SMPS Capacitors
RH Style - 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.
FEATURES
• RH 21/22 are AEC-Q200 compliant.
• RH range has low ESR/ESL capability
• PCB space saving using double stacked MLCCs
• Enhanced thermo mechanical stress resistance
Note: AVX does not recommend or advise the use of adhesives to secure the RH components to the PCB.
