The RC1206JR-0730KL is a 30 kOhms ±5% 0.25W, 1/4W Chip Resistor 1206 (3216 Metric) Moisture Resistant Thick Film manufactured by Yageo. This part is a chip resistor, meaning it is a miniature electronic component done in a thin layer of metal, usually on a ceramic substrate. It is also 1206 size, which is a specific size defined by the International Electronics Commission (IEC). The resistance value is 30 kOhms ±5%. It is designed to dissipate 0.25 watts of power. Additionally, it is a 1/4W Chip Resistor, which means it is designed to withstand a 1/4 watt of power. It is also moisture resistant, meaning it can withstand moisture either from its environment or from physical contact. Finally, it is manufactured by Yageo, a major manufacturer of electronic components.
