LKS1K821MESZ

The LKS1K821MESZ is a snap‑in terminal aluminum electrolytic capacitor designed for audio equipment and general‑purpose electronic applications. It delivers 820 µF capacitance at an 80 V rated voltage in a compact radial, can‑style snap‑in package and is targeted as a smaller‑sized option for upgrades or replacements of standard parts to improve tone quality.

Engineered for continuous operation across a broad temperature range and compliant with RoHS, this capacitor balances significant capacitance and ripple handling with proven endurance characteristics for reliable performance in board‑mounted power and audio circuits.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 80 V provides bulk energy storage appropriate for filtering and decoupling in higher‑voltage audio and general‑purpose circuits.
• Snap‑In Package — Radial, can‑style snap‑in mounting simplifies PCB assembly and secures the component in place for rugged board environments.
• Audio‑Focused Design — Specified “for audio equipment” and described as smaller‑sized with an effect to tone quality improvement when used as a replacement for small standard products.
• Operating Temperature — Rated for −40 °C to +85 °C to support a wide range of ambient conditions.
• Endurance — Lifetime specified as 1000 hours at 85 °C with defined post‑test limits: capacitance change within ±20%, tan δ up to 200% of initial specified value, and leakage current not exceeding initial specified value.
• Ripple Current — Rated ripple current of 1.4 A at 120 Hz (low frequency) for handling AC ripple in power applications.
• Polarized — Polarized construction for correct orientation in DC circuits.
• Tolerance & Leakage — Capacitance tolerance ±20% (at 120 Hz, 20 °C); leakage current requirement after 5 minutes at rated voltage is not more than 3√(C·V) µA (C in µF, V in V).
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Used as a replacement or upgrade capacitor in audio circuitry to help achieve the stated tone‑quality improvements when substituted for smaller standard parts.
• General‑Purpose Electronics — Suitable where a snap‑in aluminum electrolytic capacitor of 820 µF / 80 V is required for bulk storage, filtering, or decoupling.
• Replacement and Upgrade Projects — Targeted as a smaller‑sized alternative for designers seeking improved audio characteristics by replacing existing small standard capacitors.

Unique Advantages

• Tone‑quality improvement: Explicitly intended for audio equipment and noted for improving tone quality when used as a replacement for small standard products.
• High working voltage: 80 V rating provides headroom for higher‑voltage circuits compared with lower‑voltage electrolytics.
• Robust ripple handling: 1.4 A ripple current rating at 120 Hz supports effective smoothing of AC ripple in power sections.
• Wide temperature capability: −40 °C to +85 °C rating enables deployment across a broad range of ambient conditions.
• Defined endurance: 1000‑hour endurance at 85 °C with specified post‑test limits for capacitance, tan δ, and leakage current supports predictable long‑term performance planning.
• RoHS compliant: Meets current RoHS requirements for restricted substances.
