ERJ-14BQFR30U 0.3 Ohm 1210 Current Sense Chip Resistor

ERJ-14BQFR30U is used in current measurement paths where low resistance supports sense accuracy with minimal voltage drop. It can be used in power rails, battery monitoring, and driver stages that rely on stable shunt behavior for protection and control. Resistance is 0.3000 Ω with 1% tolerance for cleaner calibration in sense-and-limit loops. The 1210 chip size (3.2 x 2.5 mm) supports practical routing and robust solder fillets on higher-current nodes. Power rating is 0.5 W to handle dissipation during continuous monitoring. Temperature coefficient is 0 to +200 x 10⁻⁶/K, which helps keep readings consistent as the board warms. ERJ-14BQFR30U is often placed close to the sense amplifier to reduce trace error and noise pickup. It also helps limit copper trace heating. Request a quote for ERJ-14BQFR30U.
