The CSER2512FR30Q9 Low/Current Sense Resistors with Surface Mount 0.03Ohms ±1% 2W 2512 RoHS by ResistorToday are small, surface-mounted resistors with a resistance value of 0.03 ohms, or 30 milliohms. Because of their small size, they are ideal for applications where components need to be placed in tight spaces. The precision of these resistors (±1% tolerance) ensures accurate signals, readings, and dissipate energy (2W) without any worry about excessive heat buildup. This product is RoHS compliant, meaning it doesn't contain any hazardous substances such as lead or mercury. As a result, it is a safe, environmentally-friendly option when choosing resistors for your projects.
