KOA Speer Electronics offers ultra precision chip resistors in 0402 (1E) size for RN73H wire. These thin film (metal) chip resistors have high heat resistance (up to +155°C) and ultra-high precision (±0.1%) tolerances. The RN73H provides enhanced moisture resistance (85°C±2°C, 85%±5% RH, 1000 hours) using a special protective layer over a resistant membrane structure.
The RN73H1E chip resistor also has a 1/16(0.063) watt power rating and a TCR value of ±10 ppm/°C to ±50 ppm/°C. The 0402 (1E) offers precision tolerances from 0.1% to 1.0% and resistance ranges from 10 ohm to 300k ohm. In addition, the RN73H1E is AEC-Q200 qualified and is available with lead-free terminals to meet EU RoHS requirements.
These resistors are primarily used for reliable precision resistors that are strong in humidity and high temperatures (+155°C). The RN73H1E chip resistor is ideal for applications in the transportation, avionics, and medical markets, especially for any application with high temperature or high humidity 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 have rated power ranges from 0.063 W to 0.25 W, resistances up to 1 milliohm, and maximum operating voltages between 50 V and 200 V.
