The TDK Group is excited to introduce the latest addition to its family of EPCOS MEMS pressure sensors—the C33 series. This automotive-grade sensor boasts an ultra-compact size of just 1 mm x 1 mm x 0.4 mm, making it the smallest in its class. It offers an absolute pressure measurement range from 1.2 bar to 10 bar and has been rigorously tested and certified under AEC-Q101 standards, ensuring reliability in demanding automotive environments. The sensor typically operates at 3V, but when powered with 5V, it delivers a sensitivity ranging from 15 mV/bar to 80 mV/bar, depending on the specific model. With an operating temperature range of -40°C to +135°C, it can also withstand short-term exposure up to 140°C. Additionally, the C33 series features exceptional long-term stability, with an accuracy of ±0.35% FS, making it ideal for applications where precision and durability are critical.
For consumer and IoT applications, the C39 series stands out with an even smaller package size of 0.65 mm x 0.65 mm x 0.24 mm. Its ultra-low profile makes it perfect for space-constrained devices like smartphones, wearables, and other compact electronics. The C39 measures absolute pressure at 1.2 bar and shares the same high level of long-term stability as the C33, with an error margin of only ±0.35% FS. All models in the series operate using a piezoelectric principle, producing an analog output that is proportional to both the measured pressure and the supply voltage, via a Wheatstone bridge configuration.
