WA8351-AL Ultrasonic

Sensing Transformer

RoHS compliant halogen free AEC-Q flag
  • Compact, low-profile package (8.2 × 6.6 × 5.4 mm)
    reduces board space by up to 20% and is 24% shorter than competitive options
  • Optimized for the Texas Instruments PGA460-Q1
  • Ideal for a variety of available ultrasonic transducers
  • Excellent temperature stability up to 125°C
  • High performance for ultrasonic time-of-flight (TOF) sensing
  • AEC-Q200 Grade 1 (−40°C to +125°C)
  • Ideal for automotive ADAS and industrial applications such as liquid level sensing, flow sensing, or fluid identification

  1. When ordering, please specify packaging code: WA8351-ALC
  2. Inductance is tested between pins 4 and 6 at 100 kHz, 1.0 Vrms, 0 Adc.
  3. DCR is with the primary windings connected in series and the secondary windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Leakage inductance is measured between pins 4 and 6 with all other pins shorted.
  5. 500 Vrms, one minute isolation (hipot) between primary and secondary.
