- High thermal stability with extended operating temperature range
- Through-hole TO-92-3 packaging for reliable mounting
Applications
- Low-noise amplifier circuits
- Analog switching applications
- Constant current source designs
Procurement Notes
Verify the specific suffix 'APM' against official datasheets to confirm tin/lead plating availability and RoHS exemption status. Ensure the ordering code matches the required bulk or ammo pack configuration. Confirm lead forming options if standard leads are unsuitable for the target assembly process. Cross-reference the manufacturer's latest documentation for any changes in material composition or testing standards.
Selection Notes
Select this component when an N-channel JFET with moderate current handling and low on-resistance is required. The TO-92-3 package suits through-hole prototyping and high-reliability environments. Consider the 40V voltage rating and 625mW power dissipation limits during circuit design. Verify compatibility with existing PCB footprints and thermal management requirements before finalizing the part choice.
