< Back DFN Sample Kit Overview Now it’s easier than ever to test-drive Linear Systems’ most popular parts in one of the industry’s smallest leadless packages. This kit includes a sampling of discretes in the near chip scale footprint, DFN 8L package. The DFN package is a plastic encapsulated package with a copper lead frame substrate. It offers a thin profile, low weight and good thermal and electrical performance. Electrical contact to the PCB is made by soldering perimeter leads to PCB. There is no die attach pad exposed on the bottom surface of the package, which provides more flexible PCB level circuitry routing and in some cases, more thermal resistance for the heat conduction from PCB to component. In this kit you will receive 3 pieces of each of the following parts: 174 DFN 8L RoHS: P-Channel, Single, JFET Switch 4392 DFN 8L RoHS: Low Noise, N-Channel JFET Switch PAD5 DFN 8L RoHS: Low Leakage, Single, Pico-Amp Diode 589 DFN 8L RoHS: Monolithic Dual, N-Channel JFET 489 DFN 8L RoHS: Low Noise, Low Capacitance, Monolithic Dual, N-Channel JFET 689 DFN 8L RoHS: Low Noise, Low Capacitance, Monolithic Dual, P-Channel JFET 352 DFN 8L RoHS: Tightly Matched, Monolithic Dual, PNP Transistor 312 DFN 8L RoHS: Tightly Matched, Monolithic Dual, NPN Transistor Ordering Information When ordering this kit please use the following part call out: DFN SAMPLE BOX
