Exxelia Ohmcraft : High Voltage Resistors for the World’s Most Advanced Medical Applications
Our resistors are designed for a variety of products to be used in medical diagnosis, treatment, and prevention. From small, implantable, and non-invasive devices, to large diagnostic imaging equipment, Exxelia Ohmcraft resistors are chosen by medical manufacturers because the operating environments are high voltage and magnetic fields where accuracy and stability are paramount.
Exxelia Ohmcraft’s proprietary Micropen® precision printing technology produces superior resistor products ideally suited for medical applications, printing resistors with electrical characteristics that outperform our competitors. Our technology allows us to write a very exact serpentine pattern with more precise line width and length than conventional screen printing.
Our Exxelia Ohmcraft serpentine patterned resistors produce superior electrical characteristics, including:
High Voltage (1 - 5 kV up to 50kV) Low Noise / High Ohmic Values
Superior TCR and VCR (25 < TCR < 200 ppm/°C)
Resistor Value (> 1 MΩ up to 10 TΩ)
Pulse Handling Capability
Tolerances to 0.1%
Medical Instruments and Equipment
Exxelia Ohmcraft is committed to enabling medical instrument and equipment manufacturers to continue miniaturizing their products without comprising on performance. Physicians and their patients rely on our resistors to maximize the functionality and reliability of designed for each device. Our unique Micropen® precision printing technology produces the pulse-handling capabilities needed for critical medical circuits. Exxelia Ohmcraft’s resistors are found in most defibrillators and across the spectrum of diagnostic imaging equipment.
