1. OCL (Open Circuit Inductance)
2. Test parameters: 1MHz, 0.1Vrms, 0.0Adc. @25°C
3. The rated current and rated inductance per phase is determined by Volterra’s testing and circuit design. Additional
information can be provided by contacting Volterra.
5. This device is licensed for use only when incorporated within a voltage regulator employing power regulating
devices manufactured by Volterra Semiconductor, LLC or Maxim Integrated Devices, Inc. No license is granted
expressly or by implication to use this device with power regulating devices manufactured by any company other
than Volterra or Maxim.
4. Part Number Definition: CPLx-y-50TR-R-50TR-R
• CPLx= Product code and size - CPL (standard)/CPLA (acoustic dampening)/CPLE (low core loss)
• -y= number of phases • -50 = rated inductance value per phase in nH
• TR= Tape and reel
• -R suffix= RoHS compliant
