LKS1K102MESY

The LKS1K102MESY is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKS series designed for audio equipment and general‑purpose electronic uses. It provides a polarized, radial can package with a compact footprint intended as an upgrade from smaller standard parts to help improve tone quality in audio applications.

Key attributes include a 1 mF capacitance at an 80 V rating, snap‑in mounting for robust panel or chassis installation, and RoHS compliance (2011/65/EU, (EU)2015/863).

Key Features

• Electrical Performance — 1 mF (1000 μF) capacitance with an 80 V rated voltage and ±20% tolerance, suitable for applications requiring substantial bulk capacitance at elevated voltage.
• Ripple and Loss Characteristics — Rated ripple current of 1.55 A at 120 Hz and loss characteristics (tan δ) measured at 120 Hz, 20°C for predictable AC performance in filtering and decoupling roles.
• Mounting & Package — Snap‑in, radial can package designed for secure chassis or PCB mounting; compact physical size of approximately 2.5 × 2.0 cm (L × D) for space‑constrained designs.
• Operational Temperature & Endurance — Operating temperature range of −40°C to +85°C with a specified endurance of 1000 hours at 85°C under rated voltage, ensuring defined long‑term performance under thermal stress.
• Leakage and Reliability — Leakage current guaranteed not more than 3√CV (μA) after 5 minutes at 20°C (C = rated capacitance in μF, V = voltage in V); end‑of‑life limits specify capacitance change within ±20% and leakage current ≤ initial value after endurance testing.
• Compliance & Identification — RoHS compliant and marked with silver lettering on a black sleeve for clear identification.

Typical Applications

• Audio Equipment — Used as an upgrade replacement to improve tone quality in amplifiers, preamplifiers, and other audio subsystems by moving from smaller standard capacitors to this larger‑capacitance, snap‑in part.
• General‑Purpose Electronics — Bulk filtering, energy storage, and smoothing in a wide range of general applications that require a polarized aluminum electrolytic with snap‑in mounting.
• Component Upgrades & Retrofits — Replacement part for designs looking to increase capacitance and ripple handling while retaining a compact radial, snap‑in form factor.

Unique Advantages

• Tone‑quality improvement when used as a replacement — Specifically called out for audio applications where replacing smaller standard parts can yield audible improvements in tone.
• High voltage rating — 80 V nominal rated voltage supports circuits that require elevated DC bus levels without changing capacitor topology.
• Compact snap‑in package — Radial, snap‑in can construction offers a space‑efficient solution that simplifies mechanical installation in chassis or PCBs.
• Defined endurance specification — 1000 hours at 85°C endurance with clear post‑test limits for capacitance, tan δ and leakage current, allowing predictable lifecycle planning.
• Measurable leakage specification — Leakage current limit defined by 3√CV (μA) after 5 minutes at 20°C, enabling designers to verify conformity during qualification.
• Regulatory compliance — RoHS compliance (2011/65/EU, (EU)2015/863) supports regulatory requirements for restricted substances.
