LKSH2222MESY

The LKSH2222MESY is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general-purpose electronic applications. It delivers 2.2 mF capacitance at a 71 V rating in a compact, smaller-sized snap-in can (φ22 × 40 mm) targeted where robust filtering and compact board mounting are required.

Engineered for practical performance, this polarized capacitor offers industry-relevant ripple handling and an endurance profile suitable for sustained operation at elevated ambient temperatures.

Key Features

• Capacitance & Voltage: 2.2 mF (2200 µF) rated at 71 V for bulk energy storage and decoupling in power circuits.
• Snap‑in Mounting / Package: Radial, can-style snap-in terminals simplify board installation and secure mechanical retention in chassis and PCBs.
• Compact Dimensions: φ22 × 40 mm (L) footprint provides a smaller-sized option within the LKS series for space-constrained audio and general-purpose designs.
• Endurance & Temperature Range: Rated for 1000 hours at 85 °C with an operating temperature range of −40 °C to +85 °C, supporting sustained operation at elevated temperatures.
• Ripple Current Capability: 2.25 A at 120 Hz, enabling effective smoothing of low-frequency ripple in power supply and amplifier stages.
• Electrical Characteristics: Capacitance tolerance ±20% (measured at 120 Hz, 20 °C); specified leakage current 1180 µA.
• RoHS Compliant & Packaging: RoHS-compliant construction and supplied in tray packing for handling and assembly.

Typical Applications

• Audio Equipment: Bulk smoothing and power reservoir for amplifier power rails where the LKS series’ smaller size and tonal-quality characteristics are desirable.
• Power Supply Filtering: Low-frequency ripple filtering and energy storage in general-purpose power supplies requiring a 71 V, 2200 µF capacitor.
• Chassis-mounted/Panel Installations: Snap-in mounting provides secure mechanical retention for assemblies that require robust board or chassis attachment.

Unique Advantages

• Compact, snap-in form factor: φ22 × 40 mm package with snap-in terminals reduces board footprint while providing strong mechanical retention.
• High-voltage capability: 71 V rating supports higher-voltage rails and gives designers headroom for power and audio amplifier topologies.
• Designed for audio use: LKS series positioning emphasizes smaller size and tonal-quality improvement for audio applications.
• Durability at elevated temperature: 1000-hour endurance at 85 °C offers predictable performance for sustained thermal conditions.
• Effective ripple handling: 2.25 A ripple rating at 120 Hz enables reliable low-frequency smoothing in power circuits.
• Regulatory compliance and handling: RoHS-compliant construction and tray packing streamline assembly and compliance processes.
