Procurement Notes
Verify the specific manufacturer datasheet for the LS840 SOIC 8L ROHS to confirm electrical characteristics and pinout compatibility. Ensure that the RoHS compliance status matches project requirements. Cross-reference the 8-SOIC package dimensions against PCB footprint specifications to guarantee accurate assembly and thermal performance during procurement.
Selection Notes
Select this component when a dual N-channel JFET is required in a surface mount format. Consider the 60 V Drain-Source Voltage limit and 0.5 mA current rating for suitability in low-power analog designs. Evaluate the 400 mW power dissipation capability relative to the expected thermal load in the target application environment.
