The MMA02040C4700FB300 is a high-precision surface-mount resistor designed to deliver exceptional accuracy in compact precision circuits, where low resistance, tight tolerance, and miniaturized size are essential. As part of a renowned series of precision resistors, it combines reliable performance with an ultra-small form factor, making it a key component in devices like current sensors, precision amplifiers, and compact measurement tools-used in medical, aerospace, and industrial automation industries.
Electrical Specifications
MMA02040C4700FB300 features a resistance value of 47 Ω, clearly indicated by "4700" in its part number (4700 × 10⁰ Ω = 47 Ω). This low resistance is well-suited for circuits such as current sensing in battery management systems, shunt resistors in precision amplifiers, and voltage dividers in low-power sensors-common in applications where accurate current or voltage measurement is critical. The "F" in the model number denotes a resistance tolerance of ±1%, ensuring minimal variation across production batches, which is vital for calibration-sensitive devices like medical monitors and aerospace sensors.
It supports a power rating aligned with its compact size, typically around 0.1W, making it suitable for low-power, high-precision circuits in portable devices such as wearable health trackers and miniaturized data acquisition systems. The resistor operates reliably across a wide temperature range, often -55°C to +125°C, ensuring stability in extreme environments from freezing outdoor sensors to high-heat industrial control units. Additionally, it boasts a low temperature coefficient of resistance (TCR), minimizing resistance drift with temperature changes-critical for maintaining measurement accuracy in climate-sensitive applications.
Physical Design
The "02040" in the part number indicates that MMA02040C4700FB300 uses an 0204 package (0.6mm × 1.0mm), one of the smallest surface-mount form factors available. This ultra-compact size is ideal for miniaturized devices like micro IoT sensors, compact medical probes, and high-density circuit boards, where board space is extremely limited but precision cannot be compromised.
Constructed with high-quality metal film or thin-film materials on a stable ceramic substrate, the resistor offers excellent mechanical durability and corrosion resistance, withstanding vibration and moisture-key for long-term reliability in harsh operating conditions. Its surface-mount design facilitates automated assembly in large-scale production, while solderable terminations with high conductivity ensure secure connections even in densely packed PCBs. The resistor is typically supplied in tape-and-reel packaging, integrating seamlessly with high-precision pick-and-place machines for efficient manufacturing.
Applications
In medical electronics, MMA02040C4700FB300 excels in portable infusion pumps and blood pressure monitors, where its 47 Ω resistance and ±1% tolerance enable accurate current sensing, ensuring precise control of device operations and reliable patient data. In aerospace systems, it is used in fuel flow sensors and pressure transducers, where its temperature stability and low TCR maintain measurement precision in extreme atmospheric conditions.
In industrial automation, it supports current monitoring in precision motor drives and control circuits, enabling accurate feedback for motor speed regulation in semiconductor manufacturing and robotics. For consumer electronics such as smart home sensors and portable audio devices, it contributes to low-noise signal paths, enhancing measurement accuracy and device performance.
Key Advantages
MMA02040C4700FB300 offers several standout benefits: its 47 Ω low resistance and ±1% tolerance provide precise performance for current sensing and low-power circuits; the 0204 package enables integration into ultra-compact designs, perfect for miniaturized devices; low TCR ensures resistance stability across temperature fluctuations, critical for measurement accuracy; and its high-quality construction ensures long-term reliability, making it a trusted choice for precision electronic systems.
