7070 POWER INDUCTORS High-Reliability Power Inductors MS541PYA ■ High temperature materials allow operation in ambient temperatures up to 155°C ■ Passes vibration testing to 80 G and shock testing to 1000 G ■ Tin-lead (Sn-Pb) termination for the best possible board adhesion ■ High current and very low DCR ■ Soft saturation makes them ideal for VRM/VRD applications. Core material Composite Terminations Tin-lead (63/37) over copper. Weight 1.9 – 2.1g Ambient temperature –55°C to +105°C with Irms current, +105°C to +155°C with derated current Storage temperature Component: –55°C to +155°C.

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. 1. When ordering, please specify testing code: MS541PYA682MSZ 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 using an Agilent/HP 4192A. 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.
