Note for all types:
A single degaussing coil may be replaced by two coils in parallel.
E.g. a single coil of 10 can be replaced by two 20 coils in parallel,
one conected to terminal A the other to terminal C.
1) T: Thermoplast housing; D: Duroplast housing
2) SD: Standard decay behavior; LD: Long decay behavior
