Product Description

The PTFR0402D21K0N9 is a compact 21K Ohm chip resistor from the PTFR series, designed for surface-mount applications. It features a 0402 package size (1.0mm x 0.5mm) with a standard 1/16W power rating, operating within a voltage range of up to 50V. The resistor functions as a passive component without direct I/O connections or communication interfaces but integrates seamlessly into circuits for voltage division, current limiting, or signal conditioning. It operates reliably across a temperature range of -55°C to +155°C, making it suitable for automotive, industrial control, and consumer electronics. Key advantages include high precision (±1% tolerance), excellent stability, and miniaturized form factor, while limitations include limited power handling. Compatible with automated assembly processes, it ensures robust performance in space-constrained designs.
