Isolation Transformer

Part number 1 Inductance (µH) 2 DCR max (Ω) 3 Isolation
Voltage (Vrms) 4
Irms (A) 5

Common Mode Choke

Part number 1 Inductance (µH) 2 DCR max (Ω) 3
HPF2187L_ 10 0.15
Notes
  1. When ordering, please specify packaging code: e.g. HPX2126LD, HPF2187LC
  2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc.
  3. DCR is for each winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Isolation is measured from primary to secondary of each transformer.
  5. Current flowing through each secondary that causes a 20°C temperature rise from 25°C ambient

Termination:

  • RoHS Tin-silver-copper over tin over nickel over phos bronze. Other terminations available at additional cost.

Packaging:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (300 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • 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 D.
