High reliability with airtight sealing!
The "CRD E Series" uses elements that provide stable constant current characteristics in a compact size. It is a small device that employs a DO-35 style DHD (Double Heatsink Diode) structure with a DO35 (300mW) package. With hermetic sealing for high reliability, the component materials are inexpensive and excellent for mass production. Previously, the series had a maximum of "E-153 (15mA)," but "E-183 (18mA)" has been added. This allows for the supply of a constant current that does not exceed the rated current, making it possible to stabilize the brightness of high-brightness LEDs rated at 20mA with a single component.

Company information
SEMITEC Corporation is a manufacturer of thermistor elements, thermistor sensors, and surge absorbers. Its features include a rich variety of thermistor elements in its lineup and the ability to provide thermistor sensors that are processed into optimal shapes for specific applications. The company has a proven track record of adoption across a wide range of fields and applications, including medical, office automation, home appliances, automotive, and industrial machinery. Additionally, SEMITEC Corporation manufactures and sells thermistors called "FT Thermistors," which are produced using a unique thin-film technology that combines traditional ceramics manufacturing methods with semiconductor technology. This unique thin-film technology enables miniaturization, fast response, and high heat resistance, and these thermistors have already been adopted as standard sensors in copiers and printers, as well as in many applications such as sensors for catheters and thermometers. For its global expansion, the company has manufacturing bases in Japan, South Korea, the Philippines, and Vietnam, with three locations in China, and sales offices in Japan, China, Taiwan, South Korea, and the United States, allowing for rapid product supply. *The company changed its name from Ishizuka Electronics Co., Ltd. in March 2011.
