Overview
The TE Connectivity RP73PF2A121KBTDF is a high-precision 121 kΩ thin-film surface-mount resistor, engineered for demanding applications where tight tolerance and stability are paramount. Its 0.1% absolute tolerance and 25 ppm/°C temperature coefficient ensure minimal drift across its -55°C to +155°C operating range, making it ideal for sensitive analog circuitry. A critical design consideration for such precision components is the trade-off between power handling and component size; while rated at 250 mW, engineers must carefully manage thermal dissipation in dense PCB layouts to maintain the specified accuracy and prevent premature component degradation.
Key Features
- Resistance: 121 kOhms
- Tolerance: ±0.1%
- Temperature Coefficient: ±25 ppm/°C
- Power Rating: 250 mW (1/4 W)
- Maximum Operating Temperature: +155°C
- Dimensions: 2.0 mm x 1.25 mm x 0.55 mm (0805/2012 case)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Precision voltage division in sensor signal conditioning circuits.
- Gain setting for low-noise operational amplifiers in instrumentation.
- Reference voltage generation for high-resolution analog-to-digital converters (ADCs).
- Current sensing in high-efficiency power management modules.
