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

Can 833-037-520-103 fit a 1.6 mm PCB edge card, or do I need to check more than the nominal thickness?
833-037-520-103 is specified for a card thickness range of 0.054" to 0.070" (1.37 mm to 1.78 mm), so a standard 1.6 mm PCB usually falls within the intended window. In practice, you should also verify edge bevel, plating on the card fingers, and the insertion lead-in on the mating connector, because those details affect insertion force and contact wipe more than thickness alone.
Is 833-037-520-103 suitable if my design needs a rugged through-hole edge connector for industrial equipment?
833-037-520-103 uses through-hole solder terminations, which generally gives better mechanical anchoring than surface-mount styles when the board sees handling, vibration, or repeated insertions. For industrial use, the remaining checks are PCB hole quality, solder fillet coverage, and whether the card is supported so the connector is not carrying bending loads by itself.
What should I verify before replacing an older 37-position, 0.156-inch single-edge connector with 833-037-520-103?
With 833-037-520-103, the key migration checks are pin count, pitch, single-edge orientation, card thickness window, and mounting footprint. Even when those match, older parts often differ in tail length, retention features, and insertion depth, so it is best to compare the mechanical drawing and keep-out zone before assuming drop-in compatibility.
Does 833-037-520-103 work for low-level signals, or is the contact system better suited to power or general interconnects?
833-037-520-103 uses gold-plated copper alloy contacts, which is a common choice when stable contact resistance is needed for signal or mixed-signal boards. For very low-level analog or high-impedance lines, the connector can work well if the card edge finish is clean and the system is protected from contamination, but the final decision should still consider contact force, wipe length, and the noise environment.
How does the gold finish on 833-037-520-103 affect long-term reliability in a design that is inserted and removed periodically?
833-037-520-103 has 10 µin gold on the contact finish, which helps resist oxidation and supports more consistent mating behavior than tin-only contacts in many environments. If the board will be cycled often, the practical limits are usually wear on the card fingers, fretting from vibration, and contamination rather than the base metal itself.
Is 833-037-520-103 appropriate for environments with wide temperature swings or continuous elevated temperature operation?
833-037-520-103 is rated from -40°C to 125°C, so it can be considered for equipment that experiences outdoor or industrial thermal variation. For continuous elevated-temperature operation, the surrounding assembly still matters: verify solder joint reliability, PCB material glass transition behavior, and whether the mating card materials remain dimensionally stable across the full range.
What design constraints should I watch for when laying out the PCB around 833-037-520-103?
833-037-520-103 uses a flush-mount, floating-bobbin flange feature, so the board should allow for the connector body, flange, and insertion path without mechanical interference. The PCB layout should also account for through-hole pad geometry, annular ring strength, and any chassis or panel alignment needed to avoid side-loading the connector during card insertion.
If I need a different mounting or termination style, can I use another part in the 833-037 family instead of 833-037-520-103?
Yes, 833-037-520-103 is one member of the 833-037 family, and the family naming suggests related variants may exist with different tail, mounting, or packaging options. When selecting a substitute, confirm that the mating geometry, board thickness range, and retention method still match the system, because a family-matched part is not automatically a mechanical drop-in.
