[Data] Shirutoku Report No. 60 # Evaluation and Testing Items for Switching Power Supplies

Our company offers custom measurement services, proposing the construction of testing environments tailored to our customers' needs. We cater not only to general evaluations such as semiconductors but also to a wide range of specialized measurements, including high-sensitivity measurements, large currents, and high voltages. This time, we would like to introduce a transistor sorting inspection system that was developed in response to such requests. It is especially recommended for customers who are struggling with the desire to conduct evaluations that require custom solutions but cannot make capital investments. For more details, please refer to the related products and catalogs below.

Recently, with the spread of mobile devices, there has been remarkable progress in the miniaturization and high-capacity of ceramic capacitors. However, when using ceramic capacitors, it is essential to have a good understanding of their characteristics. In particular, those with high dielectric constants can have significant changes in capacitance due to temperature and applied voltage, so caution is necessary. This time, we will focus on the often-overlooked factor of "shock" and introduce important points to consider when using ceramic capacitors. For more details, please refer to the related products and catalogs below.

At WTI, we conduct design and development tailored to our customers' needs, but this time I will talk about principle verification. Here, principle verification refers to the confirmation of basic operations and characteristics before starting full-scale product design. When there is a request for new development and it is believed that there may be technical challenges, we may suggest starting with principle verification. For more details, please refer to the related products and catalogs below.

At WTI, we offer thermal design services that include predicting component temperatures and proposing heat dissipation measures, among which ventilation is one of the effective strategies. In today's life, the importance of ventilation in offices and rooms is increasing, and the fundamental concept of ventilation for electronic devices is the same as that for room ventilation. Therefore, this time we will introduce methods to ensure the entry and exit points for airflow during ventilation. For more details, please refer to the related products and catalogs below.
