Designed to prevent light bleeding, the H455C Series consists of completely recessed T1 (3 mm) LEDs that provide an integrated light shield and clearly visible light indication for on/off status. At 0.650" high, less than 1U at 0.750", the assemblies are 0.190" shorter than previously available designs and 2/10" smaller than industry standards. Unit width is 0.170" and rating is UL94V-0. The series provides 3 mm indication in one standard rack space to allow use in every rack without requiring a 2 mm sub-miniature LED. Maximum space saving efficiency is enhanced by a proprietary lead retention design for precise elevation and insertion accuracy. The H455C Series assemblies come in ultra blue, ultra white and bi-color as well as all industry-standard colors ranging in peak wavelengths from 430 to 700 nm. Low current and 5V styles are well-suited for emerging portable and low power products. Price is $0.69 each in production quantities for a quad-level unit in standard colors.
