Ultra Precision Chip Resistor Offers Improved Moisture Resistance

KOA Speer Electronics introduces the 0603 (1J) size of their RN73H line of ultra precise thin film chip resistors. Featuring a moisture-resistant protective layer over the resistive film construction, the RN73H1J offers enhanced moisture resistance (85 °C +2, 85 percent +4 RH, 1000 hrs).

With a precision tolerance of +/-0.05% ~ +/-1.0%, a resistance range of 10 Ω ~ 1MΩ, power rating of 1/10W and T.C.R. values of ±-5 ~ ±100 ppm/°C, the 0603 package RN73H thin film resistor is designed for applications that require a reliable resistor for humidity and high temperatures to 155 °C.

RN73H1J chip resistors are ideal for applications within the transportation, medical, telecommunications, consumer electronics and industrial markets, especially in applications where high temperature/high humidity are a concern. Lead time is 12 weeks.

Other sizes of the KOA Speer's RN73H chip resistor series include 0402, 0805, 1206 & 1210 and feature a power rating range of .063W to .25W, resistances up to 1MOhm and maximum working voltages between 50V and 400V. The RN73H series is AEC-Q200 Qualified and available with lead-free terminations to meet EU RoHS requirements.
