LKS1H182MESY

The LKS1H182MESY is a snap-in, radial aluminum electrolytic capacitor designed for audio equipment and general-purpose electronic designs. It delivers 1.8 mF capacitance at a 50 V rating in a compact, smaller-sized snap-in can package intended as an upgrade or replacement for small standard products.

Key engineered characteristics include a polarized design, a wide operating temperature range, measurable ripple handling at low frequency, and a defined endurance life—features suited to power filtering and energy storage needs in assemblies where board-mount snap-in packaging is preferred.

Key Features

• Capacitance & Voltage: 1.8 mF nominal capacitance with a 50 V rated voltage, suitable for mid-voltage DC applications requiring bulk capacitance.
• Tolerance: ±20% capacitance tolerance (specified at 120 Hz, 20°C), enabling predictable sizing in designs specifying ±20% components.
• Package & Mounting: Radial, snap-in can package for secure board mounting and straightforward mechanical retention in assemblies.
• Polarized Design: Polar capacitor construction for DC power rails and filtering where polarity is observed.
• Temperature Range: Rated for operation from −40°C to +85°C, allowing use across common commercial and industrial ambient conditions.
• Endurance & Reliability: Specified lifetime of 1000 hours at 85°C under rated voltage, with post-endurance limits for capacitance change, loss tangent, and leakage current per datasheet endurance conditions.
• Low-frequency Ripple Handling: Rated ripple current of 1.6 A at 120 Hz, suitable for low-frequency smoothing applications in power circuitry.
• RoHS Compliant: Meets RoHS directive requirements (2011/65/EU,(EU)2015/863) for restricted substances.
• Compact Footprint: Physical size approximately L: 2.5 × D: 2.0 cm for space-conscious designs needing higher capacitance in a smaller can.

Typical Applications

• Audio Equipment — Designed for audio applications and noted for potential tone-quality improvement when used as a replacement for small standard capacitors.
• General-purpose Electronics — Provides bulk capacitance and DC filtering in general-purpose circuits where a polarized aluminum electrolytic is appropriate.
• Power Supply Filtering — Suitable for smoothing and low-frequency ripple attenuation in power rails within its rated voltage and ripple limits.

Unique Advantages

• Audio-focused replacement option: Marketed for audio equipment and can improve tone characteristics when replacing smaller standard parts, offering a simple upgrade path in audio designs.
• High bulk capacitance in a compact can: 1.8 mF in a smaller-sized snap-in package helps increase capacitance density without a large footprint.
• Defined ripple capability: 1.6 A ripple current at 120 Hz provides a quantifiable specification for low-frequency smoothing requirements.
• Durability under rated stress: 1000 hours endurance at 85°C under rated voltage gives designers measurable lifetime data for thermal and electrical stress planning.
• Wide operating temperature: −40°C to +85°C operation supports deployment across common ambient conditions.
• RoHS compliance: Meets current RoHS directive requirements for restricted substances.
