LKS1K182MESA

The LKS1K182MESA from Nichicon is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and general-purpose power applications. It delivers 1.8 mF capacitance at an 80 V rating in a compact, radial can snap-in package.

Optimized for smaller-sized designs, this component is intended for use where replacing a smaller standard capacitor can contribute to perceived tone-quality improvement in audio circuits. The part is RoHS compliant and engineered for operation from −40°C to +85°C.

Key Features

• Capacitance & Voltage — 1.8 mF nominal capacitance with an 80 V rated voltage, suitable for higher-voltage filter and coupling roles in audio and general-purpose power circuits.
• Snap-in Radial Can Package — Snap-in mounting type in a radial, can-style package for secure PCB retention and straightforward assembly into power and audio chassis.
• Compact Size — Physical dimensions of 2.5 cm × 2.5 cm (L × D) enable smaller board footprints where space is limited.
• Temperature Range — Rated for operation from −40°C to +85°C to support a wide range of ambient conditions.
• Endurance — Designed for 1,000 hours at 85°C with specified limits on capacitance change, tan δ, and leakage current after endurance testing.
• Polarized Electrolytic — Polarized construction for typical DC filtering and decoupling applications; leakage and tan δ specifications are provided per datasheet guidance.
• Low-Frequency Ripple Handling — Rated ripple current of 2.25 A at 120 Hz for effective low-frequency smoothing in power supplies and audio power stages.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Amplifiers — Use for power supply smoothing and coupling where improved tonal characteristics are desired by replacing smaller standard capacitors.
• Power Supply Filters — Bulk filtering and smoothing in higher-voltage DC rails within audio and general-purpose electronics.
• Consumer Audio Equipment — Suitable for use in compact audio equipment designs that require a snap-in, serviceable capacitor with a small footprint.

Unique Advantages

• Audio-focused Design: Marketed specifically for audio equipment with noted tone-quality improvement when replacing smaller standard parts, helping designers target sound performance upgrades.
• High Voltage Capability: 80 V rating enables use in higher-voltage sections of audio and power circuitry without upsizing the capacitor footprint significantly.
• Secure Snap-in Mounting: Snap-in terminals provide robust mechanical retention for chassis-mounted and high-vibration environments compared with standard radial leads.
• Compact Footprint: Small 2.5 cm × 2.5 cm dimensions support space-constrained layouts while still providing substantial capacitance (1.8 mF).
• Validated Endurance: Specified 1,000-hour endurance at 85°C with defined limits on capacitance change, tan δ, and leakage current for predictable life performance.
• Regulatory Compliance: RoHS compliance for use in designs targeting restricted-substance requirements.
