PCB Mounting
Solder lug terminals are spaced
.100” x .200” (2.54mm x 5.08mm).
This enables PCB mounting which can be
accomplished by elongating PC board
holes to .080” (2.03mm).

LED COLORS & SPECIFICATIONS
Series HB
The electrical specifications shown are determined at a basic temperature of 25°C.
LED circuit is isolated and requires external power source. Single element LED is colored in OFF state.
If the source voltage exceeds the rated voltage, a ballast resistor is required.
The resistor value can be calculated by using the formula in the Supplement section.
