IRC OAR1R100FLF Res Metal Film 0.1 Ohm 1W 20ppm/C Bare Metal RD
Enhance your electronic designs with the IRC OAR1R100FLF, a high-precision metal film resistor designed for current sensing applications. Manufactured by TT Electronics, this resistor offers reliable performance with tight tolerances and excellent thermal stability.
Temperature Cycling (-40°C to +125°C for 1000 cycles): ∆R/R < 1%
Thermal Performance
The resistor's unique construction isolates the hotspot temperature from the circuit board, preventing damage and reducing thermal stress. Thermal images at rated power levels show hotspot temperatures up to 230°C for 5mΩ variants, with solder joint temperatures significantly lower, ensuring circuit integrity.
Power Derating and Surge Capabilities
The OAR series withstands higher operating temperatures than typical design models, with robust metal alloy construction capable of enduring temperatures exceeding 300°C. Surge current capabilities are high due to the metal's heat carrying capacity and cross-sectional area, making these resistors suitable for pulse and surge applications.
For detailed surge current ratings and testing, refer to the datasheet or contact TT Electronics.
Additional Information
Resistors are supplied in bulk packaging of 500 units. For ordering, use the provided part numbers and specifications. Contact TT Electronics for custom resistance values or tolerances.
