Notes

When ordering, specify conductors and screening codes: e.g. ML515PMD101MLZ.
Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
DCR is measured on a micro-ohmmeter at points indicated in the diagram.
This information is for design purposes only and shall not be tested during screening.
DC current at 25±C that causes an inductance drops of 20% (typ) from its value without current.
Current that causes a 40°C rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Due to the design of this component, DWV and IR shall not be specified or tested.

Screening:

Z = Unscreened
Y = Unscreened (SLDC Option A)
W = Unscreened (SLDC Option B)
H = Coilcraft CP-SA-10001 Group A
G = Coilcraft CP-SA-10001 Group A (SLDC Option A)
D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
1 = EEE-INST-002 (Family 1) Level 1
2 = EEE-INST-002 (Family 1) Level 2
3 = EEE-INST-002 (Family 1) Level 3
4 = MIL-STD-981 (Family 04) Class B
5 = MIL-STD-981 (Family 04) Class S
F = ESCC3201 (F4 operational life performed at 105°C)
Screening performed to the document’s latest revision.

Notes:
1. Dimensions are in inches/mm.
2. Dimensions are before optional solder application. For maximum overall dimensions including solder, add 0.0025 in / 0.064 mm to the length, and 0.006 in / 0.15 mm to the height.
3. Top surface is divided by a slot which should be considered when handled by a vacuum pick-and-place process.
