The UNI-ROYAL 1206W4F3000T5E is a 300Ω surface-mount thick film resistor featuring ±1% resistance tolerance and a 0.25W (1/4W) power rating. Designed in a standard 1206 (3216 metric) package, this chip resistor provides reliable electrical performance and is suitable for automated SMT assembly and PCB applications.
With a maximum working voltage specification of 200V, a temperature coefficient of ±100ppm/°C, and an operating temperature range of -55°C to +155°C, the resistor is suitable for current limiting, voltage dividers, signal conditioning, and general-purpose electronic circuits. Actual operating voltage must remain within the resistor’s power rating.
