What are the features of Murata’s lead type multilayer ceramic capacitors?This article summarizes the

Lead-type multilayer ceramic capacitors are products obtained by bonding wires to the electrodes of chip multilayer ceramic capacitors and coating them with resin. In addition to the small size, high capacitance, and long-term reliability of multilayer ceramic capacitors, various added values ​​can be provided through resin coating and lead wires.

“Easy to use” is the main feature of lead type multilayer ceramic capacitors

Lead-type multilayer ceramic capacitors are products obtained by bonding wires to the electrodes of chip multilayer ceramic capacitors and coating them with resin. In addition to the small size, high capacitance, and long-term reliability of multilayer ceramic capacitors, various added values ​​can be provided through resin coating and lead wires.

In the last issue, we introduced the five features of Murata’s lead-type multilayer ceramic capacitors, application examples, and Murata’s product specifications. Here, we will introduce you to Murata’s four series of lead-type multilayer ceramic capacitors in detail.

Product list
