Castellated design to ensure solder meniscus between board and component is visible
Thermal vias incorporated in design to enhance thermal performance
European manufactured (ITAR-free)
Rectangular design to aid in PCB assembly
Designed to be a more cost effective solution than our competition
Many standard types in stock and custom devices available on short lead time
Features:
Fully hermetic, ceramic diode leadless chip carrier
Replacement for MELF-style standard product with enhanced features
Optional deep dielectric discharge protection available
Optional international aerospace and space screening flows
