Recommended Value
6.2 Ω ± 5%, 0.5 Watt, for 2.7 ≤ V
CC
≤ 3.6 V operation
15.0 Ω ± 5%, 0.5 Watt, for 4.75 ≤ V
CC
≤ 5.25 V operation
0.47 µF ± 20%, X7R Ceramic
6.8 µF ± 20%, Tantalum
Notes:
4. CX1 must be placed within 0.7 cm of the HSDL-3612 to obtain optimum noise immunity.
5. In “HSDL-3612 Functional Block Diagram” on page 1 it is assumed that Vled and V
CC
share the same supply voltage and filter capacitors. In case
the 2 pins are powered by different supplies CX2 is applicable for Vled and CX1 for V
CC
. In environments with noisy power supplies, including
CX2 on the V
CC
line can enhance supply rejection performance.

Marking Information
The HSDL-3612-007/-037 is marked “3612YYWW” on
the shield where “YY” indicates the unit’s manufactur-
ing year, and “WW” refers to the work week in which the
unit is tested.
CAUTIONS: The BiCMOS inherent to the design of this component increases the component’s susceptibility to dam-
age from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.
