Key Features

• Capacitance & Voltage — 270 µF nominal capacitance rated for 400 V, suitable for high‑voltage bulk energy storage and filtering.
• Package & Mounting — Snap‑in radial can (φ30 × 35 mm / L: 3.5 cm × D: 3.0 cm) designed for secure PCB mounting; radial, can‑snap‑in package simplifies assembly.
• Operating Temperature & Lifetime — Specified operating temperature range of −25°C to +105°C with an endurance rating of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current — Rated ripple performance provided for multiple frequencies: 1.22 A at 120 Hz and 1.745 A at 100 kHz, supporting both low- and high-frequency ripple conditions.
• Acoustic & Audio Optimization — Part of the LKX 105°C series described as selected materials to achieve superior acoustic sound, intended for audio equipment and switching power supplies.
• Polarized with Tolerance — Polarized capacitor with capacitance tolerance of −20% to +20% (±20% standard at 120 Hz, 20°C).
• Regulatory — RoHS compliant.
• Identification — Marked with gold color letters on a black sleeve for clear identification.

Typical Applications

• Audio Equipment — Bulk filtering and decoupling in audio power stages where material selection and 105°C rating support sound‑quality focused designs.
• Switching Power Supplies — Energy storage and smoothing for high‑voltage sections of switching supplies, using the 400 V rating and high ripple handling.
• General Purpose Power Filtering — High‑voltage bulk capacitance for industrial and electronic systems requiring polarized electrolytic capacitors in a snap‑in form factor.

Unique Advantages

• High‑voltage capability — 400 V rating enables use in higher-voltage rails and minimizes the need for parallel components to achieve required voltage margins.
• Audio‑focused material selection — Part of a series specified for high‑quality sound, supporting designers focused on acoustic performance in audio equipment.
• Robust thermal endurance — 2000 hours at 105°C under rated conditions provides a clear, manufacturer‑specified expectation for long‑term performance in elevated temperatures.
• Snap‑in mounting for secure assembly — Radial snap‑in can package allows reliable retention on PCBs and efficient installation in production environments.
• Frequency-aware ripple ratings — Published ripple current values at 120 Hz and 100 kHz help designers size components for both mains‑frequency and high‑frequency switching noise.
• RoHS compliant — Meets RoHS requirements for regulatory conformity in lead‑restricted markets.
