KWX Wirewound Resistors FPE

Product catalog summary

Features and Specifications
1. The FPE-0 series includes wirewound resistors with a power rating ranging from 2.5W to 8W.
2. Resistance tolerance options are ±5% (J) and ±10% (K).
3. Resistance values are specified in ohms, e.g., 100R for 100Ω.
4. The resistors are constructed with a fiberglass substrate, silicone coating, and flame-retardant properties.
5. They are safe, reliable, and have character marking for identification.

Construction Details
1. Alloy resistance wire wound on a fiberglass core or ceramic substrate.
2. Mechanically crimped tin-plated PCB type termination.
3. Flame retardant silicone coating ensures safety.

Dimensions and Weight
1. Dimensions vary with power rating, e.g., 10.2mm to 45.7mm in length.
2. Typical weight per piece ranges from 1.05g to 2.91g depending on the power rating.

Performance and Ratings
1. The resistors operate within a temperature range of -55℃ to +350℃, with derating required as per the derating curve.
2. Voltage ratings vary based on resistance value and overload conditions.
3. Dielectric withstanding voltage is based on limiting voltage x 2 for 60 seconds.
4. Short time overload and temperature cycling tests show minimal resistance change.

Environmental and Mechanical Tests
1. Damp heat and endurance tests show resistance changes within specified limits.
2. Solvent resistance and solderability meet IEC standards.
3. Terminal tensile strength is rated at 40 Newtons.

Ordering Information
1. Specify the series name, power rating, resistance tolerance, and resistance value when ordering.
2. Options for longer or shorter stand-off terminals are available by suffixing the type with '0' or '1'.
