www.eaton.com/electronics

Part marking: xxx= inductance value in μH, R= decimal point, If no R is present then last character equals number of zeros

yyyy= lot code

All soldering surfaces to be coplanar within 0.1 millimeters

Tolerances are ±0.3 millimeters unless stated otherwise

Pad layout tolerances are ±0.1 millimeters unless stated otherwise

DCR is measured from point “a” to point “b”

Traces or vias underneath the inductor is not recommended

1. Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.25 V

2. Full Load Inductance (FLL) Test Parameters: 100 kHz, 0.25 V

PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the

temperature rise. It is recommended that the temperature of the part not exceed +155 °C under worst case operating

conditions verified in the end application.

5. Short circuit inductance (SCL) test parametrs: 100 kHzs, 0.25 Vrms, 0.0 Adc, pins: (1 - 3) short pins (2 - 4)

L: (Inductance in μH), ΔI (Peak to peak ripple current in Amps).

7. Part Number Definition: HCSA1V1008-xxx-R

HCSA1V1008 = Product code and size

xxx= inductance value in μH, R= decimal point,

If no R is present then last character equals number of zeros
