The Coilcraft LPD4012 series comprises low-profile common mode chokes designed for common- and differential-mode filtering in power and signal line applications, with a compact size of 4 mm × 4 mm × 1.1 mm. Each device offers 100 Vrms winding-to-winding isolation for one minute and operates over an ambient temperature range of -40°C to +125°C, meeting AEC-Q200 Grade 1 requirements. The LPD4012-682 variant has a nominal inductance of 6.8 µH per winding, a maximum DC resistance of 0.53 Ω, and a rated current of 0.60 A, causing a 40°C temperature rise at ambient. The component includes RoHS-compliant matte tin over nickel over silver terminations, is halogen-free, and supports up to 600 MHz differential mode cutoff frequency. It is packaged on 7" or 13" reels with embossed plastic tape, and has a moisture sensitivity level of 1.
Coilcraft LPD4012 Series common mode chokes provide both common mode and differential mode filtering in a single miniature, low-profile device.
