RS Pro 104553

Electronic components and automation solutions from RS Pro has been offering no compromise between quality, price and efficiency since 1937. Quality is the company’s passion, that is why every item gets audited, inspected and tested for compliance with internal and international standards by highly qualified engineers.T-1 (4mm) Bi-PinA range of T-1 1\/4 (4mm) Bi-pin filament indicators, specifically intended for illumination in confined spaces, e.g. meters, switches, etc.Body color coding: White (6V), Yellow (12V), Green (24V), 14V and 28V color coding not applicableWire-Ended & Bi-PinFilament lamps will perform to specification and give optimum life when:,a) They are powered at the rated voltage from a stabilized 50Hz ac supply,b) Ambient temperature is in the range 20 to 25°C,c) No mechanical vibration is present.,Deviations from these criteria can have a significant effect on lamp life, particularly with low current filaments (80mA). Operation from a dc supply at rated voltage can reduce specified life by up to 50%. The effect of variation from the rated operating voltage should be noted: 5% above will reduce lamp life by up to 50%. 5% below will significantly increase lamp life. Current consumption can vary by up to ±10% on stated values at rated supply voltage. Care therefore should be exercised when running a number of lamps in series. In such applications it is recommended that the rated voltage be reduced by 10% to prevent premature failure of individual lamps.
