Product Description

The PTFR0402B21K0N9 is a 21kOhm thick film resistor from the PTFR series, designed as a compact 0402 SMD resistor for high-density PCB applications. This surface-mount component operates within a voltage range of up to 50V and supports a wide temperature range of -55°C to +155°C, ensuring stability in harsh environments. As a passive two-terminal device, it integrates seamlessly into analog/digital circuits for voltage division, current limiting, or signal conditioning. Its 0402 package (1.0mm x 0.5mm) enables space-efficient layouts for consumer electronics, automotive systems, and IoT devices. Featuring ±1% tolerance and low parasitic inductance, this resistor excels in high-frequency applications, though its small size limits maximum power dissipation to 0.063W. PTFR series resistors are widely used in power supplies, sensors, and communication modules requiring precision and reliability. The thick film technology provides excellent thermal stability and moisture resistance compared to carbon film alternatives.
