Notes
- When ordering, specify conductors, termination and screening codes: e.g. ST515PMM101MLZ.
- 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 a 20% (typ) inductance drop from its value without current.
- Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
Termination:
- L = Matte tin over nickel over copper.
- T = Tin-silver-copper (95.5/4/0.5). (Special order, added cost)
- S = Tin-lead (63/37). (Special order, added cost)
Screening:
- Z = Unscreened
- Y = Unscreened (SLDC Option A)
- W = Unscreened (SLDC Option B)
- H = Group A screening per Coilcraft CP-SA-10001
- G= Coilcraft CP-SA-10001 Group A (SLDC Option A)
- D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
Custom screening also available.

Physical characteristics
Dimensions - Single Conductor
Dimensions - Dual Conductor
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.
