Product Description

The PTFR0402D1K21P9 Resistor is a compact PTFR Series 0402 Chip Resistor designed for precision circuit applications. This surface-mount component offers a resistance value of 1.21KOhm (PTFR0402 1.21KOhm Resistor) with ±1% tolerance, operating within a voltage range of 0.05V to 50V and a temperature range of -55°C to +155°C. Its 0402 package (0.04" x 0.02") enables high-density PCB layouts while maintaining stable performance in automotive, IoT, and industrial control systems. The resistor features nickel barrier contacts for reliable solderability and anti-sulfur protection, making it suitable for harsh environments. Key advantages include low thermal EMF (<3µV/°C), moisture resistance (J-STD-020 compliant), and a power rating of 0.063W. Limitations include limited current handling due to compact size and sensitivity to mechanical stress in extreme conditions.
