We manufacture high voltage, high resistance thick film resistors in 7W, 10W, and 12W types.

利久電器本社

For those looking for alternatives to high voltage, high resistance thick film resistors, we manufacture metal glaze high megohm resistors in 7W, 10W, and 12W types starting from 100 pieces (lead time: up to 3 months). *These are similar size products from other companies. These are custom products utilizing the manufacturing technology of our RM series catalog lineup, so we can accommodate resistance values outside the standard series, special terminal shapes, and lead wire lengths. We will provide proposals tailored to your needs, so please feel free to contact us for more details.

Rikyu Electric's core technology: "Cutting"
We will introduce one of our core technologies, the cutting process, with accompanying illustrations.

This is the process of scraping off a coated ceramic core with a diameter of 1.7mm to 8.5mm and a length of approximately 2.5mm to 10cm using a disc-shaped cutter. We can accommodate a wide range of film types. There is also a possibility of handling core sizes other than those mentioned above. Please feel free to contact us.
Core technology of Riku Electric: "Lead Cap Welding"
We will introduce one of our core technologies, the lead cap welding process, along with illustrations.

This is the process of welding lead wires to caps made of iron and brass. We have production experience with cap inner diameters ranging from 0.99mm to 8.88mm and lead wire diameters from 0.4mm to 1.2mm. We also perform welding for large-diameter caps with inner diameters up to 31.7mm and special-shaped terminals. There may be possibilities for sizes other than those mentioned above, so please feel free to contact us.
