LKS1V472MESY

The LKS1V472MESY is an aluminum electrolytic capacitor in Nichicon’s LKS series featuring a snap‑in radial can and polarized terminals, designed specifically for audio equipment and general-purpose circuits. It delivers 4.7 mF capacitance at a 35 V rating in a smaller-sized snap-in package intended for tone-quality upgrades over smaller standard parts.

Key electrical and reliability attributes include ±20% capacitance tolerance, an operating temperature range of -40°C to +85°C, ripple-current capability specified at 2.1 A (120 Hz), and a rated life of 1000 hours at 85°C. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 μF) nominal capacitance with a 35 V rated voltage, specified for polarized applications.
• Snap‑in Radial Can Package — Snap‑in terminal mounting for secure chassis or PCB installation in a compact can (size: L: 3.5 × D: 2 cm).
• Audio‑oriented Design — Part of the LKS series described as “for audio equipment, smaller‑sized” and noted for tone‑quality improvement when used as a replacement for small standard products.
• Ripple Current — Rated ripple current of 2.1 A at 120 Hz, enabling effective smoothing in power and audio supply circuits where higher AC stress occurs.
• Temperature & Lifetime — Operating range -40°C to +85°C with an endurance rating of 1000 hours at 85°C; designed to meet specified endurance characteristics after the rated test.
• Leakage Current Specification — Leakage current after 5 minutes at 20°C is specified as not more than 3√(C·V) μA (C in μF, V in V), providing a verifiable limit for design calculations.
• Capacitance Tolerance & Loss — Capacitance tolerance ±20% at 120 Hz, 20°C; tangent of loss angle (tan δ) measured at 120 Hz per datasheet test conditions.
• Regulatory — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Used in amplifier and audio power-supply paths where replacing smaller standard capacitors can yield audible tone‑quality improvements.
• General‑Purpose Power Filtering — Bulk smoothing and decoupling in power supplies and regulator outputs within the specified voltage and temperature ranges.
• Electronic Upgrades and Replacements — Compact snap‑in form factor suited for retrofit or upgrade jobs where designers seek improved capacitance without large changes to mechanical layout.

Unique Advantages

• Audio‑focused specification — Marketed for audio equipment and noted for tone‑quality improvement when used to replace smaller standard parts.
• High ripple handling for its size — 2.1 A ripple current rating at 120 Hz supports robust smoothing in compact power designs.
• Compact snap‑in package — Radial snap‑in can enables secure mounting while keeping board and chassis footprint small (L: 3.5 × D: 2 cm).
• Defined leakage performance — Leakage limited to 3√(C·V) μA after 5 minutes at 20°C, allowing predictable loss budgeting in designs.
• Tested endurance — Endurance characterized to 1000 hours at 85°C with specified limits on capacitance change, tan δ, and leakage after the test.
• RoHS compliance — Conforms to current RoHS directives for use in regulated assemblies.
