Typ. Max. Iv (µcd) Per Segment Min. Typ. REMARKS : 1. The average luminous intensity is obtained by summing the luminous intensity of each segment and dividing by the t otal number of segments. 2. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE (International Commissi on on Illumination) eye-response curve. 3. Clean only by pure water, isopropanol, ethanol, Freon TF (or equivalent). DESCRIPTION: The KWT-541 series is 0.54 inch (13.72mm) height 14-segment dual digit alphanumeric displays with the right DPs. This series is suitable for use in instrument panels, digital readout displays. All devices are available as either common anode or common cathode.
