4020 POWER INDUCTORS

Document MS806-1 Revised 01/18/12

Terminations Tin-lead (63/37) over copper.

Core material Composite

Weight 0.17 – 0.18 g

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.

Tape and reel packaging: –55°C to +80°C

Resistance to soldering heat Max three 40 second reflows at

+260°C, parts cooled to room temperature between cycles

Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /

85% relative humidity)

Enhanced crush-resistant packaging 1000/7

″reel; 3500/13″ reel

Plastic tape: 12 mm wide, 0.23 mm thick, 8 mm pocket spacing,

2.3 mm pocket depth

I

High temperature materials allow operation in ambient

temperatures up to 155°C

I

Tin-lead (Sn-Pb) termination for the best possible board

adhesion

I

Exceptionally low DCR – 5.81 mOhm

I

Soft saturation makes them ideal for VRM/VRD applications.

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 compo-

nents. Therefore temperature rise should

be verified in application conditions.
