The RK73H1ETTP1001F is a precision thick film chip resistor manufactured by KOA Speer Electronics, part of the RK73H series. It features a resistance of 1.0 kOhm with \u00b11% tolerance in a compact 0402 (1005 Metric) surface-mount package. With a power rating of 0.1W (1\/10W), temperature coefficient of \u00b1100 ppm\/\u00b0C, and maximum working voltage of 75V, this resistor is AEC-Q200 qualified for automotive applications. The ‘TP’ designation indicates punched paper taping packaging, and the device operates reliably over a temperature range of -55\u00b0C to +155\u00b0C.<\/p>\n

With a resistance of 1.0 kOhm, \u00b11% tolerance, and \u00b1100 ppm\/\u00b0C temperature coefficient, this resistor is designed for space-constrained applications requiring precise resistance values. The 0402 package occupies only 50% of the board area compared to 0603, making it ideal for high-density PCBs in smartphones, wearables, and IoT devices. AEC-Q200 qualification confirms automotive-grade reliability despite the miniature package size.","working_principle":"The RK73H1ETTP1001F operates as a passive thick film resistor:\n\n1. Resistive Element: A metal glaze thick film is screen-printed onto the alumina ceramic substrate and fired at high temperature. The 1.0 kOhm value is achieved through precise control of film composition and laser trimming.\n\n2. Precision Control: The \u00b11% tolerance and \u00b1100 ppm\/\u00b0C TCR are maintained through tight process control and laser trimming during manufacturing.\n\n3. Power Derating: Full 0.1W rating available up to 70\u00b0C ambient. Above 70\u00b0C, power decreases linearly to zero at 155\u00b0C.\n\n4. Voltage Limitation: The effective working voltage is the lesser of sqrt(P x R) and 75V maximum.","pin_description":"\n
