Key Features & Advantages

Universal Cell Compatibility: Accepts three standard 20 mm geometries (CR2032/2016/2025), reducing specialized inventory complexities in broad engineering projects.
Advanced Thermal Housing: Engineered from UL 94 V-0 PBT to withstand critical temperatures up to 200 °C without geometric distortion during wave soldering processes.
Elastic Manganese Steel Contacts: ASTM A298-compliant terminals maintain excellent mechanical elasticity and consistent electrical continuity during prolonged vibrational strain.
Through-Hole Structural Stability: Rigid PTH terminal legs lock securely into circuit topologies, providing superior mechanical resistance compared to surface-mount components.

APPLICATION SCOPE: Designed for industrial PLCs, smart home control modules, automotive electronic regulators, access control networks, backup surveillance power grids, and precision digital analytical instruments requiring standard IPC-A-610 tolerances.

PACKAGING: Dispatched in standard 10-unit protective packs for rapid prototype validation and equipment maintenance cycles. Large-volume production batching is supported with bulk shipping layouts. Custom enterprise branding is available for allocations exceeding 5,000 units.

IMPORTANT NOTICE: Adhere strictly to proper thermal parameters during wave soldering or manual assembly to preserve terminal tension. Ensure all components are handled in compliance with ESD-safe laboratory protocols. Store unused inventory in a dry, atmospheric-controlled space to shield terminals from ambient moisture oxidation.

Constraints

This battery holder requires soldering onto a PCB via through-hole terminals for secure electrical connection. The PBT housing imposes a maximum operating temperature of 200°C, and the holder is designed exclusively for CR2032, CR2025, and CR2016 coin cell batteries.

Soldering Requirements: The through-hole terminals must be soldered to the PCB using standard electronic assembly processes to ensure mechanical stability and electrical continuity.
Battery Compatibility: The holder accommodates only CR2032, CR2025, and CR2016 coin cell batteries of 20mm diameter and 3V nominal voltage.
Thermal Limits: The PBT housing must not be subjected to ambient temperatures exceeding 200°C during operation to prevent material degradation.
Vibration Resistance: Proper soldering ensures the holder resists loosening under vibration during device operation.

HowTo

Follow these steps to attach the battery holder to a PCB using through-hole soldering. Proper installation ensures secure electrical contact and mechanical stability.

Required Equipment: PCB with 20mm terminal spacing, Soldering iron, Solder

Position the holder on the PCB
Align the holder terminals with the corresponding through-holes on the PCB.
Insert the terminals
Insert the terminals fully through the holes until the holder base rests flush against the PCB surface.
Solder the terminals
Solder each terminal to its respective PCB pad using a clean, tinned soldering tip.

FAQ

How does the manganese steel terminal's mechanical elasticity ensure reliable electrical contact in battery holders subject to thermal cycling?

The manganese steel terminals deliver dependable electrical conductivity and mechanical elasticity, maintaining stable contact with battery electrodes even under conditions of vibration or temperature fluctuation. This prevents intermittent contact failures and ensures consistent power delivery in environments where thermal cycling is common.

Can this PTH coin cell holder accommodate both CR2032 and CR2016 batteries despite their different thicknesses?

Yes, the holder is designed to fit CR2032, CR2025, and CR2016 coin cell batteries, which have different thicknesses. The mechanical elasticity of the manganese steel terminals allows it to securely hold these varying battery sizes while maintaining stable electrical contact.

What safety certifications and quality standards does the Atomfair 20mm PTH coin cell battery holder meet?

The PBT housing complies with UL 94 V-0 flammability standards, ensuring operational safety in high-temperature environments. The manganese steel terminals meet ASTM A298 specifications, and dimensional accuracy conforms to IPC-A-610 electronic assembly standards for global PCB compatibility.

Assessment

This PTH coin cell battery holder provides broad compatibility with three common CR-series cells and uses a PBT housing rated for continuous operation up to 200°C with UL 94 V-0 flammability compliance, but requires through-hole PCB mounting and relies on manganese steel terminals that offer lower corrosion resistance compared to optional stainless steel or gold-plated variants.

Positive

Triple CR-cell compatibility: Accepts CR2032, CR2025, and CR2016 coin cells in a single holder design, reducing inventory requirements for multi-product manufacturing lines.
High-temperature PBT housing: Polybutylene terephthalate (PBT) body withstands operating temperatures up to 200°C and is UL 94 V-0 rated for flame retardancy, ensuring safety and dimensional stability in demanding environments.

Trade-offs

Through-hole mounting only: PTH terminals require drilled PCBs and wave or hand soldering; incompatible with surface-mount (SMD) assembly processes, increasing labor and board cost for high-density designs.
Manganese steel terminal corrosion: Standard terminals are manganese steel, offering good conductivity but limited corrosion resistance; for humid or chemically aggressive environments, upgraded 316 stainless steel or gold-plated terminals are recommended but not included in this variant.
