Axial Vitreous Leaded Wirewound Resistors with CECC Approval,

Available with Established Reliability

The FDG, FDK and FDP resistors, with completely welded

construction, are the perfect choice for high continuous

power dissipation up to 11.5 W. The established reliability

and failure rate level E0 and E7 is demonstrated within

CECC qualification. The components of this series are well

suited for harsh environments and exhibit a long lifetime.

With their high pulse power capability, they are the ideal

choice for inrush limiters. Typical applications include but

are not limited to power supplies, voltage dividers, AC filters,

and snubber resistors. Particular requirements can be

submitted to a Vishay Draloric application engineer

specifying peak voltage, pulse shape, pulse duration, and

environmental conditions for review.

FEATURES

• CECC 40201-801 approval options:



- Version A, failure rate level E0



- Version E, with established reliability, failure



rate level E7

• High power dissipation in a small design

• Excellent pulse load capability

• Vitreous coating

• Non-flammable and enhanced humidity protection

• Material categorization: for definitions of compliance

APPLICATIONS

• Inrush current limiter

• Power supplies

• Snubber resistor

• Filter resistor

Notes

• The operating temperature range for these resistors is from -55 °C up to 350 °C

and thus may be used as a replacement
