SEI Offers New SMT High Voltage Chip Resistors for Medical Devices
2512 size chip resistor withstands voltages to 10Kv...
RALEIGH, NC (May 27, 2004) - Resistor manufacturer SEI Electronics, Inc. has expanded its resistive product offering to include a new surface mount, high voltage chip resistor capable of handling up to 10,000 volts. Designated the HVC Series, these thick film surface mount resistors exhibit superior power and voltage handling capabilities, making them ideal for use in medical applications.
Medical applications that require this technology include overvoltage protection for defibrillators, medical imaging systems, neurostimulators, ECG, analgesia syringe pumps, blood transfusion equipment and bladder control devices. Additionally, the HVC Series resistors can be used in high voltage power supplies for applications such as PET scanners, GAMMA cameras, radiation therapy systems and X-ray equipment.
"As medical designers move toward surface mount resistive devices, the HVC Series of resistors will replace axial leaded resistors in high voltage applications," said Kory Schroeder, SEI's Product Engineering Manager.
SEI is able to attain exponentially higher voltages through its precision fine film deposition process that allows for writing of thicker and higher quality resistive traces on a ceramic substrate. Other high voltage resistor manufacturers utilize crude screen printing processes, which tend to leach and thereby limit the amount of resistive material that can be printed on the substrate.
With the new extended range, the HVC Series resistors are now offered with limiting element voltages of 2500V, 5000V and 10,000V in 1206, 2010 and 2512 industry standard chip sizes, respectively. Power ratings for the three chip sizes range from 0.3W to 1W at 70 Deg C. Resistance values range from .1W to 2T W, with tolerances down to 1%. Operating temperatures range from 55°C to +150°C.
Typical pricing for the HVC series resistors range from $0.40 to $2.50 based on the production volumes. Lead times are from stock to 8-10 weeks.
