Overview

Passive electrical components have an important role to play in ensuring the safe working of medical equipment, thereby protecting expensive devices from damage and also safeguarding human life. This study is about the critical role played by power resistors in the medical electronics industry.


KWK Resistors offers a wide range of resistive components for use in various medical devices. Our power resistors are the perfect choice to protect high value medical equipment from power surge and high voltage stress.

Our power resistors come with CE marking, and are used by major medical industry OEMs, both in India and across the world. All our resistor components are RoHS (Restriction of the Use of certain Hazardous Substances in Electrical and Electronic Equipment) compliant.

Some of the KWK resistor product series suitable for different application areas in the medical industry are listed below:

resistors for medical industry, resistors for medical equipment

Human contact devices

Devices that make physical contact with the human body include defibrillators, ECG/EEG machines, surgical devices Resistors used in such devices must be capable of handling power surges during short duration pulses. Especially in AEDs, if the surge energy is diverted away from the patient, it may propagate back into the defibrillator and damage sensitive monitoring inputs.

Lab equipment and instrumentation

Accurate and stable instrumentation in the medical field requires the ability to detect very small signals without producing false readings. Compact sizing is another important consideration to minimise the space requirement.

For instance, the input stage of an instrument with a resistive sensor (such as a thermistor) in a precision temperature-monitoring circuit consists of a bridge of resistors which must be closely matched in value.

Imaging and Diagnostics

Imaging applications are scanning devices such as X-ray, ultrasound, and MRI systems. Each of these sophisticated devices have specialised resistance requirements. For instance, X-ray machines require high voltage supply for X-ray generation. MRI scanners generate strong magnetic fields, so the resistors used have stringent restrictions for non-magnetic material to be used.
