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.

Frequently Asked Questions

Is GCA44DTKS suitable for a 0.062" (1.57 mm) backplane or daughtercard, or do I need to verify anything beyond thickness?
GCA44DTKS is specified for a 0.062" (1.57 mm) card, so it is a direct fit only when the PCB thickness and edge plating geometry match that expectation. With GCA44DTKS, also verify the card edge bevel, copper-to-edge setback, and plating finish, because those details affect insertion force, contact wipe, and long-term retention more than thickness alone.
Can GCA44DTKS be used when the mating card carries mixed-voltage signals or separate power rails?
GCA44DTKS can be used in mixed-signal or mixed-voltage designs, but the limiting factor is usually the card’s pin assignment and spacing strategy, not the connector body itself. For GCA44DTKS, engineers should check creepage, clearance, return-path placement, and pin sequencing so that power and I/O rails do not create hot-plug stress or unwanted coupling on adjacent contacts.
What should I check if I want to replace an existing card edge connector with GCA44DTKS?
When replacing an existing connector with GCA44DTKS, confirm the mating card thickness, row count, footprint, mounting hole pattern, and keepout around the side-mount opening. Even when the pin count seems equivalent, GCA44DTKS may differ in termination geometry or flange details, which can force PCB layout changes or alter card retention during assembly.
Is GCA44DTKS a good choice for industrial equipment that runs continuously at elevated temperature?
GCA44DTKS is rated for -65°C to 125°C, which makes it suitable for many industrial environments, but the system-level temperature profile still matters. In continuous-duty equipment, designers should account for PCB expansion, vibration, and contact normal-force relaxation over time, and they should validate performance at the actual enclosure temperature rather than only at ambient room conditions.
How does the gold plating on GCA44DTKS affect signal reliability in harsh or low-level signal applications?
The 30.0 µin gold finish on GCA44DTKS helps support stable contact resistance and corrosion resistance, which is useful for low-level signals and intermittent service environments. For GCA44DTKS, the practical consideration is whether the mating edge plating and insertion cycles are compatible with the expected wear level, since repeated abuse or contamination can still degrade contact quality.
Can GCA44DTKS be used for hot-swappable modules or should I avoid that approach?
GCA44DTKS can be used in some removable-card systems, but hot-swap behavior depends on the surrounding power-sequencing and protection circuitry. For GCA44DTKS, designers should include staged pin sequencing, current limiting, and ESD control if the card may be inserted under power; otherwise, transient stress can damage downstream logic even when the connector itself is mechanically sound.
What are the main risks when routing high-speed signals through GCA44DTKS?
With GCA44DTKS, the main concerns are not just connector continuity, but impedance discontinuity, crosstalk between adjacent contacts, and return-path interruption across the card edge. For higher-speed links, keep the pinout symmetric where possible, place grounds strategically, and validate the channel with the connector included in the full interconnect model before locking the design.
Is GCA44DTKS appropriate for vibration-prone systems such as control cabinets or field instruments?
GCA44DTKS can work in vibration-prone equipment when the PCB is mechanically supported and the card edge is retained properly, but the connector alone is not the full solution. Engineers should check board support, fastener strategy, and enclosure dynamics, because repeated micro-motion can increase fretting on any card edge contact over time.
If I need an alternative to GCA44DTKS, what should I compare first?
When evaluating alternatives to GCA44DTKS, compare card thickness support, contact style, plating thickness, row geometry, and PCB footprint compatibility before comparing catalog pin counts. In practice, a substitute may look similar on paper but still require a different board cutout or create a different insertion profile, which affects both assembly and field replacement.
Does GCA44DTKS have any special constraints for PCB layout around the mounting area?
GCA44DTKS uses through-hole solder termination and a side mount opening with a 0.125" diameter flange feature, so the local PCB layout needs enough room for soldering, mechanical clearance, and edge access. For GCA44DTKS, it is common to verify hole tolerances, edge distance, and solder fillet access early, because these details can constrain adjacent component placement.
How should I think about GCA44DTKS for long-life systems where maintenance access is limited?
For long-life systems, GCA44DTKS is typically chosen when a robust mechanical interconnect is needed and field service access is infrequent. The reliability outcome depends on contact cleanliness, controlled insertion cycles, and environmental sealing at the assembly level, so designers often pair GCA44DTKS with conservative derating and service-friendly board retention methods.
Can GCA44DTKS be used with a custom card edge that has only one populated side?
GCA44DTKS is a dual-edge connector, so it is intended for cards that engage both sides of the contact rows. If a custom board only uses one side, GCA44DTKS may still physically mate, but the electrical and mechanical match is not ideal; it is better to confirm the edge geometry and contact usage so unused contact areas do not create alignment or reliability issues.
