.

Typical Applications

• High‑fidelity amplifiers – Bulk smoothing and power-rail decoupling to support consistent audio output and low-frequency stability.
• Audio power supplies – Reservoir capacitance and ripple suppression in linear or discrete power-supply stages.
• Preamp and filter circuits – Energy storage and filtering where audio transparency and stable low-frequency response are required.

Unique Advantages

• Audio-oriented design: LKG series heritage and TYPE‑II (BK) grade alignment emphasize tonal quality considerations useful in high-grade audio equipment.
• Practical ripple capacity: 1.8 A at 120 Hz ripple rating supports effective smoothing in audio power stages, reducing hum and low-frequency modulation.
• Robust thermal profile: −40 °C to +85 °C operating range with 1000-hour endurance at 85 °C for predictable life under typical audio operating conditions.
• Secure snap-in mounting: Radial, snap-in can simplifies installation and mechanical retention in chassis or PCB assemblies.
• Regulatory compliance: RoHS compliance helps meet environmental directives for assembly-level regulatory requirements.
