The following are precautions for individual products. Please also refer to the common precautions shown on page 4
of this catalog.
1. Take measures against mechanical stress during and after mounting of Chip RC Networks (hereafter called the RC networks)
2. Do not use halogen-based or other high-activity fl ux. Otherwise, the residue may impair the RC networks' performance
3. Perform suffi cient preheating so that the difference of the solder temperature and the RC networks chip surface
4. When soldering with a soldering iron, never touch the RC networks' bodies with the tip of the soldering iron. When
5. As the amount of applied solder becomes larger, the mechanical stress applied to the RC networks increases, causing
6. Do not apply shock to the RC networks or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, the RC networks'
7. Avoid excessive bending of printed circuit boards in order to protect the RC networks from abnormal stress.
8. The static capacitance may decrease by a few percent from the time of shipment due to the characteristics peculiar to
Design and specifi cations are each subject to change without notice. Ask factory for the current technical specifi cations before purchase and/or use.

We do not recommend fl ow soldering to the prod uct, because solder bridging may occur due to the
narrow pitch of the terminals and the characteristics of the product may be badly affected when using
adhesive to affi x it to a circuit board.
