Datasheet

KOA Speer Electronics has today announced the release of 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 10Ω ~ 300kΩ. 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.
