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

What design checks should I do before using Fox Electronics FO7HHAAE3.6864-T1 as a drop-in clock source in an existing 5 V HCMOS design?
For Fox Electronics FO7HHAAE3.6864-T1, verify that the receiving logic truly accepts 5 V HCMOS levels and that the input pin is compatible with a push-pull oscillator output. Check the required frequency tolerance, start-up behavior, duty-cycle sensitivity, and input loading of the downstream device. If the old source was a crystal or a different oscillator family, make sure the board does not depend on a sine-wave, open-drain, or tri-state clock behavior, since FO7HHAAE3.6864-T1 is an active oscillator and not a passive resonator.
Can Fox Electronics FO7HHAAE3.6864-T1 be used when the target IC is powered from 3.3 V or lower?
Fox Electronics FO7HHAAE3.6864-T1 is specified as a 5 V HCMOS oscillator, so it is suited to systems that can accept 5 V clock signaling. If the target device is only 3.3 V or lower, check the absolute maximum ratings of the clock input and the board’s supply architecture before using it. In many mixed-voltage designs, a level-compatible clock source or a different oscillator family is a better fit than FO7HHAAE3.6864-T1.
What should I consider if I want to replace a crystal and load capacitors with Fox Electronics FO7HHAAE3.6864-T1?
Fox Electronics FO7HHAAE3.6864-T1 can simplify the clock path because it provides a complete 3.6864 MHz source, so the crystal load network is no longer needed. The main checks are supply voltage, enable or output behavior if your original circuit used a crystal oscillator pin set, and the timing requirements of the connected logic. Also confirm that the board layout supports the oscillator’s power decoupling and that the new output amplitude and edge rate do not create EMI or signal-integrity issues that were absent with the crystal solution.
Is Fox Electronics FO7HHAAE3.6864-T1 suitable for UART baud-rate generation and legacy communications timing?
Fox Electronics FO7HHAAE3.6864-T1 at 3.6864 MHz is often a practical clock choice for serial timing because that frequency divides cleanly into common baud-rate families. For a design-in, verify that the selected divider chain, MCU, or UART block can derive the required baud rates with acceptable error. It is a good fit when the system architecture benefits from a precise fixed reference, but it should still be checked against the specific tolerance budget of the communication link.
How do I evaluate whether Fox Electronics FO7HHAAE3.6864-T1 is appropriate for industrial or always-on equipment?
For Fox Electronics FO7HHAAE3.6864-T1, focus on supply stability, ambient temperature range versus the oscillator’s actual operating envelope, and the clock tolerance needed over time and temperature. In industrial equipment, also review startup time after power cycling, susceptibility to supply noise, and whether nearby switching regulators can modulate the oscillator rail. If the application has long service intervals, the board-level power integrity and clock distribution matter as much as the nominal frequency.
What replacement options should I compare against Fox Electronics FO7HHAAE3.6864-T1 if the exact part is unavailable?
When substituting for Fox Electronics FO7HHAAE3.6864-T1, compare frequency, output type, supply voltage, package footprint, enable pin behavior, and startup characteristics rather than focusing only on 3.6864 MHz. Cross-check phase noise, jitter, rise time, and load compatibility if the clock feeds timing-sensitive logic. A different manufacturer’s 3.6864 MHz 5 V HCMOS oscillator may work, but pinout and output-drive differences often determine whether it is truly interchangeable.
Can Fox Electronics FO7HHAAE3.6864-T1 be used as a replacement in an older design that previously used a TTL clock output?
Fox Electronics FO7HHAAE3.6864-T1 may be usable in older TTL-oriented systems if the receiving logic accepts 5 V HCMOS levels and the clock input thresholds are compatible. The main design check is whether the destination expects TTL-style switching thresholds, because some legacy inputs are forgiving while others are not. Review the input high and low specifications on the target device before assuming the oscillator output can replace the older source directly.
What layout practices help avoid clock issues with Fox Electronics FO7HHAAE3.6864-T1?
For Fox Electronics FO7HHAAE3.6864-T1, keep the supply decoupling capacitor close to the oscillator power pins and route the clock trace away from noisy switching nodes, high-current loops, and sensitive analog nets. Use a short, direct path to the receiving clock input and avoid unnecessary stubs or branching. If the clock trace is long or crosses a noisy section of the board, evaluate whether series damping or a different placement reduces ringing and EMI.
Is Fox Electronics FO7HHAAE3.6864-T1 appropriate for battery-powered designs?
Fox Electronics FO7HHAAE3.6864-T1 is a 5 V HCMOS oscillator, so the first question in a battery-powered design is whether the system already has a regulated 5 V rail. If the product runs primarily at lower voltages, the extra regulation overhead and power consumption may make a different oscillator family more practical. It can still be used where a 5 V domain already exists, but it is not the usual first choice for low-power portable systems.
What should I verify for long-term reliability if I use Fox Electronics FO7HHAAE3.6864-T1 in a production design?
For Fox Electronics FO7HHAAE3.6864-T1, confirm the supply rail quality, thermal environment, and mechanical stability of the assembly over the product’s life. Active oscillators can be sensitive to local heat, solder joint stress, and rail transients, so the board should keep the device away from hot components and high-noise power paths. Since the part is RoHS3 compliant and MSL 1, handling and storage are straightforward, but the operating reliability still depends on the final system’s electrical and thermal conditions.
