LKG1C103MESBAK

The LKG1C103MESBAK is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKG series, specified for audio equipment. It delivers high bulk capacitance in a compact radial snap-in can and is designed with audio-grade characteristics intended to support high-fidelity audio applications.

Key electrical and mechanical attributes include 10,000 µF capacitance at 16 V, a rated temperature range of -40 °C to +85 °C, and a low-frequency ripple current rating of 2.1 A (120 Hz). Note: this part is listed as End Of Life/Discontinued.

Key Features

• Audio-focused design — Series-level design intent is for high-grade audio equipment and high-fidelity sound quality.
• High bulk capacitance — 10,000 µF (10 mF) capacitance provides substantial energy storage for audio systems that require large reservoir capacitance.
• Rated voltage — 16 V working voltage suitable for a range of low-voltage audio circuits.
• Loss factor (tan δ) — tanδ = 0.35 (measured at 20 °C, 120 Hz), specified for the part.
• Ripple handling — Low-frequency ripple current rating of 2.1 A at 120 Hz for sustained ripple performance.
• Leakage current — Specified leakage current 1200 µA at standard test conditions.
• Temperature and endurance — Operating range -40 °C to +85 °C with endurance specified as 1000 hours at 85 °C.
• Form factor and mounting — Radial, snap-in can package (φ30 × 20 mm), designed for snap-in board mounting; packaged in trays for handling.
• Compliance — RoHS compliant.
• Polarized — Standard polarized aluminum electrolytic construction for DC applications.

Typical Applications

• High‑grade audio equipment — Intended for use in audio systems where the series’ design priorities emphasize high-fidelity sound quality.
• HD Audio systems — Meets the series-level statement of addressing high tone quality needs for HD Audio equipment.
• Snap-in assemblies — Suitable where radial snap-in can packages are required and tray packing is preferred for assembly handling.

Unique Advantages

• Substantial energy storage: 10,000 µF capacitance supports large reservoir requirements in audio designs.
• Designed for audio fidelity: Series-level design emphasis on high-grade audio and high-fidelity sound quality aligns the part to audio-focused applications.
• Robust ripple capability: 2.1 A low-frequency ripple current rating at 120 Hz helps manage sustained ripple in audio power domains.
• Thermal endurance: Rated endurance of 1000 hours at 85 °C provides a defined reliability envelope for elevated-temperature operation.
• Compact, serviceable package: φ30 × 20 mm snap-in can offers a compact footprint with board-mounted snap-in convenience and tray packaging for assembly.
• Regulatory compliance: RoHS-compliant construction supports regulatory requirements for lead-free assemblies.
