RT73 Series Thick Film Precision Resistor – 10K Variant

Note: The RT73 series consists of passive resistor components (0402, 0603, 0805, 1206 packages). These are two-terminal devices with no "pins" in the traditional sense — only two solder terminals (one at each end). There is no pin diagram showing numbered pins because resistors do not have numbered pin assignments.

The "10K" designation refers to the resistance value (10,000 Ω), not a specific package variant. The 10K value is available across all four package types:

• RT73 1E (0402 package)
• RT73 1J (0603 package)
• RT73 2A (0805 package)
• RT73 2B (1206 package)

Pinout Table

Notes

• No numbered pins exist for this component. Resistors are two-terminal passive devices with solder pads at each end.
• The "10K" specification refers to the nominal resistance value of 10,000 Ω (10 kΩ).
• Actual tolerance, temperature coefficient, and power rating depend on the specific package variant selected (1E, 1J, 2A, or 2B).
• For the 10K value, all variants support ±0.1%, ±0.25%, ±0.5%, or ±1.0% tolerance options (code letters B, C, D, E respectively).
• Operating temperature range: −55 °C to +150 °C for all variants.
• Maximum operating voltage varies by package: 75 V (1E), 100 V (1J), 150 V (2A), 200 V (2B).
