- RoHS and REACH compliant with lead-free termination, compatible with standard lead-free reflow soldering processes
What is RT0603FRE135K11L used for?
The RT0603FRE135K11L is used in precision voltage dividers, instrumentation amplifier gain-setting networks, and analog-to-digital converter reference resistor ladders where stable 5.11 kΩ resistance with low drift is required. Its 50 ppm/°C TCR ensures resistance change of less than 0.25% across a -40°C to +85°C industrial temperature range, supporting accurate measurement in medical devices, test equipment, and sensor signal chains. The 0603 SMD form factor integrates easily into high-density precision analog PCB layouts.

Frequently Asked Questions
What makes RT0603FRE135K11L suitable for precision measurement circuits compared to thick film alternatives?
The RT0603FRE135K11L uses thin film construction achieving a 50 ppm/°C temperature coefficient of resistance (TCR), which is 2 to 4 times tighter than typical thick film resistors at 100 to 200 ppm/°C. Combined with 1% initial tolerance, this ensures the 5.11 kΩ resistance drifts by less than 0.25% across a -40°C to +85°C range, critical for low-offset instrumentation amplifier and ADC reference networks.
How does the 0603 package size of RT0603FRE135K11L affect placement on high-density analog PCBs?
The 0603 package measures 1.6 mm × 0.8 mm × 0.45 mm, fitting standard IPC 0603 land patterns with a courtyard of approximately 2.0 mm × 1.2 mm. This allows up to 4 resistors per cm² on a dense analog layout, enabling compact precision gain networks, filter ladders, and divider chains without switching to less-standard 0402 components that are harder to inspect and rework.
For a transimpedance amplifier feedback network, why is the 50 ppm/°C TCR of RT0603FRE135K11L important?
In a transimpedance amplifier, the feedback resistor directly sets the current-to-voltage gain. A 50 ppm/°C TCR resistor like RT0603FRE135K11L limits gain drift to approximately 0.005% per °C, compared to 0.01% to 0.02% per °C for standard thick film parts. Over a 60°C operating range, this reduces gain error from thermal variation to well under 0.3%, maintaining signal chain accuracy for photodiode or current sensor measurements.
How does RT0603FRE135K11L compare to a standard YAGEO RC0603 series resistor for cost-sensitive designs?
The RT0603FRE135K11L thin film resistor with 50 ppm/°C TCR and 1% tolerance costs more per unit than the RC0603 thick film series, which typically offers 100 to 200 ppm/°C TCR at 1% tolerance. However, in precision voltage dividers operating over a 25°C to 85°C range, the thin film part reduces system-level calibration effort and error correction overhead, which can offset its higher unit price in instruments requiring less than 0.1% gain error.
