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

How do I confirm whether 337-056-523-804 is compatible with my 1.6 mm card thickness and connector keepout?
The 337-056-523-804 is specified for card thicknesses from 0.054" to 0.070" (1.37 mm to 1.78 mm), so a nominal 1.6 mm board is within range. For 337-056-523-804, verify the finished thickness after solder mask, plating, and any local fabrication tolerances, and check the edge bevel and lead-in geometry so the card fully seats without excessive insertion force or contact stress.
Can 337-056-523-804 be used in a mixed-voltage backplane or system where the mating card I/O levels differ from the connector system voltage?
337-056-523-804 is a passive interconnect, so the connector itself does not translate voltage levels. For 337-056-523-804, mixed-voltage compatibility depends on the card circuitry, creepage and clearance on the PCB, and whether adjacent signals can tolerate the chosen routing and pin assignment. The gold-plated contacts support reliable signal transfer, but the system design still needs proper level shifting, protection, and grounding.
What should I check before replacing a legacy dual-edge card connector with 337-056-523-804?
When replacing an existing part with 337-056-523-804, compare the edge contact pitch, dual-row geometry, card thickness window, mounting-hole pattern, and top-mount opening dimensions against the original footprint. For 337-056-523-804, also verify mating depth, contact wipe, and retention behavior, since a connector that looks similar can still change insertion force, alignment, or signal integrity enough to affect field reliability.
Is 337-056-523-804 suitable for industrial equipment exposed to vibration and temperature cycling?
337-056-523-804 is rated from -40 C to 105 C, which fits many industrial environments from a temperature standpoint. For 337-056-523-804, the more practical questions are board support, solder joint robustness, and whether the card is restrained against micro-motion. The through-hole solder termination helps with mechanical stability, but long-term vibration performance still depends on the enclosure, anchoring, and PCB stiffness.
How does the gold contact finish on 337-056-523-804 affect low-level signal or intermittent-contact issues?
The 10.0 uin gold finish on 337-056-523-804 is typically chosen to improve corrosion resistance and maintain stable contact resistance over repeated mating cycles. For 337-056-523-804, this helps when the system carries low-level signals that are sensitive to oxide films or minor contamination. If intermittent contact appears, the cause is often card-edge wear, contamination, or alignment error rather than the finish alone.
Can 337-056-523-804 be used for a high-current power path, or is it better suited to signal routing?
337-056-523-804 is a 56-position card edge connector, so current handling depends on how many contacts are assigned to power and how the PCB dissipates heat. For 337-056-523-804, it is generally safer to distribute power across multiple contacts, confirm the current rating from the full connector data, and avoid concentrating load on a single pin. Systems with sustained high current or hot-plug stress usually need a dedicated power connector.
What mounting or panel constraints should I plan for when designing around 337-056-523-804?
337-056-523-804 uses through-hole solder termination and a top-mount opening with an unthreaded 0.156" diameter flange feature. For 337-056-523-804, the PCB layout should reserve solder access, wave or selective solder clearance, and enough mechanical support around the connector body so the card insertion force does not distort the board. If the assembly sits near a chassis wall or shielding can, check the opening and standoff height early in the layout.
Are there practical substitutes for 337-056-523-804 if I need a different edge pitch or card format?
If the system cannot use the 0.156" pitch or the dual-edge card format of 337-056-523-804, you would typically look for another card edge connector family that matches the mechanical envelope and contact arrangement of the target board. For 337-056-523-804, a substitute only works if the mating card thickness, row count, contact orientation, and mounting pattern all line up; otherwise the redesign can cascade into PCB, enclosure, and harness changes.
How should I evaluate 337-056-523-804 for long-life service where connectors may be mated and unmated repeatedly?
For 337-056-523-804, repeated mating life depends on contact wear, contamination control, and whether the card edge is properly chamfered and clean. The gold finish helps reduce oxidation, but 337-056-523-804 still needs controlled insertion alignment and a card-edge finish that avoids burrs. In long-life systems, it is common to validate mating endurance with the actual board surface finish, humidity exposure, and handling process rather than relying on the connector alone.
Does 337-056-523-804 require any special handling for storage, assembly, or moisture exposure?
337-056-523-804 has MSL 1, so it does not require moisture-bake handling typical of moisture-sensitive packages. For 337-056-523-804, standard ESD-safe handling, contamination control, and dry storage are still good practice, especially before soldering. The polyester thermoplastic housing and copper-alloy contacts should be kept free of flux residue and debris so mating quality remains consistent after assembly.
