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.

4. Part Number Definition: CPL2-x-50TR-R

• CPL2= Product code and size

• -x= number of phases

• -50 = rated inductance value per phase in nH

• TR= Tape and reel

• -R suffix= RoHS compliant

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.

Dimensions (mm)

Part marking: Pin 1 dot, CPL2= (product code and size),-2,-3,-4,-5, = (number of phases)

wwllyy = date code, R = revision level
