Caution
Mounting Direction: Mount products in the right direction. Wrong direction (90 rotated) can cause open/short circuits, flames, or other serious trouble.
Limitation of Applications: Contact Murata before using for applications requiring especially high reliability to prevent defects that might directly cause damage to third party's life, body, or property. This includes aircraft, aerospace, undersea, power plant control, medical, transportation, traffic signal, disaster/crime prevention, data-processing equipment, and applications of similar complexity and/or reliability requirements.
Notice
Products can only be soldered with reflow. This product is designed for solder mounting. Please consult us in advance for applying other mounting methods such as conductive adhesive.
