Coilcraft MS433PYA221MSZ High reliability power inductor Datasheet

4020 POWER INDUCTORS
High Reliability Power Inductors MS433PYA
■ High temperature materials allow operation in ambient
temperatures up to 155°C
■ Tin-lead (Sn-Pb) termination for the best possible board
adhesion
■ Exceptionally low DCR – 5.81 mOhm
■ Soft saturation makes them ideal for VRM/VRD applications.
Terminations Tin-lead (63/37) over copper.

1. When ordering, please specify testing code:
MS433PYA222MSZ
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, 0 Adc.
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.

Irms Testing
Irms testing was performed on 0.75 inch
wide × 0.25 inch thick copper traces in
still air.
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.
