This product may not be used in medical or high

risk applications without prior Coilcraft approval.

Specifications subject to change without notice.

Please check our web site for latest information.

1. When ordering, please specify

testing code:

Testing: Z = COTS

H = Screening per Coilcraft CP-SA-10001

N = Screening per Coilcraft CP-SA-10004

2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A.

3. DCR measured on a micro-ohmmeter.

4. SRF measured using an Agilent/HP 4395A or equivalent.

5. Typical dc current at which the inductance drops 30% from its value without current.

6. Typical current that causes the specified temperature rise from 25°C ambient.

7. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

■

High temperature materials allow operation in ambient

temperatures up to 155°C

■

Passes vibration testing to 80 G and shock testing to 1000 G

■

Tin-lead (Sn-Pb) termination for the best possible board

adhesion

■

High current and very low DCR

■

Soft saturation makes them ideal for VRM/VRD applications.

Irms Testing

Irms testing was performed on a

0.060

″ thick pcb with 4 oz. copper

traces optimized to minimize

additional temperature rise.

Temperature rise is highly

dependent on many factors

including pcb land pattern,

trace size, and proximity to

other components. Therefore

temperature rise should be

verified in application conditions.
