What is the gold layer thickness and purity on the Atomfair gold-plated stainless steel coin cell spacer, and how does it affect contact resistance?
The spacer features a double-sided gold plating of pure gold with 99.9% purity and a thickness of less than 1 µm. This thin, high-purity gold layer provides a stable, low-resistance contact surface for coin cell assembly, while the underlying 304 stainless steel base ensures mechanical strength.
Can this 15.5 mm diameter spacer be used with standard 2032 coin cells, and what are the dimensional tolerances?
The spacer has a diameter of 15.5 mm and a thickness of 0.5 mm, which is compatible with standard 2032 coin cell hardware. The product description specifies a smooth, flat surface with no obvious burrs, but it does not state exact dimensional tolerances, so you should confirm the spacer diameter and thickness with the supplier before ordering.
What are the handling and storage requirements for the gold-plated coin cell spacer to prevent surface contamination or damage?
The spacer is supplied in a package of 10 pieces per bag, and the gold-plated surface should be handled with care to avoid scratching or contamination. The product description does not specify additional storage conditions, but standard practice for gold-plated components is to keep them in a clean, dry environment to preserve the integrity of the plating.
The Gold-Plated Stainless Steel Coin Cell Spacer (15.5 mm x 0.5 mm) provides a gold-coated 304 stainless steel internal contact and spacing element for coin cell assembly, offering low contact resistance and corrosion resistance from the 99.9% pure gold layer, though the sub-micron gold thickness may be prone to wear under repeated handling.
Positive
- Double-sided 99.9% gold plating: The pure gold coating on both sides provides low electrical contact resistance and corrosion resistance, critical for consistent coin cell performance.
- Rigid 304 stainless steel core: The 304 stainless steel base ensures mechanical rigidity and dimensional stability, with a smooth, burr-free surface for uniform spacing in coin cell stacks.
Trade-offs
- Thin gold layer (<1 µm): The gold layer thickness below 1 µm may be susceptible to mechanical wear or abrasion during repeated assembly or handling, potentially exposing the underlying steel.
- Fixed size and package quantity: The spacer is offered only in a single diameter (15.5 mm) and thickness (0.5 mm) with a fixed 10-piece package, limiting flexibility for non-standard coin cell configurations or larger batch requirements.
