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 Vishay Dale CW00512R00JS73 be used continuously at 12 ohms and 6.5 W in a power supply or load circuit?
Vishay Dale CW00512R00JS73 can dissipate up to its rated power only under the manufacturer’s specified thermal conditions. At 6.5 W, the nominal current is approximately 0.74 A and the voltage is approximately 8.83 V, calculated from P = I²R and P = V²/R. PCB copper area, airflow, nearby heat sources, lead spacing, and ambient temperature affect the resistor body temperature, so a thermal derating curve or temperature measurement should be used for continuous operation.
What power-supply voltage and current limits should I calculate before selecting Vishay Dale CW00512R00JS73?
For Vishay Dale CW00512R00JS73, the 12 ohm resistance gives approximately 0.74 A at 6.5 W and approximately 8.83 V at 6.5 W under ideal steady-state calculations. Startup surges, capacitor charging, fault current, and supply tolerance can produce higher stress. The selected circuit should verify continuous power, transient energy, resistor temperature, and the available current-limiting behavior of the power supply.
Is Vishay Dale CW00512R00JS73 suitable for PWM, switching, or other high-frequency circuits?
Vishay Dale CW00512R00JS73 is a wirewound axial resistor, so its winding can introduce parasitic inductance compared with a metal-film or non-inductive resistor. It may work in low-frequency power, braking, discharge, or current-limiting applications, but its impedance, pulse response, and generated electromagnetic noise should be checked before use in fast PWM feedback paths, gate-drive networks, RF circuits, or precision high-speed signal lines.
How should Vishay Dale CW00512R00JS73 be mounted to prevent overheating on a PCB?
Vishay Dale CW00512R00JS73 has an approximately 7.92 mm diameter and 22.22 mm body length. Leave clearance from heat-sensitive components, avoid placing the body against the PCB unless the thermal design allows it, and provide sufficient lead length and spacing for the intended airflow. The resistor’s surface can become substantially hotter than the ambient environment when dissipating several watts, so the assembly should be evaluated under the actual enclosure and airflow conditions.
Can I replace Vishay Dale CW00512R00JS73 with a 5 W or 10 W axial resistor?
A 5 W replacement for Vishay Dale CW00512R00JS73 reduces the available power margin and may overheat during the same load condition. A 10 W axial resistor can provide additional thermal margin, but its body size, lead spacing, resistance tolerance, temperature coefficient, pulse rating, and parasitic inductance may differ. The replacement should meet or exceed the required steady-state and transient ratings while fitting the PCB and enclosure.
What should I check when replacing Vishay Dale CW00512R00JS73 with Ohmite OX5R012J or TE Connectivity SQM5AJB-12R?
When comparing Vishay Dale CW00512R00JS73 with examples such as Ohmite OX5R012J or TE Connectivity SQM5AJB-12R, verify the exact manufacturer datasheet and suffix because resistance, power rating, dimensions, tolerance, temperature coefficient, inductance, pulse capability, and derating may differ. A nominal 12 ohm and 5% match does not establish electrical or mechanical equivalence. RoHS status, lead finish, procurement availability, and qualification documentation also need to match the end product.
Can Vishay Dale CW00512R00JS73 replace a non-wirewound 12 ohm resistor in an analog or measurement circuit?
Vishay Dale CW00512R00JS73 may replace a non-wirewound 12 ohm resistor in a low-frequency power path when its 6.5 W rating and approximately ±30 ppm/°C temperature coefficient meet the circuit requirements. Its wirewound construction can have higher inductance and different voltage-noise behavior than a metal-film or metal-oxide part, which can affect current-sense paths, amplifier compensation, precision filters, and fast transients.
How does the ±5% tolerance of Vishay Dale CW00512R00JS73 affect a current-limiting or load-sharing design?
The resistance of Vishay Dale CW00512R00JS73 can initially range from approximately 11.4 to 12.6 ohms before temperature and aging effects. In a current-limiting circuit, the lower-resistance tolerance value can increase current and power dissipation; in parallel load-sharing circuits, tolerance mismatch can cause unequal current distribution. Calculate circuit behavior at both resistance limits and include the temperature coefficient in the operating-temperature analysis.
Can Vishay Dale CW00512R00JS73 operate in an industrial enclosure with elevated ambient temperature?
Vishay Dale CW00512R00JS73 has a listed operating range of -65°C to 350°C, but the upper temperature value does not by itself establish that the resistor can dissipate 6.5 W at every ambient temperature. The resistor’s own temperature is the combined result of ambient temperature, applied power, mounting orientation, airflow, and neighboring heat sources. Use the manufacturer’s derating information and confirm the hottest operating condition by thermal testing.
Is Vishay Dale CW00512R00JS73 acceptable for a RoHS-controlled product or a long-life regulated design?
Vishay Dale CW00512R00JS73 is listed as RoHS non-compliant and REACH affected, so its material declaration and regulatory status should be reviewed against the destination market and product policy before release. For long-life industrial equipment, also verify resistance drift, solder-joint temperature, moisture exposure, vibration, overload behavior, and supplier continuity. Tape-and-reel packaging supports automated handling, but it does not change the component’s compliance or environmental requirements.
