Overview of LKG1K392MESCBK – Aluminum Electrolytic Capacitor, Snap‑In, 3.9 mF, 80 V
The LKG1K392MESCBK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series engineered for audio equipment. It provides 3900 µF capacitance at an 80 V rating in a radial snap‑in can, intended for use where audio‑grade power smoothing and high‑fidelity performance are required.
Key product attributes include a low loss tangent (tan δ = 0.25), a rated ripple current of 4.35 A at 120 Hz, polarized construction, and an operating range of −40 °C to +85 °C with 1000 hours endurance at 85 °C.
Key Features
- Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance, suitable for high‑voltage audio power applications.
- Audio‑focused design — Part of the LKG series designed for audio equipment and high‑fidelity sound, delivering characteristics targeted at audio power supply and coupling use cases.
- Low dissipation (tan δ) — Specified tan δ of 0.25 (measurement at 120 Hz, 20 °C) to help minimize dielectric loss in audio signal and power paths.
- High ripple handling — Rated ripple current of 4.35 A at 120 Hz for robust AC load performance in power supply filtering.
- Leakage current — Initial leakage current indicated as 1670 µA (measured in product specification), consistent with typical electrolytic capacitor behavior.
- Construction & mounting — Polarized aluminum electrolytic in a radial, snap‑in can package (φ35 × 45 mm body), providing secure board retention for vertical mounting.
- Temperature & lifetime — Operating range −40 °C to +85 °C with specified endurance of 1000 hours at 85 °C; shelf life and endurance characteristics defined per series specifications.
- RoHS compliant — Meets RoHS directive requirements as noted in the product series documentation.
Typical Applications
- High‑fidelity audio amplifiers — Bulk energy storage and smoothing in power rails for amplifiers where stable supply reduces audible distortion.
- Audio power supplies — Filtering and ripple reduction in linear and switch‑mode power supplies for audio equipment.
- Professional A/V equipment — Power decoupling and reservoir capacitance in receivers, preamps, and other high‑grade audio electronics.
Unique Advantages
- Audio‑oriented engineering: Designed under the LKG series for audio use, offering characteristics targeted to high‑fidelity sound systems.
- High voltage capability: 80 V rating provides greater headroom for higher‑voltage audio power rails and system designs.
- Strong ripple endurance: 4.35 A ripple rating at 120 Hz supports sustained AC stress in power supply applications.
- Reliable operating envelope: −40 °C to +85 °C range and 1000 hours endurance at 85 °C give predictable life performance under rated conditions.
- Secure snap‑in mounting: Radial snap‑in can package ensures firm mechanical retention for vertical board installations.
- Standards compliance: RoHS compliance aligns with contemporary regulatory and environmental requirements.
