The MMA02040C1823FB300 is a high-precision surface-mount resistor engineered for high-resistance precision circuits, where accurate high impedance, tight tolerance, and compact size are critical. As a key component in its precision resistor series, it combines exceptional performance with an ultra-small form factor, making it indispensable in devices such as high-impedance sensor interfaces, precision amplifiers, and advanced measurement tools-trusted across medical, industrial, and scientific research sectors.
Electrical Specifications
At the core of MMA02040C1823FB300 is a 1.82 MΩ resistance value, directly decoded from "1823" in its part number (182 × 10³ Ω = 182,000 Ω = 1.82 MΩ). This high resistance is perfectly calibrated for critical high-impedance circuits: voltage dividers in electrostatic sensors, input stages in precision electrometers, and signal conditioning in low-current measurement systems-all scenarios where maintaining high impedance is essential to prevent signal loading and ensure measurement accuracy. The "F" designation guarantees a ±1% tolerance, ensuring minimal variance across production runs, a feature critical for calibration-sensitive equipment like medical imaging devices and scientific research instruments.
With a power rating of approximately 0.1W, it is optimized for low-power, high-impedance applications such as radiation detectors and environmental monitoring sensors, where energy efficiency and minimal power dissipation are paramount. It maintains stability across an impressive temperature range of -55°C to +125°C, performing reliably in extreme conditions-from cryogenic research setups to high-heat industrial enclosures. A low temperature coefficient of resistance (TCR) further minimizes drift with temperature changes, preserving accuracy in climate-fluctuating environments.
Physical Design
The "02040" in its part number confirms that MMA02040C1823FB300 utilizes an 0204 package (0.6mm × 1.0mm), one of the smallest surface-mount form factors available. This compact size is a game-changer for high-density PCBs in micro IoT sensors, compact medical probes, and high-precision measurement devices, where both high impedance and small size are required.
Crafted with high-grade metal film or thin-film materials on a low-loss ceramic substrate, the resistor is engineered to minimize leakage current and parasitic effects-critical for maintaining high resistance integrity. Its surface-mount design integrates seamlessly with automated assembly lines, while high-conductivity solderable terminations ensure secure connections in densely packed circuits without compromising high-impedance performance. Supplied in anti-static tape-and-reel packaging, it protects against electrostatic discharge (ESD) which can damage its delicate structure-essential for preserving its high resistance characteristics.
Applications
In medical electronics, MMA02040C1823FB300 is a cornerstone in EEG machines and high-sensitivity biosensors, where its 1.82 MΩ resistance and ±1% tolerance ensure accurate signal conditioning of weak biological signals, directly impacting diagnostic reliability. In scientific research, it is used in particle detectors and low-current measurement setups, enabling the detection of minute electrical currents with precision.
In industrial automation, it supports high-impedance sensor interfaces for humidity and gas detectors, ensuring that sensitive measurements are not distorted by resistor loading. For aerospace systems, its temperature stability makes it suitable for high-altitude sensors and communication modules operating in extreme atmospheric conditions, where maintaining high resistance accuracy is critical for data integrity.
Key Advantages
MMA02040C1823FB300 offers unmatched benefits: its 1.82 MΩ high resistance and ±1% tolerance deliver pinpoint accuracy for high-impedance circuits; the 0204 package enables integration into ultra-compact designs, a boon for miniaturized devices; low TCR ensures resistance stability across temperature swings, preserving measurement integrity; and premium materials guarantee minimal leakage current, maintaining high resistance performance. These features make it the go-to choice for precision-critical high-impedance applications.
