Vishay / BC Components 172 RLX Aluminum Electrolytic Capacitors are AEC-Q200 qualified capacitors with very low impedance, low ESR, and a very long useful life. These capacitors offer high stability, high reliability, and excellent ripple current capability. The 172 RLX capacitors have radial leads and a cylindrical aluminum case with pressure relief. These capacitors are charge and discharge proof and operate within -40°C to +105°C temperature range. Typical applications include smoothing, filtering, buffering, and power supplier for general industrial, EDP, audio-video, automotive, and telecommunications.
