  2. IC Electrostatic surge Thick Film Flat Chip ResistorsSurge Current Flat Chip Resistors (SG73 series) • Features • Excellent surge resistance • Applications • ESD & Surge protection at I/O port

  3. Thick Film Flat Chip ResistorsSurge Current Flat Chip Resistors (SG73S，SG73P series) • Features • High precision type (+/-0.5%~) • SG73S: Excellent ESD resistance High peak voltage, but effective for short duration waveform • SG73P:Strong resistance to pulse overload High peak voltage, but effective for long duration waveform (CR discharge/inrush current) Applications • ECUs, Circuits to catch inductive lighting surge.

  4. ＜ SG73P/SseriesAnti-pulse chip resistors＞ ◆Surge overloadHigh peak voltage, short duration Ex.：CR discharge, ESD surge ◆Pulse overloadHigher power than rated power, lower voltage than surge is applied for long time.Ex.：Gate resistors of FET SG73S Voltage SG73P 0 100ns~1us 1us~1ms Time
