SMD Device

Applications

• Next generation microprocessors

• High current DC-DC converters

• Computers

Environmental Data

• Storage temperature range: -40°C to +125°C

• Operating temperature range: -40°C to +125°C (range is

application specific).

• Solder reflow temperature: +260°C maximum for 10

seconds maximum.

Packaging

• Units supplied in tape and reel packaging, 250 parts on

13” diameter reel.

1) OCL (Open Circuit Inductance) Test parameters: 300kHz, .25Vrms, 0.0Adc & Isat.

2) Irms Amps for approximately ΔT of 40°C. DC current for an approximate ΔT of 40°C without core

loss. Derating is necessary for AC currents. It is recommended that the temperature of the part

not exceed 125°C under worst case operating conditions verified in the end application.

3) Isat Amps Peak for approximately 30% rolloff @ 20°C

4) Applied Volt-Time product (V-

μS) across the inductor. This value represents the applied V-μS at

200kHz necessary to generate a core loss equal to 10% of the total losses for 40°C temperature

rise. See Core Loss Graph.

5) Part number definition - HC1-xxx-R:

• HC1 = Product code and size

• -xxx = Inductance value

• R = Decimal point (if no “R” is present,

third character = number of zeros)

• -R Suffix = RoHS compliant

Dimensions - mm
