Product Description

The PTFR0402D1K78N9 is a precision 0402 1.78k Resistor from the PTFR Series Resistor family, designed for high-reliability applications. With a compact 0402 footprint (1.00mm × 0.50mm), it operates within a temperature range of -55°C to +155°C and handles up to 0.063W power rating at 50V maximum working voltage. Featuring ±1% tolerance and low temperature coefficient (TCR) of ±100ppm/°C, this thin-film resistor ensures stable performance in automotive electronics, industrial control systems, and medical devices. Its miniature size suits space-constrained PCB designs while maintaining excellent resistance stability under thermal stress. Limitations include limited power dissipation capacity compared to larger form factors. Compatible with standard reflow soldering processes, it complies with RoHS requirements for environmental safety.
