HPL Wound Ferrite Inductors TDK HPL Wound Ferrite Inductors feature high reliability without joints and magnetic flux cancellation, achieving low EMI. These inductors use ferrites made of LowLoss material and offer low DC resistance by frame forming. The HPL inductors are available in two variants that provide 220nH and 330nH of inductance. The operating temperature range including self-temperature rise is from -55°C to 155°C. Applications of these AEC-Q200 qualified inductors include adaptive driver assistance systems (ADAS).
