ML514PYA Series
High-Reliability Power Inductors
ML514PYA Series offers high current and very low DCR.
- High temperature materials allow operation in ambient temperatures up to 155°C.
- Passes vibration testing to 80 G and shock testing to 1000 G.
- Soft saturation makes them ideal for VRM/VRD applications.
- Tin-silver (96.5/3.5) over copper terminations.

Notes
- When ordering, please specify screening code: e.g. ML514PYA822MLZ.
- Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A.
- DCR measured using a micro-ohmmeter.
- SRF measured using an Agilent/HP 4395A or equivalent.
- DC current at 25°C that causes an inductance drop of 30% (typ) 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.
Note:
Irms testing was performed on a 0.060” inch thick pcb with 4 oz copper traces optimized to minimize additional termperature 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.
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.
