MLCC Termination Options

Termination Type Barrier to Prevent Solder Leaching RoHS Primary Applications
Ni/Sn Ni Yes All solder applications where RoHS is required. This is Johanson’s standard termination used by the largest number of customers. Most likely to be in stock at Johanson or at Johanson authorized distributors.
Ni/SnPb Ni No Military applications where the lead (Pb) mitigates Tin whisker growth.
Flexterm Ni/Sn Ni Yes Flexible terminations for high physical stress applications
Flexterm Ni/SnPb Ni No Flexible terminations for high physical stress applications
Ni/Au Gold Termination Ni Yes Parts are epoxied in place or a mix of solder and epoxy attachment is used. Controlled Au thickness to avoid Gold embrittlement issues when soldering. Premium price.
Cu/Sn(Copper barrier) Cu Yes This non-magnetic termination is best suited for application where very high inductance / magnetic fields are present. Use where RoHS is required. Most common non-magnetic termination.
Cu/SnPb(Copper barrier) Cu No This non-magnetic termination is best suited for application where very high inductance / magnetic fields are present.
PdAg None Yes No plating - solderable thick film PdAg alloy termination.Premium price.
PtAg None Yes No plating - solderable thick film PdAg alloy termination. Premium price.

Single Layer Termination Options

Termination Type Barrier to Prevent Solder Leaching RoHS Primary Applications
TiW/Ni/Au Ni Yes Chip & Au wire where capacitor is soldered in place or a mix of solder and epoxy attachment is used.
TiW/Au None Yes Chip & Au wire where capacitor is epoxy attached.Optimum termination for wirebonding. Cannot solder this chip as substantial leaching will occur.

Lead-Frame Termination Options

Termination Type Barrier to Prevent Solder Leaching RoHS Primary Applications
Ni None Yes Used in very high-temp applications
Cu/Ni/SnPb Ni No Typically used in military applications
CuSn6 Phosphor Bronze Ni No SnPb plate
Iron-Nickel Alloy Ni Yes Sn plate
Pure Silver Leads None Yes Used in very high power RF. Premium price.
