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 verify that 342-034-542-103 will fit my PCB card edge and not damage the fingers during insertion?
For 342-034-542-103, confirm the card thickness stays within 0.054" to 0.070" (1.37mm to 1.78mm) and that the edge finish matches a single-edge, 34-position female connector with 0.100" pitch. The cantilever contacts and 10.0µin gold finish are intended for repeated mating, but the card edge should be clean, burr-free, and dimensionally stable to avoid uneven contact force or wear.
Can 342-034-542-103 be used when the signal needs a single-row edge connector with wire-wrap termination instead of a solder tail?
Yes, 342-034-542-103 is a single-row, 34-position card edge connector with wire-wrap termination and through-hole mounting. It is suited to wire-wrap backplane or harness-style assemblies where the board interface is fixed and the wiring is brought out separately, rather than designs that require compact SMT termination.
What design checks matter when replacing another 34-position edge connector with 342-034-542-103?
When evaluating 342-034-542-103 as a replacement, compare the card thickness window, pitch, row count, readout direction, and termination style first. A part that shares 34 positions and 2.54mm pitch may still differ in edge geometry, retention method, mounting footprint, or contact style, so the existing PCB outline and insertion depth need to be checked before assuming interchangeability.
Is 342-034-542-103 suitable for industrial equipment that sees vibration and temperature cycling?
342-034-542-103 is specified for -40°C to 105°C operation, which supports many industrial environments. For vibration or thermal cycling, the actual result depends on how the board is mechanically supported, whether the flush-mount floating bobbin feature is used effectively, and whether the harness or backplane strain is controlled so the connector is not carrying mechanical load.
What are the main risks if I use 342-034-542-103 with a card outside the recommended thickness range?
With 342-034-542-103, a card that is too thin may not maintain stable contact pressure, while a card that is too thick can increase insertion force and stress the cantilever contacts. Either case can affect retention, contact resistance, and long-term wear, so the edge thickness should stay within the listed 0.054" to 0.070" range.
Can 342-034-542-103 be used as a migration option from a different brand’s 34-pin single-edge connector?
342-034-542-103 can be considered for migration only if the mating card edge, footprint, and termination scheme match the target system. Even when another 34-pin single-edge connector appears similar, differences in contact wipe, board support, mounting hole placement, and wire-wrap implementation can require mechanical changes or requalification.
How does the gold contact finish on 342-034-542-103 affect long-term reliability?
The 10.0µin gold finish on 342-034-542-103 is used to improve contact stability and reduce surface oxidation at the mating interface. In long-term service, that helps preserve signal continuity, but reliability still depends on insertion environment, contamination control, and whether the connector is operated within its mechanical and temperature limits.
Is 342-034-542-103 a good choice if I need high-density routing or more than one card edge row?
342-034-542-103 is a single-row, 34-position connector, so it is better aligned with straightforward edge interfaces than with higher-density layouts. If the design needs multiple rows, additional I/O, or tighter pin packing, a different connector family may be more appropriate because the single-row geometry sets the routing and board-space envelope.
What should I check before using 342-034-542-103 in a new design with a custom backplane or harness?
For 342-034-542-103, verify the PCB hole pattern for through-hole mounting, the wire-wrap access clearance, the insertion direction, and the floating bobbin flange dimensions. Those mechanical details often govern whether the connector can be placed near other components or along a crowded backplane without interfering with assembly or service access.
Are there any practical reasons not to choose 342-034-542-103 for a low-profile SMT-only assembly?
342-034-542-103 uses through-hole mounting and wire-wrap termination, so it is not a natural fit for a low-profile SMT-only process. If the assembly is optimized for reflow-only manufacturing, a surface-mount edge connector may reduce process complexity and board handling compared with this part.
What kind of signal or power use cases are realistic for 342-034-542-103?
342-034-542-103 is a 34-position card edge connector with cantilever contacts and gold plating, which makes it suitable for general interconnect use where the mating interface must remain mechanically stable. The final signal or power suitability still depends on the system’s current, spacing, and integrity requirements, so the connector should be matched to the actual electrical loading rather than position count alone.
How should I evaluate 342-034-542-103 for replacement in equipment that may be serviced years later?
For 342-034-542-103 in serviceable equipment, preserve the exact mechanical references: card thickness, connector orientation, mounting style, and edge geometry. That helps avoid future sourcing surprises, because a connector that is electrically similar today can become mechanically incompatible later if the service part number or footprint assumptions are not documented with the build.
