Packaging information (mm)

Supplied in tape and reel packaging, 200 parts per 13” diameter reel.

Dimensions (mm)

DCR measured from point “a” to point “b”

Part marking: Pin 1 dot, 17-18913-R, wwllyy = date code, R = revision level

Tolerances are ±0. 25 millimeters unless stated otherwise.

All soldering surfaces to be be coplanar within 0.13 millimeters.

Do not route traces or vias underneath the inductor

1. Open Circuit Inductance (OCL) Test parameters: 1MHz, 0.1Vrms, +25°C

2. Open Circuit Inductance (OCL) Test parameters: 1MHz, 0.1Vrms, +105°C

3. Isat1: Peak current at which OCL drops to 200nH min @ 25°C

Isat2: Peak current at which OCL drops to 200nH min @ 105°C

Isat3: Peak current at which SCL drops approximately 20% @ 105°C

4. Short Circuit Inductance (SCL) Test parameters: 1MHz, 0.1Vrms, 0.0Adc @25°C ±20% short pins 1 and 4,

measure pins 2 and 3 and divide by 2.
