Featuring a dominant wavelength of 470nm to 475nm and a peak wavelength of 468nm, this LED delivers consistent blue color output with a typical luminous intensity of 15mcd at just 5mA forward current. The ultra-thin 0.55mm package height makes it particularly suitable for low-clearance and space-constrained designs such as thin-profile consumer electronics, wearable devices, and miniaturized instrumentation. The wide 130-degree viewing angle ensures uniform light distribution across the viewing area. Packaged in the industry-standard 0603 (1608 metric) footprint, the LTST-C191TBKT-5A is compatible with standard surface-mount assembly processes and automated pick-and-place equipment.","working_principle":"The LTST-C191TBKT-5A utilizes an InGaN (Indium Gallium Nitride) semiconductor chip as its light-emitting element. When forward-biased at a typical voltage of 2.8V, electrons in the InGaN active layer recombine with holes at the p-n junction, releasing energy as photons in the blue spectrum with a peak emission at 468nm. The water-clear rectangular lens encapsulates the chip and provides optical coupling with a wide 130-degree half-angle, ensuring broad and even light distribution. The device is designed for continuous operation at up to 20mA forward current, with a peak rating of 100mA for pulsed applications. The spectral line half-width of 25nm indicates a relatively narrow emission band, contributing to the vivid and saturated blue color appearance. Proper ESD handling precautions are recommended during assembly, as InGaN LEDs are sensitive to electrostatic discharge.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Anode (+)<\/td><td>Input<\/td><td>Positive terminal; connect to forward bias supply through current-limiting resistor<\/td><\/tr><tr><td>2<\/td><td>Cathode (-)<\/td><td>Ground<\/td><td>Negative terminal; connect to circuit ground<\/td><\/tr><\/table>","application_scenarios":"<ul><li>LCD display backlighting in smartphones, tablets, and portable electronics requiring thin-profile blue LEDs<\/li><li>Status and indicator LEDs on consumer electronics front panels, routers, and set-top boxes<\/li><li>Keypad and switch backlighting in industrial control panels and handheld instruments<\/li><li>General illumination in wearable devices and fitness trackers with height constraints<\/li><li>Interior automotive lighting including dashboard indicators and cabin ambient lighting<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Lite-On<\/td><td>LTST-C191TBKT<\/td><td>0603<\/td><td>Same LED, standard tape packaging without -5A suffix<\/td><\/tr><tr><td>Samsung<\/td><td>SPHWH2D3N01YE4<\/td><td>0603<\/td><td>Blue LED, 470nm, similar form factor<\/td><\/tr><tr><td>Kingbright<\/td><td>APHHS1005QBDZGKC<\/td><td>0402<\/td><td>Smaller footprint alternative, blue 470nm<\/td><\/tr><tr><td>Rohm<\/td><td>SML-D12M1WT86<\/td><td>0603<\/td><td>Blue LED, 468nm, similar package<\/td><\/tr><tr><td>Vishay<\/td><td>VLMU1500-GS08<\/td><td>0603<\/td><td>Blue LED, 470nm, comparable performance<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/2396","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=2396"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/2396\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=2396"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=2396"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=2396"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=2396"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
