Conversion formula for electric and magnetic fields

The electric and magnetic field conversion formula using the free-space wave impedance of 377Ω applies only to far-field plane waves (EMC radiated nuisance, antenna far-field), and is not available for the near-field (coils, IF magnetic fields, near-field probes, near areas of shielded chambers). 377Ω ...

What standards need to be looked at for optocouplers or digital isolators for safe electrical isolation?

When optocouplers are used to protect a system from electrical damage, they must comply with, for example, DIN EN 60747-5-2 as well as DIN EN 60747-5-5, DIN EN IEC 60747-17 ...
