High Voltage Planar Resistors for Defibrillation Charge Control Circuit


TT Electronics’ High Voltage Planar Resistors were successfully placed in a defibrillation charge control circuit. The customer needed components that were physically smaller, had improved environmental performance and excellent linearity-combination of VCR and TCR, as well as long term stability under voltage stress. The customer worked with us because we offered improved resistor design/materials to reduce size and give excellent reliability/linearity. Its high density epoxy coating gave improved environmental performance.
