MSD7342 Series

Common Mode Chokes

RoHS compliant AEC-Q flag
Our MSD7342 Series common mode chokes provide both common mode and differential mode filtering in a single device. They are ideal for use in both power line and signal line applications, providing 200 Vrms, one minute winding-to-winding isolation.
  • Common mode and differential mode filtering in a single device
  • Ideal for use in both power line and signal line applications
  • Up to 230 MHz differential mode cutoff frequency
  • 200 Vrms, one minute winding-to-winding isolation
Refer to Designing Common Mode Filters for design guidance.

Notes
  1. When ordering, please specify termination and packaging codes: e.g. MSD7342-105MLC
  2. Frequency at which the differential mode attenuation equals 3 dB
  3. Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
  4. Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
  5. DCR is for each winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. Interwinding isolation (hipot) tested for one minute.

Termination:

  • L = Matte tin over nickel over phos bronze.
  • T = RoHS tin-silver-copper (95.5/4/0.5)(Special order, added cost)
  • S = non-RoHS tin-lead (63/37)(Special order, added cost)

Packaging:

  • C = 7″ machine-ready reel. EIA-481 embossed plastic tape (250 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
  • B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
