What are the key features of MC0063W0603178K7?
- 78.7 kΩ resistance value with 1% tolerance enables precise voltage divider ratios and accurate biasing in analog signal chains
- 0.063 W rated power dissipation in a compact 0603 SMT package (1.6 mm × 0.8 mm × 0.45 mm) suits low-power circuit designs
- Thick-film rectangular construction provides stable resistance values over standard commercial operating temperature ranges for reliable performance
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place assembly in high-volume production runs
What is MC0063W0603178K7 used for?
The MC0063W0603178K7 is used in voltage divider networks, pull-up/pull-down biasing, and ADC input scaling circuits in consumer electronics, embedded systems, and IoT devices where a precise 78.7 kΩ ±1% resistor is required. Its compact 0603 form factor suits high-density PCB layouts in smartphones, wearables, and sensor modules where board space is at a premium. Engineers also specify this resistor in feedback networks for op-amp stages and low-power current limiting applications operating at 3.3 V or 5 V supply rails.

Frequently Asked Questions
What resistance value and tolerance does the MC0063W0603178K7 provide, and how accurate is it for voltage divider designs?
The MC0063W0603178K7 has a nominal resistance of 78.7 kΩ with ±1% tolerance, meaning the actual resistance will be between 77.91 kΩ and 79.49 kΩ. In a two-resistor voltage divider on a 3.3 V rail, this ±1% accuracy limits the output voltage error to approximately ±33 mV — acceptable for most ADC input scaling designs with 8-bit or 10-bit resolution.
For an IoT sensor node running on a 3.3 V battery supply, how much power does the MC0063W0603178K7 dissipate in a pull-up configuration?
As a pull-up resistor on a 3.3 V rail, the MC0063W0603178K7 (78.7 kΩ) dissipates approximately 138 µW (P = V²/R = 3.3²/78700). This is well within the 0.063 W (63 mW) rated power dissipation, leaving a comfortable 99.8% derating margin. In an IoT node where the pull-up is always powered, this 138 µW load is negligible compared to the sensor or radio module current draw.
What physical size is the 0603 package of MC0063W0603178K7, and does it suit automated PCB assembly?
The 0603 SMT package measures 1.6 mm × 0.8 mm × 0.45 mm (L × W × H), which is compatible with standard automated pick-and-place machines operating with nozzle diameters down to 0.5 mm. The tape-and-reel (TR) packaging of the MC0063W0603178K7 feeds directly into industry-standard SMT feeders, enabling high-speed placement at rates exceeding 10,000 components per hour on modern assembly lines.
When is the MC0063W0603178K7 a better choice than a similar 0402 resistor for a low-power analog front end?
The 0603 package of MC0063W0603178K7 is preferred over 0402 when hand-rework, selective soldering, or manual inspection of solder joints is anticipated during prototyping or low-volume production. The 0.45 mm height and 1.6 mm body length allow visual confirmation of solder fillet quality under a microscope without the 0402's sub-1 mm body making inspection difficult. For designs under 0.063 W dissipation with 1% tolerance at 78.7 kΩ, both package sizes meet the electrical requirement, and the 0603 choice is a reworkability preference.
