End-of-Life Vishay Phoenix Product
FEATURES
- High power dissipation in small volume
- Completely welded construction
- Fire proof inorganic construction
- Formed leads available on request
- Film resistors version available on request
- Long leads available For closest Vishay Dale equivalent, please contact: ww2aresistors@vishay.com Note:
- There may be slight differences between the Vishay Phoenix and the Vishay Dale crosses TECHNOLOGY The resistor element is a resistive wire, which is wound, on ceramic rod. Tinned copper leads are connected to the caps by welding. The re sistor body are housed in a rectangular ceramic case with a special inorganic potting which is non-flamm able, will not melt even at high overload s and is resistant to most commonly used cleaning solvents and moisture.

End-of-Life Vishay Phoenix Product MARKING The resistor is marked with th e resistor type designation, nominal resistance value, tolerance, rated power and the production date (week and year), in red on the resistor body. Example: AMW07S - 5.1 kΩ - 5 % - week 02 - year 2005 Example: Last Digit of Ordering Code The resistors have 12 digit ordering code starting with 2306. The next 5 digits indicate the resistor type and packaging, see table ORDERING INFORMATION. The last 3 digits indicate the resistance value: - The first 2 digits of these last 3 indicate the actual resistance value - The last digit indicates the resistance decade in accordance with table “Last Digit of Ordering Code” Example: AMW03S, 100 Ω, 5 %, flat case, box of 250 pieces is 2306 270 13101 PHX AMW07S 502 5K1 5 % 7 W
