MacDermid Alpha Micromax 5418 Platable Silver Palladium C1 Termination for Chip Resistors
Type: Platable Ag/Pd C1 Termination
Application: Chip Resistor
Pd Content: 18%
Shelf Life: 6 months
Micromax 5418 is a platable silver palladium C1 termination for chip resistor applications. Its 18% Pd content supports superior sulfur resistance, and blending with Micromax 5421E (0.5% Pd) lets you design the target Pd percentage. Cadmium, lead, nickel, and phthalate free, with high acid resistance and excellent solder leach resistance in lead-free solder.
Micromax 5418 from MacDermid Alpha is a platable silver palladium C1 termination paste developed for chip resistor applications. It is positioned as a high performance and green product, with lead, cadmium, nickel, and phthalate not intentionally added. The 18% Pd content delivers superior sulfur resistance, which matters in harsh environments and automotive-grade components. If a different Pd percentage is required, 5418 can be blended with Micromax 5421E (0.5% Pd) to design the target composition.
The paste carries 75–77% solids, fineness of grind at ≤20 μm and ≤10 μm, and a viscosity range of 220–290 Pa.s. Micromax 4553 is the listed solvent or thinner. Firing follows the standard Micromax profile of 850°C peak with a 10-minute holding time on a 30-minute cycle. Solder compatibility covers lead-free solder with excellent solder leach resistance. The termination is compatible with Micromax 00X1Z (00X0) and OFxxA resistor series. Store sealed at 5–30°C; unopened shelf life is 6 months.

Frequently Asked Questions
Why does 5418 use 18% Pd?
The 18% Pd content is what gives 5418 its superior sulfur resistance. That matters when the termination is exposed to sulfur-containing environments, which can attack silver-rich terminations over time.
How can I adjust the Pd percentage in 5418?
The TDS allows blending 5418 with Micromax 5421E, a 0.5% Pd conductor. This gives you freedom to design the target Pd percentage without switching to a different termination platform.
Which resistor series are compatible with 5418?
The TDS lists compatibility with the Micromax 00X1Z (00X0) and OFxxA resistor series. This makes 5418 suitable for a range of chip resistor builds that already use those resistor systems.
Does 5418 work with lead-free solder?
Yes. The product benefits list excellent solder leach resistance with lead-free solder. Combined with the lead-free and cadmium-free positioning, this supports lead-free chip resistor assembly.
What is the recommended firing profile for 5418?
The standard Micromax profile: 850°C peak with 10-minute holding time on a 30-minute total cycle. Ascending rate from 200°C to 500°C is 100°C/min, and descending rate from 700°C to 300°C is 85°C/min.
Is 5418 free of cadmium, lead, nickel and phthalate?
Per the TDS, cadmium, lead, nickel, and phthalate are not intentional ingredients and are not intentionally added. Trace amounts may be present. Customers with strict compliance thresholds should verify against their own requirements.
What thinner should be used with 5418?
Micromax 4553 is the listed solvent or thinner. Using the recommended thinner helps keep viscosity and application behavior consistent with the TDS values.
