LKSH2472MESB

The LKSH2472MESB is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKS series, offering 4.7 mF (4700 µF) capacitance at a 71 V rating in a compact φ30 × 35 mm can. Designed for smaller-sized audio and general-purpose electronic equipment, it delivers high bulk capacitance, full polarization, and snap‑in mounting for vertical assembly.

Key operating characteristics include a rated temperature range of -40 °C to 85 °C and an endurance rating of 1000 hours at 85 °C. Status: End Of Life.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance rated at 71 V, providing substantial bulk energy storage for designs requiring higher voltage handling.
• Capacitance Tolerance — Specified tolerance of -20% to +20% (±20% at 120 Hz, 20 °C) for predictable performance in design margins.
• Loss Tangent (tan δ) — tan δ = 0.3 measured at 20 °C, 120 Hz, enabling designers to account for dissipation in low‑frequency applications.
• Ripple Current Capability — Low frequency ripple current 3.4 A (at 120 Hz) to support ripple handling in bulk filtering roles.
• Leakage Current — Specified leakage current of 1730 µA after initial application of rated voltage (measurement condition per product data).
• Endurance & Temperature — Rated life 1000 hours at 85 °C; operating temperature range from -40 °C to 85 °C for broad environmental coverage.
• Package & Mounting — Radial, snap‑in can (φ30 × 35 mm) supplied in tray packing for assembly efficiency and secure vertical board mounting.
• Compliance — RoHS compliant per product data.

Typical Applications

• Audio Equipment — Suited for smaller-sized audio systems within the LKS series scope, where high-capacitance snap‑in components are required.
• General-Purpose Electronics — Used in general-purpose circuits that require bulk capacitance at elevated voltage ratings within the stated temperature and endurance limits.
• PCB Vertical Assembly — Snap‑in radial can format and tray packing facilitate vertical mounting applications and repeatable assembly processes.

Unique Advantages

• High Capacitance at Elevated Voltage: 4700 µF at 71 V provides significant bulk storage for designs that require both capacitance and higher voltage capability.
• Measured Dissipation Data: Specified tan δ (0.3 at 20 °C, 120 Hz) lets engineers quantify dielectric loss for low-frequency designs.
• Robust Ripple Handling: 3.4 A ripple current (120 Hz) supports applications with moderate low-frequency ripple demands.
• Durability in Elevated Temperature: Endurance of 1000 hours at 85 °C gives a defined lifecycle metric for thermal stress planning.
• Assembly-Friendly Package: Snap‑in radial can and tray packing simplify vertical PCB mounting and handling during production.
• Regulatory Compliance: RoHS compliance aligns the component with common environmental requirements.
