FEATURES
• High power dissipation in small volume
• Ideal for pulsing applications
• Stand-up mounting saves space on PCB
• High heat and moisture resistance
Please reference the Vishay Dale closest equivalents: CPCx or CPCC, CPCF High Volume (for CPCx datasheet please
visit our website: http://www.vishay.com/doc?30218 and for CPCC, CPCF High Volume datasheet:
http://www.vishay.com/doc?30116).
Note:
• There may be slight differences between the Vishay Phoenix and the Vishay Dale crosses
TECHNOLOGY
SMW: The resistor element is a resistive wire, which is wound in a single layer on a ceramic rod. Metal caps are pressed over
the rod. The ends of the resistive wire and the leads are connected to the caps by welding.
SMF: The resistor element is a metal film resistor consisting of a metal layer deposited over a high-grade ceramic rod. Metal
caps are pressed over the rod. The leads are connected to the caps by welding.
For both SMW and SMF, the resistor body and lead ends are housed within a rectangular ceramic case which is non-flammable,
will not melt even at high overloads and is resistant to most commonly used cleaning solvents, in accordance with MIL-STD-202,
method 215 and IEC 60 068-2-45. A special version with a thermal fuse for surge and inrush current protection is available upon
request.
