LKS1H822MESB

The LKS1H822MESB is a snap‑in, polarized aluminum electrolytic capacitor from Nichicon's LKS series. It provides 8200 µF capacitance at a 50 V rating in a φ30 × 40 mm can (snap‑in radial) and is supplied in tray packing.

Engineered for smaller‑sized and audio‑focused applications, the LKS1H822MESB offers a balance of bulk energy storage, low‑frequency ripple handling and validated endurance for designs operating across −40 °C to +85 °C.

Key Features

• Capacitance & Tolerance — 8.2 mF (8200 µF) with a tolerance of −20% to +20% at 120 Hz, 20 °C.
• Voltage Rating — 50 V rated voltage suitable for mid‑voltage applications requiring polarized electrolytic capacitance.
• Snap‑In Radial Package — φ30 × 40 L can (radial, snap‑in) for secure PCB mounting and mechanical stability; supplied in tray packing for handling.
• Ripple Current Capability — Low‑frequency ripple current of 3.45 A (measured at 120 Hz), supporting higher AC stress at power rails and smoothing points.
• Loss Characteristics — tan δ (DF) of 0.30 measured at 20 °C, 120 Hz, for predictable dissipation behavior.
• Leakage Current — Specified leakage current of 1920 µA after rated voltage is applied (measurement condition: 20 °C).
• Temperature & Endurance — Operating range −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C.
• Regulatory — RoHS compliant.
• Product Status — End Of Life (legacy product status).

Typical Applications

• Audio equipment — Designed for smaller‑sized audio designs where the LKS series is specified to improve tone quality when replacing smaller standard capacitors.
• General‑purpose electronic equipment — Suited for applications that require polarized aluminum electrolytic capacitors for bulk energy storage and decoupling in general electronic assemblies.
• Power filtering and smoothing — Used where mid‑voltage bulk capacitance and specified ripple current handling are required at low frequencies (120 Hz).

Unique Advantages

• High bulk capacitance: 8200 µF provides substantial energy storage for smoothing and decoupling tasks, reducing the need for multiple smaller capacitors.
• Mid‑voltage capability: 50 V rating enables use in systems with higher rail voltages while maintaining compact cylindrical packaging.
• Robust ripple handling: 3.45 A low‑frequency ripple current rating at 120 Hz supports higher AC stress points in power circuits.
• Predictable dissipation: tan δ = 0.30 (20 °C, 120 Hz) offers consistent loss characteristics for thermal and reliability planning.
• Endurance validated: 1000 hours at 85 °C endurance rating provides a defined lifetime metric for thermal stress considerations.
• RoHS compliant: Meets RoHS requirements for regulatory compliance in applicable designs.
