• Snap‑in Radial Can Package — Snap‑in mounting provides a robust mechanical connection for vertical PCB installation and easy assembly in power modules and chassis.
• Audio‑focused Design — LKS series is specified for audio equipment and is intended to deliver an effect to tone quality improvement when replacing smaller standard products.
• Tolerance & Polarization — ±20% capacitance tolerance at 120 Hz, 20 °C; polarized construction for DC power applications.
• Operating Temperature & Lifetime — Rated for operation from −40 °C to +85 °C with an endurance of 1000 hours at 85 °C under rated voltage.
• Ripple Handling & Loss — Rated low‑frequency ripple current of 4.7 A at 120 Hz; tangent of loss angle (tan δ) specified per LKS series measurement conditions.
• Leakage Current Specification — Leakage current meets the LKS series criterion of not more than 3√CV (μA) after 5 minutes application of rated voltage at 20 °C.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Dimensions — Package dimensions approximately L: 5 × D: 3.5 cm for space‑constrained power designs.

Typical Applications

• Audio Power Amplifiers — Bulk filtering and supply decoupling to support amplifier rails and help achieve consistent tonal characteristics.
• Power Supply Smoothing — Energy storage and ripple reduction on higher‑voltage DC rails in bench and consumer audio equipment.
• General‑Purpose Industrial Electronics — DC link and bulk capacitance where a polarized, high‑capacitance snap‑in solution is required.
