September, 2020 Knowles Introduces
Capacitor Assemblies for Power Supplies
ITASCA, IL — Knowles Precision Devices has released its SV series of capacitor assemblies for power sup- ply filtering applications. The SV series
contains vertically
stacked ceramic capacitors. They are designed to offer greater performance than alu- minum or tantalum electrolytic capacitors, while also helping to reduce the overall PCB foot- print.
The SV series is suited ide-
ally for the input and output stages of switch mode power supplies and DC-DC converters. SV series capacitor assemblies are available in the X7R dielectric with a high capacitance to volume ratio. Low equivalent series resist-
ance (ESR) and low equivalent series inductance (ESL) are inherent in the SV series design, which gives the assemblies the ability to handle high

Push-Pull M12
Connector with Inner Locking from Yamaichi
ASCHHEIM-DORNACH, GERMANY — Yamaichi Electronics has intro- duced its push-pull M12 connector with inner locking, which has been defined by the international standard IEC 61076-2-012. The cable-side connector
engages deep into the device socket from the inside with lock- ing hooks. The push-pull system requires only the same installa- tion space as a common M12 connection with screw locking. With this design, the M12
socket can be inserted complete- ly into the device, e.g. to inte- grate it into a distribution box, aligned flush with its housing. The system is IP65/67 water- and dust- proof and uses independent seals for screw-type or push-pull connectors. The long locking hooks of the
cable connector are supported by the threaded segments of the device socket. This makes the system extremely durable, especially when subjected to torsional loads and rota-
