LKG1K153MKZ

The LKG1K153MKZ is a lug-terminal aluminum electrolytic capacitor designed for audio equipment. It delivers high bulk capacitance in a radial can with solder-lug mounting, intended for applications that require substantial energy storage and low-frequency ripple handling.

Key attributes include 15,000 µF capacitance at 80 V rating, an operating temperature range of -40 °C to 85 °C, and endurance specified for 1,000 hours at 85 °C—making it suitable for high-fidelity audio power supply smoothing and related uses in professional and consumer audio gear.

Key Features

• High Capacitance & Voltage: 15,000 µF rated capacitance with an 80 V rating provides substantial bulk energy storage for power supply smoothing and low-frequency response in audio systems.
• Audio‑Focused Design: Part of the LKG series specified "for audio use" and designed for high-grade audio equipment to prioritize tone quality and fidelity.
• Low‑Frequency Ripple Handling: Low frequency ripple current capability of 8.4 A at 120 Hz supports heavy ripple conditions typical in amplifier power supplies.
• Electrical Losses and Leakage: Tangent of loss angle (tan δ) of 0.25 measured at 20 °C, 120 Hz, and a specified leakage current of 3,280 µA—parameters useful for system-level thermal and bias planning.
• Robust Endurance: Rated for 1,000 hours at 85 °C with capacitance change within ±20% after the endurance test, aligning with long-run operation in demanding audio environments.
• Mechanical & Mounting: Radial can with solder lug (lug terminal) mounting, physical size φ50 × 100 mm (L: 10 × D: 5 cm), and tray packing for production handling.
• Wide Temperature Range: Operating from -40 °C to 85 °C to accommodate a range of installation and operating conditions.
• Compliance: RoHS compliant as specified in product data.

Typical Applications

• High‑fidelity amplifiers: Bulk energy storage and 80 V rating provide stable supply decoupling and low-frequency reserve for power stages in audio amplifiers.
• Professional audio power supplies: High 15,000 µF capacitance combined with 8.4 A ripple capability supports smoothing and filtering under heavy load conditions common in studio and live sound equipment.
• Audio signal conditioning and smoothing: Use in preamplifier and power sections where sustained capacitance and controlled loss characteristics (tan δ) help maintain audio quality.

Unique Advantages

• Substantial bulk energy storage: 15,000 µF at 80 V enables larger energy reserves for extended low-frequency support and improved supply stability.
• Designed for audio fidelity: Series designation and datasheet emphasis on audio use indicate component choices and construction targeted at tone and sound quality priorities.
• High ripple tolerance: 8.4 A ripple rating at 120 Hz reduces heating and voltage excursion risks in power supply stages under dynamic audio loads.
• Engineered endurance: Specified 1,000 hours at 85 °C with defined limits on capacitance and tan δ ensures predictable aging for equipment with extended operating periods.
• Serviceable lug mounting: Solder‑lug radial can simplifies secure mechanical attachment and replacement in rack or chassis-mounted audio equipment.
• Regulatory compliance: RoHS compliance supports use in markets requiring restriction of hazardous substances.
