KOA Speer Electronics introduces the 0402 (1E) size of their RN73H line of ultra precision chip resistors. These thin film (metal) chip resistors feature high heat resistance (up to +155°C) and ultra high precision (±0.1%) tolerance. The RN73H offers enhanced moisture resistance (85°C ±2°C, 85% ±4% RH, 1000h) by the use of a special protective layer over resistive film construction.
The RN73H1E chip resistor also features a power rating of 1/16 (0.063) Watts and TCR values of ±10 ~ ±50 ppm/°C. The 0402 (1E) offers a precision tolerance of 0.1% ~ 1.0% and a resistance range of 10? ~ 300k?. Additionally, the RN73H1E is AEC-Q200 qualified and is available with lead-free terminations to meet EU RoHS requirements. Lead time is 12 weeks.
Used primarily as reliable precision resistors that are robust to humidity and high temperature (+155°C), RN73H1E chip resistors are ideal for applications within the transportation, avionics and medical markets, specifically any applications where high temperature/high humidity are design considerations.
KOA Speer's RN73H chip resistor series is available in a range of sizes, from 0402 (1E) to 1210 (2E). These chip resistors feature a power rating range of .063W to .25W, resistances up to 1MΩ and maximum working voltages between 50V and 400V.
