Aluminium Housed Resistors High Power Wirewound Resistors Chassis Mount Power Resistors, Low Standard Induction Resistance, High Stability, Strong Architecture.
Product Parameters：
- Rated Power: 5W ~ 500W (With heat sink).
- Resistance Range: 0.01Ω to 82KΩ.
- TCR: Options ranging from ±20 to ±350 ppm/°C depending on model.
- Withstand Voltage: Up to 2500V
- Wide Temperature Tolerance: Operating range from -55°C to +275°C
- High Precision: Resistance tolerance as low as ±1%
Product Features:
- Superior Thermal Management (Chassis Mount): Designed for direct mounting on a metal chassis or heatsink to utilize the"heat-sink effect,"enabling high power dissipation within a compact physical footprint.
- Rugged Encapsulated Construction: Features a housing that provides total environmental protection against moisture, dust, and contaminants.
- High Power-to-Volume Ratio: Capable of handling significant wattage (typically 5W to 500W) while maintaining a small size, making it ideal for space-constrained enclosures.
- All-Welded Structural Integrity: Internal resistive elements are fully welded to the terminals rather than soldered, ensuring maximum reliability under mechanical vibration and thermal shock.
- Exceptional Stability and Precision: Offers excellent long-term stability (typically <1% resistance change) and is available in tight tolerances (as low as ±1%) with low Temperature Coefficient of Resistance (TCR).
- High Dielectric Strength: Engineered with high-grade insulation materials to provide superior voltage withstanding capability (often up to 2500V or more) between the resistive element and the aluminium case.
- Ayrton-Perry Non-Inductive Winding: Available in non-inductive (NI) styles for high-frequency applications, minimizing reactive components and signal distortion.
- Broad Operating Temperature Range: Proven performance in extreme environments, with an operational range typically spanning from -55°C to +275°C.
