RN73H1E Ultra Precision Chip Resistors
KOA's RN73H resistors feature high heat resistance, ultra-high precision tolerance, and enhanced moisture resistance
KOA Speer Electronics offers the 0402 (1E) size of the 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% ±5% RH, 1000 h) using 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 ppm/°C to ±50 ppm/°C. The 0402 (1E) offers a precision tolerance of 0.1% to 1.0% and a resistance range of 10 Ω to 300 kΩ. Additionally, the RN73H1E is AEC-Q200 qualified and is available with lead-free terminations to meet EU RoHS requirements.
These resistors are 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 or 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 0.063 W to 0.25 W, resistances up to 1 MΩ, and maximum working voltages between 50 V and 200 V.
