TDK SPM-HZR Inductors are magnetic shield-type wire wound inductors for power circuits that offer low inductance ranging from 0.47μH to 68μH with a tolerance of ±20%. These inductors use a metallic magnetic material and are integrated with a molded coil, that gives less humming noise when compared with ferrite core adhesive coils. The SPM-HZR inductors offer a measuring frequency of 100kHz and achieve a large current, low DC-resistance, and compactness when compared to ferrite wound-type inductors. These inductors show low inductance variance in high-temperature environments with good DC superimposition characteristics at a temperature range of -40°C to 125°C. The SPM-HZR inductors are ideally used in automotive-related equipment like car navigation, car audio, and so on.
