New Ultra Precision Chip Resistor from KOA Speer Offers Improved Moisture Resistance

KOA Speer Electronics has introduced 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°C, 85%+4% RH, 1000 hrs).

With a precision tolerance of ±0.05% ~ ±1.0%, a resistance range of 10Ω ~ 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. The RN73H1J is AEC-Q200 Qualified.

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.

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part Two

Maxwell’s Equations are eloquently simple yet excruciatingly complex. Their first statement by James Clerk Maxwell in 1864 heralded the beginning of the age of radio and, one could argue, the age of modern electronics.

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 1MΩ and maximum working voltages between 50V and 400V. The RN73H series are available with lead-free terminations to meet EU RoHS requirements.
