Thick Film Resistor in Medical Equipment

Thick film resistors are crucial components in a wide range of medical equipment. Their ability to provide stability, accuracy, and reliability makes them indispensable in devices that require precision and long-term durability. As medical technology continues to advance, especially with the growing trend of wearable and portable devices, the demand for high-performance resistors like thick film resistors will continue to rise. Below are some key applications of thick film resistors in the medical industry:

Patient Monitoring Systems

Diagnostic Equipment

Medical Imaging Devices

Pacemakers

Infusion Pumps

Therapeutic Equipment

Diagnostic Sensors

Laboratory Equipment

Surgical Instruments

Portable Medical Devices 

The customer, a leading manufacturer of medical diagnostic equipment, was developing a new portable ECG (electrocardiogram) device. The device needed to be both compact and reliable, with precise signal processing capabilities. The challenge was to incorporate resistors that could ensure accurate measurements over long periods of use, despite the variations in temperature and humidity that often occur in medical environments.

We worked closely with the customer to design thick film resistors that would provide exceptional accuracy and stability for ECG signal processing. These resistors were designed with a tight tolerance of ±0.5%, ensuring that even the smallest variations in electrical resistance wouldn’t interfere with the device’s performance. The resistors were made from high-quality ceramic substrates that could withstand fluctuations in temperature (from 0°C to 60°C) and humidity (up to 95% RH), which are common in medical environments.

We conducted extensive testing to meet medical industry standards. Each batch of resistors underwent accelerated life testing, simulating 10 years of use, to ensure the components could withstand continuous operation without failure.

• The custom thick film resistors provided the necessary precision and stability, ensuring the ECG device consistently delivered accurate readings, even in challenging environmental conditions.
• The compact design of the resistors helped the customer reduce the size of the ECG device by 20%, allowing for a more portable and user-friendly product.
• With the reduced failure rates (down by 15%), the customer was able to minimize product returns and enhance product longevity.
• By streamlining the procurement process and providing a reliable, high-quality solution, we helped the customer meet their production deadlines and reduce time-to-market by 10%.
