SMPS Capacitors (RH Style)
RH - Surface Mount ‘J’ Lead Range
The RH range uses high volumetric efficient X7R capacitors in a “J” style lead frame.
The range of components are uncoated and are suitable for input or output filter capacitors in
high frequency DC-DC convertor, automotive, telecom, industrial and military applications.
When large ceramic capacitors are used in applications they can easily be affected by stresses
caused by temperature variations, thermal shock, mechanical vibrations and PCB bend
movement. The RH range is designed with a “J” type lead frame which greatly reduces all of
these thermo mechanical stresses experienced by large capacitors. The RH range allows the
capacitors to be doubled stacked so a higher volumetric efficiency can be achieved by the
customer and this saves PCB space.
