LKS1E153MESA

The LKS1E153MESA is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LKS series, designed for audio equipment and general-purpose circuits. It provides 15 mF capacitance at a 25 V rating in a compact snap-in radial can, aimed at improving tonal quality when replacing smaller standard capacitors.

Key electrical and mechanical attributes include a working temperature range of -40 to +85 °C, a rated ripple current of 3 A at 120 Hz, and endurance specified as 1000 hours at 85 °C.

Key Features

• Capacitance & Voltage 15 mF (15,000 μF) rated at 25 V with ±20% tolerance, suitable for bulk energy storage and smoothing in low-voltage circuits.
• Package & Mounting Snap-in radial can (snap-in terminal type) for secure PCB mounting and ease of assembly in chassis or board-mounted power sections.
• Audio-focused Tone Improvement Specifically noted for use in audio equipment; intended to provide a tonal-quality improvement when replacing smaller standard products.
• Temperature & Lifetime Rated for operation from -40 to +85 °C with an endurance specification of 1000 hours at 85 °C.
• Ripple Current & Loss Rated ripple current of 3 A at 120 Hz and a specified tangent of loss angle (tan δ) of 0.30 for this product configuration.
• Leakage Current Specification Leakage current after 5 minutes at rated voltage and 20 °C is specified as not more than 3√CV (μA), where C is capacitance (μF) and V is voltage (V).
• RoHS Compliant Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size & Tolerance Compact dimensions (approx. L: 4.0 cm × D: 2.5 cm) and ±20% capacitance tolerance for predictable design margins.

Typical Applications

• Audio Equipment — Replacement or upgrade in power supply and output stages where improved tonal quality is desired by moving up from smaller standard capacitors.
• Power Supply Filtering — Bulk smoothing and decoupling for low-voltage power rails in general-purpose electronic equipment.
• Amplifier Power Stages — Energy reservoir and ripple handling in amplifier power supplies requiring 15 mF at 25 V and a 3 A ripple rating at 120 Hz.

Unique Advantages

• Audio-oriented design: Specified for audio equipment with a documented benefit in tone quality when replacing smaller capacitors.
• Compact snap-in format: Snap-in radial can provides a secure mechanical mount and a smaller footprint compared to larger, standard snap-in parts.
• High ripple capability: 3 A ripple current rating at 120 Hz supports demanding smoothing tasks in power supplies and amplifier circuits.
• Wide operating temperature: Rated for -40 to +85 °C, enabling use across a broad range of ambient conditions.
• Endurance assurance: Endurance tested to 1000 hours at 85 °C, with defined limits for capacitance change, tan δ, and leakage current after test.
• Regulatory compliance: RoHS-compliant construction for use in products requiring restricted-substance adherence.
