End-of-Life Vishay Phoenix Product

FEATURES

• High power dissipation in small volume

• Ideal for pulsing applications

• Completely welded construction

• Non-flammable

• High heat and moisture resistance

• Low inductance version available on request

Please reference the Vishay Dale closest equivalents: CP, CP High Volume (for CP datasheet please visit our website:

http://www.vishay.com/doc?30213 and for CP High Volume datasheet: http://www.vishay.com/doc?30113).

Note:

• There may be slight differences between the Vishay Phoenix and the Vishay Dale crosses

TECHNOLOGY

AMW: The resistor element is a resistive wire, which is wound on a ceramic rod.

AMF: The resistive element is a metal film resistor consisting of a metal layer deposited over a high grade ceramic rod.

For both AMW and AMF, tinned copper leads are connected to the caps by welding. The resistor body is housed in a rectangular

ceramic case with a special, inorganic potting which is non-flammable, will not melt even at high overloads and is resistant to

most commonly used cleaning solvents.

Notes:

(1) Special resistance values available upon request

(2) Other tolerances available upon request

Note:

(3) Temperature Coefficient of ± 30, 50 or 90 ppm/ºC available on AMW upon request
