J-lead

J-lead

A pin on a chip package that extends down and around under the housing like a reverse "J." J-leads are used on SOJ chips. See SOJ and gull-wing lead.

Availability with gold-plated J-lead, tin/lead-plated J-lead, and gold-plated undertab terminations.
Basic J-lead tantalum capacitors have metal leads attached to the sides of the capacitor body and wrapped under the capacitor, which provides complete mechanical decoupling from the PCB, and enables extremely high vibration resistance.
In a conventional molded J-lead package, the anode wire is welded to one side of the J-lead, and the cathode side is glued to a lead frame pocket with a conductive epoxy.
Or I could bend the leads under to approximate a J-lead part.
X-ray inspection of a lifted J-lead (Figure 1) was part of an investigation to pinpoint the possible cause of open joints.
Due to the non-wetting (no-flow) characteristic of lead-free solder, J-Lead and Gull Wing component leads are not recommended.
Additionally, J-lead packaging technology is used to reduce footprint to .
Currently, the PVG3 series offers two terminal shapes: J-lead (PVG3A) and Gull Wing (PVG3G).
J-lead package options support on-board surface mounting with a profile as low as 0.
In a conventional molded, J-lead package (FIGURE 4), the anode riser wire is welded to one side of the J-lead, while the tantalum element, which features an external cathode coating, is affixed to a lead frame pocket with conductive epoxy.
Built on a glass-reinforced resin base, the device eliminates the problematic J-lead construction and associated current-loops, thereby reducing ESL by two thirds that of traditional capacitors.
Gullwing, J-lead, wrap-around and L-bend component lead forms have a toe, heel and side solder joint goal.
