CL0904

Multi-Phase power inductors

www.eaton.com/electronics

Dimensions- mm

1. Open Circuit Inductance (OCL)

2. Test Parameters: 1MHz, 0.1Vrms, 0.0Adc.

3. The rated current, Imax peak 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: CL0904-x-50TR-R

- CL0904= Product code and size

- “x” = number of phases

- ”50” = inductance value per phase nH

- “TR” = Tape and Reel packaging

- “-R” suffix = RoHS compliant

A This device is licensed for use only when incorporated within a voltage regulator employing power

regulating devices manufactured by Maxim Integrated Devices. No license is granted expressly or

by implication to use this device with power regulating devices manufactured by any company

other than Maxim.
