LKS1V183MESC

The LKS1V183MESC is an aluminum electrolytic capacitor in Nichicon’s LKS series featuring a snap-in terminal design for secure chassis mounting. Engineered for audio equipment and general-purpose electronic use, this smaller-sized component is offered as a replacement option intended to improve tone quality when substituted for smaller standard capacitors. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 18 mF rated capacitance at 35 V with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Polarized, Snap-in Package — Polarized radial can with snap-in terminals for robust mechanical retention in chassis or PCB assemblies.
• Size — Compact form factor with dimensions L: 3.5 × D: 3.5 cm suitable for space-constrained audio equipment.
• Operating Temperature & Lifetime — Rated for operation from −40°C to +85°C and specified for 1000 hours at 85°C with applied rated voltage.
• Ripple Handling — Rated ripple current of 4.05 A at 120 Hz, supporting smoothing and decoupling tasks in power circuits.
• Leakage & Endurance — Leakage current after 5 minutes at 20°C is not more than 3√CV (μA); after endurance testing (1000 h at 85°C with rated voltage) capacitance change remains within ±20% and leakage current does not exceed initial specified value.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Marking — Printed with silver-colored lettering on a black sleeve for clear identification.

Typical Applications

• Audio Equipment — Suited for use in audio circuits where replacement of smaller standard capacitors can contribute to tone-quality adjustments.
• General-Purpose Electronics — Applicable where high capacitance and snap-in mounting are needed for bulk energy storage and filtering.
• Upgrades & Replacements — Intended as a smaller-sized replacement option to upgrade existing capacitor implementations in assemblies.

Unique Advantages

• High Capacitance at Moderate Voltage: 18 mF at 35 V provides significant charge storage for smoothing and decoupling in power circuits.
• Audio-Focused Design: LKS series positioning for audio equipment and the explicit note on tone-quality improvement make this part suitable for audio upgrades and designs.
• Secure Snap-in Mounting: Snap-in terminals deliver stable mechanical retention for chassis- or board-mounted installations.
• Temperature and Endurance Specs: Rated for −40°C to +85°C with 1000 hours endurance at 85°C under rated voltage, offering predictable behavior over specified lifetime conditions.
• Measurable Ripple Capability: 4.05 A ripple current rating at 120 Hz supports reliable AC ripple handling in power supplies and amplifiers.
• RoHS Compliance: Conforms to RoHS directives (2011/65/EU, (EU)2015/863) for environmental regulatory requirements.
