The inrush current is dependent on the converter, the load (especially the capacitive load) and the impedance of the primary power supply. Therefore, there is no recommended value for the inrush limiting inductor as this need to be individually worked out for each application. Having said that, usually 22µH~100µH is a good starting point.
A CMC is a good inrush current limiter because the core does not go into saturation with high currents (the +ve inrush current is balanced out by the -ve inrush current), so it has a dual purpose: EMC filter and inrush limiting. However, for high power converters it is sometimes better to use a low inductance, high current, choke that is selected to reduce inrush rather than a high inductance choke selected for the best EMC filtering because otherwise too much power could be lost through the choke's resistance during normal operation.

Our AC/DC converters usually incorporate input surge protection, although some series require an external suppression MOV to meet all operating conditions. Our DC/DC converters do not usually incorporate surge protection, although an electrolytic capacitor placed close to the input pins is usually sufficient to meet the requirements of 61000-4-5.
We use a number of tin whisker mitigation strategies, all following the Jedec JP002 guidelines:
Through Hole Devices
The pins used in all of our through-hole converters are made of hard silver-copper alloy. The pins are then Nickel underplated to 0.5µm before being pure tin electroplated to 6µm thickness. This thickness of overplating is a compromise between reasonable manufacturing costs and having a thick enough coating to impair tin whisker formation. The surface is not ‘brightened’, also to mitigate tin whisker formation. Finally the pins are annealed according to JIS C3101. This reduces any residual forming stresses, which is one of the other potential causes of tin whisker formation.
Surface Mount Devices:
The carrier frames used in our SMD converters are made from DF42N nickel alloy which is pure tin plated. The pins are then hot dipped in Sn-Ag-Cu solder to mitigate tin whisker formation.

We use standard coated wire with both converters because the windings are physically separated (reinforced isolation). For the RP-xxxx series the primary and the secondary are separated by a chamber system. The RxxP(2)xx series uses a two chamber system which primary and secondary windings are separated by an insulated bridge on both sides of the toroidal transformer.
Energy-related Products: A term used in the EU Eco-design directive. Previously EuP, Energy-using Products.
Field Programmable Gate Array: A family of general-purpose logic devices that can be configured by the end-user to perform many different, complex, logic functions.
General Purpose Interface Bus: A standard bus for controlling electronic instruments with a computer. Also called IEEE-488 bus because it is defined by ANSI/IEEE Standards 488-1978, and 488.2-1987. Also called HP-IB, a trademarked term of Hewlett-Packard, who invented the protocol.
General Purpose I/O: A flexible parallel interface that allows a variety of test equipment (bench power supplies, meters, etc.) to be controlled by a central computer.
Internet of Everything. A superset of IoT that includes people, processes, data and IoT devices in one intelligent, networked fabric. IoE connects people in more relevant ways, delivers the right information to the right person or device at the right time and interprets data to allow useful decision making.
Abbreviated J: A measure of energy or work. One joule is one watt of power, applied for one second (a watt-second). The energy absorption capability of transient protection components (diodes, varistors, etc.) is measured in joules.
(MOV, or surge-suppressor): A discrete electronic component that diverts current from excessive voltage to ground in DC systems or neutral lines in AC systems. It is commonly used on the inputs of AC/DC power supplies to suppress differential input voltage surges. A MOV can divert and dissipate high energy, but reacts slowly and its breakover point is not well defined, so it is often used in combination with a transient suppressor diode that reacts quickly and has an accurate breakover voltage, but has limited power absorption characteristics. MOVs degrade with use.
If anything can go wrong, it will.
