Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

QC(Part Testing by IC Components)Quality Warranty

Frequently Asked Questions

Can RSA18DTAT be used as a direct replacement for another 36-position, 0.125 inch dual-edge card edge connector?
RSA18DTAT can be a practical replacement when the mating card uses a 0.062 inch thick, dual-edge, 36-position layout and the mechanical footprint matches the right-angle through-hole format. For RSA18DTAT, the main checks are card thickness, edge finger spacing, board-to-card orientation, and whether the flush-mount flange with 4-40 threaded insert matches the existing chassis or retention scheme.
What design checks should I make before using RSA18DTAT in a new board layout?
With RSA18DTAT, verify card insertion direction, keep-out space around the right-angle body, and hole pattern compatibility for the through-hole solder terminations. RSA18DTAT also needs enough board edge clearance for the dual-row contact access and enough mechanical support if the card will see repeated insertion cycles or vibration.
Is RSA18DTAT suitable for industrial or long-life equipment?
RSA18DTAT is often a reasonable fit for industrial designs because it uses phosphor bronze contacts, gold plating, PPS insulation, and is specified from -65°C to 125°C. In RSA18DTAT-based systems, long-life behavior still depends on mating cycle count, contamination control, card edge finish quality, and whether the connector is mechanically restrained against shock and vibration.
Can RSA18DTAT tolerate harsh temperature environments?
RSA18DTAT has an operating range of -65°C to 125°C, so it can fit many industrial, outdoor, and equipment-enclosure applications. For RSA18DTAT, the limiting factors are usually the PCB material, solder joint reliability, and the mating card’s own temperature rating rather than the connector body itself.
What card thickness should I design for with RSA18DTAT?
RSA18DTAT is intended for a 0.062 inch, or 1.57 mm, card thickness. If the card is thinner or thicker, RSA18DTAT may not maintain correct contact wipe, retention, or insertion force, so the card edge stack-up should be controlled carefully during PCB fabrication.
Is RSA18DTAT appropriate if my card only uses one edge or a different pin count?
RSA18DTAT is a dual-edge, 36-position connector, so it suits designs that intentionally route signals on both card edges. If your board only uses a single edge or a different contact count, RSA18DTAT may create unused contacts, awkward routing, or mechanical mismatch, and a single-edge or alternate-position connector is usually a better fit.
How does RSA18DTAT compare with lower-cost card edge connectors that do not use gold plating?
RSA18DTAT uses 10.0 µin gold over phosphor bronze contacts, which generally improves corrosion resistance and contact stability in compared-to-unplated or tin-only options. For RSA18DTAT, the trade-off is cost versus lower contact resistance drift and better behavior in low-level signal or less-controlled environmental conditions.
Can RSA18DTAT be used for low-level signals or mixed-signal boards?
RSA18DTAT can work for low-level signals if the layout keeps sensitive nets short, clean, and well-referenced, because the connector itself is not a controlled-impedance part. For RSA18DTAT, pay attention to contact resistance, return-path continuity, and contamination control if the interface carries small analog signals or logic-level data.
What should I consider if I want to migrate from another Sullins part to RSA18DTAT?
When migrating to RSA18DTAT from another Sullins connector, compare the base product family, flange style, opening geometry, and termination orientation rather than assuming footprint equivalence. RSA18DTAT may share the RSA18: family but still differ in mounting details that affect enclosure fit, retention hardware, or board spacing.
Is RSA18DTAT a good choice when the connector will be inserted and removed often?
RSA18DTAT can be used in serviceable systems, but repeated mating cycles should be evaluated against the card edge plating, insertion force, and the mechanical support of the PCB. With RSA18DTAT, repeated handling is better tolerated when the card is guided squarely and the board is not flexed during insertion.
Does RSA18DTAT need any special soldering or assembly considerations?
RSA18DTAT uses through-hole, right-angle solder terminations, so hole sizing, plating quality, and wave or selective solder access matter. For RSA18DTAT, assembly should avoid excessive thermal stress and should confirm that solder fillets are consistent on both rows to preserve mechanical strength.
When would RSA18DTAT not be the right connector choice?
RSA18DTAT is less suitable when the application needs a surface-mount connector, a different card thickness, a higher pin count, or a controlled high-speed interconnect with tight impedance requirements. In those cases, RSA18DTAT may introduce mechanical or electrical compromises that another connector family can avoid.
