Note) *1: Measured without HOE.
*2: Relation between PO and Topr is defined in figure 2. Absolute maximum ratings of the PO under the pulse operation (pulse width = 0.5 s, duty 50%, without bias current) is PO = 110 mW, Topr =60°C.
*3: Operating ambient temperature is defined under the condition of Rth 150°C/W. (Rth: Thermal resistence of the LDHU which is set into the pickup)
