Vicor adds an 800V compatible model to the Ultra High Voltage Bus Converter Module "BCM4414".

Achieving high efficiency and high power density! It is possible to reduce the large-capacity capacitors required for the load.

The "BCM Series" is an isolated DC-DC converter with a fixed voltage conversion ratio, designed to be compact, lightweight, and highly efficient with high power density. It is a small, high-frequency DC-DC converter equipped with galvanic isolation, stepping down the input voltage at a fixed conversion ratio. It supports a wide range of output voltages and power levels, with various conversion ratios available. The peak efficiency reaches up to 98%, with a power density of up to 2,870W/in³, and temperature grades can be selected. Please feel free to contact us if you have any requests. 【Features】 ■ Supports high power with parallel connection ■ Outputs high voltage with series connection of outputs ■ Bidirectional voltage conversion ■ Superior in compactness and cost-effectiveness ■ Achieves very high efficiency and power density with low noise and fast transient response *For more details, please refer to the PDF materials or feel free to contact us.

Regarding the "quotation" used at the forefront of sales activities: "Do we really need to save everything when we revise it to Ver.1, Ver.2, etc., every time the amount or specifications change?" "Should we also keep the data from other companies that were not selected in competitive quotations?" Have you ever wondered about these questions? The Electronic Bookkeeping Act strictly demands the "authenticity" of data, but saving every process is a significant burden for the field. This time, we will clearly explain the boundaries of the preservation obligation in a case study format, incorporating the latest interpretations from the National Tax Agency's Q&A. *You can read the full text from the note in the "Related Links." [Contents of this article] 1. The boundary of the preservation obligation lies in "sending to external parties." - Items sent externally are "generally required to be preserved." - Items not sent externally have "no preservation obligation." 2. The sender's judgment: "Is it linked to a transaction?" 3. The recipient's judgment: "The perspective of the 'Corporate Tax Act' is important." ■ Note! "Version revisions" and "corrections/deletions" are different things. ■ A smart way to achieve reliable "version management." ■ Summary

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

What is a sealed product air leak test device? It is an air leak test device that inspects the airtightness, sealing performance, and waterproofness of electrical equipment and packaging containers (cosmetics, food). It tests for leaks in products such as smartphones, tablet devices, keyless switches, wristwatches, bottle containers, and cosmetic containers (eyeliner, mascara).

【Leak testers and leak test-related products provided by Fukuda】 Please take a look at our catalog! ★ Millimeter-wave radar & LiDAR leak tester: The air leak tester "FL-610" for controlling the separate type leak tester air pressure unit "LPU-300." ★ Leak tester for simultaneous measurement of workpieces: Measures two workpieces with one unit. By comparing two at the same time, you can increase the number of operations. ★ Electric air regulator for blood pressure monitor pressure confirmation: Excellent in repeatability of pressure control and pressure adjustment. ★ Leak tester for automotive lighting: Can be tested at low pressure without affecting the workpiece (item under inspection). ★ Air leak tester conversion box/cable: Peripheral equipment for air leak testers. Used when replacing old models with current products or when changing the model of current products. ★ Waterproof inspection testing device: A device for testing the waterproofness (equivalent to IPX7,8) and sealing of sealed products. It can be used for various products such as electronic devices and packaging containers.
