What dimensional tolerances are specified for the stainless steel disc spring height, and why is that important for coin cell assembly?
The disc spring height is specified with a tolerance of ±0.03 mm for certain configurations (e.g., 15.4 mm diameter, 1.20 mm height in 304 SS). This tight tolerance ensures consistent spring force and reliable internal contact support, reducing looseness in coin cell assemblies.
Which coin cell battery series and material grades are available for this disc spring, and how do they affect corrosion resistance?
The disc spring is available for 20, 24, and 30 series coin cells, with material grades of 304 and 316 stainless steel. 316 SS offers enhanced corrosion resistance compared to 304, making it suitable for more demanding environments or electrolyte compatibility.
This stainless steel disc spring (SKU AF-CC-S-SPRG-CO20-0015) is designed for 20 series coin cell applications, providing internal spring force to maintain contact and reduce looseness. The component is offered in 304 or 316 stainless steel and requires precise selection of diameter, height, and thickness for the intended assembly.
Positive
- Provides Spring Force for Contact Support: The disc spring delivers mechanical spring force to maintain internal contact within coin cell assemblies, reducing looseness and ensuring reliable electrical connection.
- Available in 304 and 316 Stainless Steel: The spring is offered in both 304 and 316 stainless steel grades, allowing selection based on required corrosion resistance and mechanical properties for the coin cell environment.
Trade-offs
- Requires Precise Dimension Selection: The disc spring must be selected with exact diameter, height, thickness, and battery series to match the specific coin cell assembly, as incorrect dimensions will compromise contact force and fit.
