LKS2A102MESB

The LKS2A102MESB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LKS series, specified at 1 mF (1000 μF) and 100 V. It is designed for general‑purpose use with a focus on audio equipment, where the series is noted for improved tone quality when replacing smaller standard capacitors.

Key electrical and reliability attributes include a ±20% capacitance tolerance, polarized construction, rated ripple current at 120 Hz, wide operating temperature range, and an endurance rating validated by a 1000‑hour test at 85°C.

Key Features

• Capacitance & Voltage — 1 mF nominal capacitance rated at 100 V for energy storage and smoothing in power rails and signal‑related circuits.
• Polarized Design — Electrolytic (polar) construction appropriate for DC smoothing and bulk filtering applications.
• Tolerance & Frequency Reference — ±20% capacitance tolerance specified at 120 Hz, 20°C to aid predictable filtering behavior.
• Ripple Handling — Rated ripple current of 1.95 A at 120 Hz to support moderate AC ripple environments in power supplies and amplifier circuits.
• Temperature & Endurance — Operating range −40°C to +85°C with an endurance specification of 1000 hours at 85°C under rated voltage.
• Mounting & Package — Snap‑in terminal, radial can (snap‑in) package for secure board attachment and mechanical stability.
• Leakage Current Specification — Leakage current defined by the datasheet formula: not more than 3√(C·V) μA after 5 minutes at 20°C, where C is μF and V is rated voltage.
• RoHS Compliant & Marking — Complies with RoHS (2011/65/EU, (EU)2015/863); sleeve marked with silver letters on black for clear polarity and part identification.

Typical Applications

• Audio Equipment — Used in audio circuits where replacing smaller standard capacitors can contribute to tone quality improvements and stable power delivery to amplifiers.
• General Purpose Power Filtering — Bulk filtering and smoothing on DC power rails in consumer and industrial electronic equipment.
• Power Supply Decoupling — Provides energy storage and ripple attenuation for moderate ripple current environments at 120 Hz.

Unique Advantages

• Designed for audio performance: LKS series positioning emphasizes tone‑quality improvement when upgrading from smaller standard capacitors.
• High working voltage: 100 V rating expands suitability to higher‑voltage power rails compared with lower‑voltage electrolytics.
• Measured ripple capability: 1.95 A @ 120 Hz gives a quantifiable basis for selecting this capacitor for moderate ripple environments.
• Validated endurance: 1000 hours at 85°C under rated voltage demonstrates defined performance over time at elevated temperature.
• Secure snap‑in mounting: Snap‑in terminals provide robust mechanical retention for board assembly and serviceability.
• Regulatory conformity: RoHS compliance supports environmentally conscious designs and procurement requirements.
