Overview of LKG1E392MESYAK – Snap-In Aluminum Electrolytic Capacitor, 3.9 mF, 25 V
The LKG1E392MESYAK is a snap-in aluminum electrolytic capacitor from Nichicon's LKG series, engineered for audio applications. It provides 3,900 µF capacitance at a 25 V rating in a compact φ20 × 25 mm snap-in can.
Key attributes include a 1.6 A low-frequency ripple current rating (120 Hz), low leakage current (930 µA), a dissipation factor (tan δ) of 0.3 at 20°C/120 Hz, and an operating range of −40°C to 85°C with 1,000 hours endurance at 85°C. Status: End Of Life.
Key Features
- Capacitance & Tolerance — 3,900 µF (3.9 mF) with ±20% tolerance at 120 Hz, 20°C, suitable for bulk energy storage and smoothing tasks.
- Rated Voltage — 25 V rating for moderate-voltage audio power rails and filter stages.
- Low-Frequency Ripple Handling — Rated low-frequency ripple current of 1.6 A at 120 Hz, supporting power-supply ripple management in audio circuits.
- Low Leakage & Loss — Specified leakage current of 930 µA and tan δ of 0.3 (20°C, 120 Hz) for predictable bias behavior and dissipation.
- Endurance & Temperature Range — Specified lifetime of 1,000 hours at 85°C; operating temperature range −40°C to 85°C.
- Package & Mounting — Snap-in radial can (φ20 × 25 mm) in tray packing for straightforward chassis or PCB assembly.
- RoHS Compliance — Meets RoHS requirements as specified in the product data.
Typical Applications
- Professional audio power supplies — Bulk smoothing and reservoir capacitance for amplifiers and preamplifiers.
- High-fidelity audio systems — Decoupling and energy storage to support dynamic audio transients in high-grade equipment.
- Audio equipment assemblies — Power-filter networks and sub-assembly designs that require a compact snap-in capacitor with defined ripple and leakage.
Unique Advantages
- Engineered for audio use: Part of the LKG series designed specifically for high-grade audio equipment, prioritizing sound-quality-related characteristics.
- High ripple capability: 1.6 A low-frequency ripple rating at 120 Hz supports robust power-rail smoothing for audio power stages.
- Predictable electrical behavior: Specified leakage current (930 µA) and tan δ (0.3) provide stable, verifiable performance parameters for design calculations.
- Compact snap-in form factor: φ20 × 25 mm radial can with snap-in mounting enables space-efficient installation in chassis and assemblies.
- Rated endurance at elevated temperature: 1,000 hours at 85°C documents expected stability under sustained elevated-temperature operation.
- RoHS compliant: Meets regulatory requirements for restricted substances as noted in the product data.
