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. |
