- Wide operating temperature range
Applications
- Low-noise amplifier circuits
- High-impedance switching applications
- Analog signal modulation
Procurement Notes
Verify the specific suffix 'APM' against official datasheets to confirm packaging details, as standard listings may vary. Ensure RoHS compliance documentation matches the 'PBFREE' designation. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability status and lead times before finalizing procurement plans.
Selection Notes
Select this component for designs requiring high input impedance and low noise characteristics. Verify that the 40V voltage rating meets circuit requirements. Consider the TO-92-3 package constraints for thermal management and board space. Compare Idss and VGS(off) specifications against application needs to ensure proper biasing and performance.
Part Context
This part belongs to the Central Semiconductor JFET family, specifically designed for general-purpose analog applications. It complements other discrete semiconductor offerings from the manufacturer, providing reliable performance in small-signal environments. The TO-92-3 package is common for through-hole mounting in various electronic assemblies.
Replacement Considerations
Consult official substitution guides for equivalent N-channel JFETs with matching 40V ratings and TO-92 packages. Verify pinout compatibility and electrical parameter overlaps before replacing.
