LKS1E333MESC

The LKS1E333MESC is a snap-in, radial-can aluminum electrolytic capacitor from Nichicon's LKS series, optimized for audio equipment and general-purpose applications. It offers high capacitance (33 mF) at a 25 V rating in a compact snap-in package intended as a smaller-sized upgrade to standard products for improved tone quality.

Engineered for board-mounted assemblies, the LKS1E333MESC combines large capacitance, a 4.6 A (120 Hz) ripple current capability, and RoHS compliance for use in consumer and professional audio circuits and other general-purpose power filtering roles.

Key Features

• Capacitance & Voltage — 33 mF capacitance rated at 25 V provides substantial charge storage for filtering and decoupling in audio and general-purpose power circuits.
• Snap-in Package — Radial, can-type snap-in mounting simplifies PCB assembly and mechanical retention for power-supply and audio-board designs.
• Audio-focused Series — Part of the LKS series described as “Snap-in Terminal Type, For Audio Equipment, Smaller-sized” with a stated effect of tone-quality improvement when used as a replacement for smaller standard parts.
• Ripple Current — Rated ripple current of 4.6 A at 120 Hz supports sustained AC ripple handling in low-frequency power applications.
• Temperature Range — Operates across a category temperature range of −40 °C to +85 °C to cover typical ambient and enclosure conditions.
• Endurance — Rated lifetime of 1000 hours at 85 °C; endurance specifications require capacitance change within ±20%, tan δ ≤ 200% of initial spec, and leakage current ≤ initial specified value after the test.
• Leakage Current — After 5 minutes at rated voltage and 20 °C, leakage current is specified as not more than 3√(C·V) µA (C in µF, V in V), per the series datasheet.
• Tolerance & Loss — Capacitance tolerance ±20% (measured at 120 Hz, 20 °C); tangent of loss angle (tan δ) is measured at 120 Hz, 20 °C per datasheet guidance.
• Size — Compact footprint with nominal dimensions L: 4.5 × D: 3.5 cm for designs where board area and mounting stability are considerations.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized — Polarized aluminum electrolytic type; intended for DC-biased filtering and smoothing.

Typical Applications

• Audio Equipment — Bulk smoothing and reservoir capacitance in amplifiers and preamplifiers where higher capacitance and series-design tone improvement are desired.
• Power Filtering — General-purpose DC rail filtering and decoupling for consumer and professional electronics using snap-in board mounts for reliable mechanical and electrical connection.
• Component Upgrade / Replacement — Replacement for smaller standard capacitors to increase effective capacitance and influence tone characteristics in audio designs.

Unique Advantages

• Large Capacitance in a Snap-in Can — 33 mF at 25 V provides high charge reserve while retaining the mechanical convenience of snap-in mounting.
• Designed for Audio Use — Series-level description highlights tone-quality improvements when used as a replacement, making it an option for audio-focused designs seeking audible differences.
• Measured Electrical Limits — Explicit ripple current rating (4.6 A at 120 Hz) and leakage-current formula allow designers to size and validate power-handling and standby losses.
• High-Temperature Endurance — 1000-hour rating at 85 °C with defined post-test limits on capacitance, tan δ, and leakage supports predictable long-term behavior in warmed enclosures.
• Wide Operating Range — −40 °C to +85 °C category temperature range expands deployment across common consumer and professional environments.
• RoHS Compliant — Meets RoHS requirements for restricted substances, aligning with regulatory requirements for many markets.
