Product Description

The PTFR0603D21R0Q9 is a PTFR series thick film resistor designed as a compact 0603 SMD resistor with a resistance value of 21 ohm. Ideal for surface-mount applications, this resistor operates within a voltage range of up to 75V and tolerates a wide temperature span from -55°C to +155°C, making it suitable for industrial automation, automotive electronics, and consumer devices. With a power rating of 0.1W and ±1% tolerance, it ensures stable performance in high-density circuits. The PTFR0603 thick film resistor features excellent thermal stability and low noise, though its small size limits power dissipation capabilities. Constructed with robust materials, it supports reliable connections in modular designs without requiring direct communication interfaces. Its compact dimensions (1.6mm x 0.8mm) enable integration in space-constrained environments. This PTFR series resistor is widely adopted for precision signal conditioning, current limiting, and filtering applications.
