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 I use RWR80S7320FPBSL as a drop-in replacement if my circuit currently uses a 750 ohm or 730 ohm axial resistor?
RWR80S7320FPBSL is a 732 ohm, ±1% wirewound resistor, so it is not a direct electrical match for 730 ohm or 750 ohm parts. In bias, sense, or feedback networks, that difference can shift gain, current limit, or calibration enough to matter. A replacement with RWR80S7320FPBSL works best when the design tolerates the exact 732 ohm value and the wirewound behavior, not just the physical axial form factor.
Is RWR80S7320FPBSL suitable for high-temperature industrial equipment that runs near 200°C?
RWR80S7320FPBSL is rated from -55°C to 250°C, which makes it suitable for elevated-temperature environments when the rest of the assembly can also handle that range. In practice, the resistor’s full 2 W rating still depends on board layout, lead length, airflow, and nearby heat sources. For continuous high-temperature service, verify the derating curve and the enclosure thermal profile rather than relying on ambient rating alone.
What should I check before using RWR80S7320FPBSL in a precision current-sense or calibration circuit?
RWR80S7320FPBSL has a ±20 ppm/°C temperature coefficient and ±1% tolerance, so it can support stable ratios better than general-purpose resistors. The main design check is whether wirewound construction is acceptable, since it may introduce small inductive behavior that matters in fast-changing or high-frequency sensing paths. For low-frequency or DC calibration networks, RWR80S7320FPBSL is usually a practical fit.
Can RWR80S7320FPBSL be used where low inductance is required?
RWR80S7320FPBSL is a wirewound resistor, so it is not the first choice for circuits that need very low parasitic inductance. If the application involves fast edges, RF, pulse shaping, or broadband feedback, the winding geometry can affect impedance versus frequency. For those cases, a non-inductive resistor technology may be a better design match than RWR80S7320FPBSL.
How do I know if RWR80S7320FPBSL can handle the dissipation in my design?
RWR80S7320FPBSL is rated at 2 W, but actual usable dissipation depends on ambient temperature, mounting method, and lead spacing. In sealed or crowded enclosures, the resistor may need derating well below 2 W to stay within safe temperature rise limits. It is common to size with margin when RWR80S7320FPBSL is used in dropper, bleed, or load-sharing positions.
Is RWR80S7320FPBSL appropriate for replacing a carbon film resistor in an older industrial system?
RWR80S7320FPBSL can be a good replacement when the original part failed from drift, heat, or moisture exposure, because the military moisture-resistant wirewound construction is generally more robust than basic carbon film parts. The trade-off is that its electrical behavior is different, especially in inductive response and long-term value stability. Before substituting RWR80S7320FPBSL, confirm that the circuit is not sensitive to resistor noise, frequency response, or leaded axial dimensions.
What design issues come up when I mount RWR80S7320FPBSL on a PCB?
RWR80S7320FPBSL is an axial through-hole part, so it needs sufficient pad spacing and mechanical support for the leaded body. Designers should check board hole diameter, lead forming, creepage and clearance, and whether the resistor will sit elevated or laid down for thermal reasons. If the assembly sees vibration, adding mechanical support or strain relief helps protect RWR80S7320FPBSL and its solder joints.
Can RWR80S7320FPBSL be used in moisture-prone or harsh-environment equipment?
RWR80S7320FPBSL is specified as moisture resistant, which makes it suitable for equipment exposed to humidity or challenging field conditions. That said, moisture resistance does not replace good enclosure design, conformal coating decisions, or corrosion control at the assembly level. For long-life outdoor or industrial systems, RWR80S7320FPBSL is typically paired with proper PCB protection and controlled soldering processes.
What should I compare if I am selecting between RWR80S7320FPBSL and a standard metal film resistor?
RWR80S7320FPBSL offers a military-grade, moisture-resistant wirewound construction, while a metal film resistor may offer lower inductance and a different frequency response. If your circuit is DC-heavy, power-dissipating, or exposed to harsh conditions, RWR80S7320FPBSL can be a strong fit. If your circuit depends on low noise at higher frequencies or very low parasitics, the alternative technology may be easier to integrate.
Is RWR80S7320FPBSL a good choice for long-term reliability in mission-critical assemblies?
RWR80S7320FPBSL belongs to the MIL-PRF-39007 RWR80S family and carries a P failure rate designation, which indicates a screened reliability class for demanding use. In practical terms, that makes it a common selection for environments where part drift, moisture exposure, and extended service life are part of the design envelope. Final suitability still depends on operating temperature, dissipation, and the end-equipment qualification plan.
