Overview of LKG1C183MESBAK – Aluminum Electrolytic Capacitor, Snap-In, 18,000 µF, 16 V
The LKG1C183MESBAK is an aluminum electrolytic capacitor in a snap-in radial can package, engineered for audio equipment. It provides a high capacitance (18,000 µF) at a 16 V rating, making it suitable for bulk energy storage and smoothing in high‑grade audio power supplies and related circuits.
Designed within the LKG series for audio use, this part combines large capacitance, a snap‑in mounting style, and performance characteristics specified for demanding audio applications where fidelity and stable power delivery are priorities.
Key Features
- Capacitance & Voltage: 18,000 µF nominal capacitance at a 16 V rated voltage with ±20% tolerance, providing substantial bulk storage for power supply filtering.
- Mounting & Package: Snap‑in terminal, radial can (φ30 × 30L / approximately 3 cm × 3 cm), optimized for secure chassis or PCB-mounted power modules.
- Audio‑Focused Design: Part of the LKG series specified "For Audio Use" and described in the datasheet as designed for high‑grade audio equipment and high‑fidelity sound quality.
- Electrical Loss (tan δ): tan δ = 0.35 (measurement frequency: 120 Hz at 20°C), suitable for specifying ESR-related performance in audio power circuits.
- Ripple Current: Rated ripple current 2.65 A at 120 Hz, supporting continuous smoothing duties in power rails.
- Leakage Current Specification: After 5 minutes' application of rated voltage at 20°C, leakage current is specified as not more than 3√(C·V) µA (C in µF, V in V) per the series datasheet.
- Temperature & Reliability: Operating temperature range −40°C to +85°C with an endurance specification of 1000 hours at 85°C.
- Environmental Compliance: RoHS compliant as stated in the product information.
Typical Applications
- High‑Grade Audio Amplifiers: Bulk filtering and reservoir capacitance for power supplies to support consistent, low‑noise power delivery in premium audio amplifiers.
- Consumer Audio Equipment: Energy storage and smoothing in component audio systems and high‑fidelity consumer electronics where large capacitance is required.
- Audio Power Modules and Preamp Circuits: Supply decoupling and transient energy support to stabilize rails feeding sensitive analog stages.
Unique Advantages
- Large Bulk Capacitance: 18,000 µF provides substantial energy reserve to support low‑frequency power demands and reduce supply ripple.
- Audio‑Oriented Series Design: LKG series is specified for audio use, aligning component choice with designs prioritizing sound quality.
- Snap‑In Reliability: Snap‑in radial can construction facilitates robust mechanical retention for power assemblies and chassis installations.
- Defined Loss and Ripple Characteristics: Specified tan δ and ripple current allow straightforward integration into power‑supply designs with predictable thermal and electrical behavior.
- Operational Durability: Rated for −40°C to +85°C operation with a 1000‑hour endurance at 85°C, supporting long‑term stability in temperature‑challenging environments.
- RoHS Compliance: Meets RoHS requirements for environmental and regulatory consistency across product designs.
