introduced several series of common-mode chokes for reducing unwanted
common-mode noise signals on a power line.
Comprising a total of 128 parts utilizing seven
different mounting packages, the SPCM series covers inductance values ranging
from 65.0uHy to 120mHy and current values ranging from 0.3ADC to 30Arms.
All of these common mode chokes utilize toroidal
core construction that offers a small size and reduced EMI. Mounting styles are
printed circuit board mount incorporating either through-hole or surface mount
Component orientation is configured for reduced
height or reduced board real estate. Many of these chokes incorporate a winding
separation spacer that provides 1 - 3 mm creepage distance for safety agency
compliance, and all units use UL94V0 materials.
Pricing ranges from $1.39 to $5.67 in production
